While mucus production definitely has an impact on the asthma symptoms of patients, study author Allison Burbank said that the anti-inflammatory effect was likely the most important factor in the study.
Gamma-tocopherol, the type of vitamin E that proved to have these benefits, is found abundantly in walnuts, pecans, and peanuts. Some oils, such as soybean, corn, and sesame, also have significant amounts of the nutrient.
There have been previous studies correlating other types of vitamin E with mitigated asthma symptoms, but this is the first study to link this particular type. These results are a promising sign that there may be more dietary interventions out there for treating and managing asthma. We know that some foods increase your likelihood of an attack, as well, so a few simple changes to a person's diet might make a big difference in their treatment.
