更长寿
健康医疗知识不断普及、医疗技术持续进步,人类平均寿命达到历史新高。
与此同时,世界卫生组织欧洲区域 60 岁及以上人口数量快速攀升:2021 年为 2.15 亿,预计 2030 年增至 2.47 亿,2050 年将突破 3 亿。其中最需要照护支持的80 岁及以上高龄人群数量到 2050 年将翻倍,给医疗养老体系带来更大压力2。
改善肌肉健康状况
衰老会带来多项身体机能变化,其中之一便是肌少症,表现为骨骼肌量与肌肉功能自然衰退。肌少症可能严重影响人体行动能力、生活质量,甚至缩短预期寿命。 好消息是,日常补充乳清蛋白并配合规律锻炼,能够延缓肌肉量与肌力流失。三项独立人体临床试验3,4,5显示,在坚持抗阻训练的老年女性中,摄入阿拉食品原料的水解乳清原料 Lacprodan® HYDRO.Rebuild,有助于改善与肌少症相关的身体状况。
试验结果表明,摄入乳清的女性健康状况有显著改善,包括:
- 肌肉量增加
- 肌肉力量提升
- 行动灵活度提升
- 腰围减小
- 体脂减少

为何乳清如此特殊?相较于其他蛋白来源,乳清蛋白更能促进老年人肌肉合成6, 7, 8。核心原因在于其亮氨酸含量更高、吸收速度更快;同时能以人体易于消化吸收和利用的形式,提供全部必需氨基酸。
补充蛋白,维持强健体魄
目前,蛋白质的推荐膳食摄入量为每日每公斤体重 0.8 克;但很多老年人的蛋白质摄入量未达到建议水平。荟萃分析显示,约 20%的 老年人蛋白质摄入量低于推荐值,近半数人群未达到适配健康老龄化的较高摄入水平,即每天每公斤体重至少1.0克9。
优质蛋白搭配锻炼,对抗肌少症
越来越多科学证据表明,乳清蛋白可作为优质蛋白补充剂,帮助中老年人在衰老过程中维持肌肉量与肌力10。每日每公斤体重摄入至少 1.2克蛋白质,并保持积极活跃的生活方式,有助于减轻肌少症带来的影响¹¹。
质量胜过数量
常言说 “质优于量”,蛋白补充同样适用这一理念。评判蛋白质品质可采用可消化必需氨基酸评分(DIAAS),该指标综合体现蛋白质的氨基酸组成,以及人体对其的吸收利用率。评分达到 1 及以上,意味着该膳食蛋白质来源能够以易于消化和利用的形式,提供人体所需的全部必需氨基酸(EAA)。
另一种蛋白品质评价标准为蛋白质消化率校正氨基酸评分(PDCAAS),该体系满分上限为 1.0。评分达到 1.0 的蛋白原料,意味着每单位蛋白可满足甚至超额供给人体所需全部必需氨基酸。
这些评分表明,对比市面上常见膳食蛋白原料,乳清蛋白拥有更优质的蛋白品质12, 13, 14,15
