An analysis of the diet and health records of thousands of people revealed that those who ate two or more daily servings of fruits like blueberries, grapes, raisins, prunes, apples, and pears reduced their likelihood of developing type 2 diabetes by 23%. However, the study also showed that drinking fruit juice daily increased the risk of diabetes by 21%. The findings suggest that eating more whole fruits can help prevent the onset of diabetes.
