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.

Health Risks Of Night Shifts

One of the news stories in 2016 was about health risks of night shifts. The Bureau of Labor Statistics reported in 2000 that 15 million workers (16.8 % of the working population) were doing alternative shifts (night shift work mixed with daytime shifts). In 2016 they reported 14.8% were working alternate shifts. Among blacks, Asians and Latino Americans the percentage of working alternative shifts was higher, namely 20.8%, 15.7% and 16%, respectively.

Shift work is more common in certain industries, such as protective services like the police force, food services, health services and transportation.

Evidence of health risks of night shifts

There are several publications that showed evidence of health risks of night shift workers. Here is a random selection to illustrate the health risks of night shifts.

  1. A study from 2015 examined the sleep patterns of 315 shift nurses and health care workers in Iranian teaching hospitals. They found that 83.2% suffered from poor sleep and half of them had moderate to excessive sleepiness when they were awake.
  2. This South Korean study examined 244 male workers, aged 20 to 39 in a manufacturing plant. Blood tests from daytime workers were compared to night shift workers. Inflammatory markers like the C-reactive protein and leukocyte counts were obtained. Night shift workers had significantly higher values. The investigators concluded that shift workers have increased inflammatory markers. This is a sign of a higher risk of developing cardiovascular disease in the future.
  3. A Swedish study found that white-collar shift workers had a 2.6-fold higher mortality over a control group of daytime white-collar workers.
  4. Another study compared night workers in the age group of 45 to 54 with daytime workers and found a 1.47-fold higher mortality rate in the night shift workers.
  5. In a study from China 25,377 participants were included in a study that investigated cancer risk in males with more than 20 years of night shift work. They had a 2.03-fold increased risk to develop cancer compared to males working day shifts. Women with night shift work were unaffected with regard to cancer.
  6. A Polish study examined hormones and the body mass index (BMI) among 263 women who worked night shifts and 269 women who worked day shifts. When night shift workers had worked more than 15 years at nights, their estrogen levels, particularly in postmenopausal women were elevated compared to the daytime workers who served as controls. The BMI was also increased in the nighttime workers.
  7. Chronic lymphocytic leukemia (CLL): a study in Spain showed that working for more than 20 years in rotating night shifts was associated with a 1.77-fold higher risk of developing CLL. The authors noted that melatonin levels in that group were much lower than in controls that worked only day shifts. Working in straight night shifts did not show higher risks of CLL compared to daytime workers.
  8. In a Korean study from Seoul 100 female medical technologist who worked nighttime had their melatonin levels tested, which were compared to daytime workers.  They measured 1.84 pg/mL of melatonin for the nighttime workers compared to 4.04 pg/mL of melatonin in the daytime workers. The authors felt that this is proof that the diurnal hormone system has been disrupted. When the melatonin level is altered, the circadian hormone rhythm is also changed.
  9. A group of 168 female hospital employees doing rotating nightshift work in Southern Ontario hospitals were compared to 160 day workers. Cortisol production was assessed. Cortisol production in day workers and in shift workers on their day shift was similar. However, shift workers on their night shift had flatter cortisol curves and produced less cortisol. The authors felt that this disruption of cortisol production would explain why rotating night shift workers have a higher risk of cardiovascular diseases.
  10. A Danish study with female nurses followed 28,731 nurses between 1993 and 2015. Daytime nurses were compared to rotating nighttime nurses and the incidence of diabetes was measured. Night shift workers had a risk between 1.58-fold to 1.99-fold when compared to daytime workers to develop diabetes. The risk for evening shift workers was less (between 1.29-fold and 1.59-fold).

Diurnal hormone rhythm behind health risks of night shifts

Your body has its own rules. It rewards you, if you sleep 7 to 8 hours during the night, but it will penalize you severely, if you turn it upside down. The reason is our built-in diurnal hormone rhythm. A peak of melatonin regulates sleep during the night. Melatonin is released by the pineal gland (on the base of the skull) when it gets dark outside. Daytime wakefulness is regulated by the stress hormone cortisol from the adrenal glands. These two hormones inhibit each other, cortisol inhibits melatonin and melatonin inhibits cortisol. All the other hormones are also regulated according to the diurnal rhythm: testosterone is highest in the morning, human growth hormone is highest between midnight and 3 AM etc.

