Random Tea Tidbit

Take frequent tea breaks this winter, and you may just get through it without a sniffle. Immunologists at Harvard University discovered that people who drank five cups of black tea a day for 2 weeks transformed their immune system T cells into "Hulk cells" that pumped out 10 times more cold and flu virus-fighting interferon than did the immune systems of those who didn't drink black tea. Green tea should work just as well. "Not just the common cold and flu, but food poisoning, infected cuts, athlete's foot-even diseases such as tuberculosis and malaria-are caused by germs that your body fights with interferon. We think the interferon boosts from tea may help prevent or lessen the severity of all these conditions," says Jack Bukowski, MD, PhD. While five cups a day may seem like a lot, he thinks fewer cups may still offer some valuable protection. "And the interferon link may explain tea's other health benefits, including its reported cancer-fighting power, since we already know that interferon slows the growth of tumor cells," says Bukowski.

A new study from Japan was published this week showing that green tea may help with stress. The study found that drinking green tea may reduce psychological stress by as much as 20 percent. In this study of 42,093 Japanese individuals, 6.6% suffered from psychological stress. In those individuals suffering from stress, green tea consumption improved psychological well-being.

Researchers at Harvard University found that drinking five cups of black tea a day quadrupled the body's immune defense system after two weeks, probably because of theanine. Tea also contains catechins, including ECGC, which act like a cleanup crew against free radicals. Grotto suggests drinking one to three cups of black, green or white tea every day.
