yogurt decreases type 2 diabetes risk
In plain terms: Does yogurt help prevent type 2 diabetes?
Part of: • Yogurt
Modestly, and yogurt stands out among dairy foods here - studies suggest roughly 7-14% lower risk at regular intake. The effect is small and comes mostly from observational data, with a few studies finding nothing, so think of yogurt as a helpful part of a good diet, not a diabetes shield.

What the evidence shows
Yogurt is the one dairy food that fairly consistently shows a modest inverse link with type 2 diabetes — several dose-response meta-analyses estimate roughly 7–14% lower risk at moderate intake (around 80 g/day), and yogurt often stands out even when milk and cheese do not.

Disagree, or know a study we missed?
We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
Opens a short form. You'll sign in with Google so submissions are tied to a real account — we don't display your identity, and we only accept a link we can verify (PubMed, DOI, ClinicalTrials.gov).
