Does Greek Yogurt Raise Blood Sugar?

Plain Greek yogurt is about as low-impact as a dairy food gets: the straining removes most of the lactose, leaving ~6 g of carbohydrate per container with a published GI near 11, alongside 17 g of protein.

How to Eat It

Plain and unsweetened, flavored with berries or a little cinnamon. The flavored versions — even “light” ones — add significant sugar and are a different product.

Estimated Glycemic Load

GL ≈ 0.7 per 1 container (170 g).

Calculation: GI (11) × available carbohydrate per serving (6.1 g = 3.6 g − 0 g fiber) ÷ 100. Calculated by DMSafeHaven; formula per standard published GL methodology.

Diabetes consideration: Excellent diabetes-friendly staple: high protein, very low GL - as long as it is plain and unsweetened.
What can change the impact?
  • Plain vs. flavored (flavored adds significant sugar)
  • Fat level

GI values can vary with variety, ripeness, preparation and testing conditions. The value above is a typical published figure, not a universal prediction for every individual or every serving.
