Purported Health Benefits of Tea

Natural substances, called polyphenols, are found in both caffeinated and herbal teas. These substances are antioxidants, compounds that may help reduce the risk of certain chronic diseases.

During processing, some of the polyphenols in tea are destroyed. Thus, tea powders, decaffeinated teas and bottled tea drinks may not offer the same health benefits. Additionally, research suggests that green teas offer a greater antioxidant punch compared to most other varieties.
