很多人知道老年人需要摄入蛋白质来保持肌肉强健,那怎么吃效果更佳?加拿大麦基尔大学一项研究显示,一日三餐均匀摄入蛋白质或许更有助老人保持肌肉力量。
这项研究基于魁北克地区一项为期三年的营养与老化调查数据。调查涉及1700多名67岁至84岁相对健康的老人。其间,调查对象自行报告两次一日三餐具体内容,并且每年接受一次手部、臂部和腿部肌肉力量测试,以及起立、行走等移动能力评估。研究人员发现,三年下来,老人无论男女,总体体能下降,肌肉力量衰退比移动能力下降更明显。研究人员还发现,那些一天三顿均匀摄入蛋白质的研究对象,在肌肉力量测试中的得分高于那些只在晚餐时食用蛋白质的老人。不过,三餐是否均匀摄入蛋白质与移动能力不存在关联。
美国健康生活新闻网援引研究人员的话报道,只观察到蛋白质摄入分布与肌肉力量之间存在关联,但并非直接的因果关系,“换句话说,我们并不能得出结论说,老年人每顿饭均匀摄入蛋白质,力量一定会更强”。
麦基尔大学这项研究无关蛋白质摄入总量。先前研究显示,成年人应按体重摄入蛋白质,每千克体重对应的蛋白质摄入量为1.2克以上,也就是说,一个重50千克的成年人,一天宜摄入60克以上蛋白质。而老年人由于肌肉蛋白质代谢出现负平衡,宜补充更多蛋白质。
研究结果刊载于最新一期《美国临床营养学杂志》月刊。(黄敏)【新华社微特稿】
