心衰?多喝点甜菜根汁吧,有好处据发表于 Circulation: Heart Failure的一项研究表明,高硝酸盐(甜菜根汁中可大量发现)饮食可改善心衰患者的肌肉功能。硝酸盐是甜菜汁,菠菜及其他绿叶蔬菜(如芝麻菜和芹菜)的活性成分。研究人员曾发现,摄入高水平的硝酸盐可改善体育精英的肌肉性能。此次研究旨在探究甜菜汁是否有益于心衰患者的健康。研究仅纳入了9名患者,均接受甜菜汁治疗。采用双盲、自身对照

据发表于 Circulation: Heart Failure的一项研究表明,高硝酸盐(甜菜根汁中可大量发现)饮食可改善心衰患者的肌肉功能。

硝酸盐是甜菜汁,菠菜及其他绿叶蔬菜(如芝麻菜和芹菜)的活性成分。研究人员曾发现,摄入高水平的硝酸盐可改善体育精英的肌肉性能。此次研究旨在探究甜菜汁是否有益于心衰患者的健康。

研究仅纳入了9名患者,均接受甜菜汁治疗。采用双盲、自身对照法;一些患者的甜菜汁中去除了硝酸盐,作为安慰剂对照组。

结果发现,饮用含硝酸盐的甜菜汁后2小时,患者伸膝时其肌肉力量增加了13%,速度最快时,肌肉增加的力量也最大。

通过对比患者锻炼中肌肉力量的改善情况,研究人员评估了甜菜汁所带来益处的大小。

Andrew R. Coggan教授对比了甜菜汁对吃菠菜的大力水手的作用,发现甜菜汁对肌肉性能的改善程度相当于心衰患者做了3个月的阻力训练。

基于越来越多的关于硝酸盐对健康人及运动员作用的研究以及目前关于心衰患者的研究,研究人员欲探究硝酸盐对老年人的作用。

老化的其中一个问题就是肌肉变弱、速度变慢、力量变小。超过一定年龄后,肌肉功能每年都会减小1%。如果正如本研究所做的那样提高肌肉的力量,那么便可以为老年人带来明显地益处。
