Tea provides a degree of protection against the development and progression of cardiovascular diseases, according to an article in the February 2006 issue of "Molecular Nutrition & Food Research." There is evidence that the flavonoids found in tea reduce lipids, inflammation and the formation of blood clots in arteries, but there the results of clinical studies in humans have not been consistent. In spite of this, drinking tea is a considered a good way of combating cardiovascular disease.
Enhanced Insulin Activity
requires insulin so that it can convert glucose, or sugar, to energy. Drinking teas that are made from leaves of Camellia sinensis -- such as black, green or oolong tea -- was found to increase insulin activity, according to an article in the November 20, 2002, issue of "Journal of Agricultural and Food Chemistry." The article adds that adding lemon to the tea does not reduce this benefit.
