BBC News: Tea 'healthier' drink than water.
Drinking three or more cups of tea a day is as good for you as drinking plenty of water and may even have extra health benefits, say researchers. The work in the European Journal of Clinical Nutrition dispels the common belief that tea dehydrates. Tea not only rehydrates as well as water does, but it can also protect against heart disease and some cancers, UK nutritionists found. Experts believe flavonoids are the key ingredient in tea that promote health. These polyphenol antioxidants are found in many foods and plants, including tea leaves, and have been shown to help prevent cell damage.
Tea has less caffeine than coffee too. Found Pom Tea, a mix of tea and pomegranate juice, in Whole Foods, very nice!
