"Decaffeinated tea is better," says Fleming, noting that the caffeinated variety can be dehydrating, and sugary drinks can lead to weight gain.
There is some evidence that tea may help in improving memory, and preventing cavities, cancer, and heart disease. Fleming says, though, that the overall research is still inconclusive.
"There may well be some beneficial effects of tea, particularly the potential antioxidant effect, but we don't have great data on that right now that is that specific."
However, there's no doubt that a cool iced tea can be a refreshing treat during hot days. Try flavoring your tea with juices, fruits, cinnamon sticks, ginger, and other condiments.