When you work daytime shifts, your diurnal hormone rhythm is unchanged. But if you work night time shifts, your hormones have to adapt. This is very similar to traveling east or west where you cross several time zones. Your internal diurnal hormone system has to adjust to these changes. Typically it takes 1 day to adjust to a 1-hour time zone difference.

In people who work permanent night shifts, the hormone changes stay adjusted and there is no further switching. But most employers want to be “fair” to everybody, so they introduced the rotating night shifts, which as all the publications cited above show is the worst thing you can do. It messes with your diurnal hormone rhythm, and some people never switch completely to the new hours worked. They don’t get enough daytime sleep because the kids are loud during the day etc. The rotating shift workers are running the highest risk of getting cancer, diabetes, cardiovascular diseases, obesity, cancer, leukemia, and they have low levels of melatonin.

Health Risks Of Night Shifts

Health Risks Of Night Shifts

Conclusion

When shift workers work constant night shifts, this is less stressful to our system than the more common rotating shift work. This is where you work night shifts for a period of time, then the schedule switches to day shift, and you keep on rotating. The least health risks are associated with regular daytime work. People exposed to rotating night shifts suffer from poor sleep. They have a higher risk of gaining weight, getting obese and acquiring diabetes in time. They are at a higher risk for heart attacks, strokes and cancer. All-cause mortality is about twofold higher than for workers who work day shifts.

The underlying problem seems to be a disturbance of the diurnal hormone rhythm. Normally this regulates our waking/sleeping rhythm and keeps us healthy. But with nighttime work melatonin production weakens, cortisol production is reduced and hormone rejuvenation during rest periods suffers greatly. This weakens the immune system, allows cancer to develop and leads to chronic inflammation causing cardiovascular disease and diabetes. The remedy to prevent this from happening is to catch little naps whenever you can during the day and, if at all possible, work daytime shifts permanently.

High Insulin Levels Can Cause Alzheimer’s

Research published in April 2016 shows that high insulin levels can cause Alzheimer’s. Alzheimer’s disease has been known to occur more often in diabetics. But until recently it was not known why there would be this association. New research from New York University (NYU) has shed light on this puzzle. The key is an enzyme that breaks down insulin, called insulin-degrading enzyme (IDE). Melissa Schilling (no relation to me), an innovation professor at NYU has discovered the metabolic pathway between diabetes and Alzheimer’s disease. This finding has enormous implications regarding the prevention of Alzheimer’s, as I will discuss below. Here is a link to the original paper.

Background information about Alzheimer’s

Alzheimer’s disease affects about 5.2 million Americans and 44 million people worldwide. There is a progressive loss of cognitive functioning over a long period of time due to senile plaques in the cerebral cortex and the subcortical areas of the brain. These senile plaques are made up of amyloid-beta substance and of neurofibrillary tangles. This protein material is like glue, which prevents the neurons from working properly and causes memory loss and the confusion, which is so typical for Alzheimer’s patients. Normally amyloid-beta is in solution and prevents lipoproteins in the brain from oxidizing. But when the insulin-degrading enzyme is busy breaking down high levels of insulin, this enzyme system is overwhelmed. Amyloid-beta gets supersaturated, as it is not eliminated at a normal speed. This leads to the glue-like deposits of amyloid-beta in Alzheimer’s brains.

It is estimated that in 2004 the direct cost to the US of Alzheimer’s disease was $214 billion. By 2050 this could go up to $1.5 trillion, if no cure is found.

High insulin levels can cause Alzheimer’s, but other mechanisms too

Professor Schilling found in her research that there are four main malfunctions that can lead to high amyloid-beta in the brain of Alzheimer’s patients.

  1. With diabetes type1, when the patient does not receive enough insulin, the insulin-degrading enzyme in the brain is not working hard enough. This results in inadequate removal of amyloid-beta from the brain and neurofibrillary tangles of amyloid-beta are deposited.
  2. IDE requires zinc as a co-factor to work properly in breaking down amyloid-beta. Zinc deficiency is quite common, particularly in older people. With this mechanism insulin levels are normal, but amyloid-beta is removed poorly, as IDE function is diminished.
  3. In early type 2 diabetes there are high insulin levels and there is a competitive inhibition of the elimination of insulin and amylin-beta. This is probably the most common form of getting Alzheimer’s disease.
  4. Excess production of an amyloidogenic protein can lead to an overabundance of amylin-beta, which overwhelms the insulin-degrading enzyme.

