Every 3 servings per week of blueberries is associated with a 26% reduction in risk for T2DM, according to a recent prospective longitudinal cohort study.[2,3] The investigators also observed a 12% reduction with the consumption of grapes, even though these fruits have a high glycemic index. Other specific whole fruits, such as apples, bananas, and grapefruit, were significantly correlated with a lower risk of developing diabetes, whereas peaches, plums, apricots, and oranges had a neutral effect. Drinking a greater amount of fruit juice was associated with an increased risk, and the substitution of whole fruits for juice was linked to a lower risk, except for cantaloupe and strawberries.

In summary: The consumption of whole fruits (especially blueberries and grapes) rather than their juice is associated with a reduced risk of developing type 2 diabetes.
