Cardiovascular Disease And Inflammation

Dr. Mark Houston talked about cardiovascular disease and inflammation – “the evil twins”. He presented this lecture at the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas. Dr. Houston is an associate clinical professor of medicine at the Vanderbilt University Medical School in Nashville, TN 37232.

New thinking about cardiovascular disease and inflammation

Dr. Houston pointed out that the old thinking about cardiovascular disease has to be replaced with the new thinking. Here are a number of points regarding the new thinking.

  1. Coronary heart disease and congestive heart failure are diseases of inflammation. They are also coupled with oxidative stress, vascular immune dysfunction and dysfunction of the mitochondria.
  2. In the past it was difficult to reduce these cardiovascular diseases. With the new thinking there are now new treatment approaches that help cure cardiovascular disease.
  3. The development of heart disease has a long history. Endothelial dysfunction predates coronary artery disease by many years. This is followed by vascular smooth muscle dysfunction. Inflammation develops and structural changes occur in the small and larger blood vessels with atheromatous deposits (plaques) and final occlusion, at which point you get a heart attack.

Canadian physician Sir William Osler has already stated more than 100 years ago “A man is as old as his blood vessels”.

The old thesis was that cholesterol would lead to deposits that close coronary blood vessels and cause heart attacks. Dr. Houston called this the “cholesterol-centric “ approach. The truth is that with conventional blood tests you are missing 50% of all the high-risk patients that are going to develop heart attacks. They are missing the ones that have chronic inflammation, but normal cholesterol levels.

What was not known in the past was that oxidative stress associated with normal aging can lead to chronic low-grade inflammation. This oxidative stress leads to mitochondrial DNA changes. Associated with it are biochemical changes that cause chronic inflammation, which in turn will affect the lining of the arteries. There is a metabolic change described in the literature as metabolic syndrome, which leads to high blood pressure, hardening of the arteries and eventually heart attacks and strokes. The key today is to include in screening tests all parameters that will predict who is at risk to develop a heart attack or not.

Blood tests to screen for cardiovascular disease and inflammation

Blood tests and health history should be checked for dyslipidemia, high blood pressure (hypertension), hyperglycemia, smoking, diabetes, homocysteinemia, obesity etc. Also, patients with high GGTP (gamma-glutamyl transferase) levels in the blood are more at risk to develop diabetes. This in turn leads to inflammation of the arterial wall and heart attacks. There are 25 top risk factors that are associated with all causes for heart attacks.

Briefly, apart from the 7 factors already mentioned above the physician wants to check for high uric acid levels (hyperuricemia), kidney disease, high clotting factors (fibrinogen levels), elevated iron levels, trans fatty acid levels, omega-3 fatty acid levels and omega-6 to omega-3 ratio, low dietary potassium and magnesium intake with high sodium intake, increased high sensitivity C reactive protein level (hs CRP measuring inflammation). The list to test for cardiovascular disease risk continues with blood tests for vascular immune dysfunction and increased oxidative stress, lack of sleep, lack of exercise, subclinical low thyroid levels, hormonal imbalances for both genders, chronic infections, low vitamin D and K levels, high heavy metals and environmental pollutants.

The speaker stated that he includes a hormone profile and vitamin D levels. He does biochemical tests to check for mitochondrial defects. Micronutrients are also checked as cardiovascular patients often have many nutritional deficiencies. Inflammation is monitored through testing the levels of C-reactive protein (CRP).

In order to assess the risk of a patient Dr. Cohen, a cardiologist has developed the Rasmussen score, which is more accurate than the Framingham score.

The following tests are performed on the patient: computerized arterial pulse waveform analysis (medical imaging), blood pressure at rest and following exercise and left ventricular wall of the heart by echocardiography. Further tests include urine test for microalbuminuria, B-type natriuretic peptide (BNP, a measure of congestive heart failure), retinal score based on fundoscopy, intima-media thickness (IMT, measured by ultrasound on the carotid artery) and electrocardiogram recording (EKG).

Here is what the Rasmussen score means:

  • Disease score 0 to 2: likely no heart attack in the next 6 years
  • Disease score 3 to 5: 5% likely cardiovascular events in the next 6 years
  • Disease score > 6: 15% likely cardiovascular events in the next 6 years

Non-intervention tests to measure cardiovascular health

1. The ENDOPAT test

With this test the brachial artery is occluded with a blood pressure cuff for 5 minutes. Endothelial dysfunction is measured as increased signal amplitude. A pre- and post occlusion index is calculated based on flow-mediated dilatation. The values are interpreted as follows: an index of 1.67 has a sensitivity of 82% and specificity of 77% to predict coronary endothelial dysfunction correctly. It also correlates to a future risk for coronary heart disease, congestive heart disease and high blood pressure.

2. The VC Profile

This test measures the elasticity of the arteries. There is a C1 index that measures the elasticity of the medium and smaller vessels and the C1 index, which measures elasticity of the larger arteries and the aorta. The smaller the numbers are, the less elastic the arterial walls.

3.The Corus CAD score

This is a genetically based blood test. The score can be between 0 and 40. If the score is 40, there is a risk of 68% that there is a major blockage in one or more coronary arteries.

4. Coronary artery calcification

The CAC score correlates very well with major event like a heart attack. There is a risk of between 6- and 35-fold depending how high the CAC score is. The key is not to wait until you have calcification in your coronary arteries, but work on prevention.

Treatment of cardiovascular disease and inflammation

When heart disease is treated the doctor needs to address all of the underlying problems. It starts with good nutrition like a DASH diet or the Mediterranean diet.

Next anti-inflammatory and other supplements are added: curcumin 500 mg to 1000 mg twice a day, pomegranate juice ¼ cup twice per day, chelated magnesium 500 mg twice per day, aged garlic 1200 mg once daily, taurine 3 grams twice per day, CoQ-10 300 mg twice per day and D-ribose 5 grams three times per day. This type of supplementation helps for chest pain associated with angina. On top of this metabolic cardiology program the regular cardiac medicines are also used.

Additional supplements used in the metabolic cardiology program may be resveratrol 500 mg twice per day, quercetin 500 mg twice per day, omega-3 fatty acid 5 grams per day, vitamin K2 (MK 7) 100-500 micrograms per day and MK4 1000 micrograms per day. In addition he gives 1000 mg of vitamin C twice per day. This program helps in plaque stabilization and reversal and reduction of coronary artery calcification.

Case study showing the effect of metabolic cardiology program

Here is a case study of a heart patient that was treated by Dr. Houston. He was a white male, first treated for congestive heart failure as a result of a heart attack in June 2005. Initially his ejection fraction was 15-20%. His medications were: digoxin 0.25 mg once daily, metoprolol 50 mg twice per day, ramipril 10 mg twice per day, spironolactone 25 mg twice per day and torsemide 20 mg once daily. These medications were kept in place, but the metabolic cardiology program was applied in addition. Here are the results of his ejection fraction (EF) values after he was started on the metabolic program:

  • Initial measurement: EF15-20%. Marked shortness of breath on exertion.
  • 3 months: EF 20-25%. He reported improved symptoms.
  • 6 months: EF 25-30%. He said that he had now minimal symptoms.
  • 12 months: EF 40%. He had no more symptoms.
  • 24 months: EF 50%. He reported: “I feel normal and great”.
  • 5 years: EF 55%. He said” I feel the best in years”.

A normal value for an ejection fraction is 55% to 70%.

Cardiovascular Disease And Inflammation

Conclusion

Testing for heart disease risk has become a lot more sophisticated than in the past, and the tests have opened up a window to early intervention. Metabolic cardiology is a new faculty of cardiology that assists in the reversal and stabilization of heart disease. It will help high blood pressure patients and stabilizes diabetes, which would otherwise have deleterious effects on heart disease. Metabolic cardiology improves angina patients. It also prevents restenosis of stented coronary arteries. As shown in one clinical example reduced ejection fractions with congestive heart failure will improve. This was achieved solely through the metabolic cardiology program.

