However, there are vastly different opinions on how much protein we actually need. Most official nutrition organizations recommend a fairly modest protein intake. The DRI (Dietary Reference Intake) is 0.8 grams of protein per kilogram of body weight, or 0.36 grams per pound. This amounts to: 1  56 grams per day for the average sedentary man.  46 grams per day for the average sedentary woman.
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.
