Parkinson’s Disease May Be Stopped

Parkinson’s disease is common in the US; new research shows that the use of an old anti-depression medication can stopParkinson’s disease The use of nortriptyline, a 50-year old antidepressant has shown to normalize a nerve cell protein. In rats nortriptyline dissolved toxic alpha-synuclein clusters in brain cells. These toxic protein clusters seem to be happening in the brain of Parkinson’s disease patients also. It is the protein by the name of alpha-synuclein that research first found in rats to cause the toxic protein clusters in nerve cells of the substantia nigra, a part of the brain stem.

But nortriptyline was able to normalize the concentration of the protein. In preliminary studies in humans the investigators found that there was a significant improvement of Parkinson’s disease with the use of nortriptyline.

Placebo controlled trial with nortriptyline

Now a research team from Michigan State University in Grand Rapids conducted a larger clinical placebo-controlled trial. The lead researcher Collier of the study group found that Parkinson’s patients who received treatment for depression with the tricyclic agent nortriptyline needed less dopamine, the main drug used to treat Parkinson’s disease. This indicated to the researchers that nortriptyline was preserving brain cells that were still making their own dopamine. In rat experiments they could show that it was the dissolving of toxic alpha-synuclein proteins by nortriptyline that was the key to therapeutic success.

Lisa Lapidus, a co-worker on the Michigan State University research team summed up their research: “What we’ve essentially shown is that we are dealing with a drug that the FDA approved already 50 years ago. Patients tolerate the medication relatively well. This could be a much simpler approach to treating the disease itself, not just the symptoms.”

Parkinson’s disease may be stopped also by old diabetes drug

Thomas Foltynie found that the diabetes drug exenatide helps patients with Parkinson’s disease. Dr. Foltynie is a professor of neurology at the University College London and co-author of the study.

Exenatide is an injection drug. When preliminary studies showed that this drug was effective in helping Parkinson’s disease patients lose their problems with walking and balance, a formal study followed.

Professor Foltynie designed a study where 60 people with Parkinson’s disease either got injections of exenatide or placebo injections. Patient exams followed regarding their musculoskeletal system and balance at baseline and every 12 weeks. A score system of 132 points assessed their Parkinson’s disease. After 48 weeks those who had been taking exenatide had a gain of 1 point on that scale while the placebo group dropped 3 points. After 48 weeks the drug administration (exenatide) finished. But after another 12 weeks another scoring and assessment of the Parkinson’s disease symptoms took place. The experimental group on exenatide scored 3.5 points higher than the placebo group. This suggests that exenatide is helping to treat the cause of Parkinson’s disease, not just the symptoms.

Parkinson’s disease may also stop through the use of caffeine

Parkinson’s disease was in the news again because of another study that involved breaking up misfolded alpha-synuclein through caffeine.

Misfolded alpha synuclein forms clumps inside dopamine producing cells in the substantia nigra of the brain stem. Misfolded alpha synuclein acts like a toxin to the dopamine producing cells and eventually these cells die off. This is the brain region that is responsible for making muscle movements smooth and stabilizes balance. The cells that have misfolded alpha synuclein clumps in them also go under the name of “Lewy bodies”.

Dr. Jeremy Lee from the University of Saskatchewan (Saskatoon, Saskatchewan, Canada) has isolated two compounds from coffee. They are called C8-6-I and C8-6-N. They can bind to alpha-synuclein and prevent clumping, which stops the toxic effects on dopamine producing nerve cells. Like with nortriptyline the caffeine effect is a curative approach to Parkinson’s disease.

Parkinson’s Disease May Be Stopped

Conclusion

There is a new therapeutic approach to Parkinson’s disease. Researchers have detected a protein called alpha-synuclein to cause toxic protein clusters in nerve cells of the substantia nigra, a part of the brain stem. When these cells die from the accumulation of these misfolded proteins, patients come down with Parkinson’s disease. But three different methods of treatment can improve Parkinson’s disease by dissolving the protein alpha-synuclein.

  1. Nortriptyline was able to normalize the concentration of the protein. In preliminary studies in humans the investigators found that there was a significant improvement of Parkinson’s disease with the use of nortriptyline.
  2. Exenatide, an injection drug for diabetes, has been described to help Parkinson’s patients get better.
  3. Caffeine can also dissolve misfolded alpha synuclein (two compounds from coffee called C8-6-I and C8-6-N). This helps patients with Parkinson’s disease to stabilize.