As usual, prevention is more powerful than conventional treatment later. To give your cardiac health a good start, don’t forget to cut out sugar, exercise regularly and follow a sensible diet.

How To Avoid Being Hungry

Dr. Ludwig gave a lecture about how to avoid being hungry at a conference in Las Vegas. The actual topic was “Always Hungry?” I attended the 24th Annual World Congress on Anti-Aging Medicine (Dec. 9-11, 2016) in Las Vegas where this lecture was given. Dr. Ludwig is a Harvard-based endocrinologist who has been researching weight loss methods and obesity for over 20 years. Here is a list of his major publications.

Dr. Ludwig stated that the low fat/high carb diet popular in the1980’s until the early 2000’s was misguided and probably even harmful. The theory at that time was that obesity was caused by too much saturated fat. This has since been proven to be wrong. Instead it has been proven that increased sugar intake is responsible for the obesity wave.

General information about weight gain

The carbohydrate-insulin model states that without insulin you cannot gain weight, because in order to store fat in fatty tissue you need insulin to transport fatty acids across the cell membrane of fat cells.

In this context it is important to note that high glycemic index food increases the blood sugar. This leads to stimulated insulin production, and the liver converts the extra sugar into fatty acids that get deposited as fat in fatty tissue.

The glycemic load from a person’s diet is the single best predictor for a rising blood sugar level. After food intake the blood sugar goes up, glucagon goes up, epinephrine goes up within 4 hours. It is the epinephrine, which after 4 hours makes you hungry again.

The nucleus accumbens is the addiction center. At 4 hours after a high glycemic index milk shake the nucleus accumbens was stimulated in 12 subjects of a double blind trial.

The nucleus accumbens does not work in isolation. It is not only involved in food satisfaction, but also in sexual satisfaction and even plays a role in satisfaction that some people get from playing video games.

Low-carbohydrate, Mediterranean or low-fat diet

In an Israeli study from the New England Journal of Medicine in 2008 investigators were interested to find out which diet was helping people to lose most weight. h

322 moderately obese subjects that were aged 52 years on average were randomized to one of the following diet groups.

They compared

  1. a low fat diet (Atkins type, restricted calorie) with a
  2. Mediterranean diet (low carb, restricted-calorie) and a
  3. Low fat/high carb diet (low fat, non-restricted-calorie)

What was the result? The mean weight losses were: 2.9 kg (low fat group), 4.4 kg (Mediterranean diet group), and 4.7 kg (low fat/high carb group). Of the 272 participants who had completed the intervention after two years of the study the weight loss was 3.3 kg, 4.6 kg, and 5.5 kg in the same sequence as above.

The ratio of total cholesterol to high-density lipoprotein cholesterol, which is a measure for the heart attack risk, was examined next. It was 20% lower from the baseline in group 2 (Mediterranean diet group). The low fat groups (group 1 and 3) were 12% lower from the baseline.

36 subjects had diabetes. There was a clear winner with respect to lower fasting blood sugar and insulin levels, namely the Mediterranean diet (group 2).

The authors concluded that the Mediterranean diet is preferable to low fat diets as they have shown an improvement in lipid profiles and in control of diabetes.

The “POUNDS LOST” study

This was a 2-year study that investigated 4 different lower calorie diets to help people lose weight. Despite the significant difference in diet composition, these 811 free-living overweight or obese adults ages 30-70 from Boston, MA and Baton Rouge, LA lost 16 pounds at 6 months and 9 pounds at the end of two years. The diets were 1) low fat (20%) or 2) high fat (40%) 3) average protein (15%) or 4) high protein (25% of total calories).

The authors concluded that any reduced, calorie-controlled diet would help obese or overweight people to achieve weight loss that lasts. It is interesting that it did not matter whether the diet was low or high in fat, or had low or high protein content. What did matter was that all diets were low in sugar.

Sugar is the driving force

Dr. Ludwig pointed out that without insulin you couldn’t gain weight. High glycemic index food increases blood sugar. The glycemic load is the single best predictor to indicate whether a person will gain weight or lose weight when this food is consumed. It is an irony that in the 1980’s and 1990’s the obesity wave was created by the wrong assumption that a low fat/high carb diet would be heart healthy. We have abundant data available that show otherwise: high sugar content of food brings the calorie count up as everybody can read on the food labels.This will lead to weight increase, which has been abundantly proven. Sugar also stimulates your nucleus accumbens, the food addiction center. As you probably know it is extremely difficult to get out of this food addiction cycle unless you cut out sugar. You even need to go one step further and include many starchy foods that will within 30 minutes of digesting them turn into sugar. Your system makes no difference whether you eat a few teaspoons of sugar or two slices of white bread. The response of your pancreas is insulin, which gladly stores the fatty substances your liver made as fat.

How to get out of the vicious food cycle

As the quoted publications and many other ones have shown, it only matters that you limit your refined carb intake. You can vary the fat content and you can vary the protein content and still lose weight provided you watch the low carb intake. You also need portion control, which is a given! Study glycemic index and glycemic load sites on the Internet. The links I provided are just some examples. The more you educate yourself about carbs, the better for you. Note that many fruit and vegetables belong to the low-glycemic load/index foods. Avoid the high glycemic index foods like dates and cornflakes. Stick to low-glycemic index foods, which are less than 55. With regard to low-glycemic load food the values should be below 10.

The Mediterranean diet is a very desirable diet, which has been proven to be anti-inflammatory.

The zone diet of Barry Sears is also an anti-inflammatory diet and he summarizes this in this link.

How To Avoid Being Hungry

How To Avoid Being Hungry

Conclusion

I have summarized the content of a talk given by Dr. Ludwig. We learnt from this that sugar and refined carbs are the driving force that leads to “feeling hungry”. This stimulates your nucleus accumbens, the food addiction center. Let’s assume that a person is obese or overweight and wants to lose some weight. You need to start by being strict with yourself. Cut out sugar and high-glycemic foods. This will remove the food addiction factor that keeps you going back to the wrong, high calorie foods. You will also consume more low calorie vegetables and fruit, which have more fiber that fills you up. Once you are used to the new way of eating, there is no need to count calories. I recommend that you weigh yourself daily on body composition scales and record the results. This allows you to monitor your body mass index (BMI), your weight, your fat percentage, and your muscle percentage. Typically you will lose 2 to 3 pounds per week on such a low-calorie diet. Later the weight loss will slow down to 1 to 2 weeks per week until you reach your goal. Don’t go lower than a BMI of 21.0 to 22.0 and discuss your goal with your doctor.

Magnesium Is Essential To Life

Magnesium is an important co-factor in many biochemical reactions, so magnesium is essential to life.

Many diverse diseases and cancers can develop from magnesium deficiency. The key is to supplement with magnesium regularly to get more than the government recommended daily allowance (RDA). The RDA for magnesium is 420 mg a day for males and 320 mg a day for females.

In the following I will review the diseases that occur without enough magnesium on board.

A lack of magnesium can cause heart disease

In this 2014 study 7216 men and women aged 55-80 with at high risk for heart attacks were followed for 4.8 years. The risk of death from a heart attack was found to be 34% lower in the high tertile magnesium group when compared to the lower magnesium tertile group.

The protective mechanism of magnesium was found to be as follows. Magnesium counteracts calcium and stabilizes heart rhythms. Magnesium helps to maintain regular heart beats and prevents irregular heart beats (arrhythmias). It also prevents the accumulation of calcium in the coronary artery walls. This in turn is known to lower the risk of heart attacks and strokes.

Another study, which was part of the Framingham Heart Study, examined calcification of the heart vessels and the aorta as a function of magnesium intake.

