While tea is a low-calorie beverage (if drunk without cream and sugar), there is no definitive evidence that it has greater health benefits, according to Howard Sesso, associate professor in the Department of Epidemiology at Harvard T.H. Chan School of Public Health.
Some studies have shown promising evidence of benefits, but they were mostly conducted in Asia and their findings might not be generalizable in the U.S., where people drink far less tea, Sesso said in a January 22, 2019 article in the Chicago Sun Times. And given that different types of tea contain differing amounts of potentially health-promoting bioactive compounds, a specific recommendation around drinking tea would be tricky, he said.
The bottom line? No need to “go out and start drinking six to eight cups of tea a day,” he said.
