Skyr vs yogurt: nutrition per 100 g

The table uses USDA FoodData Central entries. The skyr row is one branded product (Agri-Star, plain, ingredients: pasteurized organic skim milk and live yogurt cultures), so other brands will differ. Always check the label.

Plain product kcal Protein (g) Fat (g) Carbs (g) Calcium (mg)
Skyr (one brand) 48 8.81 0 2.64 84
Yogurt, whole milk 78 3.82 4.48 5.57 126.8
Greek yogurt, nonfat 61 10.3 0.37 3.64 111

Does skyr have more protein than yogurt?

Compared with plain whole-milk yogurt, yes: 8.81 g against 3.82 g per 100 g in these entries. Compared with nonfat Greek yogurt (10.3 g), no. Protein depends on the product, not only on the name.

Which has less fat?

The skyr entry lists 0 g fat, whole-milk yogurt 4.48 g and nonfat Greek yogurt 0.37 g per 100 g.

How is skyr made?

We did not find an official page (USDA, FDA) that defines skyr, so we do not describe its method or call it a cheese or yogurt. Only the ingredient list above comes from the database.
