Two new studies help to show the power of nutrition to assist allergies and asthma. In one study people with higher levels of folic acid in their blood had had fewer IgE antibodies, fewer reported allergies, less wheezing and lower likelihood of asthma. In another study researchers found that lower blood levels of vitamin D in children were linked to allergy and asthma severity.
There is a national epidemic of asthma in children, in part due to obesity and in part due to the overuse of antibiotics that has caused an overgrowth of Candida, in turn causing excessive production of airway inflammatory signals coming from the Candida.
Nutrients are certainly important and low levels of key nutrients may allow such problems to manifest. Magnesium has long been known to be lacking in individuals with allergies and asthma. Vitamin C and bioflavonoids, especially quercetin, are of immense help.
In the new folic acid study researchers look at medical records of 8,000 people ages 2 to 85, comparing folic acid blood levels to levels of IgE antibodies, a key immune system marker that elevates to an allergen. People with higher blood levels of folate had fewer IgE antibodies, fewer reported allergies, less wheezing and lower likelihood of asthma. The researchers believed that folic acid was acting to help reduce inflammation.
Our findings are a clear indication that folic acid may indeed help regulate immune response to allergens, and may reduce allergy and asthma symptoms, says lead investigator Elizabeth Matsui, M.D. M.H.S., pediatric allergist at Hopkins Childrens.
In the new vitamin D study the researchers found that children with lower vitamin D levels were significantly more likely to have been hospitalized for asthma in the previous year, tended to have airways with increased hyperreactivity and were likely to have used more inhaled corticosteroids, all signifying higher asthma severity. These children were also significantly more likely to have several markers of allergy, including dust-mite sensitivity.
It appears that nutrient deficiencies of common nutrients set the stage for excessive inflammatory reactions, which include allergy and asthma. Parents should obviously improve the quality of the diet of any child with such a problem.
