Dairy product consumption is correlated to lower cardiovascular risk: results from the DESIR study

Nutrition plays an important role in the management of type 2 diabetes (T2DM). The French epidemiological study DESIR was a prospective, cross-section study that investigated the role of dairy product consumption in the development of impaired glucose metabolism and metabolic syndrome (MetS). Only subjects (n = 3,435) who were nondiabetic at study entry, not on diet restrictions and completed a food frequency questionnaire at baseline and at 3 years were included. The relationships of dairy products and calcium intake and 9-year incident MetS, T2DM and impaired fasting glucose (IFG) were analyzed after adjusting for confounding demographic and lifestyle factors such as age, gender, alcohol and fat intake, smoking and physical activity. Distinction was made between cheese vs. milk and other dairy products due to differences in nutritional content. Dairy product consumption and amount of calcium ingested were inversely correlated with MetS and IFG/T2DM incidence, cheese only with MetS. Cheese consumption and calcium intake were associated with lower waist conference increase and improvement in triglyceride levels. All three measurements were positively correlated with lower blood pressure and less weight gain. The results show that dairy products, despite their high saturated fat content, have cardiovascular benefits, with implications on nutritional management strategies (Fumeron, F. et al. Diabetes Care 2011, 34(4): 813).