What treatment options are there for Alzheimer’s disease?

Several implications follow from the four mechanisms that were described above.

  1. If a type 1 diabetic patient is insulin deficient, intranasal insulin would be beneficial.
  2. If the patient has type 2 diabetes, intranasal insulin or injected insulin would be the wrong approach. As stated earlier, there is the competitive inhibition of the elimination of insulin and amylin-beta. It is the insulin-degrading enzyme, which is the limiting factor. Simple dietary changes are needed where sugar is cut out and starchy foods are limited. This normalizes insulin levels and the IDE function returns to normal.
  3. Alzheimer’s patients and patients with mild cognitive dysfunction should be tested with glucose tolerance tests (GTT). It the test is abnormal, a knowledgeable dietician should be consulted.
  4. Obesity is strongly associated with hyperinsulinemia and diabetes. Again frequent GTT should be done followed by dietary intervention when abnormal.
  5. Professor Melissa Schilling stated that 86 million Americans are pre-diabetic, but they have no symptoms. Only glucose tolerance testing can diagnose that condition. This will prevent a lot of cases of diabetes and Alzheimer’s disease.
  6. Large parts of the population have no knowledge of the glycemic index of carbohydrates. In order to limit glucose overload and excessive insulin production educational nutritional programs are needed. This will be a powerful tool in Alzheimer’s disease prevention.
High Insulin Levels Can Cause Alzheimer’s

High Insulin Levels Can Cause Alzheimer’s

Conclusion

It has been known for some time that diabetics have a higher rate of Alzheimer’s disease. Alzheimer’s has also been called “Diabetes of the brain” or “Type 3 Diabetes”. This new research has shed some light on the connection of elevated insulin to Alzheimer’s disease. It was news to me that there is a competitive inhibition of the elimination of insulin and amylin-beta via the insulin-degrading enzyme. It boils down to recognizing that sugar overconsumption causes Alzheimer’s disease. If you want to keep your brain power until a ripe old age, you better eliminate a lot of sugar and adopt a healthy Mediterranean diet.

Sugar Can Cause Heart Attacks

Recently an online medical journal article from JAMA has revealed that sugar can cause heart attacks. As the Guardian reports, this analysis of influence peddling of the sugar industry going back 60 years has had far-reaching effects by confusing the public and policy makers in the US and around the world. At the same time the interference of the sugar industry was protecting its own interests. It increased sugar sales, but made people sick with obesity, diabetes and cardiovascular disease. This story is similar to the tobacco industry that was able for years to cover up that cigarette smoke is causing heart attacks and lung cancer.

Denying that sugar can cause heart attacks

When the English physiologist John Yadkin noted in the 1960’s that sugar was elevating cholesterol and triglycerides, the sugar industry was panicking. Something had to be done to stop this new research. As we can read in the online JAMA review the Sugar Research Foundation (SRF) had 319 correspondences (1551 pages) with Roger Adams. He was a professor who served on the SRF’s scientific advisory board (SAB) from 1959 to 1971. Another piece of evidence of influence peddling came from a review of correspondence between the SRF and D. Mark Hegsted. He was professor of nutrition at the Harvard School of Public Health. At the same time he was co director of the SRF’s first coronary heart disease research project. This took place from 1965 to 1966. There are 27 documents totaling 31 pages in the Harvard medical Library. It is clear from this correspondence that the SRF was looking for a way to undermine the new research findings of negative effects of sugar. The SRF was looking for a way to confirm that fat reduction would be beneficial for patients. This way many people would be put on a low fat diet, which in turn would ensure continuing and rising sales of sugar.

New evidence that sugar can cause heart attacks

New research came out by D. Mark Hegsted in the Annals of Internal Medicine in June 1965. It linked sugar consumption to cardiovascular disease. It noted that blood sugar levels were a better predictor of hardening of arteries than cholesterol levels or high blood pressure. Another paper stated that it was sugar rather than starches causing high triglycerides in the blood. He hypothesized that “perhaps fructose, a constituent of sucrose but not of starch, was the agent mainly responsible.” An editorial in the same publication noted that these new findings corroborated Dr. Yudkin’s previous research that sugar could cause heart attacks.

