Is dairy fat linked to a lower risk of type 2 diabetes, as some studies claim?

Spanish researchers tracked roughly 3,350 people aged 55 to 80 who participated in the PREDIMED study for four years. All were at high risk of cardiovascular disease, and most were overweight or obese.

Participates who consumed the most saturated fat were twice as likely to be diagnosed with type 2 diabetes as those who consumed the least.

In particular, butter and cheese were linked to a higher risk, while full-fat yogurt was linked to a lower risk. (The study didn’t look at lower-fat yogurt.)

What to do: It’s too early to know if cheese and butter raise–or if yogurt lowers–the risk of diabetes because this type of study can’t prove cause and effect. For now, your best bet is to eat less red meat and to stick to lower-fat diary foods to lower your risk of heart disease.
