Low vitamin E levels linked to greater physical decline

Low blood levels of vitamin E are linked to greater physical decline in older people, suggests a new study from Yale University School of Medicine. The researchers obtained measures for several micronutrients, including folate, vitamins B6, B12, D and E, but only the last vitamin was associated with physical decline for older persons, they report in the Journal of the American Medical Association. «The current study provides empirical evidence that a low concentration of vitamin E is associated with subsequent decline in physical function in a population-based sample of older persons living in the community». «Although the findings from this epidemiological study cannot establish causality, they provide a solid base that low concentration of vitamin E contributes to decline in physical function» . The researchers go on to propose three mechanisms which could explain the relationship between low vitamin E levels and the decline in physical function: The increased level of oxidative stress could result in damage to muscle or DNA; there could be an exacerbation of atherosclerosis or other pathologic conditions; and an increase in neurodegenerative disorders.
