Dairy Consumption and Risk of Type 2 Diabetes Mellitus in Men

the relative risk for type 2 diabetes in men in the top quintile of dairy intake was 0.77 (95% confidence interval [CI], 0.62-0.95; P for trend, .003) compared with those in the lowest quintile. Each serving-per-day increase in total dairy intake was associated with a 9% lower risk for type 2 diabetes (multivariate relative risk, 0.91; 95% CI, 0.85-0.97). The corresponding relative risk was 0.88 (95% CI, 0.81-0.94) for low-fat dairy intake and 0.99 (95% CI, 0.91-1.07) for high-fat dairy intake. The association did not vary significantly according to body mass index (25 vs 25 kg/m 2 ; P for interaction, .57). Conclusion: Dietary patterns characterized by higher dairy intake, especially low-fat dairy intake, may lower the risk of type 2 diabetes in men. Arch Intern Med. 2005;165:997-1003
