A few cups of black tea a day might help to avoid an early death, a study published in Annals of Internal Medicine suggests. Among nearly half a million adults ranging from 40 to 69 years old, those that consumed two or more cups of tea a day saw a modest, but lower risk for all causes of mortality over a median follow-up of more than 11 years. Participants of the large cohort study, called UK Biobank, self-reported tea intake from 2006 to 2010, while researchers noted mortality from all causes, including cardiovascular disease, ischemic heart disease, stroke and respiratory disease. The researchers concluded that drinking more than two cups of tea per day can be part of a healthy diet.
