Polyphenols or phytochemicals found in green tea can help fight off bad cholesterol and harmful sugar-derived substances through strong antioxidant activity in the body.

In a recent scientific research published in the journal Food Chemistry in Taiwan, it was found that the compound EGCG or epigallocatechin 3 gallate can help reduce low-density lipoproteins (LDL) or bad cholesterol and also prevents glycatin of blood sugar. Glycation is a process whereby sugar molecules are able to bind with other types of molecules such as protein.  Glycation is characteristic of conditions such as type 2 diabetes or adult onset diabetes.

To mimic actual conditions in the human body, the in-vitro study simulated in-vivo conditions by using human blood serum.

According to the researchers Chi-Hao Wu, Chi-Tai Yey and Gow-Chin Yen, the resistance of bad cholesterol to anti-oxidant activity was directly countered by the introduction of polyphenols found in green tea.  EGCG was also able to inhibit glycation in the same in-vitro studies.

Based on this research, the researchers stated that modest health benefits related to heart health and diabetes can be acquired through regular drinking of green tea.

Benefits of drinking green tea

And there are other reasons to love green tea:

1. Due to its antioxidant properties, green tea has been viewed in the world of alternative medicine and naturopathy as a natural cancer preventive both in men and women.

2. Reducing oxidative stress can also help reduce pain, which is why drinking green tea can also help people with chronic conditions such as arthritis and rheumatism.

3. There has been some evidence that green tea can help reduce the incidence of heart diseases by lowering bad cholesterol.

4. Increasing the amount of antioxidants in the body can boost the immune function, which effectively reduces “sick days” and helps the body bounce back from illnesses such as the common flu or the common cold.

5. In a study published in the American Journal of Clinical Nutrition, it was found that people who took green tea with beverages along with modest amounts of caffeine tend to burn more calories than those who don’t drink such beverages.

6. Green tea has antibacterial activity, which may help fight off cavities and tooth decay.

7. A study in Japan showed that people who regularly drank tea were at less risk for cancer and heart problems.

8. Green tea is a natural healing aid for people with multiple sclerosis.

9. Green tea has also been noted as a potential ally against Parkinson’s disease.  Antioxidants help prevent the brain from suffering from too much oxidative stress.

10. Green tea can help regulate the natural fluid balance of the body.

11. This beverage can also help reduce the incidence of allergies because it is capable of blocking allergy receptors, like a natural anti-allergy medication.

12. Green tea can help people lose weight by stimulating the body’s metabolism.

Resveratrol may be helpful in reducing the growth of prostate cancer cells and also provides a myriad of other health benefits.

According to the US Agricultural Research Service, the compound responsible for the so called “French Paradox” is proving to be a potent weapon against one of the deadliest killers around – prostate cancer.

The statement from the US ARS came about because of a study that was published in the medical journal Carcinogenesis. In the said study, in-vitro testing showed that prostate cancer cells actually died when they were exposed to the potent compound, resveratrol.

Throwing caution into the air

While it was true that cancer cell inhibition took place when the prostate cancer cells were exposed to the compound, it also increased the growth of blood vessels after the initial death of cancer cells, according to Thomas Wang, a researcher working for the Diet, Genomics and Immunology Laboratory of the US ARS.

The growth of extra blood vessels in the site of the prostate cancer was observed in laboratory animals who were genetically prone to developing prostate cancer.  Each of the animal subjects had been given 3 to 6 milligrams of the potent compound, which was equivalent to the amount of resveratrol found in six glasses of red wine.

What does this all mean?

According Wang, more research is needed to further substantiate the potential anti-cancer benefits of resveratrol.  He also stated there should be a clear focus on studying the effective dosage needed for cancer prevention as well as important factors such as interaction with other chemical compounds and timing.  In short – people shouldn’t be complacent with just taking large amounts of supplements.

The issue of overabundance

Nutrients (like vitamins, theanine and resveratrol) are still biological compounds, whether we like it or not.  With the proliferation of nutritional supplements in the market, it’s hard not to take extra doses of these supplements because of the health benefits.  Folic acid for one, is being taken in large amounts by people because of its numerous purported health benefits.

But did you know that too much of this nutrient can actually encourage the growth of cancer cells?

According to Joel Mason, a program director for the US ARS, cancer requires a very complex process in order to survive.  And one of the requirements for cell growth are nutrients like folic acid.