There were 2,695 participants in this study. For each increase of 50 mg of magnesium per day there was a 22% decrease in calcification of the coronary arteries. For the same increase of magnesium the calcification of the body’s main artery, the aorta, fell by 12%. Those with the highest magnesium intake were 58% less likely to have calcifications in their coronary arteries. At the same time they were 34% less likely to have calcifications of the aorta.

In a Korean study a group with low magnesium levels was at a 2.1-fold higher risk of developing coronary artery calcifications compared to a group with normal magnesium levels.

Low magnesium increases your stroke risk

In a 2015 study 4443 subjects, men and women aged 40-75 were followed along.

928 stroke cases developed. The group with the highest 30% of magnesium intake was compared with the lowest 10% of magnesium intake. They had significantly lower blood pressure (7 mm mercury) and lower total cholesterol levels. They also had 41% less strokes than those with low magnesium intake.

In a 2015 study that lasted 24 years the authors investigated 43,000 men.

Those with the highest magnesium supplement had a 26% lower stroke risk. They had been compared to those with the lowest magnesium intake.

Among women low magnesium levels were shown to cause 34% more ischemic strokes than in controls.

This study was from 32,826 participants in the Nurses’ Health Study who were followed for 11 years.

It is clear from all these studies that supplementation with magnesium can prevent strokes.

Magnesium protects kidney function

This study examined 13,000 adults for 20 years to see how kidney function was dependent on magnesium levels. Those with the lowest magnesium levels had a 58% higher risk of developing chronic kidney disease. It makes sense when you consider that magnesium is needed to keep arteries healthy, blood pressure low, and blood sugars stable. In diabetics where blood sugar is not controlled kidneys develop kidney disease. This is called diabetic nephropathy. In the presence of magnesium supplementation and a low sugar diet people are less likely to develop diabetes or kidney disease.

Magnesium helps blood sugar control

A metaanalysis showed that magnesium supplementation was able to improve blood sugar control. This occurred in both diabetics and borderline non-diabetics within 4 months of supplementing with magnesium.

Magnesium has been known in the popular press to be an important factor in helping control blood sugar. Here is an article as an example.

Magnesium good for bones and teeth

Magnesium is important for calcium metabolism and this is helping your bones and teeth to stay strong. About half of the body’s magnesium is stored in bone. Teeth are the other location where a lot of magnesium is found.

Low levels of magnesium lead to osteoporosis, because one of the two structural components of bone (calcium and magnesium) is missing. In addition low magnesium causes inflammatory cytokines to increase. These break down bones. The Women’s Health Initiative showed that when daily magnesium intake exceeded 422.5 mg their hip and whole-body bone mineral density was significantly greater than in those who consumed less than 206.6 mg daily.

With regard to healthy teeth magnesium is important as it prevents periodontal disease.

This study found that there was less tooth loss and there were healthier periodontal tissues in 4290 subjects between 20 and 80.

Those who took magnesium supplements had healthier teeth.

Migraine sufferers improve with magnesium

A double blind randomized study showed that magnesium supplementation can reduce migraines. In this trial 600 mg of magnesium supplementation was used for 4 weeks.

This reduced migraines by 41.6% in the magnesium group compared to the non-supplemented control group.

Another study showed that both intravenous and oral magnesium are effective in reducing migraine headaches.

Intravenous magnesium showed effects on improving migraines within 15 – 45 minutes. The authors concluded that both oral and intravenous magnesium could be added as a supplement to other migraine treatments.

Cancer can be caused from too little magnesium

You may be surprised to hear that magnesium can even prevent some cancers. Two cancers have been studied in detail. I will limit my discussion to these two.

Pancreatic cancer

One study found that pancreatic cancer was reduced. 142,203 men and 334,999 women, recruited between 1992 and 2000, were included. After 11.3 years on average 396 men and 469 women came down with pancreatic cancer. On the male side they found that when the body mass index (BMI) was greater than 25.0 there was a 21% reduction of pancreatic cancer for every 100 mg of added magnesium per day. There were a lot of smokers on the female side, which interfered with the study as confounding factors undermined statistical validity.

In another study, the US male Health Professionals Follow-up Study was examined after 20 years of follow-up. Those with a BMI of above 25.0 on magnesium supplementation had a reduced risk of pancreatic cancer. The pancreatic cancer rate in the higher magnesium group was 33% lower than in the lower magnesium group. The higher group consumed 423 mg of magnesium daily, the lower group 281 mg per day. It is significant that in both studies it was the heavier patients who came down with pancreatic cancer. It is known that obesity is a pancreatic risk factor.

Colorectal cancer

A study done on Japanese men showed that magnesium could protect them significantly from colon cancer.

Men who consumed the highest amount of magnesium developed 52% less colon cancer over 7.9 years. They were compared to the group with the lowest 20% intake of magnesium. The women in this study did not reach statistical significance.

A study from the Netherlands examined colon cancer in patients. They found that only in patients with a BMI of greater than 25.0 magnesium did have protective effects. For every 100 mg of magnesium per day increase there was a 19% reduction of colon polyps. And there was also a 12% reduction of colorectal cancer for every 100 mg increase of magnesium per day.

Magnesium plays an important role in genome stability, DNA maintenance and repair. It also prevents chronic inflammation and reduces insulin resistance, all factors contributing to cancer reduction.

Live longer with magnesium

Consider that magnesium is the fourth most common mineral in the body. Add to this that magnesium is a co-factor of more than 300 enzymes in the body. Magnesium is required as an important co-factor in the conversion of chemical energy from food that we ingest. Magnesium is regulating blood sugar, blood vessel health and our brain electrical activity. 50% of our stored magnesium can be found in our bones, which helps the strength and integrity of them.

Because of the distribution of the enzymes that are helped by magnesium to function properly, virtually every cell in the body depends on our regular intake of magnesium.

Since the 1950’s soils are depleted of magnesium where vegetables are grown and fruit trees are raised. We simply do not get enough magnesium from food.

But chelated magnesium is freely available in health food stores. Take 250 mg twice per day, and you will have enough.

Because our metabolism slows down, there is a critical age where magnesium deficiency becomes more obvious than when we are younger. By the age of 70 there are 80% of men and 70% of women who do not get the minimum of magnesium-required amount they should get (350 mg for men and 265 mg for women).

At this age many people are on multiple drugs. For many proton pump inhibitors (PPI) are used to suppress acid production in the stomach. PPI’s have been associated with low magnesium blood levels.

This link explains that PPI’s should not be used for longer than 1 year.

Low magnesium levels accelerate the aging process on a cellular level. Low magnesium levels increase senescent cells that can no longer multiply. Some of them could cause the development of cancer. These senescent cells also can no longer contribute to the immune system. This causes more infections with an adverse outcome.

Remember to take chelated magnesium capsules or tablets 250 mg twice per day and you will be protected from low magnesium levels in your body.

Here is why we live longer with magnesium supplementation

Our blood vessels will not calcify as early; they keep elastic for longer, preventing high blood pressure. Our kidneys will function longer with magnesium, preventing end-stage kidney disease. We need our kidneys to detoxify our system! The more than 300 enzymatic reactions all over our body help that we have more energy and that cancer is prevented. When there are fewer strokes and less heart attacks this helps reduce mortality. It also helps that there is less of a risk for Alzheimer’s disease with magnesium supplementation, because insulin resistance is reduced, which has been shown to prevent Alzheimer’s disease.

The bottom line is we live longer and healthier; that is what is meant with longevity.

Magnesium Is Essential To Life

Magnesium Is Essential To Life

Conclusion

Magnesium is a key essential mineral. It balances calcium in the body and participates in many enzymatic reactions in the body as a cofactor. As long as we have enough of this mineral we won’t notice anything. It is with magnesium deficiency that things go haywire. You could get heart disease or a stroke. You could get kidney disease. You even could get pancreatic cancer or colorectal cancer. If this is not enough, magnesium deficiency can cause diabetes, osteoporosis and bad teeth. You may suddenly die with no obvious cause. But, if your magnesium blood level is balanced from regular supplements, you will carry on living and eliminate a lot of health problems.