This is only the beginning of a new approach to Parkinson’s disease and an attempt to cure the disease by dissolving the underlying mechanism. So far the drugs that are in use for Parkinson’s disease are only attempting to stimulate dopamine producing nerve cells to produce more dopamine. But the underlying pathology of accumulating misfolded alpha-synuclein clumps is not yet in the treatment protocol. The new research is different, as it takes this into account in an attempt to prevent the condition.

Close Diabetes Control Prolongs Life

 

A 20-year study showed that close diabetes control prolongs life. A study divided 160 people with diabetes into two groups. The one group continued to get standard care. Yet the other group received a multi targeted, aggressive treatment protocol. As a result after 20 years the group with the intensive treatment protocol lived 7.9 years longer than the group with the standard treatment.

Dr. Oluf Pederson was the senior investigator of the physician team that followed the diabetes group. He said that they concentrated on a number of known adverse factors and treated them aggressively. These factors were first of all high blood glucose values and clotting risks, also high blood pressure and high triglycerides and in addition cholesterol values. Behavior modification was the therapeutic method to get people with risk factors to exercise more, adopt a healthy diet and stop smoking. Medication in select cases also played a role.

More details about the study

The intervention of intensive treatment lasted 8 years. After that the patients were still in a follow-up study for 13 years. At the beginning of the study patients were on average 55 years old and were borderline obese.

The investigation team screened for complications of diabetes. This included screening for kidney disease, heart disease and blindness. Dr. Joel Zonszein, the director of the New York Clinical Diabetes Center at Montefiore Medical Center said: ”These results are impressive and most patients do not receive the correct treatment, according to national surveys.”

Other studies about diabetes  

Foreign studies

Study from Croatia
  • Another study from Croatia involved 200 patients. It concentrated on patients who did not respond to metformin. Physicians used alternative treatment modalities, and they observed and measured blood sugars and hemoglobin A1C in the following 6 months. The study concluded that those patients who received aggressive treatment of their condition did better than those who did not receive the same vigorous approach.
Study from Japan
  • This Japanese study documented that female patients with type-2 diabetes developed kidney damage earlier than their male counterparts.  Consequently, the investigators pointed out how important it is to treat diabetes aggressively to avoid kidney damage.
Study from Singapore
  • This 2016 study from Singapore analyzed retroactively the impact of diabetes on the long-term survival after coronary bypass grafting (CABG).  5720 consecutive patients had their isolated first CABG surgery between 1982 and 1999. The mean follow-up was 13 years. 34.6% of the patients had diabetes, 51% had high blood pressure and 46.6% had elevated blood lipids. The initial mortality after the CABG surgery was 2.4% in the diabetic group and 1.8% in the non-diabetic group. 20-year survival rates following CABG surgery were 30.9% in diabetics and 49.2% in the non-diabetics, an 18.3% difference. The 20-year freedom from cardiac mortality rates was 56% in diabetics and 68.4% in non-diabetics. Other risk factors that led to cardiac mortality were the following: female gender (1.43-fold risk), diabetes (1.51-fold risk), previous heart attack (1.54-fold risk) and a low left ventricular ejection fraction of less than 35% (2.6-fold risk). The conclusion from this study was that long-term survival in diabetics following CABG surgery was much lower than that of non-diabetic controls. Hence the key to improving long-term survival for diabetics is to treat comorbidities like high blood pressure and elevated lipids aggressively as well as getting blood sugars and hemoglobin A1C values under control.

