While all yogurt provides numerous health benefits (including probiotics), the nutritional value of Greek yogurt and regular yogurt differ.
Protein -- Greek yogurt has almost double the protein of regular yogurt. Eight ounces of Greek yogurt has about 20 grams of protein, whereas regular yogurt provides around 11-13 grams. Greek yogurt's high protein content makes it a favorite among people trying to manage their weight as it helps ward off hunger.
Carbohydrates -- Greek yogurt has fewer carbohydrates than regular yogurt. This could be beneficial to diabetics, who have to watch their carbohydrate intake.
Calcium -- Regular yogurt has about three times the calcium of Greek yogurt. Both are still considered good sources of calcium, but women who don't get enough calcium from other foods may want to stick to regular yogurt for its bone-building benefits.
Sodium -- Greek yogurt has half the sodium of regular yogurt.
Calories -- Plain, nonfat Greek and regular yogurt have a similar amount of calories per serving.
Texture -- Greek yogurt is much thicker and creamier than regular yogurt because it's strained more. Greek yogurt can also be used in cooking as it does not curdle when heated like regular yogurt.
Cost -- You'll likely spend twice the money on Greek yogurt. This is largely due to escalating customer demand, as Greek yogurt's taste, texture, and great nutritional profile keep consumers coming back in droves. Greek yogurt also costs more because the extra straining requires much more milk, so it's a more concentrated source of protein.