The sugar industry was very concerned about these studies. If publicized widely, it would have the capacity to lower sugar sales.

Sugar can cause heart attacks, but review paper ignores this

On July 1, 1965, the SRF’s Hickson visited D. Mark Hegsted to discuss his publication. He wanted him to be part of an extensive literature review that would show that it was too much saturated fat that was the cause of high cholesterol and triglycerides, not sugar. It also should state that a lowering of fat content from 40% to 20% was necessary and that polyunsaturated fatty acids should be used to replace much of the fat. The fact that the food industry would quietly increase sugar content in processed foods was not mentioned. The review paper was called “Project 226”. It resulted in a 2-part literature review by McGandy, Hegsted, and Stare. It was entitled “Dietary Fats, Carbohydrates and Atherosclerotic Disease,” and was published in the New England Journal of Medicine (NEJM) in 1967. Industry and non-industry funding of the review authors’ experimental research was disclosed. However, the funding by the Sugar Research Foundation was omitted. The authors of the study received handsome amounts of money from the SRF for their efforts. The story that was fabricated is all too well known, but false. It claimed that the medical literature would have shown that a reduction of saturated fat intake would lower cholesterol. It ignored triglyceride levels and stated that only cholesterol levels were significant with respect to coronary artery hardening. It also stated that replacement of saturated fat with polyunsaturated fatty acids like corn oil would also be beneficial in reducing heart attack rates.

Effect of the literature review on heart attack rates

Sadly the NEJM literature review has resulted in government policy for decades where the gospel was preached that a low fat diet would prevent heart attacks. The food industry has prepared processed foods, all low in fats and high in sugar that were supposed to he healthy. But the extra sugar made people fat, it did not decrease heart attack rates, but made them more frequent. Strokes were also on the rise and diabetes has become rampant. The reliance on corn oil has introduced another problem: omega-6 fatty acids are now consumed at an alarming rate. Corn oil has a 1:59 ratio for omega-3 to omega-6 fatty acids.

This means that corn oil contributes to the lack of omega-3 fatty acids in our food. When the ratio of omega-3 to omega-6 fatty acids falls below 1:3 or 1:4 the metabolism changes towards inflammation as the arachidonic acid system switches toward inflammation. Cardiologists have pinpointed inflammation as an important cause of hardening of arteries. Fish oil, a rich source of omega-3 fatty acids helps to prevent hard attacks and strokes.

The end result of the confusion regarding fat, sugar and heart attacks caused by the biased literature review meant misery, suffering and death for many for decades. But recently there has been a renaissance of Dr. John Yadkin’s research: Now it is clear what sugar is doing and how it affects our health.

How sugar can cause heart attacks and more

It is clear that sugary soda has detrimental effects on us: as little as one or two cans of sugary soda drinks per day lead to

  • 26 percent greater risk of developing type 2 diabetes,
  • A 35 percent greater risk of heart attack or fatal heart disease, and
  • A 16 percent increased risk of stroke.

Dr. Frank Hu has participated in a study that spanned over 24 to 30 years and examined the replacement of saturated fat with polyunsaturated fatty acids (PUFA), monounsaturated fatty acids and whole grain carbohydrates. The study involved 84,628 women (Nurses’ Health Study, 1980 to 2010), and 42,908 men (Health Professionals Follow-up Study, 1986 to 2010). The diet was assessed with detailed questionnaires every 4 years. 7,667 cases of cardiovascular disease (CHD) occurred during the long observation times. Compared to controls that did not change their diet with respect to saturated fatty acid intake, those who replaced with PUFA had 25% less CHD, those who replaced with monounsaturated fatty acids had 15% less CHD and those who replaced saturated fatty intake with whole grains had 9% less CHD. In contrast, a subgroup that had replaced saturated fatty acid intake with carbohydrates from refined starches/added sugars ended up with a 10% increase of CHD.

We know now that sugar can increase cholesterol and triglycerides as Dr. John Yadkin has said in the 1960’s.

We also know that sugar can cause arthritis when combined with low omega-3 fatty acids and high omega-6 fatty acids. In the 1950’s Dan Dale Alexander wrote a book called “Arthritis and common sense”. The medical establishment did not accept that simple remedy and Dan Dale Alexander was classified as a “quack”. However, Dr. Mirkin describes a study from Berlin that later confirmed that Dan Dale Alexander’s observation was correct: an emulsion made by shaking orange juice with cod liver oil and taken three times per day on an empty stomach would indeed improve osteoarthritis.