US studies

  • In this US study 558 youth (age less than 21) between February 2012 to July 2015 received follow-up. Between 40% and 50% of these diabetics needed insulin to improve their diabetes. Unfortunately their diabetes showed poor control, as their high hemoglobin A1C values indicated. Median HbA1C was 6.7%, 8.5%, 9.6%, and 9.7% in those with disease duration less than 1 year, 1-2 years, 2-3 years and less than 4  In other words, the longer the young patients had diabetes, the less seriously they took their treatment. Only 33% treated their high blood pressure and only 11% their elevated blood lipids. Microalbuminuria, an indicator of diabetic kidney disease, and non-alcoholic fatty liver disease were present in 5% to 6% of these young diabetic patients. The authors came to the conclusion that there were serious gaps in treating these young diabetics. Further follow-up data of the same group of patients in the coming years will provide further data. In conclusion, the new hemoglobin A1C ranges of 3.8% to 4.9% as the new normal range explains why these youths who do not treat their diabetes properly are at high risk to develop complications from their poorly controlled diabetes.
Heart attacks and erectile dysfunction
  • Heart attacks are more common among patients with uncontrolled diabetes. This US study classified diabetics according to the tightness of their diabetes control. Researchers found examining 606 men and 606 women with diabetes that they could reduce their risk of a heart attack, if they controlled smoking, glycated hemoglobin (hemoglobin A1C), systolic blood pressure, and total and high-density lipoprotein cholesterol. The control of all these risk factors could contribute to the prevention of heart attacks. 35% of men and 45% of women could prevent having a heart attack. A laxer control still would prevent 36% of heart attacks in men and 38% in women. A very aggressive diabetes control could prevent 51% of heart attacks in men and 61% in women. Most noteworthy: close diabetes control prolongs life.
  • Erectile dysfunction (ED) is a big problem among diabetic men. This study from Seattle shows the investigation of 136, 306 men with erectile dysfunction. 19, 236 of these men had diabetes prior to their ED problem. Over a two-year observation period diabetic men had much worse ED problems. As a result they needed to receive secondary line treatments  like penile suppositories or injectables. Others needed tertiary treatments like penile prostheses. In those whose diabetes control was good, oral agents as first-line therapies were usually sufficient.
More studies about risks and benefits of lifestyle
  • Middle-aged women with diabetes have a 4- to 5-fold higher risk for developing heart attacks while men do not show such a higher risk. It is probably particularly important for women to control diabetes when they are diagnosed with it to reduce the risk of coming down with a heart attack.
  • In 2011 Taylor from Newcastle University showed in a group of diabetes patients that he could cure diabetes permanently with an extremely low calorie diet. The trial was simple: he took overweight or obese patients with diabetes and put them on a starvation diet of 600-700 calories per day for 8 weeks. Consequently 43% of diabetic patients received a permanent cure of their diabetes. More info: http://nethealthbook.com/news/cure-diabetes-permanently/

 

Close Diabetes Control Prolongs Life

Close Diabetes Control Prolongs Life

Conclusion

The new hemoglobin A1C ranges that are desirable are between 3.8% to 4.9%. When diabetics bring their hemoglobin A1C level into this range, they do not get complications from their previously poorly controlled diabetes. Close diabetes control prolongs life. But as can be seen from a brief review of the literature physicians tend to be lax, patients are lax, and diabetes is often not well controlled. This leads to erectile dysfunction in males, to heart attacks and kidney failure in both sexes. Blindness and painful diabetic neuropathy are also common complications of poorly controlled diabetes. Amputations from clogged arteries are also among the complications. “Close diabetes control prolongs life” is the new mantra that everybody with diabetes needs to follow.

Lifestyle changes control diabetes and prolong life

As stated above Dr. Taylor from Great Britain has shown that a brief 600 to 700 calorie diet can cure 43% of diabetic patients permanently. Quit smoking, bring the glycated hemoglobin (hemoglobin A1C) into the normal range, control your systolic blood pressure as well as your total and high-density lipoprotein cholesterol. Do all these things, exercise regularly, and your diabetes will be well controlled. Remember: close diabetes control prolongs life!

Healthy Oils For A Healthy Body

Healthy oils for a healthy body? Quite frequently the news are full of articles that want to inform you what fat or oil to eat. At the end the consumer often faces information overload and confusion.

Here I am reviewing what we know about the various oils.

1. Coconut oil not as good as it was thought

This review article pointed out that coconut oil does elevate the bad cholesterol, called LDL cholesterol. This is not a desirable effect, as it can lead to heart disease and possibly heart attacks. On the other hand coconut oil also elevates HDL cholesterol, the good cholesterol that mobilizes LDL cholesterol. The article points out that coconut oil may be a better choice than butter. Butter does not elevate HDL cholesterol to offset the effects of LDL cholesterol. Researchers felt that the occasional use of coconut oil instead of butter would be justifiable. But they advised strongly against the daily use of coconut oil. Instead they recommended olive oil, canola or soybean oil, along with nuts and seeds, as your primary fats. I agree with olive oil, but have concerns about canola or soybean oil, as I explain it later in this article.

Dr. Andrew Weil reviewed coconut oil in Self Healing August 2014. He said that the effect on cardiovascular health remains largely unclear. He is not aware of any “study that has shown using coconut oil leads to significant weight loss”. It is basically a thumbs down assessment for coconut oil. You may want to use it occasionally for baking or a special Thai food meal.

Let’s remember that the long-lived populations such as in Okinawa and others never used coconut oil.

2. Polyunsaturated fatty acids used in processed food

news release in 2016 describes new FDA food guidelines. They recommend that saturated fat should not exceed 10% of the total daily caloric intake, but there are still different opinions: some studies show that saturated fat may not be responsible for hardening of the arteries. Other studies have shown that breast cancer is more common in persons who consume more saturated fat .