If you get more than four hundred micrograms of folic acid per day, you just might be encouraging the growth of cancer cells, instead of preventing it.

Too much folic acid can actually facilitate the DNA replication process necessary for the growth of cancer cells.  Watch what you eat – if you take a high-nutrient shake in the morning and eat folic-acid loaded snacks toward the end of the day, you just might be taking in too much of the nutrient.

Other benefits of resveratrol

1. Resveratrol helps promote a healthy heart by reducing oxidative stress and by improving blood circulation.  It also reduces the incidence of swelling or inflammation in the body’s tissues, as well as reduce unnecessary clotting in the blood vessels, which may lead to embolisms or even stroke.

2. In another study, it was shown that resveratrol prevented the initial processes required for cancer growth.

3. Studies show that resveratrol can help seniors by reducing the risk of neurological diseases and neural degeneration.

4. Coupled with calorie reduction, resveratrol can make a person resistant to many chronic and degenerative conditions such as heart diseases and even diabetes.

5. If used in conjunction with supplements like co-enzyme Q10 and omega 3 fatty acids, resveratrol can protect you from conditions like coronary heart disease.

6. Resveratrol has also been shown to reduce damage caused by stroke.

Kiwifruit, a world favorite, is now being seen as one of the leading “super foods” around because of myriad of health benefits, including its prebiotic potential and anti-cancer potential.

In a recently published Journal of Functional Foods, researchers from the NZ Institute of Plant and Food Research claim that pectin that has been derived from kiwifruit may help improve the levels of good bacteria in the digestive tract.

The humble pectin… was actually a health superstar!

The same pectins (the researchers found a total of six varieties of pectin in the species Actinidia deliciosa) the study says, may also help protect the good bacteria as they flourish in the digestive tract.  A growing body of studies suggest that the once humble pectin (usually used as a gelling agent for fruit jams and as material for encapsulating supplements and drugs) can provide the following benefits:

• Better digestion with pectin’s natural fiber content
• Prebiotics
• Increased heart health with its capacity to lower LDL (low density lipoproteins) or “bad cholesterol”

Compared to inulin fiber, the pectins from kiwifruit showed an enhanced effect on the good bacterias Lactobacillus rhamnosus and Bifidobacterium bifidum. The pectins also helped the body fend off bacterial invasions by lessening the adhesion of bad bacteria like Salmonella typhimurium.

Prebiotics?

The majority of health-inclined individuals around the world know of prebiotics. But how about prebiotics? What do they do?

Probiotics are compounds that encourage the growth and flourishing of good bacteria or essential bacteria in the digestive tract.  They directly contribute to the growth of the organisms in the intestinal flora.

Prebiotics on the other hand, protect the bacterial growth in the intestinal flora.  Since prebiotics are non-digestible substances they can also help carry away waste from the intestines.  Prebiotics are also important because they prolong the life of good bacteria and  they also keep the bacteria healthy.

Other benefits of prebiotics include:

1. May help ease the symptoms of diarrhea caused by taking antibiotics
2. Also helps people suffering from traveler’s diarrhea.
3. Helps reduce the pain and inflammation associated with gastroenteritis.
4. Helps normalize and regulate bowel function.
5. May help improve colitis
6. Can help reduce the incidence of irritable bowel problems.
7. Helps the body absorb calcium
8. Can help strengthen the immune system

Natural sources of prebiotics include:

• Whole grain products
• Leguminous foods
• Onions
• Fresh honey
• Fresh and cooked greens
• Garlic
• Yogurt, milk and other dairy products
• Different types of berries
• Bananas
• Apple cider vinegar (raw, not cooked)
• Jerusalem artichokes
• Other grains (gluten-free)

Amazing benefits of kiwifruit

Does kiwifruit offer other benefits other than prebiotics? Yes! Here are some of the main benefits of getting your healthy dose of kiwifruit everyday:

1. Kiwifruit is rich in vitamins and minerals, including ascorbic acid (vitamin C – one kiwifruit has more vitamin C than a regular orange), beta carotene and potassium. Potassium is brain food that increases one’s alertness and also improves one’s memory.

2. According to research performed in Italy, kiwifruit can also help improve the health of the respiratory tract. Seven portions of the fruit every week can yield respiratory benefits (respondents, children aged six to seven, showed less wheezing and shortness of breath compared to other respondents who received little or no kiwifruit throughout the testing period)

3. Kiwifruit  can also help ward off the effects of age-related macular degeneration.

4. Kiwifruit is a potent source of natural antioxidants, which can help reduce the incidence of certain types of cancer, heart disease and can also improve one’s vision.

