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.
The Institute of Medicineâs protein RDAs are calculated using 0.8 grams of protein per kilogram of body weight. This means an adult who weighs 68 kilograms needs at least 54 grams of protein each day. The RDA for pregnant and nursing women is 71 grams of protein per day. Active adults and elderly people likely require more protein than the RDA of 0.8 grams per kilogram.
