What is the effect of drinking tea on your health? The efficacy and function of Tea: a New Theory that Tea polyphenols in Tea are beneficial to organisms

Eating green tea polyphenols has great benefits because a diet rich in antioxidants is associated with delaying aging and is one of the most effective ways to treat high blood pressure. Three cups of coffee a day can significantly reduce systolic blood pressure, fasting blood sugar and weight loss in patients with type 2 diabetes, the researchers said. the mechanism by which tea neutralizes or prevents oxidative stress is unclear, but it is associated with a group of catechins. Epigallocatechin gallate (Epigallocatechin gallate, EGCG) is the most abundant. The researchers believe that this benefit is defensive, protecting individual cells from damage. Green tea catechins not only neutralize harmful free radicals, but also improve the ability of laboratory biological cells to live longer and healthier, according to a new study published in the journal Aging. "this means that green tea polyphenols or catechins are actually not antioxidants, but promotive oxidants that improve the body's self-defense capabilities, similar to vaccines," lead researcher Michael Risto (Michael Ristow), a professor of energy metabolism in the Department of Health Science and Technology at the Federal Institute of Technology in Zurich, told Future magazine in an article entitled the Future. The discovery of green tea subverts people's perception of its health benefits.

The paper, published by Peter Luger (Peter Ruegg) of the Federal Institute of Technology (ETH Zurich) in Zurich, explains that, unlike vaccines that stimulate the immune system, green tea activates genes that produce enzymes, such as superoxide dismutase (SOD) and catalase (CTL), which inactivate free radicals in nematodes, which are the experimental organisms of choice. Initially, the presence of catechins increases oxidative stress in a short period of time, thereby increasing the defense capabilities of cells and the body, Ruegg wrote. Risto says the results of the study apply to humans. "the basic biochemical process of neutralizing oxygen free radicals in organisms is conservative in the history of evolution, from single-celled yeast to humans," he said. " Ristow, who is also a green tea enthusiast, says catechins are more abundant in green tea than in black tea because polyphenols are largely destroyed during fermentation. The British Tea Advisory Council (UK Tea Advisory Panel) cited a meta-analysis of 24 health studies involving 1697 patients to support drinking moderate amounts of green tea. "EGCG, the main phenolic compound in green tea, increases nitric oxide levels, thereby lowering blood pressure," the team wrote on Twitter. " Globally, about 30% of adults have high blood pressure, which is a major risk factor for cardiovascular disease and early death. In the United States, high blood pressure (systolic blood pressure greater than 130mm Hg) affects 47 per cent of adults, causing 1/6 deaths.
