Could tea be a health beverage? Eleven new studies in the American Journal of Clinical Nutrition highlight the many ways that tea may improve health: Tea drinking appears to lower the risk for heart disease and stroke, may strengthen bones, and appears to improve mood, concentration, and performance. Natural compounds called polyphenols in tea might protect against several cancers, including those of the prostate, GI tract, lungs, breast, and skin, and may also increase metabolism and promote weight loss. Those possible benefits apply to tea, not tea extracts condensed into pills. If you’re a tea drinker, enjoy your favorite brew with the added satisfaction that it may be good for your health. If you aren’t, there’s no reason to start.
