Cheese is basically 58% protein by calorie. Not many foods in the aisle read that clean.

Cottage cheese, skyr, and canned tuna hit the same range. Most things marketed as "high protein" land in the 30–45% band.

The chef's caveat

Plain vs. flavored

Numbers on this page are for plain, unsweetened. Flavored versions typically add 8–18g of sugar per container — sometimes more than a scoop of ice cream. Read the panel; the difference is not small.

About 48 calories, with roughly 6.8g of protein. slice (1 oz) weighs about 28g. Use the slider above for any other portion.

Nonfat vs. full-fat — which is better?

Depends on the goal. Nonfat: max protein per calorie, best for a cut. Full-fat: more satiating, some studies link it to better metabolic markers, and it tastes better. Neither is "wrong."

Is cheese actually healthy, or is that marketing?

By the numbers on this page: high protein, low fat, near zero sugar. Hard to argue with.