Stress Drives Our Lives

Every year the American Psychological Association (APA) monitors the American public how stress drives our lives. This yearly report has been compiled since 2007. About 75% of the people questioned reported that they have experienced moderate to high stress over the past month.

Symptoms when stress drives our lives

What kind of symptoms can stress cause? It can cause sleep deprivation, anxiety, headaches and depression. But there can be more symptoms from any disease that stress may cause. The “Stress in America” report from February 2016 shows on page 5 that unhealthy life habits are used by low-income Americans to cope with stress. A bar graph shows that watching television or movies for more than 2 hours per day is common. Another way of coping is to surf the Internet more often, take more naps or sleep longer. Eating more, drinking alcoholic beverages and smoking more are other unhealthy ways to cope with stress.

As the stressed person gains extra weight and eventually becomes obese, there is a higher rate of diabetes that can develop with all of its complications.

Causes of stress in our lives

The “Stress in America” survey was based on 3,068 adults in the US who completed the survey during August 2015. 72% were stressed out about financial issues. 22% of these said that they were extremely stressed in the past month as a result of money concerns. Other common concerns were work, the economy, family responsibilities and concerns about personal health. Average stress levels among Americans decreased when compared to 2007. On a 10-point stress score respondents rated their stress at 4.9 in 2016 compared to 6.2 in 2007. But according to the American Psychological Association this is much higher than a stress rating of 3.7 considered to be a healthy level.

Stress affects people from all walks of life, workers, women, young adults, students and those with lower incomes.

“Stress is caused by the loss or threat of loss of the personal, social and material resources that are primary to us” Stevan Hobfoll, PhD, a clinical psychologist from Rush University Medical Center said. “So, threat to self, threat to self-esteem, threat to income, threat to employment and threat to our family or our health…” is what causes stress.

Stress drives our lives causing disease

When stress is too much for our system, we are starting to see pathology develop. “Stress is seldom the root cause of disease, but rather interacts with our genetics and our state of our bodies in ways that accelerate disease” professor Hobfoll says. The following are common diseases that can result from chronic stress.

Heart attacks and strokes

In a 2015 Lancet study 603,838 men and women who worked long hours were followed for a mean of about 8 years with respect to heart disease or strokes. All of the subjects were free of heart attacks and strokes when they entered into the study. There were a total of 13% more heart attacks in those who worked extra hours compared to those who worked 40 hours per week or less. With respect to strokes there were 33% more strokes in those who worked long hours. A dose-response association was calculated for strokes in groups with various workloads. Compared to standard working hours there were 10% additional strokes for 41-48 working hours, 27% for 49-54 working hours and 33% for 55 or more working hours per week.

Stress drives our lives and causes substance abuse

In order to cope with stress many of us treat daily stress with alcohol. It makes you feel good subjectively, but it can raise your blood pressure causing heart attacks and strokes down the road. A low dose of alcohol may be healthy, but medium and high doses are detrimental to your health.

Next many people still smoke, which has been proven long time ago to be bad for your health. It can cause heart attacks, various cancers and circulatory problems leading to leg amputations.

Overeating is another common problem. As comfort food relieves stress, extra pounds are put on. As you know it is easier to put weight on than get it off. Being overweight or being obese has its own problems: arthritis in the hips and knees makes walking more difficult. The metabolic syndrome sets in, which is a characteristic metabolic change causing diabetes, high blood pressure, heart attacks, strokes and certain cancers. The more weight you carry, the less likely you are to exercise. This deteriorates your health outlook.

Diabetes

Stress causes too much cortisol secretion from the adrenal glands. This raises blood sugar, and when chronic can cause diabetes. In addition unhealthy eating habits associated with stress can cause weight gain and high blood sugars leading to diabetes.

In a 2012 California study 148 adult Korean immigrants were examined. They all had elevated blood sugars confirming the diagnosis of type 2 diabetes. Their waist/hip ratio was elevated.

A high percentage of the study subjects had risk factors for type 2 diabetes. This included being overweight or obese and having high blood glucose readings. 66% of them said that they were feeling stressed, 51% reported feeling anxious, 38% said they were feeling restless, 30% felt nervous and 3% said they were feeling hopeless.

An Australian long-term follow-up study computed risk factors for developing type 2 diabetes. Stress was a major contributor to diabetes.

Diabetes was significantly associated with a 30-day episode of any anxiety disorder with a 1.53-fold risk. A depressive disorder had a 1.37-fold risk to cause diabetes and posttraumatic stress disorder had a risk of 1.42-fold to cause diabetes.

Infertility

Stress changes hormones in women causing ovulation problems and infertility. 1 in 8 couples in America have problems getting pregnant. Stress has been identified as being at least a contributing factor. But in men stress can also reduce sperm count and semen quality as this study describes.

Alzheimer’s disease

A 2010 study from Gothenburg University, Sweden examined 1462 woman aged 38-60 and followed them for 35 years.

Psychological stress was rated in 1968,1974 and 1980. 161 females developed dementia (105 Alzheimer’s disease, 40 vascular dementia and 16 other dementias). The risk of dementia was reported higher in those women who had frequent/constant stress in the past and was more severe the more stress they were exposed to in the past. Women who were exposed to stress on one, two or three examinations were observed to have higher dementia rates later in life, when compared to women who were not exposed to any significant stress. Specifically, dementia rates were 10% higher when exposed to one stressful episode, 73% higher after two stressful episodes and 151% higher when exposed to three stressful episodes.

Remedies for stress

Before you can attempt to remedy stress, you must first detect that you are under stress. You can recognize this when you have problems sleeping, you suffer from fatigue, when overeating or undereating is a problem, and if you feel depressed. Others may feel angry or are irritable. Some bad lifestyle habits may also make you aware that you are under stress. You may smoke or drink more in an attempt to manage stress. Some people abuse drugs.

Here are some suggestions how to remedy stress:

  1. Seek support from family, friends or religious organizations. If you engage in drugs or alcohol overuse or you feel suicidal, it is best to seek the advice from a psychiatrist or psychologist.
  2. Engage in regular exercise. This produces endorphins, the natural “feel-good” brain hormone. This reduces symptoms of depression and improves sleep quality.
  3. Do something that increases pleasure, such as having a meal with friends, starting a hobby or watching a good movie.
  4. Positive self-talk: avoid negative thoughts like “I can’t do this”. Instead say to yourself “I will do the best I can”. Psychologists have developed a technique where they teach patients how to turn negatives into positives. It is called “cognitive therapy”. You may want to seek the advice of a psychologist to have a few cognitive therapy sessions.
  5. Daily relaxation: you may want to use self-hypnosis, tai-chi exercises or meditation to reduce your stress levels.
Stress Drives Our Lives

Stress Drives Our Lives

Conclusion

Stress is very common. Diverse diseases like heart attacks, strokes, diabetes and Alzheimer’s disease can all be caused by stress. It is important to minimize the impact of stress by seeking family support and support from friends. Engaging in regular exercise will release endorphins and make you feel better. Relaxation exercises and seeking counselling can all help you to manage stress. It is not a force in your life that can be ignored or simply tolerated. Stress is indeed there, but we can make a difference by managing it to avoid that stress manages us.

