•- Age * 65 years;
•- Community-dwelling;
•- Lower protein intake defined as both a probability score above a certain cutoff on the protein screener (www.proteinscreener.nl) as well as based on actual protein intake assessed by 24-hour recalls. The protein screener was developed and validated using an extended FFQ among Dutch older adults. The cutoff will be chosen based on results of different studies in which we compare the probability scores of the protein screener with protein intake as measured with food diaries and/or dietary recalls. We will then choose the probability score that is most closely associated with a protein intake < 1.0 g/kg body weight/day. This probably score reflects older adults with a higher probability on a protein intake < 1.0 g/kg body weight/d than a general sample of older adults;
