Nutrition is critical to the health of the elderly, since most of them have a deficiency in key nutrient. The use of whey protein may be a food strategy to increase protein intake. The objective of this work was to evaluate the ingestion of whey protein for the elderly and the association with physical performance and clinical outcomes. A systematic review was conducted in order to find papers that shed some light in the correlation between whey protein and the elderly. Inclusion criteria: population: elderly; intervention: use of whey protein when compared to control group; outcome: related to health, nutrition, or quality of life. Database: PubMed, with papers published in the last 5 years. Search strategy: (elder OR senior OR elderly OR aging OR aged OR old OR older) AND (whey OR “whey protein”). 35 papers were selected of which 22 had a physical performance outcome and 13 had clinical outcomes. Studies indicate that whey protein supplements promote protein synthesis in the elderly, improving muscle performance and aerobic capacity, protecting against sarcopenia and reducing the risk for falls. In the papers studied, the age group considered to be elderly was ≥65 years in 27 papers and ≥60 years in the other 8 papers. Whey protein also appears to contribute to improved health, recovery from disease, prevention of cardiovascular and metabolic risks, and hepatic steatosis complications. Data suggest that whey protein supplements may be promising for the health improvement of the elderly.

营养对老年人的健康至关重要，因为其中大多数人缺乏关键营养素。乳清蛋白的使用可能是增加蛋白质摄入量的食物策略。这项工作的目的是评估老年人摄入的乳清蛋白以及其与体能表现和临床结局的关系。为了找到能够阐明乳清蛋白与老年人之间关系的论文，进行了系统的综述。纳入标准：人口：老年人；干预：与对照组相比，使用乳清蛋白；结果：与健康，营养或生活质量有关。数据库：PubMed，最近五年发表论文。搜索策略：（老年人或老年人或老年人或老年人或老年人或老年人或老年人）和（乳清蛋白或“乳清蛋白”）。选择了35篇论文，其中22篇具有物理表现结果，而13篇具有临床结果。研究表明，乳清蛋白补充剂可促进老年人的蛋白质合成，改善肌肉性能和有氧运动能力，防止肌肉减少症，并降低跌倒的风险。在所研究的论文中，27篇论文中被认为是老年人的年龄组≥65岁，其他八篇论文中被认为是≥60岁。乳清蛋白似乎也有助于改善健康状况，疾病康复，预防心血管和代谢风险以及肝脂肪变性并发症。数据表明，乳清蛋白补充剂可能有望改善老年人的健康状况。改善肌肉性能和有氧运动能力，防止肌肉减少症并降低跌倒的风险。在所研究的论文中，27篇论文中被认为是老年人的年龄组≥65岁，其他八篇论文中被认为是≥60岁。乳清蛋白似乎还有助于改善健康状况，疾病康复，预防心血管和代谢风险以及肝脂肪变性并发症。数据表明，乳清蛋白补充剂有望改善老年人的健康状况。改善肌肉性能和有氧运动能力，防止肌肉减少症并降低跌倒的风险。在所研究的论文中，27篇论文中被认为是老年人的年龄组≥65岁，其他八篇论文中被认为是≥60岁。乳清蛋白似乎也有助于改善健康状况，疾病康复，预防心血管和代谢风险以及肝脂肪变性并发症。数据表明，乳清蛋白补充剂有望改善老年人的健康状况。预防心血管和代谢风险以及肝脂肪变性并发症。数据表明，乳清蛋白补充剂有望改善老年人的健康状况。预防心血管和代谢风险以及肝脂肪变性并发症。数据表明，乳清蛋白补充剂有望改善老年人的健康状况。