Arthritis Drugs Can Cause Heart Failure

The British Medical Journal has published a research articles in Sept. 2016 showing that arthritis drugs can cause heart failure. This occurs particularly in elderly patients around the age of 77 years and older. This is an age where arthritis is often causing pain, and the pain is regulated with over-the-counter pills. These anti-arthritis drugs belong into the group of anti-inflammatory drugs, called NSAIDs. This stands for “non-steroidal anti-inflammatory drugs”. The study was entitled “Non-steroidal anti-inflammatory drugs and risk of heart failure in four European countries…”

Arthritis drugs can cause heart failure shows study

Adult patients above the age of 18 who started 27 different types of NSAIDs between 2000 and 2010 were followed. 92,163 hospital admissions for heart failure were noted; 8,246,403 patients who were not taking NSAIDS served as controls. There were 4 countries involved in this study providing 2.2 million patients from the Netherlands, 7.5 million from Italy, 13.7 million from Germany and 11.1 million from the United Kingdom.

Results of study

NSAID use of up to 2 weeks prior to assessment had a risk of 19% of resulting in a hospital admission for heart failure. A control group of patients who had not taken NSAIDs for at least 6 months or more had no hospital admission risk.

Seven traditional NSAIDs were found to be associated with hospital admission for heart failure. They were: diclofenac (brand name Voltaren), ibuprofen (brand name Motrin), indomethacin (brand name Indocin), ketorolac (brand name Toradol), naproxen (brand name Naprosyn or Aleve), nimesulide (brand name Mesulid and many others), and piroxicam (brand name Feldene). In addition two COX 2 inhibitors, etoricoxib (brand name Arcoxia) and rofecoxib (brand name VIOXX) were also having the same side effects.

  1. The risk for heart failure was not the same for every NSAID. The risks ranged from 1.16-fold to 1.83-fold. Specifically ketorolac had a risk of 1.83-fold, indomethacin 1.51-fold, piroxicam 1.27-fold, diclofenac 1.19-fold, ibuprofen 1.18-fold, and naproxen 1.16-fold. Translated into common language it means that ketorolac had a risk of 83% of causing a hospital admission due to heart failure. In the case of ibuprofen it was only an 18% risk.
  2. The risk for heart failure doubled for diclofenac, etoricoxib, indomethacin, piroxicam, and rofecoxib when used at very high doses. Doubling the risk means a 200% risk. Typically, when an arthritis patient has a flare-up of pain, this is the time when the NSAIDs are usually taken at a higher dose and tend to also be taken for a longer time. Some NSAIDs had a significant risk for heart failure even at a medium dose. This was the case for indomethacin and etoricoxib. The good news was that celecoxib (brand names Celebrex and Celebra) at usual doses did not lead to an increased risk of heart failure.
  3. Dose-response curves were obtained where possible. Here the researchers looked at the effect of low, medium, high and very high doses of NSAIDs in patients. Again heart failure occurrence was studied among those patients. The result clearly showed that low and medium doses of NSAIDs were fairly safe, but high and very high doses of NSAIDs caused heart failure. Etoricoxib, Piroxicam and Rofecoxib were particularly toxic in higher doses. Indomethacin was toxic at medium and high doses. An important exception to the rule was celecoxib (brand names Celebrex and Celebra), which did not cause heart failure, either at low doses or high doses. This is one of the most used NSAIDs, so it is fortunate that it does not cause heart failure.

Discussion of study

The authors of this study discussed why they believe heart failure is developing in patients who take NSAIDs. They argued that NSAIDs inhibit prostaglandin synthesis and the enzymes COX1 and COX2. This is how inflammation and pain gets inhibited, which is a good thing. But at the same time blood supply to the kidneys is reduced, kidney function is impaired, and sodium is retained. This is a bad thing as it leads to fluid retention and fluid overload of the heart resulting in heart failure. As the prostaglandin inhibition is dose-dependent, the authors said this is the reason that the heart failure rate is also dose-dependent when measured in large populations, as was done in this study. A noted exception, as already mentioned, is the popular celecoxib, which does not cause heart failure, even at high and very high doses.

Arthritis Drugs Can Cause Heart Failure

Arthritis Drugs Can Cause Heart Failure

Conclusion

This publication has a lot of statistical power as it was based on research in 4 European countries and involved almost 10 million subjects that were compared to an equally large control population. Because of the size of the study population it was possible to calculate risk ratios for NSAIDs causing heart failure for 27 different types of NSAIDs. Furthermore, the authors succeeded in quite a few cases to calculate risk factors for different concentrations of NSAIDs used. This statistical method is called a dose-response curve. It is a powerful pointer to toxicity when high doses cause heart failure, but low doses don’t.

The physician can use the information from this publication to select one of the NSAIDs that is least harmful, like celecoxib (brand names Celebrex and Celebra) and tell the patient to use the least amount possible to minimize side-effects. Many aging arthritis sufferers will benefit from this. Hopefully the FDA will review this material and shut down the use of some of the more dangerous NSAIDs or force the manufacturer to attach a black box warning about the drugs that belong into this category. You should review what your favorite NSAID is and discuss this with your physician. Perhaps print a copy of this review and take it with you, in case your health provider has not heard about it yet.

New FDA Food Guidelines

A recent news release describes 2016 new FDA food guidelines. In it double the amount of seafood (fish and shellfish) is recommended as well as a cut in saturated fat and in sugar. Coffee, which was labeled a culprit in the past is now recommended to a total of 400 mg of caffeine per day as it is heart protective. Cholesterol is no longer considered an enemy, but sugar, saturated fats and trans fats are.

Here is a breakdown of what each of these recommendations means.

New FDA food guidelines regarding increasing fish and shellfish

The anti-inflammatory effects of omega-3 fatty acids have finally entered the recommended diet plan of the FDA. This reflects the nutritional research over the last few decades that noticed a longer life expectancy for people who eat more seafood and less red meat.

The only problem with seafood can be its mercury contamination. The higher predator fish are in the food chain, the more contaminated fish meat is. This is the reason that tuna fish is not recommended as a food source, as it is very high in mercury. An exception is canned tuna as it has been washed and some of the mercury got lost in the food processing. Wild salmon, sardines and oysters are low in mercury and good sources of omega-3 oils.

New FDA food guidelines regarding reduction of saturated fat

It is now recommended that saturated fat should be reduced to 10% of the total daily caloric intake. This is not undisputed as some studies show that saturated fat may not be involved in the production of hardening of the arteries. Other studies have shown that breast cancer is more common when more saturated fat is consumed.

When the news came out in the 1980’s that saturated fats would be bad for arteries, there was a switch to polyunsaturated acids: safflower oil, canola oil, sunflower seed oil, corn oil and soybean oil or grapeseed oil.

However, the irony is that these vegetable oils were highly unstable and led to oxidation causing heart disease and cancer.

In contrast olive oil is a much more stable oil and has been associated with longer lives in the Mediterranean. Similarly, coconut oil is also more stable and is recommended for cooking as well.

New FDA food guidelines regarding protective effect of coffee

In the past few years many studies have shown the coffee consumption prolongs life. The FDA has now officially recognized these studies and recommends that consumption of up to 400 mg caffeine will help promote health. On the other hand the FDA also recommends that those who do not drink coffee, should not change their lifestyle just because of these recommendations.

New FDA food guidelines regarding sugar reduction

An entirely new recommendation of the FDA is that sugar should be reduced in anybody’s diet. The FDA explains that sugar is contained in too many processed foods, is added in drinks like coffee, fruit juices, food items like muffins and cakes.

In the past decades it has become clear that sugar much more so than fat is the culprit, when it comes to hardening of arteries. Sugar gets metabolized in the liver, triglycerides and LDL cholesterol are increased and this gets deposited into arteries and fatty tissue. In this context it makes sense that the FDA now recommends a reduction of sugar intake.

 New FDA food guidelines regarding cholesterol

In the past it was thought that cholesterol in meat would be the cause of high cholesterol in the blood. This was an oversimplification. We now know that only a small portion of the blood cholesterol comes from food sources, so that cholesterol from food sources is now no longer thought to be of importance with regard to risks for heart attacks and strokes. Instead it is sugar and too many starchy foods (Bread, pasta, pizza, muffins, cakes cookies) that get broken down into sugar, which accounts for high cholesterol by being metabolized in the liver into LDL cholesterol and triglycerides.

