Whole Grains Lower Insulin and Triglycerides in People with Metabolic Syndrome
Studies suggest a relationship between whole grain intake and insulin action. In a study in Italy, 53 adults (40-65 years old) with metabolic syndrome followed one of two diﬀerent 12-week diets. One group consumed their standard diet, but replacing all grains with whole grains, and one group consumed their standard diet, but choosing only reﬁned cereals. Researchers found that the whole grain group had signiﬁcantly lower levels of post-meal insulin (29%) and triglyceride levels (43%) than before the 12-week test period, thus reducing the risk for heart disease and type 2 diabetes. Based on these ﬁndings, the researchers suggest that “the whole-grain diet was able to improve insulin action” after meals, thus providing clues about how whole grain diets reduce the risk of chronic disease.
