Greek yogurt seems to be a new craze. It sure it thick as compared the the Regular.  Personally, I still like Stoneyfield Organic yogurt best.

On a low glycemic diet, you can combine a small serving of greek yogurt, with a fruit, and have a balanced low glycemic snack. That is pretty filling. :)

To me, it looks like if you use Greek yogurt, the protein content is higher per serving. This is great when you want to make balanced nutritional smoothies. But, companies are adding sugar, and sweetners to even this, so unless you get plain, I don't really see much benefit.

I have a book about making yogurt cheese. I also have a yogurt strainer. You can put a whole container of yogurt in it, and the liquid, some of the fat, and sugar will strain out, making a cream cheese consistancy. It is supposed to be less calories, and a little better for you than cream cheese. I haven't compared greek yogurt to yogurt cheese, but it looks to me to be very similar.

I use greek yogurt primarily in smoothies as the protein source when I want a balanced low glycemic meal or snack. I use plain, and add stevia or agave nectar as some sweetener, and also add something like blueberries or strawberries. I need to wipe the dust off my yogurt cheese book and see what else I can do with it.
