Nutritional determinants of mobility.

PURPOSE OF REVIEW: 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 FINDINGS: 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.

SUMMARY: 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.
