So what is Greek Yogurt? Well, you'll find different opinions on this but it is yogurt with all essential pro-biotics still alive and thicker & creamier then regular yogurt.
Much of what you buy at the store is not really "yogurt" in my opinion it should be illegal to call it such. By the time they get through adding color additives, thickeners and sugars any pro-biotics that may have been in there are dead...thus it is no longer yogurt but a "dessert item" in my opinion with no health benefits! (more on pro-biotics after the lesson).
