list of foods containing casein
Whey protein is rich in both glutamineâthe most abundant amino acid in muscleâand branched-chain amino acids, which can fuel working muscles during exercise. One of the best dietary sources of whey protein: ricotta cheese. Casein makes up 80% of the protein found in milk. Itâs found in higher concentrations in cottage cheese and Greek yogurt. Caseinâs unique effects arise from how itâs absorbed and digested. Unlike whey, casein is absorbed slowly, increasing but not spiking blood amino-acid levels.
