Dairy products and the risk of type 2 diabetes: a systematic review of cohort studies

diabetes - yogurt

This meta-analysis suggests that there is a significant inverse association between intakes of dairy products, low-fat dairy products, and cheese and risk of type 2 diabetes.

Seventeen cohort studies were included in the meta-analysis based on the PubMed database. The authors observed a dose-response effect. The RRs were calculated as follows:

  • 0.93 per 400 g total dairy products/d
  • 0.98 per 200 g high-fat dairy products/d
  • 0.91 per 200 g low-fat dairy products/d
  • 0.87 (0.72, 1.04; I2 = 94%) per 200 g milk/d
  • 0.92 (0.86, 0.99; I2 = 0%) per 50 g cheese/d

The impact of yogurt is even stronger with an RR of 0.78 per 200 g yogurt/d. Nonlinear inverse associations were observed for all categories of dairy products, but there was a flattening of the curve at higher intakes.
