Fruit Consumption and Risk of Type 2 Diabetes: Results from Three Prospective Longitudinal Cohort Studies.

Study Question

Are individual fruits, which vary in composition, differentially associated with risk of type 2 diabetes, and, if so, do the associations depend on the glycaemic index or glycaemic load of the individual fruits?

Summary Answer

Greater consumption of specific whole fruits, particularly blueberries, grapes, and apples, was significantly associated with a lower risk of type 2 diabetes, whereas greater fruit juice consumption was associated with a higher risk. These differences in association were not explained by the glycaemic index (quality of carbohydrate) or glycaemic load (quality and quantity of carbohydrate and their interaction) values of the fruits.

What is Known and What This Paper Adds

In previous studies total fruit consumption was not consistently associated with a lower risk of type 2 diabetes. The current study shows that the inconsistency may be explained by the differences in association between individual fruits, but not by the glycaemic index or glycaemic load values of the specific fruits.
