New data bolsters key health benefits of tea
Recent studies published in a supplement of the American Journal of Clinical Nutrition confirm some of the key health benefits associated with tea consumption. 12 new articles by world-renowned scientists explore how tea may reduce risk of certain cancers, promote weight loss, improve bone health and activate areas of the brain that bolster attention, problem solving and mood. For example, in a double-blind, placebo-controlled study, green tea polyphenols were shown to reduce the progression of prostate cancer in men. Another study looked at cardioprotective features of black tea and found that it reduced blood pressure, and among hypertensive subjects, helped counteract the negative effects of a high-fat meal on blood pressure and arterial blood flow. Finally, psychological effects of tea were also under the scope: 2-3 cups were shown to improve mental alertness and mood. The studies were hailed as a significant advancement of research into tea and human health.