High glycemic foods (sugar, starchy foods) were associated with breast cancer, colorectal cancer and endometrial cancer. The majority of trials showed this association although not all. The more obese patients were, the more pronounced the insulin resistance was and the more the relationship to these cancers became apparent. A diet that is high in starchy foods like potatoes, rice and bread is causing pancreatic cancer as was shown by researchers at the Dana-Faber Cancer Institute, Brigham and Women’s Hospital and Harvard School of Public Health.

Sugar Can Cause Heart Attacks

Sugar Can Cause Heart Attacks

Conclusion

The low fat/ high glycemic diet was a fad-diet based on fictitious science, sponsored by the sugar industry. In a way it became a human experiment and resulted in 60 years of suffering to show that this diet did not work. It caused the obesity wave, a wave of heart attacks, strokes and cancer, all caused by too much sugar in the diet. Associated with this are the consumption of processed foods with too much sugar and an abundance of omega-6 fatty acids causing inflammation and hardening of the arteries.

We finally know that sugar raises cholesterol (LDL cholesterol in particular) and triglycerides. This leads to fat deposits and hardening of the arteries resulting in strokes and heart attacks. Remove refined sugar, limit your starchy food intake and eat fish as a source of omega-3 fatty acids. Feast on vegetables, salads and have some nuts as another source of omega-3 fatty acids and you are well on your way to preventing heart attacks, strokes and many cancers. After reading all the facts it does no longer make sense to be a victim of the sugar industry and the associated health risks.

Seven Steps To Live Over 100 Years

Forbes invited me to publish a blog I wrote for Quora, “Seven steps to live over 100 years”.

The topic of habits by people who live more than a hundred years has been reviewed many times in the media. It continues to be popular. Here are seven things you can do to stay healthy followed by an explanation why.

Seven steps to live over 100 years – step1: Stay active

You want to stay active every day, even if you retire. You want to move and keep your mind busy. Part of that is to do a daily formal exercise routine to keep those muscles toned, which will prevent falls in the future.

Explanation: when you keep your muscles toned and you move about, your balance organ and coordination remains sharp, you are less likely to fall and break a hip. 50% of those who sustain a hip fracture die.

Seven steps to live over 100 years – step 2: Eat a healthy diet

Eat a Mediterranean type diet or follow the Okinawan diet. These diets contain less meat (or no meat as in the Seventh Day Adventist diet), but lots of vegetables and fiber. This keeps your cholesterol down, your arteries open and your metabolism controlled, preventing diabetes. If you are not obese and you have no diabetes, you are going to be OK with your cardiovascular system for decades to come.

Explanation: Heart attacks are still on top of the mortality list. Avoid them and you got it made, if you want to make it to 100 and beyond. But we need to stay away from the poor fats and the obsession about eating beef. Red meat, if eaten too often gives you a higher risk of getting cancer and heart disease. So eat it only once a week at the most, the rest would be chicken, turkey meat or fish. Nothing wrong with a vegetarian meal, let’s say kidney beans or lentils on a day in between. This still gives you protein for your muscles, but spares you a heart attack.

Seven steps to live over 100 years – step 3: Take care of your teeth

Brush your teeth and floss every day. This will control the bacteria in your mouth and prevent leakage into your blood affecting your heart valves. Studies have shown that this prevents heart attacks.

Explanation: When I heard this first about 20 years ago, I found it strange. But the literature is clear: chronic gingivitis is associated with bacteria that grow on the gums and spread into your blood. They can then colonize your heart valves and even the lining of the arteries, particularly where there is already hardening of the arteries (arterial plaque). This can lead to heart valve disease like mitral valve disease or heart attacks.

Seven steps to live over 100 years – step 4: prevention of disease

See your physician right away if there is a new skin lesion or anything that is different on your body. Removal of early cancer and treatment of any early medical condition is always easier to treat than waiting until it is out of control. Particularly with cancer treatment at an early stage, which usually involves only a small surgical procedure, this will reward you with a ripe old age.