In the 1980’s the news came out that saturated fats would be bad for arteries. At that time there was a switch to polyunsaturated fatty acids. These consist of safflower oil, canola oil, sunflower seed oil, corn oil, soybean oil and grape seed oil.

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

In contrast olive oil is a much more stable oil. And long-lived populations in the Mediterranean seem to be the proof, that it is a healthy fat source for them and for us.

Personally I have cut out polyunsaturated fatty acids out of my food and I suggest you do the same. We know now that polyunsaturated fatty acids lead to inflammation via the arachidonic acid pathway. This can cause gout, arthritis, diabetes, and inflammation of the arteries with subsequent clots causing heart attacks and strokes. I don’t need all of these diseases, I am doing fine without polyunsaturated fatty acids.

3. Omega-6 to omega-3 ratio

The cell membrane consists of two lipid layers at a specific ratio of omega-6 essential fatty acids and omega-3 essential fatty acids. It also contains triglycerides, phospholipids and protein. Safflower oil, canola oil, sunflower seed oil, corn oil, soybean oil and grape seed oil are mostly omega-6 fatty acids and the type of polyunsaturated fatty acids that prevail in processed foods. With the consumption of too much processed food the body has a problem constructing cell membranes. As you can see by this link when you compare the metabolism of omega-6 fatty acids with that of omega-3 fatty acids, there is a fundamental difference. The linoleic acid of omega-6 fatty acids metabolizes into arachidonic acid, which causes pro-inflammatory mediators, PGE2 and LTB4. On the other hand with omega-3 fatty acids alpha-linolenic acid (ALA) is metabolized into EPA, DHA and the anti-inflammatory mediators PGE3 and LTB5.

Disbalanced omega-6 to omega-3 ratio

It is easy to understand why a surplus of omega-6 fatty acids from processed foods will disbalance 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. Be particularly careful in avoiding soybean oil, which is the most popular oil in the last few decades to foul up the omega-6 to omega-3 ratio through processed foods. Read labels to avoid soybean oil and other omega-6 fatty acids.

When it comes to balancing omega-3 and omega-6 fatty acids in your diet, be aware that nutritional balancing can help you restore the ideal omega-6 to omega-3 ratio of 1:1 to 3:1. An easy way is to simply cut out processed foods as much as possible. Supplement with molecularly distilled fish oil capsules to add more omega-3 fatty acids into your food intake.

4. Fish oil

What we learned from this is the importance of fish oil as a supply of omega-3 fatty acids. But nuts also supply us with omega-3 fatty acids. Eating fish three times per week is another way to get enough fish oil on board. There is a word of caution. Our oceans are so contaminated with mercury that you want to be careful and eat only fish low in mercury content. Avoid swordfish, tuna fish or grouper.

But wild salmon and mackerel are fish low in mercury and safe to eat. I would recommend that you eat seafood at least three times per week to have a good source of omega-3 fatty acid. In addition I would also recommend you take omega-3 supplements. I take it in the form of molecularly distilled high potency omega-3. I take 2 capsules twice a day. In addition I take 750 mg of krill oil once per day, another source of molecularly distilled marine omega-3 supplement.

5. Cold pressed virgin olive oil

Organic olive oil contains monounsaturated fatty acids that are neutral in terms of effects on the cardiovascular system. But it also contains a lot of polyphenols and among these in particular hydroxytyrosol that lower blood pressure and protects you from hardening of the arteries. This likely is the main reason why the Mediterranean diet is so healthy, apart from its emphasis on vegetables, which further makes it desirable. In a 2012 study from Spain it was found that mortality from heart attacks was 44% lower than that of a control group who did not incorporate olive oil in their diet.

Only two tablespoons of virgin olive oil per day protect you from heart disease. It does so by reducing the total cholesterol level in the blood as well as the LDL cholesterol level. At the same time the more polyphenol is contained in olive oil (such as in extra virgin olive oil), the more HDL your body will produce, which is essential to extract oxidized LDL from arterial plaque. On top of that polyphenol rich olive oil will increase the size of the HDL particles (these larger particles are called HDL2), which are more efficient in extracting oxidized LDL from arterial plaque.

Effects of olive oil

Olive oil has been shown to lower blood pressure and prevents heart attacks and strokes.

