免疫衰老和老年营养

Immunosenescence and malnutrition in elderly people

免疫系统在衰老过程中发生一系列显著的改变,称为“免疫衰老”,其在老年人的大多数慢性疾病中起着关键的作用。在老年人中,除了免疫系统随年龄增长而发生的内在变化外,老年人更容易出现营养不良,从而进一步影响本已受损的免疫功能。因此,在老年人中重视营养干预,对于促进健康老龄化具有重要的意义。

The immune system undergoes a series of remarkable changes during aging that collectively called"immunosenescence",which plays important roles in most chronic diseases in the elderly.In addition to intrinsic changes in the immune system during aging,aged people are more likely to suffer from malnutrition,which can further compromise already compromised immune function.Therefore,a focus on nutritional interventions among the elderly is very important to promote healthy aging.
