The consumption of certain dairy products might have a preventive effect on type 2 diabetes.
Several studies have analyzed the association of different levels of dairy consumption and diabetes, and although the studies left some things unconcluded, they showed that a high consumption of low-fat dairy clearly reduced the risk of developing type 2 diabetes.
One dairy product in particular stood out. Taken in 4-5 x 125 ml per week doses, yogurt, had the best effect in reducing the risk of T2D. Milk on the other hand, did not seem to show the same effect, which might suggest that the health benefit comes from the fermentation that products like yogurt go through.
Before treating any yogurt as a harmless meal, it is important to keep in mind that the product should be low-fat, and of course with a minimal amount sugar.