Explanation: I learnt this point in general practice. Patients who waited until small problems become big problems were always much worse off than patients who saw me for small problems that we could remedy at an early stage. As mentioned above this is particularly important in cancer cases, as usually stage 1 and 2 of a cancer is curable with surgery. Once you get lymph node metastases and distant metastases, the cancer is much more difficult to treat, if at all. This is a principle that is pretty much true for any disease. The prevention factor is huge. Make use of it!

Seven steps to live over 100 years – step 5: Lifestyle matters

Watch excesses like smoking (cut it out!), alcohol intake, and recreational drugs. Smoking causes heart attacks, strokes, and cancers, which shorten your life. Recreational drugs just interfere with your body chemistry and have side effects. Cut them out, if you cherish growing older than 100. Alcohol needs to be kept at a very low consumption, if you want to preserve your liver, which is your central metabolic organ. If you can’t handle moderation with alcohol consumption, cut it out. No one has died from not consuming alcohol.

Explanation: I have already explained why lifestyle choices matter. The alcohol question is one that will be discussed back and forth for centuries. There are cardiologists who tell you that men should drink 1 to 2 drinks per day and women 1 drink per day and we all live longer, because of prevention of heart disease. The wine industry makes sure that you will hear this cardiology rule. It is true that centenarians often drink one glass of red wine per day. But there are plenty of centenarians who never drank in their life. It is a matter of personal choice.

Seven steps to live over 100 years – step 6: Avoid obesity and diabetes

I did mention to avoid obesity under point 2 above, which is associated with metabolic syndrome and diabetes. Your ideal body mass index should be in the 21 to 22 range. You can achieve this by following the diets I mentioned above. You should cut out sugar and starchy foods.

Explanation: I have followed such a diet since 2001 and my body mass index is between 21 and 22. I grew up in Germany where an emphasis was put on sweets and starchy foods. Needless to say my modified Mediterranean diet deviates from the good old German diet significantly. I find healthy food very tasty.

Seven steps to live over 100 years – step 7: Sleep and hormones

Getting sleep regularly, having an optimistic outlook on life, and having good relationships help to keep the immune system strong and keep your hormones balanced. This in turn will keep you healthy emotionally and physically.

Explanation:

There are two comments I like to make. One is that when you have calm nerves, and your emotions are balanced, your stress hormones are controlled. We know that people who are laid back and easy going live longer. The type A personality is the one who gets a heart attack.

The other point is that hormones have running times. When they start missing, we get menopause or andropause. When we are in our 50’s it is time to have your hormones checked by a knowledgeable health practitioner (naturopath, anti-aging physician). At this point regular physicians are mostly uneducated about bioidentical hormone replacement. I mention this as in European studies it has been shown that replacement of missing hormones with bioidentical hormones resulted in more youthful lives. Life expectancy can be prolonged by 15 years using bioidentical hormones according to Dr. Hertoghe, an endocrinologist in Belgium. http://www.askdrray.com/life-extended-by-several-decades/

Seven Steps To Live Over 100 Years

Seven Steps To Live Over 100 Years

Conclusion

People have always been fascinated about the factors that lead to a healthy age above 100 years. I am suggesting that you concentrate on enjoying your life and keeping toxins out. Engage in some form of exercise or stay active all the time. Adopt a healthy diet. This is where perhaps most people go wrong. They think they can go on pouring junk foods and alcohol down their throats and never get heart disease or cancer. The truth is not quite like that. We do need to adopt a healthy diet like the Mediterranean diet. We also need to limit drinking to a healthy level. Replacing missing hormones with bioidentical ones will prolong your life as well. Given these recommendations, happy journey to 100 and beyond!

Mediterranean With Healthy Fat

If you want to lose weight, have you considered eating Mediterranean with healthy fat? A lot has changed in recent years regarding recommendations for healthy food intake. In the eighties and nineties the low fat diet was recommended, which unfortunately was high in carbs and led to obesity. What we have learnt from this is that carbohydrates that get broken down in the gut into sugar are converted into fatty acids and stored as fat.

