The European Food Safety Authority recently estimated that the Population Reference Intake for adults of all ages was 0.83 g protein/kg body weight per day. The Reference Nutrient Intake (RNI) in the UK for protein in the healthy adult (including older people) population is 0.75g/kg body weight. Requirements are determined by measurement of the amount of protein needed to maintain nitrogen balance and provide any additional needs for growth, pregnancy and lactation. In healthy individuals with nutritionally complex diets, protein intakes are generally higher than requirements. However this is not the case for older subjects, particularly those living in institutions.