New FDA Food Guidelines

New FDA Food Guidelines

Conclusion

The new food guide by the FDA has fundamentally changed the previous recommendations based on newer nutritional studies. Now fish and shellfish should be doubled compared to previous recommendations. Coffee is no longer the enemy, but your friend. Sugar and starch over consumption is to be avoided, as this can raise cholesterol and triglyceride levels. Eat more vegetables and fruit. These recommendations closely resemble a Mediterranean diet, which has been shown to prolong life in several studies. Abandon the American Standard diet with hamburgers, processed foods and sugary drinks. Pay attention to the FDA food recommendations!

Avoid That Heart Attack

Recently Dr. Mark Hyman mentioned a 7-point program to avoid that heart attack. If you follow the recommendations below, chances are that you do not only avoid heart attacks, but also strokes, high blood pressure, diabetes and obesity.

The Potsdam (or EPIC) study has shown that adhering to 4 simple things can reduce

Diabetes by 93%

Heart attacks by 81%

Strokes by 50%

All cancers by 36%.

What were those 4 points?

  1. Not smoking
  2. Exercising 3.5 hours a week
  3. Eating a healthy diet
  4. And maintaining a healthy weight

So with a few more points added it is no wonder that the figures can be even more impressive.

Other studies have also shown the importance of lifestyle changes to improve health outcomes; the INTERHEART study was based on 30,000 people in 52 countries that were followed along. Researchers found that 90 percent of all heart disease could be prevented by simple lifestyle changes.  I have added another point, regular exercise that has been proven to be very effective in preventing many diseases.

So, what are the 8 points that can assure that our health improves?

  1. Avoid that heart attack with a colorful, plant-based diet

Your dietary intake is important, because it provides all of the building blocks for your body. You want whole foods that are rich in phytonutrients. Often rainbow colors are mentioned, because the more varied your vegetables look, the more balanced the micronutrients, vitamins and minerals in the food items. Below we will learn that we want to avoid processed foods and hydrogenated fats, but we want to increase fiber and omega-3 fatty acids.

  1. Avoid that heart attack by stabilizing your blood sugar

Never eat refined carbs alone, as this goes chases up your blood sugar levels and causes unhealthy insulin reactions. Too much insulin production causes inflammation in the body, which can cause inflammatory bowel disease, arthritis, clogged arteries with heart attacks and strokes and Alzheimer’s disease. You want to balance complex carbs from vegetables with healthy fats and clean protein in every meal. Avoid sugars- no matter whether it is “natural brown” or white sugar and refined carbohydrates. Your pancreas does not differentiate between honey and other sugars, and it will react the same way!

  1. Avoid that heart attack by increasing fiber intake

The more fiber you can tolerate, the better. 50 grams would be ideal, but not everybody can tolerate this due to bloating or a queasy stomach. But even if you can add 5 or 10 grams of fiber per day, this is progress. Fiber decreases LDL cholesterol by intervening with the enterohepatic pathway. Fiber is found in nuts, beans, vegetables, seeds and berries that have lower sugar in them. You can also take a fiber supplement directly like psyllium husk.

  1. Avoid that heart attack by cutting out processed foods

Processed foods and junk foods are popular as they fill you up fast when you are hungry. But they need to be avoided at all costs. Sodas, juices and diet drinks affect your sugar and fat metabolism. The extra calories that come from sugary drinks are the biggest contributors to diabetes, heart disease and obesity. Even 100% fruit juice is not healthy, because all of the fiber is removed and you are drinking sugar water to which your pancreas reacts by producing extra insulin. As already discussed the extra insulin just causes inflammation. May I suggest a homemade lemon juice that you make by squeezing ½ lemon into a glass; add a tiny bit of Stevia for sweetening and sparkling mineral water. This is a healthy drink without sugar. You can drink this as often as you want. Another component of processed food are omega-6 fatty acids. They are in processed foods, because they increase the shelf life in stores. But they cause inflammation in the body unless balanced by omega-3 fatty acids (see below).

  1. Avoid that heart attack by increasing omega-3 fatty acids

Fish and seafood provide you with healthy omega-3 fatty acids. Unfortunately not all fish are healthy. Tuna is a predator fish that accumulates a lot of mercury from the polluted oceans. As a result of this it is not on my fish list. I prefer wild salmon. I also take molecularly distilled fish oil, which has omega-3 fatty acids in it. Many processed foods contain only omega-6 fatty acids, because this is the cheapest way to produce them (they are based on vegetable oils). Also avoid soybean oil, which is the most popular oil in the last few decades to foul up the omega-6 to omega-3 ratio. This ratio should be 1:1 to 3:1, but many Americans’ omega-6 to omega-3 ratio is 6:1 to 18:1. Omega-6-fatty acids cause arthritis, heart disease and strokes. Instead you want to eat healthy fats like omega-3 fatty acids contained in nuts and fish. You can also add molecularly distilled, high potency omega-3 fatty acids as a supplement to help restore the balance between omega-6 and omega-3 in your food intake.

  1. Avoid that heart attack by eliminating all hydrogenated fat

Hydrogenated fat like margarine has been shown to cause accelerated hardening of the arteries, which causes heart attacks and strokes. Read labels and eliminate any food that contains hydrogenated fats. If the label indicates that you are dealing with a product containing ”partially hydrogenated oil”, stay away from it as well! Butter from grass fed cows is a healthy fat. Olive oil and coconut oil are both good cooking oils. Olive oil is also good in salad dressings.

  1. Avoid that heart attack by keeping alcohol to a minimum

The problem with alcohol is that it is a cell poison. On the other hand small amounts have been show to reduce heart attacks and strokes (one glass for women, two glasses for men per day). However, due to the cell poison effect even low amounts of alcohol contribute to cancer causation, and as a result of that alcohol remains a problem. If you must consume alcohol limiting the intake to minimal amounts is prudent. In women ovarian cancer can be caused by alcohol and men prostate cancer. In both sexes pancreatic cancer can be caused by alcohol. Higher amounts of alcohol raise inflammation with elevation of blood pressure, heart attacks and strokes. One recommendation: either consume no alcohol or use alcohol in moderation. One glass does not kill you, but several ones may do it over time!

  1. Avoid that heart attack by exercising regularly

Regular exercise is yet another factor that can help you to reduce heart attacks, strokes and cancer even further. I added it as point 8, because it is fundamentally such an important preventative factor. Some studies have shown as much as a 50% drop in many diseases simply by introducing regular exercise.

Avoid That Heart Attack

Avoid That Heart Attack

Conclusion

It is all about lifestyle factors. Pay attention to your diet. Add fiber, subtract sugar. Avoid processed foods, omega-6 fatty acids and hydrogenated fat. Have enough omega-3 fatty acids as fish and supplements. Keep alcohol to a minimum. Your benefits from changing these lifestyle factors, result in huge benefits. You are avoiding 90% of diabetes, 80% of heart attacks, 50% of strokes and 35% of cancers.

Prevent Unhealthy Aging

We know that stress can age you prematurely, but what do we need to do to prevent unhealthy aging? This is exactly what this review by cardiologist Dr. Joel Kahn has done. It points out that the right lifestyle makes the difference.

Studies showing how to prevent unhealthy aging

Several studies have shown how to avoid getting heart disease, cancer and diabetes.

