I came across this just prior to having surgery. It has 21 grams of Protein in one 8 oz. cup. No fat...22g carbs..should I stay away from it with all those carbs?

I'd skip it because of the sugar content -- 20g of sugar in most of the flavored ones. That said, the plain only has 10g carbs. So that wouldn't be as bad.

One of the better yogurts I have come across is the Dannon Light & Fit Greek yogurt. Offhand I know that the strawberry flavor has 80 calories, 8 carbs, and 12 g Protein. Comes in a wide variety of flavors too.

My flavored greek yogurt has 12-15 g Protein and under 15 carbs. I often take plain greek yogurt and add flavored Protein powder to it making it over 40g protein for only about 8 carbs.
