Alpha-Tocopherol: A Food Allergy Shield
Did you know that a form of vitamin E could protect your child from severe food allergies? In this blog, we’ll explore how alpha-tocopherol, a standout variant of vitamin E—might be the key to preventing food allergies early in life. You’ll learn about a groundbreaking study, the science behind these benefits, and how everyday choices might impact your family’s health.
A Promising Discovery in Allergy Prevention
A recent study in mice by researchers at the Indiana University School of Medicine has revealed that alpha-tocopherol, a form of vitamin E, may help reduce the development of food allergies. Published in the Journal of Immunology, the study suggests that increasing this vitamin during and after pregnancy might offer protective benefits for infants and children
Led by Joan Cook-Mills, PhD, a professor of paediatrics at IU School of Medicine, the research team discovered that when mouse mothers had higher levels of alpha-tocopherol in their diets, their offspring experienced fewer allergy issues. As Dr. Cook-Mills stated,
“Since food allergies most often develop early in life, prevention at this stage is crucial. Our findings suggest that increasing alpha-tocopherol consumption — through prenatal vitamins during pregnancy, infant formula adjustments or other dietary supplements — could help reduce the risk of children developing food allergies.”
How Does Alpha-Tocopherol Work?
The study used mouse models to examine the effects of alpha-tocopherol on allergy development.
- Newborn mice exposed to common food and skin allergens developed allergies; however, those whose mothers consumed higher levels of alpha-tocopherol were significantly protected from developing these reactions.
- This research points toward the potential of using dietary adjustments during pregnancy and nursing to lower the risk of severe allergies in children.
The Cooking Oil Conundrum: Alpha vs. Gamma Tocopherol
Interestingly, previous research from the Cook-Mills lab found that gamma-tocopherol—another variant of vitamin E, can counteract the benefits of alpha-tocopherol. Gamma-tocopherol is abundant in many cooking oils commonly used in the United States, such as soybean, canola, and corn oils. In contrast, European countries often use oils like sunflower, safflower, and olive oils, which have higher levels of alpha-tocopherol.
Dr. Cook-Mills notes, “Currently, alpha-tocopherol supplementation may have a greater benefit for allergies in European countries, where they use more sunflower, safflower and olive oils.”
She further suggests that U.S. manufacturers might consider adjusting their production processes to reduce gamma-tocopherol and boost alpha-tocopherol levels, potentially enhancing the vitamin’s allergy-preventing properties.
Looking Ahead: Future Research and Impact
The research team, including Allison E. Kosins, Haoran Gao, Ross L. Blankenship, Lauren N. Emmerson, and Joel A. Ochoa, plans to explore how alpha- and gamma-tocopherol influence other allergy-related processes, particularly in premature infants. With support from the National Institutes of Health, this work could pave the way for new dietary recommendations and improved infant formulas aimed at reducing severe allergic reactions early in life.
Key Takeaways
- Alpha-tocopherol may help reduce the risk of developing food allergies when consumed in higher amounts during pregnancy and nursing.
- Gamma-tocopherol, prevalent in many U.S. cooking oils, can negate the benefits of alpha-tocopherol.
- Adjustments in dietary supplements and cooking oil production could further enhance allergy prevention.