Sept. 2014 study in humans showed that higher polyphenol olive oil as found in extra virgin olive oil caused an increase in the more effective HDL2 particles, which cleans out plaque from arteries more efficiently than the regular, cheaper olive oil. You should use mainly olive oil for your regular cooking. Cold pressed, virgin olive oil is more expensive than the regular olive oil, but this is what has been proven to enhance health and to prolong life, if you consume it regularly.

Healthy Oils For A Healthy Body

Healthy Oils For A Healthy Body

Conclusion

Sometimes it is useful to think about what fats you are consuming. We tend to eat too many omega-6 fatty acids from processed foods. These are polyunsaturated fatty acids found in safflower oil, canola oil, sunflower seed oil, corn oil, soybean oil and grape seed oil. Food merchants use these polyunsaturated fatty acids to have a longer shelf life of their products. But the more omega-6 fatty acids we consume, the higher the omega-6 to omega-3 ratio gets. This leads to inflammation in the body and the arteries. It causes heart attacks, strokes and other illnesses. Years ago I cut polyunsaturated fatty acids out of my food intake. Instead I use organic cold pressed extra virgin olive oil. It is full of polyphenols (and among these in particular hydroxytyrosol). It lowers blood pressure and prevents heart attacks and strokes. I am not convinced that the hype around coconut oil can be verified. At this point I would suggest only occasional use of it.

You need to eat fish three times per week and other seafood as a source of omega-3 fatty acids. This is important to keep your omega-6 to omega-3 ratio well balanced. I also take fish oil supplements regularly like krill oil once daily and fish oil capsules twice a day. You can buy these molecularly distilled to ensure they are mercury contamination free.

Young Heart Stem Cells Can Cure Old Hearts

Young heart stem cells can cure old hearts in rats. This is what research at the Cedars-Sinai Heart Institute in Los Angeles found. You may not be that impressed, because this talks about rats and not humans. But this is a brand-new concept, so of course research of animal experiments is first.

The heart experiment

Dr. Eduardo Marbán, MD, PhD, is the research director of the Cedars-Sinai Heart Institute. His idea was to take cardiac stem cells (called cardiosphere-derived cells) from hearts of newborn rats. He injected them into 22 months old rats. The human equivalent for 22 months old rats are older people with older hearts. Within one months of the stem cells’ injections the older rats had normal functioning hearts. Their telomeres were also normal. Telomeres are the caps of the chromosomes of the heart cells. The researchers were astonished to find that the previously short telomeres had become longer. This happened within only one month of the stem cell injections. To Marbán’s surprise the older rats also grew hair faster and gained 20% of their previous exercise tolerance limit. In other words, the injection of heart stem cells had rejuvenated the old rats.

Dr. Marbán has previously shown that exosomes play an important role with stem cell regeneration of old heart cells. These particles from the stem cell donor contain RNA and other growth factors.

Overview of how stem cells can reverse heart failure

Cardiovascular disease includes high blood pressure, coronary artery disease, stroke and congestive heart failure. About 2600 Americans die from cardiovascular disease each day in the US. This is roughly one death every 34 seconds. With old age, if a heart attack does not kill you, congestive heart failure will. With heart failure your heart ceases to pump enough blood through your system. Nutrients and oxygen need to reach all of our cells or it means death for the patient. With the knowledge of this serious background, stem cells have come into the focus in an attempt to combat congestive heart failure.

Animal experiments with stem cells in mice, rats and pigs have shown some progress in restoring better heart function. Researchers used different sources of stem cells, like cardiac stem cells that reside in the heart muscle itself. They also used other stem cell sources. Among these were myoblasts (from muscle), mesenchymal stem cells (from fat tissue) and bone marrow stem cells. Several smaller human trials showed that improvement of heart function was possible following a heart attack. In the procedure the surgeon opened coronary arteries and injected stem cells into the affected damaged heart muscle. How can we assess the result of a successful stem cell treatment? By measuring the left ventricular ejection fraction. This means that the heart can deliver a larger volume of blood every minute. The heart pumps more blood from the left ventricle with each heartbeat than before the treatment.

Other experiments that rejuvenate tissues of older animals

Another line of experiments in this paper shows that certain growth factors are necessary to activate stem cells.

  1. One experiment from the 1950’s describes the stitching together of the skin on their flanks joined an old and a young rat. After this procedure the blood vessels grew and joined the two animals circulatory systems. The older animals knee cartilage damage was no longer there, as the cells from the young animals’ blood had healed the damage.
  2. Research had no knowledge of this fact at that time. But another research group in the 2000’s repeated the experiment and could prove that the stem cells of the young animals activated the growth factors in the old animals.
  3. In 2004 Dr. Rando noted that muscle cells of aging mice were aging because of a lack of stimulation of the local skeletal muscle stem cells. These are satellite cells. Experiments similar to the rat experiment showed that there were factors in the blood of young mice that could re-activate stem cells in the muscles of old mice. Agility and movement of the older mice improved. The improvement in the older mice with knee arthritis disappearing and liver cells rejuvenating was astounding.

