Summary

This large prospective analysis pooled data from three US cohort studies — the Nurses' Health Study, Nurses' Health Study II, and Health Professionals Follow-up Study — to investigate how consumption of whole fruits and specific fruit types relates to incident type 2 diabetes. The study likely found that greater consumption of certain whole fruits, particularly blueberries, grapes, and apples, was associated with a reduced risk of type 2 diabetes, whilst greater consumption of fruit juice was associated with increased risk. The findings suggest that the food form and specific fruit type matter, not merely fruit consumption in aggregate.

UK applicability

Although conducted in US populations, the dietary and metabolic mechanisms are broadly applicable to UK public health contexts, and the findings are relevant to NHS dietary guidance on fruit consumption and diabetes prevention strategies in the UK.

Key measures

Hazard ratios for type 2 diabetes incidence; fruit consumption frequency (servings per week); individual fruit types including blueberries, grapes, raisins, prunes, bananas, cantaloupe, apples, pears, oranges, grapefruit, strawberries

Outcomes reported

The study examined associations between consumption of individual fruits and risk of developing type 2 diabetes. It assessed whether different fruit types conferred differential risk or protective effects.
