how many grams of protein do i need per day?
You need protein for your muscles, bones, and the rest of your body. Exactly how much you need changes with age: Babies need about 10 grams a day. School-age kids need 19-34 grams a day. Teenage boys need up to 52 grams a day. Teenage girls need 46 grams a day. Adult men need about 56 grams a day.
Wondering exactly how much protein you should be consuming each day? The Recommended Dietary Allowance (RDA), which is the minimum amount you need to be healthy, is 0.8 grams per kilogram (0.36 grams per pound) of body weight per dayâ46 grams for an average woman. That equals as little as 10% of daily calories.
