Whole Grains and T2 Diabetes in Older Women

Using data from the prospective Women’s Health Initiative (WHI) Observation Study investigators in the US analyzed the relationship between whole grain consumption and the incidence of Type 2 Diabetes (T2DM). Over a median follow-up period of 7.9 years a strong relationship was found between increased whole-grain consumption and reduced risk of T2DM. The findings from this study also provide support for the hypothesis that the association between whole grain consumption and the incidence of T2DM is modified by weight loss and smoking.