Studies regarding diets with unhealthy and healthy fats

  1. Here is a prospective study that followed 120,877 U.S. women and men over a longer time. Every 4 years it was noted that for potato chips 1.69 lbs. were gained, for potatoes 1.28 lbs., for sugar-sweetened beverages 1.00 lb., for unprocessed red meats 0.95 lb. and for processed meats 0.93 lb. On the other hand from vegetables there was a weight loss of −0.22 lb., for whole grains −0.37 lb., for fruits −0.49 lb., for nuts −0.57 lb. and for yogurt −0.82 lb. Cheese was also investigated and was found to be mostly neutral in terms of weight gain, while butter did cause weight gain.
  2. In a study from Spain that was published in the Lancet in June 2016. 7447 asymptomatic men (aged 55–80 years) and women (aged 60–80 years) were followed for about 5 years. They all had type 2 diabetes and three or more cardiovascular risk factors. They were randomly assigned to three Mediterranean diet types: a Mediterranean diet with olive oil, a Mediterranean diet with nuts and a control group on a low fat Mediterranean diet. The interesting finding after 5 years was that both the patients on the Mediterranean diet with nuts and with olive oil lost some waist circumference. Their weight loss was 0.95 lbs. for the olive oil group and 2.82 oz. in the Mediterranean diet group with nuts. The Mediterranean diet group with olive oil had lost 0.22 inches in the waistline, the other group on nuts lost 0.38 inches. These are hardly impressive losses! The researchers concluded that fat restriction is not necessary on the Mediterranean diet, as there was no weight gain with unrestricted healthy fats after 5 years.

Dr. Dariush Mozaffarian, a cardiologist and epidemiologist of the Tufts Friedman School of Nutrition Science & Policy wrote an editorial regarding this Spanish study: ”A handful of nuts may be 160 calories, which is more calories than a can of Coke, but that doesn’t mean the can of Coke is a better choice”. He added: “Salt, sugar, starch, processed food and trans fats should be off the menu, not fat. Healthy foods are healthy foods, and bad foods are bad. It doesn’t matter, if the food is low fat or high fat. This is a separate issue.”

Mediterranean With Healthy Fat

Mediterranean With Healthy Fat

Conclusion

When wanting to lose weight, the key is to pay attention to your carb intake. Make sure it consists of unrefined carbs. You will do this if you eat vegetables and fruit. Cut out sugar and starchy foods as much as you can. Have lean, clean meats, but avoid red meat except perhaps for every two weeks some grass fed beef. Eat fish (important for its content of omega-3 fatty acids), also enjoy yogurt, nuts, olive oil and avocados. It is an extra benefit if you add regular exercise to this as well. You will notice that you gradually shed the unnecessary pounds. This is not a program for just a month or two. To stay well, make it a new lifestyle!

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.

Genetic Screening For Better Health

Dr. Matt Pratt-Hyatt gave an overview about genetic screening for better health at the 23rd Annual World Congress on Anti-Aging Medicine on Dec. 13, 2015 in Las Vegas. The talk was entitled ”Genetic Screening: A Tool for Better Health with Age”. He showed that with more sensitive genetic screening techniques minor genetic changes can be detected. These are a lot more common than previously thought of. Matt Pratt-Hyatt, PhD is Associate Laboratory Director for the Great Plains Laboratory in Lenexa, KS.

Specifically, Dr. Pratt-Hyatt explained that single nucleotide polymorphisms, frequently called SNPs (pronounced “snips”) were the most common type of genetic variations among people. These genetic changes in the DNA often cause disease. Different types of genetic testing can identify the gene defects of SNPs. One of the questions is how aging can be better managed when genetic defects are known.

When it comes to our genetic material there are over 3 billion base pairs, all contained in 23 chromosomes. These are home to 20,000-25,000 genes, most of which are normal.

A gene has three regions all of which can have mutations. In the middle there is the coding region; one end is the regulatory region for transcription initiating; at the other end the transcription termination signals are located. Minor mutations in any of these regions can have major implications for the health of the individual or they can stay silent SNPs. SNPs are classified into missense mutation or nonsense mutation. This description just shows how intricate and complex the process of mutations can be!

Three types of sequencing are commonly used:

Three types of genetic screening for better health

  1. Sanger sequencing
 utilizes certain dyes that correspond to specific nucleotides of the DNA. The benefits of Sanger sequencing is that it can cover one gene completely. It can find previously unknown mutations. But the disadvantage of Sanger sequencing is that you cannot process a large number of genes.
  2. The Florophore-base detection looks at multiple SNPs in a single run. This method is cheaper than whole genome sequencing. But one of the disadvantages of Florophore-base detection
is that only a limited number of SNPs can be processed per run. It also can miss new mutations.
  3. Benefits of next generation sequencing 
are that it can look at 1000s of SNPs per run. It is much more accurate than previous technologies. A drawback
though is that the equipment is much more expensive.

