How much protein do we need?
The challenge is that how much protein we need varies depending on age, weight, physical activity and other factors, she said (the Dietary Guidelines say the RDA is 46g/day for women and 56g/day for men, but this is based on 0.8g protein per kilo of body weight per day, so the actual RDA for you may be higher or lower than this. eg. If you if you weigh 91kg or 200lbs, the RDA is 73g of protein).
