蛋白质营养不良

维持强健健康晚年生活的最佳膳食蛋白质
蛋白质营养不良是老年人中普遍存在的问题^1,2。这种情况对发病率、死亡率、生活质量以及医疗费用都有各种负面影响^2-4。

乳清蛋白被广泛认为是可用的最高质量的蛋白质来源之一⁵。它超过了联合国粮食及农业组织制定的成人必需氨基酸要求⁶。此外，乳清蛋白中亮氨酸的高比例使其成为肌肉蛋白合成的有力刺激因子，从而有助于抵消肌肉质量的损失⁷。

乳清蛋白——支持少肌症的饮食管理
肌萎缩症是一种以骨骼肌质量和功能逐渐丧失为特征的综合征，可影响所有年龄段的人，但在老年人中更常见⁸。肌萎缩症对整体生活质量有很大影响，并可能导致跌倒、住院、住院，甚至死亡^9，10。为了增强骨骼肌质量，确保摄入足够的高质量蛋白质是有益的，如乳蛋白^11，12。乳清蛋白刺激肌肉蛋白合成代谢的强大能力归因于其丰富的必需氨基酸，如支链氨基酸（BCAAs）和亮氨酸，以及其快速消化⁷。

阿拉食品原料有广泛的乳清成分，可用于医学营养，针对蛋白质营养不良和少肌症的饮食管理。查看我们的产品组合。
