Food Guys Jon Jackson and Greg Patent discuss a study comparing whether fruit juice is as effective at preventing Type 2 diabetes as whole fruit. It's not. In fact, fruit juice consumption is associated with a heightened risk.
According to the Harvard School of Public Health:
"Eating more whole fruits, particularly blueberries, grapes, and apples, was significantly associated with a lower risk of type 2 diabetes, according to a new study led by HSPH researchers. Greater consumption of fruit juices was associated with a higher risk of type 2 diabetes. The study is the first to look at the effects of individual fruits on diabetes risk."