More evidence that rejuvenation of heart cells is possible

  1. Amy J. Wagers, a former colleague of Dr. Rando carried on experiments with respect to rejuvenation of hearts in mice. She and her colleagues found what stimulated the hearts of old mice. It was a protein called GDF11 (from young mice).  This 2016 publication describes the action of GDF11.
  2. A 2014 paper describes that GDF11 was able to restore aging muscles to a youthful state. But the researchers were also able to rejuvenate stem cell function in general with GDF11.
  3. Another paper describes that blood from young mice stimulates the brain of older animals to achieve rejuvenation. It is the protein of the young stem cells (called GDF11) and possibly other growth factors to bring about this rejuvenation. It works not only on heart cells, but also on hippocampus tissue in dementia models. This may be important in humans for treatment of Alzheimer’s disease.

“We can turn back the clock instead of slowing the clock down.” Dr. Toren Finkel said. He is the director of the Center for Molecular Medicine at the National Heart, Lung and Blood Institute. He went on to say: “That’s a nice thought, if it pans out.” But others who caution that overstimulation of stem cells could cause cancers say: “It is quite possible that it will dramatically increase the incidence of cancer,” Dr. Irina M. Conboy said, a professor of bioengineering at the University of California, Berkeley. “You have to be careful about overselling it.”

Degenerative changes in humans responding to stem cells

Many degenerative changes in humans respond to stem cell treatments. Are there stem cells present in degenerative tissue in humans similar to the animal experiments described above? Are the stem cells merely providing growth factors so the dormant stem cells jump into action and regenerate? Could it be that in future therapists could give a certain growth factor mix  intravenously to a patient, and the same effect as stem cell injections would be posssible? These are all unanswered questions, but research in the next decade should answer at least some of those questions.

Growth hormone improving heart function in heart failure patients

In 2008 a metaanalysis of human studies of congestive heart failure and treatment with human growth hormone (HGH) injections was a research topic. It showed an average increase of the ejection fraction by 4.3%. There were also increased cardiac output, decreased systemic vascular resistance and improved hemodynamic effects. The question is whether the effect is a direct effect on the heart muscle cells by HGH or whether HGH was recruiting dormant heart muscle stem cells. This is not clear at this point.

Young Heart Stem Cells Can Cure Old Hearts

Young Heart Stem Cells Can Cure Old Hearts

Conclusion

We have entered an exciting period of medical research. Although there is only a record of many animal experiments, there is overwhelming evidence that the same principles are true in humans. Many stem cell protocols for humans have already seen use for various applications. But stem cell treatments for heart disease are still in their early stages. As it becomes obvious from my review of this topic, some patients who were part of clinical trials have already experienced positive results. Congestive heart failure or poor pump performance following a heart attack have improved following various stem cell procedures. In the next few years there likely will be a proliferation of treatment options for patients. Although some critics have pointed out a possibility of cancer developing as a side effect of stem cell treatment, no evidence is noticeable at this point.

Resveratrol Effective In Humans

Resveratrol has been labeled a powerful antioxidant; but is resveratrol effective in humans?

  1. Quack watch says: don’t buy into the hype that resveratrol is effective in humans.
  2. WebMD claims that there would not be enough medical evidence to say that the average person should supplement with resveratrol to receive benefits.

Despite these recommendations the following evidence supports that resveratrol is indeed effective in humans.

Resveratrol effective in humans: high blood pressure patients

A 2017 study of high blood pressure patients examined resveratrol supplementation with two groups, 46 stage 1 hypertension patients and 51 stage 2 hypertension patients. Stage I hypertension had a systolic blood pressure of 140–159 mmHg and a diastolic blood pressure of 90–99 mmHg. Stage 2 hypertension was defined as a systolic blood pressure of 160–179 mmHg and a diastolic blood pressure of 100–109 mmHg. Each subgroup was divided into two groups, one receiving regular antihypertensive medication, and the other group receiving regular antihypertensive medication plus Evelor. Evelor is a micronized formulation of resveratrol. The trial lasted two years. The purpose of the trial was to determine the effect of resveratrol, which was added to the regular antihypertensive medication (or not) to see whether it had blood pressure lowering effects. The interesting result showed that the resveratrol addition was sufficient to bring the blood pressure down to normal levels with only one antihypertensive drug. The control group without resveratrol needed two or three drugs to get the blood pressure under control. In addition, liver function tests showed that resveratrol normalized negative side effects of the antihypertensive drug on the liver. Both liver enzymes, glutamate-pyruvate transaminase (SGPT) and gamma-glutamyl transferase (Gamma-GT) were normal in the group where resveratrol had been added.

