TORONTO—Sometimes it’s OK to go a little crazy, or in this case, “nutty”. Researchers said, even though more studies may be needed to establish the ability of nuts to improve glycemic control in the long run, early data supports and warrants nuts in diet for individuals with diabetes and the metabolic syndrome in view of their potential to reduce coronary heart disease (CHD) risk (Br J Nutr. May 5, 2010).
Results from cohort studies have associated nut consumption with a reduced risk of developing diabetes and cardiovascular disease (CVD). However, few randomized controlled trials have assessed the effect of nuts on diabetes control, and those that have been undertaken have shown improvements in blood lipids but not in the glycemic control. Diabetes agencies are increasingly recognizing the importance of controlling postprandial glycemic fluctuations. Acute feeding studies indicate nuts have minimal effects on rising post-meal blood glucose levels when eaten alone, and diminish the post-meal glycemic response when consumed with high-glycemic index carbohydrate foods in both normoglycemic and type 2 diabetic individuals. Nuts have a healthy nutritional profile. They are high in monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA), and are a good source of vegetable protein and are rich in fiber, vitamins and minerals. Incorporation of nuts in the diet may therefore improve the overall nutritional quality of the diet.
