Type 2 Diabetes risk lowered by consuming whole fruits.

fruits and vegetablesA new study released by of () was associated with a lower risk of type 2 diabetes, whereas consumption of was associated with a higher risk.

The study is the first to look at the effects of individual fruits on diabetes risk and found that eating more whole fruits, particularly , grapes, and apples lowered the risk of type 2 diabetes.

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

The researchers looked at overall fruit consumption, 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” . The study pool consisted of data gathered between 1984 and 2008 from 187,382 participants in three long-running studies (Nurses’ Health Study, Nurses’ Health Study II, and Health Professionals Follow-up Study). Participants who reported a diagnosis of diabetes, cardiovascular disease, or cancer at enrollment were excluded. Results showed that 12,198 participants (6.5%) developed diabetes during the study period.

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 type 2 diabetes 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 each day increased their risk of developing type 2 diabetes 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 diabetes risk.

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 diabetes risk.

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