In many countries, persons over 65 are one of the fastest growing segments of the population. Mobility disability is one of the major risk factors for morbidity and mortality in this age group. There is increasing evidence that improved nutrition can reduce the risk of developing disability in older age. This review summarizes the recent literature showing the associations between different nutrients and mobility-related outcomes in older adults.
Recent studies suggested an association between low intake and low serum concentrations of micronutrients, such as antioxidants and vitamins, with measures of physical performance, muscle strength, and disability in older adults.
The role of low micronutrients as cross-sectional and longitudinal correlates of mobility disability is consistent with a growing number of studies showing that a diet rich in fruits and vegetables, such as the Mediterranean diet, has a beneficial role in healthy aging.
在许多国家，65 岁以上人群是人口增长最快的群体之一。行动障碍是该年龄段发病率和死亡率的主要危险因素之一。越来越多的证据表明，改善营养可以降低老年人残疾的风险。本综述总结了最近的文献，这些文献表明不同营养素与老年人的移动相关结局之间存在关联。
最近的研究表明，微量营养素（如抗氧化剂和维生素）的摄入量和血清浓度低与老年人的身体表现、肌肉力量和残疾测量值有关。
低微量营养素作为行动障碍的横断面和纵向相关因素，与越来越多的研究结果一致，这些研究表明，富含水果和蔬菜的饮食（如地中海饮食）对健康衰老具有有益作用。
