Green Tea for Great Health - The Borneo Post - NH/16/19

Studies in green tea's value in maintaining good health have been conducted and reported in medical journals around the world.

Of particular interest are the studies, which indicate that green tea helps reduce the risk of cancer. Experts believe that its powerful antioxidants help to disarm free radicals (highly reactive oxygen compounds that damage healthy cells), which are believed to contribute to many degenerative diseases, including heart disease and cancer.

The American Journal of Epidemiology has reported that a study of 35,369 women and their incidence of cancer during an eight-year period linked regular green tea-drinking with a lower risk of cancers of the upper digestive tract, colon and rectum. In Britain, positive results have been attributed to using green tea to combat tumors of the colon, pancreas and breast. It is interesting to note that the amounts of green tea used were not megodoses, but only about four cups a day.

Because cancer researchers have concluded that some cancers are the consequence of the accumulation of cell damage often caused by free radicals, it has been particularly important to discover the antioxidants that can fight these damaging free radicals. Green tea is loaded with the powerful antioxidants called polyphenols, particularly EGCG, epigallocatechin gallate, the most powerful. EGCG has the ability to block the enzyme urokinase, which helps tumors grow by attacking neighboring cells. EGCG effectively destroys urokinase's ability to destroy good cells. Polyphenol's antioxidant ability helps cell DNA to reproduce itself accurately, rather than in a mutated form, and Chinese medicines from green polyphenols have long been used to treat nephri tip, hepatitis and even leukemia.

British researchers have discovered that four to five cups of green tea a day might help reduce both high cholesterol and high blood pressure. Green tea seems to work not only in reducing LDL cholesterol oxidation but also in lowering overall blood cholesterol levels. Scientists suspect green tea's antioxidants enter the bloodstream, attach themselves to LDLs, and duplicate the body's own antioxidants that the LDLs eliminate in the aorta. These positive antioxidants then protect LDLs from oxidation and protect the artery walls from damage.

New research is supporting green tea's use as a weight-loss aid. In a double-blind study in the American Journal of Clinical Nutrition, researchers tested the effects of green tea on 10 healthy men. They randomly gave the men one of three treatments at each meal - green tea extract (90 mg EGCG and 50 mg caffeine), caffeine (50 mg), or a placebo. After 24 hours, researchers found that only the green tea extract increased metabolism and energy use.
