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.
Studies show that 12 percent of men and 24 percent of women over age 70 eat significantly less than 0.8 g/kg a day. These higher recommendations do not translate into a lot of extra protein. To figure out how much protein you'd need, take your weight in pounds and multiply it by 0.45. Then multiply by 1.2 to reach the recommended grams of protein per day. For a person who weighs 200 lb (90 kg), this would equal about 108 g of protein daily. Most meat, poultry and fish have about 7 grams of protein in an ounce. One cup of milk or one egg has about 8 grams.
