High intake of dietary vitamin E may reduce dementia risk
Font size:
A recent study published in Archives of Neurology suggests that having high intake of dietary vitamin E may help prevent dementia.
The study found people who had high intake of vitamin E were 25 percent less likely to develop dementia.
For the study, Elizabeth E. at Erasmus Medical Center in Rotterdam, the Netherlands and colleagues followed 5395 participants aged 55 or older who were free of dementia at baseline for about 10 years and identified 465 cases of dementia including 365 cases of Alzheimer's disease.
After adjustment for confounders including age, education, apolipoprotein E 4 genotype, total energy intake, alcohol intake, smoking habits, body mass index, and supplement use, higher intake of dietary vitamin E at baseline was associated with lower long term risk of dementia.
Specifically, those who were in the highest tertile of vitamin E intake were at 25 percent reduced risk of dementia, compared to those in the lowest tertile.
However, intake of dietary vitamin C, beta carotene and flavonoids were not correlated with dementia risk after adjustment for confounders.
The associations were similar for Alzheimer's disease.
The researchers concluded Higher intake of foods rich in vitamin E may modestly reduce long-term risk of dementia and Alzheimer's disease.
