Protein gets talked about like it has one job: build muscle.
But once you eat protein, your body breaks it down into amino acids, and those amino acids have a much longer job description.
They’re involved in building and repairing tissues, making enzymes and hormones, supporting immune function, and producing proteins your body uses to transport substances throughout the body.
And unlike fat or carbohydrate, your body doesn’t have a large dedicated storage system for extra protein.
That’s part of what makes protein needs more nuanced than simply looking for the biggest number of grams on a label.
How much you need can depend on things like your age, body size, activity level, health, and goals. And the foods providing that protein still matter too.
So yes, protein is important.
But understanding what your body actually does with it gives that “20g protein” label a little more context.
