High protein dairy
These are the dairy foods that give you the most protein for every calorie, ranked by grams of protein per 100 kcal, with soy milk in for comparison.
Numbers for the portion shown, the same as on each food's page. Sports are for someone of about 70 kg.
Whey is at the top, and right behind it are skyr and quark, which are about as close to a protein shake as a spoonable food gets.
Cottage cheese and Greek yoghurt are next. Hard cheese like parmesan has loads of protein too, but it brings more fat, so it ranks lower.
A pot of skyr or quark a day is one of the easiest protein habits there is, and most supermarkets have both now.
