Phil Lempert, a food industry analyst, trend watcher and creator of supermarketguru.com, said studies also show tea drinkers are less likely to suffer from cardiovascular disease than non-drinkers, and a recent study discovered black tea lowers systolic and diastolic blood pressure.
Black tea is also packed with flavonoids, antioxidants that help combat free radicals that cause cellular damage and aging.
Flavonoids also help prevent the oxidation of "bad" cholesterol, protect blood vessels from inflammation and inhibit blood clotting.
Black tea is also a natural source of fluoride, which can help strengthen tooth enamel, and helps cut down plaque on teeth.
Tea, which has no calories, contains about half the amount or less of caffeine as coffee, Lempert said.
"Look for fair trade certified, which ensures that farmers are getting paid fairly, and that your tea is grown sustainably," Lempert said in a statement. "Choose loose leaf tea for a rich tea experience, but if loose leaf is not available at your local grocer, read tea labels for ingredients -- stay away from teas with artificial flavors and added sugars."
