Not to be outdone by coffee, a report in the European Journal of Clinical Nutrition says that 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.
(The report dispels the common belief that tea dehydrates. It not only rehydrates as well as water does, but it can also protect against heart disease and some cancers, because of the presence of flavonoids. The study was funded by The Tea Council.)
