Supplementation can be a powerful force against disease. And, recent evidence gives additional evidence for the benefit that Green Tea supplementation can be against the flu.

Green tea supplements prevent flu better than vaccination

“(NaturalNews) Flu season is now in full swing and seasonal vaccinations are being pushed from every corner. Nonetheless, a recent clinical trial showed that green tea-based supplements reduced the risk of flu by 75%. This is far better than the 60% risk reduction recently reported in the Lancet for vaccinations. Given that green tea provides a host of other health benefits and none of the risks of injections, it would appear to be a far superior alternative to vaccination.

Green Tea: Natural Antiviral and Immune Enhancer

For many years it has been known that green tea polyphenols actively suppress many bacterial, fungal and viral species. On the virus front, green tea suppresses the adenovirus, Epstein-Barr, herpes simplex, HIV-1 and influenza viruses. EGCG, one of the main polyphenols in green tea, is mainly responsible for this suppression. Specifically, ECGC binds to the hemagglutinin of the influenza virus, which blocks it from attaching to (and infecting) target receptor cells. EGCG also alters the virus cell membrane, which further inhibits its ability to infect other cells. Another important component of green tea is the amino acid L-theanine, which has been shown to activate human gamma-delta-T lymphocytes to proliferate and make interferon-gamma, a potent antimicrobial cytokine. These lymphocytes are considered to be the body’s first line of defence against infection. Green tea therefore offers a two-pronged protection from the flu which vaccination simply cannot match. But for final proof, we need clinical trials.

Green Tea Lowers Flu Risk: Early Clinical Evidence

One early trial using green tea against the flu involved gargling three times daily with a weak solution of green tea (50 mg of catechins per cup, of which 60% was EGCG). The theory was that since the throat was a major infection site of influenza, gargling could stop the flu virus there. The theory was right: 1.3% of garglers contracted the flu vs. 10% of the control group. In another more sophisticated trial on 97 healthy adults, a proprietary blend of theanine and green tea polyphenols (apparently worth about 10 cups of green tea per day, but exact amounts were not disclosed) was used for three months during flu season. This trial was randomized, double-blind and placebo controlled. The supplement takers experienced 32% less illnesses and 35% fewer ‘symptom days.’ However, participants were included in the statistical analysis even if their compliance (actually taking the green tea pills) was only 70%.

Latest Clinical Trial Provides Stunning Results: 75% Less Illness

More recently, a better controlled trial was performed on 198 health care workers. This was randomized, double-blind and placebo controlled: the gold standard in clinical trials. The treatment group was each given a daily dose of 378 mg green tea catechins (containing 270 mg EGCG) and 210 mg of theanine from November 2009 to April 2010. The compliance rate in this trial was better: 93% took their pills according to plan. Those taking the green tea experienced 75% less clinically defined flu infection and this was statistically significant (P=0.022). But not all observed sicknesses were bona fide flu. When laboratory tests were used to confirm real influenza infection, it showed that green tea provided a stunning 83% reduction in flu risk, however this was not statistically significant (P=0.112) due to the small number of actual flu cases.

This latest trial shows that green tea supplements easily outperform flu vaccination for preventing illness. This may be a shocker to most people’s vaccine-indoctrinated mind-set, but for those who already study, understand and practice the principles of natural health, it’s really no surprise at all.”

There has been a lot of good news for coffee drinkers of late… and this one is no exception! Coffee can be protective against cancer? Another reason to raise your mug and salute your morning brew!

Coffee Emerges As Protective Against Cancer And Other Diseases

“Starbucks fans around the world can rejoice that their tipple gets the thumbs up yet again. Already shown to protect against a number of diseases, a recent study in the Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research, shows coffee drinkers who consumer more than four cups a day with a 25% lower risk of Endometrial Cancer. It is thought that the antioxidant properties in coffee may be a part of the mechanism.

Edward Giovannucci, M.D., Sc.D., professor of nutrition and epidemiology at the Harvard School of Public Health, and a senior researcher on the study, said coffee is starting to be proven as a protective agent in cancers that are linked to obesity, estrogen and insulin.

‘Coffee has already been shown to be protective against diabetes due to its effect on insulin … So we hypothesized that we’d see a reduction in some cancers as well.’

Giovannucci, and his colleagues, including Youjin Je, a doctoral candidate in his lab, looked at endometrial cancer cases in nearly 70,000 women who enrolled in the Nurse’s Health Study. Over 26 years they documented 672 cases of endometrial cancer. More than four cups of coffee was linked with a 25% decrease in risk, while two to three cups had a 7% lower risk.

The results seemed to hold true for decaf as well, with a 22% reduction for more than two cups per day.

Giovannucci said he’d like to see further research on the effects of coffee on cancer, because in this and similar studies, coffee intake is self-selected and not randomized.”
