Is dairy bad for PCOS?
TL;DR
Conventional A1 dairy can raise IGF-1 and insulin spikes in some people with PCOS. Fermented, A2, or elimination trials are the most practical way to personalize dairy—not a one-size rule for everyone.

Should everyone with PCOS quit dairy?
No. PCOS is heterogeneous. A structured 3–4 week elimination with symptom and cycle logging—then a careful reintroduction—is more informative than generic advice.
Is Greek yogurt okay?
Plain, full-fat, unsweetened fermented dairy often behaves differently than sweetened low-fat products. Track your own glucose response and skin/digestive symptoms.
