Not all carbohydrates are created equal, and when it comes to diabetes prevention, whole grains may be particularly beneﬁcial. To see how diabetes risk relates to whole grain intake, researchers analyzed the grain foods eaten by 55,465 older adults and monitored them for diabetes. Over the 15-year study period, each 16-gram serving of whole grains was linked with an 11% and 7% lower risk of type 2 diabetes in men and women, respectively. The researchers also looked at the beneﬁt of diﬀerent whole grain foods, noting that rye bread, whole-grain bread, and oatmeal/muesli were all signiﬁcantly linked with a lower risk of type 2 diabetes in both men and women.