5. Kiwifruit is a natural source of soluble fiber, which improves the digestive function and also helps transport human waste more efficiently.

6. Kiwifruit may be helpful in reducing harmful mutations or changes to one’s DNA. This is important in keeping your DNA pristine for the next generation (your children, who will be receiving your DNA – and all that comes with it, including risks to certain types of diseases, etc.)

7. Kiwifruit, because of its high soluble fiber content, can help individuals with insulin-dependent diabetes (or type-2 diabetes) and people with high cholesterol. Natural fiber has been known to control blood glucose levels and bad cholesterol levels.

8. Also due to its high fiber content, kiwifruit may also help prevent deadly colon cancer.

9. Kiwifruit is a natural source of the nutrient inositol. Recent studies show that inositol is very beneficial as a supportive treatment for depression.

10. It contains the compound arginine, which is capable of dilating or opening up constricted blood vessels.  As such, it is not only good for people with hypertension but is also very beneficial for males suffering from impotence or erectile dysfunction. Arginine has been long used for the treatment of impotence in males.

11. In China, a study made use of kiwifruit to see whether Chinese athletes can last longer during the rigorous physical exertion during training.  With the addition of five percent carbohydrates to kiwi juice, the athletes were able to last longer – their blood glucose levels remained stable after taking the kiwi juice.

12. Amazingly, this small fruit also has a high percentage of the natural brain chemical serotonin. This compound has a relaxing effect when utilized by the body.

Kiwifruit is a type of fruit that provides the best ratio of calories to fiber & essential nutrients.

Polyphenols, potent antioxidants found in shitake mushrooms, great tea and grape seed, may be the most effective natural immune booster the modern world has been looking for.

In a new study spearheaded by German scientists, it was found that a special juice mix composed of shitake mushrooms, green tea, grape seed and the extract from grape seeds may help reduce the occurrence of one of science’s most baffling problems: the common cold.

Because the common cold can be caused by literally hundreds of different pathogens, no single vaccination can be effective against it.  This is where the human immune system steps in: the stronger the immune system, the less likely for a person to suffer from the common cold.

Polyphenols vs. the common cold

The special juice mix had a high dose of natural polyphenols, one of nature’s most potent antioxidants.  According to researchers from Rudolf Wild GmbH, the proponent of the study, the respondents of their study are termed as being “immune impaired” because the test subjects have imbalanced diets, are overweight, etc.

Some respondents have also been exposed to physical stress. The researchers’ choice of respondents is important: because the subjects of the study are immune impaired, it is easier to measure their response to nutritional benefits.

Because nearly everyone, at least at one point in their lives, have been immune-impaired, the researchers stated that the results of their study can be accurately extrapolated for the rest of the population. This means that whatever benefits emerge from the study is potentially accessible to anyone who wishes to partake of the benefits of polyphenols.

The study reported a clear improvement in the test subjects who had been suffering from a general feeling of malaise, headaches, pain in the joints, nausea, hoarseness, coughing fits, etc.  The results were compared to a placebo group that showed little or no improvement throughout the testing period.

The testing ran for ten full days, with each respondent (in the test group) being given two doses of the polyphenol-rich juice mix.  All the respondents had a cold that started 24 hours or less before the 10-day study began.

Polyphenols as immune boosting compounds

The big question after the study was of course, “how did that happen?”  According to the researchers, the immune-boosting power of the polyphenol-rich juice mix may be due to the presence of the following compound, two of which have been associated with strengthening the body’s immune cells (T-cells):

• Catechines
• L-theanine
• 3-O glucoside
• Vitamin C (61.4 mg for every 500 milliliters of the juice mix)

The 3-O glucoside compound, found in grape seed, may also inhibit the formation of COX-1 enzyme and COX-2 enzyme. These two enzymes, known collectively as cyclooxygenase, have been linked with the increased incidence of tissue inflammation, ovarian cancer and colorectal cancer.

The critical role of antioxidants

Polyphenols have been long in the list of nature’s most efficient antioxidants.  Antioxidants are naturally occurring chemical compounds that protect the body’s cells from premature aging and destruction by removing free radicals.  Free radicals are by-products produced by the body’s cells – unfortunately, these by-products also have the ability to harm healthy cells.   Antioxidants reduce the damage by neutralizing these free radicals.

