Plant proteins are broken into amino acids and small peptides in the gut, then absorbed and used like any other protein.

Your cells can build many amino acids and assemble new proteins, yet nine amino acids still have to come from food, so diet completes the set.

Most people break down dairy proteins into amino acids without trouble; discomfort is more often tied to lactose, not the protein itself.

A higher-protein eating pattern can reduce hunger, protect lean mass while dieting, and help you hold a calorie deficit without feeling wrecked.

Humans can’t stay healthy without dietary protein because the body needs amino acids to keep tissues repairing and organs running.

Yes, the body digests plant foods into amino acids and uses them to build human protein, including muscle and enzymes.

Humans can nibble grass, but our gut can’t pull out much usable amino acid from it, so grass won’t cover protein needs.

Yes, it can, often from lactose traces, sweeteners, additives, or taking a large serving that pulls water into the gut.

Humans build new body proteins from amino acids, but we can’t create all amino acids ourselves, so some must come from food.

Without dietary protein, the body strips amino acids from muscle and organs, and prolonged severe deficiency can become fatal.
