Well lets start with what Greek yogurt actually is. It’s made for the most part the same as regular yogurt, except Greek yogurt has the liquid strained out of it, so it has a thicker texture and more protein. Other than that, Greek yogurt is the same. Depending on the brand and the you’re of milk, yogurts can have alot of bacteria, or almost none at all. The main benefit is you can replace other high in fat foods with it, so it is good for diets. Also it is traditionally made from goat milk, but most of what you find in stores is made from moo juice. If healthy is what you’re going for, buy the plain unflavored stuff and add your own flavor, as you have more control as to what goes in.