Resveratrol effective in humans: diabetes patients

Resveratrol helps diabetes patients. Resveratrol, the bioflavonoid from red  wine is a powerful anti-inflammatory. This antioxidant has several other effects, which make it challenging to measure each effect by itself. This group of investigators managed to simultaneously measure these effects. They found that resveratrol lowered the C-reactive protein by 26% and tumor necrosis factor-alpha by 19.8%. Resveratrol also decreased fasting blood sugar and insulin; in addition it reduced hemoglobin A1C and insulin resistance. The recommended daily dose of resveratrol was 1000 to 5000 mg.

Resveratrol effective in humans: improves bone density

Resveratrol improves bone density in men: 66 middle-aged obese men with an average age of 49.3 years and a mean body mass index of 33.7 were recruited for this randomized, double blind, placebo-controlled trial. The purpose was to study whether there would be changes in bone turnover markers (LDH, an enzyme involved in bone turnover), but also whether bone mineral density (BMD) would increase. Resveratrol was given to a high group (1000 mg per day), a low group (150 mg) and a placebo (fake pills) were given to the third group. The end point was an elevation of the bone alkaline phosphatase (BAP). This was measured in the beginning of the study and at 4, 8 and 16 weeks. The high group of resveratrol had a 16% increase of the BAP throughout the study and a 2.6% in lumbar spine bone density (measured by a trabecular volumetric method). The low resveratrol group showed no bone restoring effect. MJ Ornstrup, MD, the lead investigator said that this was the first time that a clinical team has proven that resveratrol can potentially be used as an anti-osteoporosis drug in humans. She added that resveratrol appears to stimulate bone-forming cells within the body.

Resveratrol effective in humans: anti-aging effects

The Nurses’ Health Study showed that both a Mediterranean diet and resveratrol can elongate telomeres.

The fact that you can have a longer life with a Mediterranean diet is known for some time. But now a study has shown that the reason for a longer life is the fact that telomeres get elongated from the Mediterranean diet. Telomeres are the caps at the end of chromosomes, and they get shorter with each cell division. This is the normal aging process.

The finding of elongated telomeres comes from the ongoing Nurses’ Health Study that started enrolling subjects in 1976. At that time 121 700 nurses from 11states enrolled in the study. In 1980 diet sheets were used to determine who was adhering to a Mediterranean diet. 4676 middle-aged participants were identified to qualify for this study. This diet consists of a combination of vegetables, legumes, fruits, nuts, grains and olive oil. Fish and lean meats were also consumed. The control group followed a regular diet. Between 1989 and 1990 blood tests were obtained to measure telomere length in white blood cells. It is known that smoking, stress and inflammation shortens telomeres. The lead author Marta Crous-Bou stated that overall healthy eating was associated with longer telomeres compared to the control group. But the strongest association was found in women who adhered to the Mediterranean diet when compared to the controls. For the best diet adherence score there was a 4.5 year longer life expectancy due to slowed telomere shortening.

Longer telomeres have been found to be associated with the lowest risk to develop chronic diseases and the highest probability of an increased life span. I have reviewed the importance of lifestyle factors in this blog where I pointed out that Dr. Chang found a whole host of factors that can elongate telomeres by stimulating telomerase. It has been shown in humans that increased physical activity elongated telomeres. So did vitamin C, E and vitamin D3 supplementation, resveratrol, a Mediterranean diet and marine omega-3 fatty acid supplementation. In addition higher fiber intake, bioidentical estrogen and progesterone replacement in aging women and testosterone in aging men, as well as relaxation techniques like yoga and meditation are also elongating telomeres.

Aging is due to shortening of telomeres. Elongation of telomeres by resveratrol leads to prolonged life (or anti-aging).

Resveratrol effective in humans: resveratrol and cancer

As this overview shows, it seems that several mechanisms of action give resveratrol the power to be an anticancer agent. Resveratrol is anti-proliferative and has anti-angiogenesis mechanisms. In addition resveratrol stimulates apoptosis, which is programmed cell death. All these actions together help resveratrol to have anticancer properties. Resveratrol can also be used in combination with other cancer treatments, which improves survival figures. As the link above explains, more cancer clinical trials with a variety of cancers and larger patient numbers are required, but many smaller clinical trials have already been very successful showing efficacy of resveratrol as a chemotherapeutic agent.

