需要足够的膳食蛋白质摄入来延缓和治疗老年人的肌肉减少症。需要深入了解这一异质人群的膳食蛋白质摄入量，以确定膳食不足，并确定目标人群和膳食干预的喂养策略。因此，我们评估了荷兰社区居住、体弱和机构化老年人的膳食蛋白质摄入量、全天蛋白质摄入量分布以及含蛋白质食物来源的使用。和机构老年人，以评估蛋白质摄入量的特点。膳食蛋白质摄入量平均为1.1 +/- A 0.3 g/kg-bw/天，在社区居住，体弱者为1.0 +/-0.3 g/kg-bw/d，机构老年男性为0.8 +/-0.3 g/kg-bw/d。在女性中也发现了类似的蛋白质摄入量。10%的社区居住和体弱老年人和35%的机构老年人的蛋白质摄入量低于估计的平均需求量（0.7 g/kg-bw/天）。社区居民早餐蛋白质摄入量特别低，（10 +/- A 10 g），虚弱（8 +/-A5 g），以及机构化老年人（12 +/-A6克），以面包和奶制品为主要蛋白质来源。而社区居住和体弱的老年人每日蛋白质摄入量通常远高于建议的膳食摄入量，很大一部分养老院老年人的蛋白质摄入量低于目前的需要量，使他们成为饮食干预的重要目标人群。特别是在早餐时，有改善蛋白质摄入量的余地。
Adequate dietary protein intake is required to postpone and treat sarcopenia in elderly people. Insight into dietary protein intake in this heterogeneous population segment is needed to locate dietary inadequacies and to identify target populations and feeding strategies for dietary interventions. Therefore, we assessed dietary protein intake, distribution of protein intake throughout the day, and the use of protein-containing food sources in community-dwelling, frail, and institutionalized elderly people in the Netherlands.Secondary analyses were carried out using dietary data collected from studies among community-dwelling, frail, and institutionalized elderly people to evaluate protein intake characteristics.Dietary protein intake averaged 1.1 +/- A 0.3 g/kg-bw/day in community-dwelling, 1.0 +/- A 0.3 g/kg-bw/day in frail, and 0.8 +/- A 0.3 g/kg-bw/day in institutionalized elderly men. Similar protein intakes were found in women. Ten percent of the community-dwelling and frail elderly and 35% of the institutionalized elderly people showed a protein intake below the estimated average requirement (0.7 g/kg-bw/day). Protein intake was particularly low at breakfast in community-dwelling (10 +/- A 10 g), frail (8 +/- A 5 g), and institutionalized elderly people (12 +/- A 6 g) with bread and dairy products as predominant protein sources.Whereas daily protein intake is generally well above the recommended dietary allowance in community-dwelling and frail elderly people, a significant proportion of institutionalized elderly showed an intake below the current protein requirement, making them an important target population for dietary interventions. Particularly at breakfast, there is scope for improving protein intake.
