If you've ever stood in the dairy aisle in your grocery store, holding one cup of regular yogurt, and one cup of the Greek stuff, and wondered whether the extra money is worth it, you're not alone. Food bloggers, cooking shows, and even healthcare professionals seem to encourage eating Greek yogurt over its counterpart. But why? Does it matter which you choose? Can you use regular yogurt where Greek is suggested?

As it turns out, not all yogurt is created equal. Along with a bigger price tag, Greek yogurt contains about twice the protein of the other kind, which makes it great for smoothies and sauces, or as a whole meal by itself. It doesn't contain as much calcium as regular yogurt, but does boast a lower carb count, giving it favor with dieters and health nuts worldwide. It's also thicker than regular yogurt, so it doesn't need artificial thickeners.

This is because Greek yogurt is "triple-strained," meaning it's strained out three times, as opposed to the two times regular yogurt is strained. This separates out the more watery parts of yogurt, such as water and whey. It's why Greek yogurt tends to have less calcium (which is found in whey), and is a bit thicker. In the end, any yogurt you use can work, but if you're looking for more protein, fewer carbs, and a thick product, always go for Greek!