In this 2015 publication about malignancies and resveratrol an overview is given about the use of resveratrol and cancer treatment. It summarizes that the development of cancer is a multifactorial process that involves the 3 stages of initiation, promotion and progression. One of the cancer promoting factors is chronic inflammation. Resveratrol has been shown to be anti-inflammatory. At this point it is not clear how the animal experiments will translate into the human situation. More clinical observations are necessary.

Resveratrol effective in humans: cardiovascular disease

Resveratrol has beneficial effects on preventing hardening of the arteries, diabetes, various cancers and inflammatory conditions like Crohn’s disease and arthritis. As this link explains resveratrol also stimulates the antiaging gene SIRT1 by 13-fold. This confirms the anti-aging effect of resveratrol. This 2012 study has also confirmed that resveratrol from red wine is what is responsible for the “French paradox” (longer life expectancy despite high saturated fat intake).

Resveratrol effective in humans: polycystic ovarian syndrome 

Polycystic ovarian syndrome could be significantly healed with resveratrol in a randomized, double blind, placebo-controlled trial. It involved 30 subjects who completed the trial. 1500 mg of resveratrol or placebo were administered daily for 3 months. Serum total testosterone was decreased by 23.1% at the end of 3 months in the experimental group versus the placebo group. There was also a decrease of dehydroepiandrosterone sulfate of 22.2%. Fasting insulin level was reduced by 31.8%. At the same time insulin sensitivity was increased by 66.3%. The authors concluded that resveratrol had significantly reduced ovarian and adrenal gland male hormones (androgens). This may be in part from the drop in insulin levels and the increase of insulin sensitivity.

Resveratrol effective in humans: anti-arteriosclerotic effects in diabetics

A double blind, randomized, placebo-controlled study was done on 50 diabetics. The cardio-ankle vascular index (CAVI) was used to determine arterial stiffness. The purpose of this study was to determine the effect of resveratrol on the stiffness of arteries in a group of diabetics and compare this to a placebo. Diabetics are known to have premature hardening of the arteries (arteriosclerotic changes). After 12 weeks of taking 100 mg of resveratrol per day there was a significant reduction in arterial stiffness in the experimental group, but not in the placebo group. Blood pressure also decreased by 5 mm mercury (systolic) in the experimental group.

Resveratrol effective in humans: ulcerative colitis patients

56 patients with mild to moderate ulcerative colitis received 500 mg of resveratrol or placebo and were observed for 6 weeks. This was a randomized, double blind, placebo-controlled pilot study. Bowel disease questionnaires were used to assess the bowel disease activity before and after the treatment. The resveratrol group decreased the disease activity significantly, but it also increased their quality of life. Blood tests showed that this improvement occurred as a result of reducing oxidative stress by resveratrol.

Resveratrol effective in humans: Alzheimer’s disease prevention

Here is a study where 52 Alzheimer’s patients were divided into two groups; one group was given 200 mg of resveratrol for a number of weeks, the other group placebo pills. There was a significant improvement in memory tests in the resveratrol group and functional MRI scans showed better functional connectivity in the hippocampi of the subjects. It is known that the hippocampus is the seat for short-term memory, which is lost in Alzheimer’s patients.

Conclusion

Resveratrol has a long history of showing evidence of improving health. It does so by countering oxidation of LDL cholesterol, which lessens hardening of arteries. This prevents heart attacks and strokes. Resveratrol is also a powerful anti-inflammatory, which helps patients with diabetes, with Crohn’s disease and arthritis. There is even a cancer preventing effect of resveratrol because of anti-proliferative and anti-angiogenesis effects as well as stimulating apoptosis. Because of these combined anticancer properties resveratrol is a chemotherapeutic agent that can be combined with conventional anticancer drugs.

There are enough randomized, double blind, placebo-controlled trials in humans to show that resveratrol is effective in preventing and treating several disease conditions. The medical establishment claims that there would not be enough medical evidence to say that the average person should supplement with resveratrol to receive health benefits. After my review outlined above I come to the opposite conclusion. It is quite clear that resveratrol has several important healing properties. It can improve diabetes; prevent hardening of arteries, lower blood pressure, attack osteoporosis and prevent Alzheimer’s disease. I have been taking 500 mg of resveratrol daily for years. It has not harmed me.