  1. Kahn reported that in 2001 the Harvard School of Public Health published a study where 84,941 healthy female nurses had been followed who were free of heart disease, cancer and diabetes at baseline. But only 3.4% of the 84,941 women managed to stay healthy after 16 years of the study. The secret? Their body mass index (BMI) was less than 25.0, their diet was high in polyunsaturated fat and fiber, low in trans fat and low in glycemic load, they engaged in regular moderate exercise with a minimum of 30 minutes per day; they did not smoke and they drank ½ an alcoholic drink per day. Their risk to get diabetes was 91% lower than the rest of the study. This shows you how powerful lifestyle choices are.
  2. In 2004 an international study (the INTERHEART study) reported in the Lancet the lifestyle of 15,152 cases that developed heart attacks in 52 countries with 14,820 controls who did not have heart attacks. The researchers found 9 risk factors that accounted for 90 to 95% of the heart attacks. They were smoking, elevated cholesterol risk ratio, diabetes, high blood pressure, abdominal obesity, stress, low intake of fruit and vegetables, high alcohol intake and lack of physical exercise. Obesity was considered a high risk when the waist circumference measured more than 35 inches in a woman or more than 40 inches in a man. All these 9 risks can be eliminated by lifestyle changes.
  3. The 2006 Health Professional Study spanned over 16 years in a group of 40 to 75 year old doctors without a heart attack at baseline. It noted that male doctors who were lacking the 5 heart attack risk factors had 87% less heart attacks than controls without health lifestyles. What were the lifestyle factors? A body mass index (BMI) of less than 25, being a nonsmoker, being physically active for more than 30 minutes a day, having not more than moderate amounts of alcohol intake and having a diet that was more than 40% plant based.
  4. In 2007 a Swedish study reported on 24,000 women after menopause that had no heart attacks initially. After 6 years of follow-up 308 women developed heart attacks. An analysis showed what the risk factors were for those who developed heart attacks. Those who did not have these risk factors reduced their risk of getting a heart attack by 92%. What lifestyle factors were protective? Four factors were identified: a low-risk diet (consisting of high vegetable and high fruit intake, whole grains, legumes, fish and moderate alcohol intake), not smoking, walking or biking 40 minutes daily and a low waist circumference.
  5. In 2008 the Harvard University released a study that was a further follow-up of the Health Professional study with more than 43,000 men and also the Nurses’ Health Study with more than 71,000 women. The question here was what would prevent the development of strokes? The investigators found that in both groups stroke risk could be reduced by 50% when the following 5 lifestyle factors were adhered to: no smoking, keep the BMI below 25, exercise at least 30 minutes daily with moderate activity, don’t exceed a modest alcohol intake, have a diet intake in the top 40% of fruit and vegetables and whole grains.
  6. A 14 yearlong study from the Netherlands was published in 2014, where almost 18,000 men and women without heart disease at the beginning of the study were followed. More than 600 heart attacks occurred throughout the study. People who stuck to 4 lifestyle habits reduced their heart attack rates by 67%; if they adhered to 5 lifestyle factors they reduced the heart attack rate by 83%. The 4 initial lifestyle factors were: doing an average of 30 minutes of physical activity per day, eating a Mediterranean style diet rich in fruit and vegetables and whole grains, not smoking and having more than one alcoholic drink per month. This gave you a reduced risk of your heart attack rate by 67%. Add one more good habit: sleep 7 or more hours per night on average. This reduces the risk of you getting a heart attack by 83%!
  7. A Swedish heart study with initially more than 20,000 men was going on for 11 years. There were 5 lifestyle habits the investigators identified as essential to reduce heart attack rates. Unfortunately only 1% of the study group adopted all 5 lifestyle factors, but they dropped their chance of getting a heart attack or dying of a heart attack by 86%. The lifestyle factors were: a diet rich in fruit and vegetables, legumes, nuts, whole grains and low fat; not smoking, moderate alcohol consumption, thin waistline and more than 40 minutes of physical activity.

Preserving health and vitality to prevent unhealthy aging

There is a clear pattern in all of these large studies. A healthy lifestyle preserves your health by keeping your joints and muscles in good working order. Your heart and lungs are staying well conditioned, because you engage in cardiovascular training every day. This keeps your nitric oxide going, which is an important signaling molecule that in turn reduces your blood pressure.

When we remove disabling diseases like strokes and heart attacks and prevent diabetes from developing, life expectancy is increasing. When people remain physically active even in old age, this translates into fewer disabilities and less frailty. Even Alzheimer’s disease is observed to occur less when good lifestyle habits are adhered to.

Prevent Unhealthy Aging

Prevent Unhealthy Aging

Conclusion

The studies cited here show how lifestyle factors can make a significant difference in preventing heart attacks and strokes. In the past even doctors ignored the risk of smoking. A few years back conventional medicine negated that lifestyle factors could make a difference. Now we have more studies than we need to prove that this is so. It is more important that we adhere to as many of the lifestyle factors identified in these studies to make a real difference in our lives. We also need to set an example to the next generation and to our peers. Adopting healthy lifestyle factors has to become a cultural habit for society at large. This will help reduce healthcare costs, but most importantly this will help you and me to live longer, healthier lives.

High Vitamin D3 Prevents Cancer

In the last few years we learnt a lot about vitamin D3, but the newest thing is that high vitamin D3 prevents cancer.

Researchers at the University of California, San Diego School of Medicine reported that with respect to several cancer types higher doses of vitamin D3 led to less cancer over a period of time.

The cancers investigated were colon cancer, breast cancer, and lung and bladder cancer. As people do absorb vitamin D3 differently, the researchers found that the best way to measure vitamin D3 concentration in the body is to use serum 25-hydroxyvitamin D (25(OH)D). In the past not much attention was paid to this matter. However, several studies including the present study showed that in patients who had a lower level of 20 ng/ml cancer rates were higher.

The researchers used data from two prior studies, a randomized clinical trial of 1,169 women and a prospective cohort study of 1,135 women. The researchers found that the age-adjusted cancer incidence was 1,020 cases per 100,000 person-years in the randomized clinical trial, called “Lappe cohort”. The other prospective cohort study was called the “GrassrootsHealth cohort” with an age-adjusted cancer incidence of 722 per 100,000 person-years. The interesting fact was that the Lappe cohort median blood serum level of 25(OH)D was 30 nanograms per milliliter, while the GrassrootsHealth cohort had a higher level of 25(OH)D of 48 ng/ml. This likely explains the lower cancer rate in the GrassrootsHealth cohort. In order to increase the statistical significance the two trials were combined. The striking finding was that above 40 ng/ml the overall cancer risk was more than 71% lower than for the group of people whose level of 25(OH)D was 20 ng/ml or lower. The above ScienceDaily article was based on this scientific study.

Other studies showing high vitamin D3 prevents cancer

  1. In a 2015 study Afro American men were found to have 71% less prostate cancer, if their serum 25-hydroxyvitamin D level was at least 30 ng/ml or higher.
  2. This 2006 study reported a 14-year prospective follow-up in men where all cancers were counted and blood serum 25-hydroxyvitamin D levels were correlated to cancer incidence. An increase of 25 nmol/L (=10 ng/ml) in predicted serum 25(OH)D level was associated with a 17% reduction in total cancer incidence, with a 29% reduction in total cancer mortality and a 45% reduction in digestive-system cancer mortality. These investigators stated that it takes about 1500 IU of vitamin D3 increase per day to achieve an increment of serum 25(OH)D increment of 25 nmol/L (=10 ng/ml).
  3. A publication from the University of Arizona Cancer Center in Jan. 2016 is more critical of the evidence regarding vitamin D3 and the claim that it lowers cancer rates. They reviewed the cancer literature and found that for colorectal cancer there is a clear inverse relationship between serum 25(OH)D levels on the one hand and rates and mortality of colorectal cancer on the other hand. However, with breast cancer the literature was more divided. Only higher vitamin D levels were related to a lower risk for progression of breast cancer and a lower mortality rate. Randomized, double-blind clinical trials with regard to breast cancer failed to show effectiveness on cancer prevention or reduction of mortality. For prostate cancer conditions were similar with the exception of a study using 4000 IU of vitamin D3 per day, which inhibited progression of prostate cancer.
  4. In a mouse model using a carcinogen to induce ovarian cancer there was an inverse dose-relationship between vitamin D3 and ovarian tumor development both in tissue culture and in the animal.

