Low concentration of vitamin E in the blood is linked with physical decline in older persons, Scientist from Yale School of Medicine found.
In the research, they collected blood samples of 698 people age 65 or older to measure the levels of micronutrients including folate, iron and vitamins B6, B12, D and E. After that, they assessed physical decline in the study participants over a three-year period using an objective test. The evaluation to the research found that the odds of declining in physical function was 1.62 times greater in persons with low levels of vitamin E compared with persons with higher levels.
The first author of Yale, Benedetta Bartali added, it is unlikely that vitamin E is simply a marker for poor nutrition, because the researches done were independent of energy intake, and the effect of low levels of other micronutrients was not significant.
According to the result, the researchers suggest that an appropriate dietary intake of vitamin E may help to reduce the decline in physical function among older persons.
On the other hands, vitamin E was the only antioxidant measured in the study. So, further studies are needed to determine whether low levels of other antioxidants would yield the same results, just like Bartali told ScenceDaily.
