Mixed
Consumption of specific whole fruits, particularly blueberries, grapes, and apples, is associated with a significantly lower risk of type 2 diabetes, whereas fruit juice consumption is associated with a higher risk.
Focus on whole fruits, specifically blueberries, grapes, and apples, to help lower your risk of type 2 diabetes. Limit fruit juice, as it is associated with higher risk. The type of fruit matters more than the total amount or glycemic index.
GoodSupportsHIGH confidence
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.
Why this rating
Large prospective cohort studies (N>180,000) with long follow-up and mutual adjustment, though observational design limits causal certainty.
