A new study conducted by researchers at the University of Scranton suggests that tea might prevent diabetes and its ensuing complications, including cataracts. Researchers led by Joe Vinson fed green and black tea to diabetic rats for three months and then monitored the chemical composition of the rats' blood and eye lenses.

At levels that would be equivalent to less than five cups of tea per day for a human, both teas significantly inhibited cataract formation in comparison to a control group which did not get tea. The researchers found that both teas decreased glucose levels, which in turn affects other biochemical pathways that accelerate diabetic complications such as cataracts. "Most people, scientists included, believe that green tea has more health benefits than black tea," Vinson added.
