Type 2 Diabetes risk lowered by consuming whole fruits.

fruits and vegetablesA new study released by Harvard School of (HSPH) was associated with a lower risk of , whereas consumption of fruit juices was associated with a higher risk.

The study is the first to look at the effects of individual fruits on and found that eating more whole fruits, particularly , grapes, and apples lowered the risk of .

“While fruits are recommended as a measure for diabetes prevention, previous studies have found mixed results for total . Our findings provide novel evidence suggesting that certain fruits may be especially beneficial for lowering ,” said senior author Qi Sun, assistant professor in the Department of Nutrition at HSPH and assistant professor at the Channing Division of Network Medicine, .

The researchers looked at overall , as well as consumption of individual fruits: grapes or raisins; peaches, plums, or apricots; ; bananas; ; apples or pears; oranges; grapefruit; strawberries; and . They also looked at consumption of apple, orange, grapefruit, and “other” fruit juices.

It was determined that people who consumed at least two servings each week of certain whole fruits — particularly , grapes, and apples — reduced their risk for by as much as 23% in comparison to those who ate less than one serving per month. Conversely, those who consumed one or more servings of fruit juice each day increased their risk of developing by as much as 21%. The researchers found that swapping three servings of juice per week for whole fruits would result in a 7% reduction in .

The researchers attributed the beneficial effects of certain individual fruits to a particular component. Previous studies have linked anthocyanins found in berries and grapes to lowered heart attack risk, for example. More research is necessary to determine which components in the more beneficial fruits influence .

“Our data further endorse current recommendations on increasing whole fruits, but not fruit juice, as a measure for diabetes prevention,” said lead author Isao Muraki, research fellow in the Department of Nutrition at HSPH. “And our novel findings may help refine this recommendation to facilitate diabetes prevention.”
