In the case of daily protein intake, the EAR for dietary protein is 0.66 g/kg/day and the Food and Nutrition Board recommends an RDA of 0.8 g/kg/day for all adults over 18 years of age, including elderly adults over the age of 65.
After reviewing this evidence, the international study group (PROT-AGE Study Group) of the European Union Geriatric Medicine Society (EUGMS) has recommended an average daily intake of 1.0–1.2 g protein/kg BW per day for older adults.
Owing to age-induced “anabolic resistance”, older people probably require 30–45 gm protein per serving to stimulate muscle protein synthesis after that meal, whereas lower doses (≤20 gm) are sufficient in young adults (see above and ).
This series of articles used pooled data of primarily healthy older adults from a number of large cohort studies and clinical trials to provide evidence-based cutpoints for the diagnosis of sarcopenia.
Collectively, cross-sectional observational studies suggest that protein intake around the international recommendation (0·8 g/kg/d, 60–65 g/d in average-sized individuals, 75–80 kg) is sub-optimal for the maintenance of muscle mass throughout adult life.
18 lip 2013 · To help older people (>65 years) maintain and regain lean body mass and function, the PROT-AGE study group recommends average daily intake at least in the range of 1.0 to 1.2 g protein per kilogram of body weight per day.
