Dr. Jo Ann Carson, professor of clinical nutrition at the University of Texas Southwestern Medical Center in Dallas, says studies from various countries suggest a lifetime consumption of at least two to four cups of tea per day -- black tea, in particular -- reduces the incidence of type 2 diabetes.
However, Carson says while scientific evidence on tea's health benefits is limited, all teas -- green, white, black and oolong -- can be part of a healthy diet.
Carson says people have two choices -- learn to enjoy iced tea with little or no sugar, or drink sugared iced tea in moderation, generally once a day or less.
