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.
Adequate protein intake is required for the maintenance of whole-body protein mass. The protein mass in a 70 kg adult is about 11 kg. Whole-body protein mass maintenance relies on equal rates of protein synthesis and breakdown, resulting in a zero net balance.
1 maj 2018 · Moore et al. (28) compiled data from 6 studies to obtain postprandial body weight–normalized MPS rates over a wide range of protein intakes in 65 younger and 43 older individuals. Biphasic linear regression was performed to determine the relative protein dose required to maximally stimulate MPS.
Research shows that higher dietary protein of up to 1.2 g/kg bodyweight /day may help prevent sarcopenia and maintain musculoskeletal health in older individuals. Achieving higher daily dietary protein levels is challenging, particularly for older adults with declining appetites and underlying health conditions.
4 cze 2024 · Protein supplementation has shown to improve muscle mass in older adults. However, its effect may be influenced by supplementation dose, frequency and timing. This systematic review aimed to assess the effect of dose, frequency and timing of protein supplementation on muscle mass in older adults.
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.
