DSM study shows most US adults have low vitamin E status
Vitamin E is a powerful antioxidant and carries an approved EFSA health claim for ‘contributing to the protection of cells from oxidative stress2. Vegetable oils, nuts, and seeds, along with fortified cereal and green leafy vegetables are significant dietary sources of vitamin E. The research was conducted because more than 90% of American adults do not eat the recommended dietary intake (15 mg/day) of vitamin E from food, with the caveat that it may be hard to account for sources such as vegetable oils3.
Study results found lower average α-tocopherol levels in people who do not use dietary supplements, even when adjusted for total cholesterol. Among those depending exclusively on food sources, 93% of 20-30 year olds, 81% of 31-50 year olds, and 81% of individuals over 51 years old had suboptimal vitamin E status. Lower proportions were observed among individuals reporting dietary supplement use (79% of 20-30 year olds, 54% of 31-50 year olds, and 29% for those over 51 years old). Older adults had lower proportion of inadequate serum α-tocopherol concentrations.
Senior author, Dr. Saurabh Mehta, a faculty member at Cornell University says: “These findings indicate that it is important to conduct further research to elucidate the association of serum α-tocopherol concentrations with specific health outcomes.”
Co-author Manfred Eggersdorfer, Senior Vice President, Nutrition, Science & Advocacy at DSM and Professor for Healthy Ageing at Groningen University, comments: “We have known for years that vitamin E intake of Americans was significantly below the Institute of Medicine4 recommendation of 15 mg daily. 87% of all 20-30 year olds, and 93% if they do not use a supplement, have serum α-tocopherol concentration below 30 µmol/L.”
Michael McBurney, VP Science, Scientific Communications and Advocacy at DSM adds: “Epidemiological studies indicate that maintaining serum α-tocopherol may help maintain reproductive, brain, and liver function.”