In addition to protecting the body’s cells from free radicals, antioxidants are also being studied for their potential role in reducing the incidence of breast cancer and also heart diseases.  In more recent years, it has also been linked to a reduced risk of developing Alzheimer’s disease, one of the most common medical conditions of the senior population in the United States.

Other benefits of antioxidants

For many decades, science has been testing and continually exploring the other possible benefits of antioxidants to the human body.  Here are just some of the established benefits of antioxidants:

1. May reduce the incidence of heart disease.

2. Helps boost the immune system.

3. May help slow down internal and external signs of aging.

4. Antioxidants such as vitamin C may also help improve respiratory function, skin health and bone health.

5. Selenium, a natural antioxidant found in fruits, vegetables, grains and meat, has been linked to increased killer cell activities and increased production of antibodies. Selenium has also been associated with the decreased incidence of prostate cancer, breast cancer and colorectal cancer.

6. Carrots, which contain a lot of beta carotene, may help reduce night vision problems and bodily infections. Eating carrots and other similar vegetables also enhance the body’s natural development.

7. Vitamin E protects the fats necessary for normal cell growth, reproduction and functions. Is also being hailed as the vitamin for slowing down age-related medical conditions.

8. Lutein, a natural antioxidant, may help promote healthier eyes and clearer vision.

9. Lycopene, a popular antioxidant found in tomato-based products, is very efficient in cleaning up the free radicals in the body and is also readily absorbed by the human body.

10. Antioxidants may help slow down the progress of chronic, degenerative diseases such as adult-onset diabetes.

Resveratrol, a naturally-occuring compound in wine, may help reduce cardiovascular disease and prolong life, new human study states.

Resveratrol is a naturally-occurring compound found in wines fermented from grapes.   This compound is a polyphenol and has been studied for many decades primarily because of the French Paradox: there is a low incidence of heart disease in France even though the French generally indulge in high-fat diets.

The French also smoke and drink a lot of wine throughout their lives.  One would expect that cardiovascular problems would be common, given the circumstances; however, something is keeping the French heart strong and healthy.  And according to Dr. Renaud, a French doctor from Bordeaux University, it was resveratrol that was to be given the credit.

Blood flow boost

In the United Kingdom, a human study (note – they used live human subjects for the test and not animals) researchers found out that 250 milligrams of resveratrol can help increase the blood flow to the brain, without producing any negative effects to a person’s cognitive capacity.  This fact alone, according to Dr. David Kennedy, signals a renewed interest in resveratrol and how it can affect vascular activity in the brain.

Another study from Harvard University showed that resveratrol was able to prolong the life of yeast cultures.  This study was done back in 2003, which actually helped increase resveratrol’s popularity with the media as a potential “eternal youth” pill.

Other studies showed that this polyphenolic compound was also capable of prolonging the life of other species such as mice and even nematodes.  What’s amazing about this compound is that it produces so many benefits and yet it’s just one type of molecule. It is as if Mother Nature designed resveratrol as a ‘heal-all’ for all living beings.

How much can you safely take?

It’s good to be always cautious and careful with anything that we ingest or consume.  Regular doses of resveratrol should not be given to children (that usually means kids below the age of 12) and pregnant or lactating women.  This is a general caution because there are still no conclusive studies done on the potential effects of this compound.

However, many researchers disagree with the warning about the dose.  According to James Betz, MD, tests show that at 1,000 mg of reseveratrol the polyphenolic compound failed to produce any significant negative effects to the test subjects.  Could it be possible that nature’s heal-all also doesn’t produce any side effects?

We leave this question open for the time being – it is up to medical researchers to prove or disprove.  But what we know now is this: resveratrol has a very big potential in prolonging the life of humans by protecting people’s hearts.  That is the main benefit and it is still the most interesting advantage to people who ingest resveratrol supplements.

Other benefits of resveratrol

This tough molecule does more than just protect the heart:

1. Resveratrol reduces inflammation in the body, which might benefit a lot of people in the long term because many medical conditions produce inflammation in the skin, joints, muscles and other body tissues.
2. Resveratrol reduces the incidence of blood clots, which may cause heart attacks, stroke, thrombosis, embolisms, etc.
3. Resvertarol is a natural anti-oxidant that can rid the body of harmful free radicals.
4. Resveratrol may also help in controlling cholesterol levels in the body (LDL cholesterol or bad cholesterol is its main target).