Not all of these tests have to be done, but the physician can make the choice of the appropriate one for the patient. The following are some applications with regard to how genetic screening can be useful for better health.

Detoxification as part of genetic screening for better health

Since the 1970’s and 1980’s it has become clear that there are many steps in the detoxification process in the liver. It involves major enzyme systems that are controlled by the P450 genes. Several genetic defects are known that run in different families. These effects are very important for drug detoxification and metabolism. Any mutation in one of the P450 controlling genes will lead to accumulation of the drug that is normally detoxified by this enzyme system. As any drug has toxicity at higher levels, the consequence is possible toxicity, if the drug is not discontinued or lowered. When people age, they often have spontaneous mutations of the P450 detoxification system and this should be taken into account by doctors who prescribe medications. Common drugs that cause problems with the P450 controlled detoxification are antidepressants, the blood thinner Coumadin, the antibiotic erythromycin, the asthma medication Theophylline and many others.

Here is an example of how important this knowledge is in an elderly patient who was sent to the hospital with an irregular heartbeat. The electrocardiogram allowed a diagnosis of atrial fibrillation. The doctor treated the patient with a cautious loading dose of 0.5 mg of Coumadin in an attempt to thin the blood of the patient. This would prevent a blood clot or a stroke due to the arrhythmia. Normally a small dose like this would not do much in terms of blood thinning, as it would take several days of a low dose like this to achieve blood thinning. Unbeknown to the physician, this patient was different as he had a defect in the Cyp2c9 gene, a subtype of the P450 system. Very quickly the patient developed bleeding gums and bruising of the skin in various locations. When blood tests were taken, the INR, a measure of the clotting system, was 3.7, a value that should not have exceeded a level of 2 to 3. Genetic testing confirmed a homogenous mutation of the Cyp2c9 gene that explained the toxicity of Coumadin in this case, one of the many drugs that is detoxified by the P450 system.

Mental health as part of genetic screening for better health

Many mental illnesses can be caused by defects in various parts of the brain metabolism. This is particularly so when it involves the synthesis of brain hormones. If there are genetic defects, this can lead to the particular brain metabolism that is associated with depression or schizophrenia. Even dementia, Alzheimer’s disease and Parkinson’s disease can be caused by genetic defects. Methylation pathway defects are another source of possible genetic defects, which can affect multiple metabolic pathways. This is the cause of many diverse conditions like autism, diabetes and some hereditary cancers. The reason it is important to be aware of such genetic aberrations is that often vitamin B2, B6, niacin, vitamin B12 and the minerals magnesium and zinc can stabilize a person with methylation defects.

Cholesterol as part of genetic screening for better health

People with obesity have problems with their lipid metabolism, diabetes, high blood pressure and often heart disease and strokes. Changes in cholesterol metabolism are at the center of these problems. Cholesterol is one of the building blocks of cell membranes, and cholesterol is one of the normal components in the blood as long as the subfractions are properly balanced (LDL and the HDL cholesterol). Unfortunately many people have minor or major defects of the biosynthetic pathway of cholesterol. There are 5 genes involved in the acetyl CoA biosynthesis. 21 genes are involved in the main cholesterol biosynthesis pathways. Over 10 genes control cholesterol metabolites. Historically these genes were detected because of various familiar gene defects that caused problems with the biochemical processes surrounding cholesterol. Familial high cholesterol levels (familial hypercholesterolemia) is one of these common conditions.

Patients who have this condition will often have high cholesterol and also often have a family history of gall bladder surgery for gallstones and a history of premature heart attacks or strokes. Early diagnosis and careful clinical intervention can improve the outlook for many patients.

Genetic Screening For Better Health

Genetic Screening For Better Health

Conclusion

Not all genetic conditions can be helped by modern medicine. But many minor genetic abnormalities can be worked around or drug interactions can be avoided provided the genetic defect is known. It is encouraging that newer test methods have now shown success, as they are more affordable than in the past. As time progresses the price of these genetic tests will come down even further. Mental health, detoxification pathways and the metabolic syndrome of obesity are practical applications where genetic tests have significance.

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.