How high vitamin D3 prevents cancer

  1. Several studies have attempted to speculate how vitamin D3 may prevent cancer. Chirumbolo summarized the literature and noted that vitamin D3 has been shown to function as an immune cytokine stimulating the immune system non-specifically.  Vitamin D3 is also anti-inflammatory and counters insulin resistance and inflammatory kinins in obesity. Flavonoids with their antioxidant activity are also cancer preventing. As we know that low levels of vitamin D are associated with higher cancer frequency it is important to use vitamin D3 as supplements in our diet.
  2. This Chinese study examined the effects of vitamin D3 on cancer prevention. It found that vitamin D3 combines three specific actions in one. Vitamin D3 is anti-proliferative meaning that it stops uncontrolled cell division. Secondly, it has an apoptotic (cell death) effect, which means it supports the removal of cells that are dying. If they are dying, but not removed, cancer can occur from these cell remnants. The third effect of vitamin D3 is that it has differentiating effects in several malignant cell types. When cancer cells are non-differentiated (=more immature cells) cancer can multiply quickly. When cancer cells are becoming more specific cells uncontrolled multiplication is much more difficult. This is an effect that controls the speed by which cancer cells divide and how quickly cancer metastasizes.
High Vitamin D3 Prevents Cancer

High Vitamin D3 Prevents Cancer

Conclusion

There still is some confusion about the effects of vitamin D3 regarding cancer prevention. In colorectal cancer the statistics are clear: vitamin D3 can significantly prevent colorectal cancer to a large extent. There are also preventative effects in breast cancer and prostate cancer, but individuals may have to take at least 4000 IU of vitamin D3 or more. This is particularly true in higher latitudes where sunlight exposure is lower in the wintertime. Also, people absorb vitamin D3 differently. For this reason it is important to at least check your serum 25-hydroxyvitamin D levels on a few occasions. This will tell you whether your vitamin D3 supplementation is sufficient. Aim for levels in the 50-80 ng/ml, which is health promoting.

Apart from cancer prevention vitamin D3 is also important for prevention of cardiovascular disease (particularly in diabetics), osteoporosis and Alzheimer’s disease.

Healing Powers Of Green Tea

Powerful catechins that are a special form of bioflavonoids provide the healing powers of green tea. Research teams have proven that these catechins are only contained in green tea, not so much in black tea. The most effective of several catechins contained in green tea is EGCG, which stands for EpiGalloCatechin-3-Gallate. It crosses the blood/brain barrier and is very important for the protection of the brain from Alzheimer’s disease. But green tea or green tea extract has a diversified pharmacological action. It is said to protect you from cardiovascular disease, from obesity, from diabetes, from autoimmune disorders, from cancer and from Alzheimer’s and dementia.

In the following I like to comment on how green tea or its extract can protect from all of these diseases.

Alzheimer’s disease

Although there are 5 or 6 approved anti-Alzheimer’s drugs, none of them work for very long. They may at best postpone the deteriorating memory for 6 months, but then the effect of the drug wears off. The reason is that the drugs do not stop the production of the deadly beta-amyloid. It is the beta-amyloid that damages nerve cells that you want to preserve so you can think and memorize. In contrast a simple phytochemical, the catechin EGCG has been shown in animal experiments and in human trials to stop beta-amyloid production and increase solubility of beta-amyloid fragments in the brain. The end result is better memory and no further deterioration.

In a study of 13,988 elderly Japanese observed over 3 years the group that consumed 3 to 4 cups of green tea daily had 33% less strokes, cognitive impairment and osteoporosis.

Researchers at the University of Basel, Switzerland enrolled 12 healthy volunteers aged 21 to 28 and fed them extracts of green tea or placebo fluid via feeding tubes. This was done to rule out taste as a factor. Functional MRI scans were applied as the subjects were given memory-stimulating tasks. Only the green tea extract was boosting activity in the frontal brain of the subjects. This was located in a specific area, called dorsolateral prefrontal cortex. This area is known to be involved with language comprehension, reasoning and learning. It also switches short-term memory into long-term memory, called working memory processing.

Studies in animals have shown that nerve cells are protected from the toxic effect of beta-amyloid and at the same time the production of new brain nerve cells (neurons) is triggered by green tea extract. This is really good news for Alzheimer’s disease patients and their families: green tea extract delays further memory deterioration and stimulates the development of new nerve cells in the brain!

Cardiovascular disease

In a 2006 Japanese study 40,530 Japanese adults aged 40 to 79 years without history of stroke, coronary heart disease, or cancer at baseline were observed for 7 years. Diaries were kept about how many cups of green tea each person was drinking per day. The biggest effect was seen with regard to prevention of heart attacks and strokes.

Men had a mortality reduction of 12% for heart attacks when they drank 5 cups or more of green tea; in women the corresponding mortality reduction for heart attack was 31%, a bigger effect. Overall mortality from strokes was lower than from heart attacks making the effect of green tea consumption even more beneficial with respect to stroke prevention. In this study no cancer preventing effect was observed for green tea.

Obesity

It appears that green tea increases heat production and burns fat in the process. There was a small effect in terms of weight loss and a beneficial effect increasing the protective HDL cholesterol in this 2012 Polish study on obese patients. The authors compared either 379 mg of green tea extract, or a placebo, daily for 3 months. They concluded: “The results of this study confirm the beneficial effects of green tea extract supplementation on body mass index, lipid profile, and total antioxidant status in patients with obesity.”

Diabetes

Although there are claims in some studies that green tea would prevent diabetes, this question was thoroughly investigated in this Chinese 2014 study.

No effects were noted on fasting blood sugars or on hemoglobin A1C values, a very sensitive indicator for the presence or absence of diabetes. All these lab tests were unchanged following consumption of green tea or green tea extract. Forget using green tea for diabetes prevention; cut out sugar and starchy foods instead.

Autoimmune disorders

Sjogren’s syndrome and lupus are both autoimmune diseases. Green tea extract has shown in humans that symptom severity can improve; green tea polyphenols (GTPs) possess anti-inflammatory properties that benefit patients with autoimmune diseases.

In an animal model arthritis researchers determined that T helper cells are weakened and bone resorption is inhibited by EGCG from green tea extract.

Researchers at Harvard Medical School, Boston, MA have noted that green tea extract is useful in calming down the immune response in autoimmune diseases. They concluded: “Altogether, these studies identify and support the use of EGCG as a potential therapeutic agent in preventing and ameliorating T cell-mediated autoimmune diseases.”

Cancer

Many research papers have found that EGCG from green tea extract has immune modulatory effects that are useful in combination with chemotherapy. A combination of cisplatin therapy with green tea extract has been found to have more effects on colorectal cancer and ovarian cancer than each one on its own. Similarly chemotherapy of breast cancer had better results in humans when EGCG from green tea extract was added as an immune modulation. More research, particularly in humans is needed to fully understand the mechanism of action of EGCG.

Toxicity of green tea extract

Animal experiments showed that higher doses of green tea extract could cause toxicity in the liver and in the nose of rats and mice. I was not able to find objective evidence for green tea toxicity in the PubMed system with respect to humans.

Conclusion

Perhaps the most important discovery regarding green tea extract is that it crosses easily through the blood/brain barrier into the brain. This can postpone Alzheimer’s disease and can even lead to new neuron formation. The beneficial cardiovascular effects are also useful and combine well with exercise and good nutrition for prevention. Particularly stroke prevention is a useful property of EGCG from green tea extract. The effect on obesity is marginal whereas there was no effect of green tea on prevention of diabetes. The immune modulatory effect of green tea extract is useful in the treatment of autoimmune diseases and of cancer. Existing treatments for these conditions are becoming more effective by adding green tea extract.
