免疫力,即人体对疾病的抵抗力,是机体防衰老的一种保护性功能。老年人随着年龄增长,机体趋于衰弱,常会发生某些老年病,如动脉硬化、高血压、冠心病、糖尿病、肿瘤,以及老年性感染等,这往往都与免疫功能降低有关。因此,老年人应当注意保护好自身的免疫功能,增强抗病能力,预防老年性疾患的侵袭。怎样才能保护和增强老年人的自身免疫力呢? 合理营养:现代科学表明,平衡膳食,合理营养,是延缓衰老达到健康长寿的先决条件。要提高老年人的免疫力,首先必须重视各种营养素的补充,在诸多的营养成分中,更以补充蛋白质为最重要。营养不良,特别是蚕白质营 Immunity, the body’s resistance to disease, is a protective function of the body against aging.
