Green Tea Protects Against Cancer
More studies show that drinking green tea regularly may have a protective effect against many types of cancer, including breast, lung, prostate, and colon cancer. British researchers have also found that the popular beverage that has been enjoyed for at least 3,000 years could also reduce the risk for Alzheimer’s disease and burn fat in people who are trying to improve their weight.
Although both green tea and black tea come from the same Camellia sinensis plant, green tea is healthier because it is less processed and it contains three times more antioxidants than does black tea according to the American Institute for Cancer Research (AICR).
There has been a recent surge of studies demonstrating green tea contains anti-cancer catechins called epigallocatechin gallate (ECGC). The National Cancer Institute (NCI) reports that ECGC prevents tumor growth by reducing DNA damage, blood vessel growth around tumors, and tumor invasion. They also activate detoxification enzymes and protect against damage from ultraviolet B.
Brewed green tea is believed to contain more catechins than ready-to-drink green tea products found in grocery stores. Although the optimal dose is unknown, people in Asian countries typically consume about three cups per day.
Green tea dietary supplements are also available, but experts from the US Department of Agriculture say that many of these products are labeled incorrectly. They also report that many beneficial compounds in green tea, including catechins are destroyed during manufacturing and storage, while some products do not contain green tea at all. Study authors therefore believe that green tea supplements may not be a good alternative for real tea leaves when their chemical compositions are considered.
