New Study Shows Folic Acid May Reduce Allergies
While there is no better way to manage allergies than preventing contact with the allergen, a new research from Johns Hopkins Children Center indicates that folic acid (vitamin B9) may reduce allergies. The study found out that people with higher levels of folic acid in their blood are less prone allergies.
About 25 million Americans suffer from allergies, according to U.S. Center for Disease Control and Prevention. Allergies are caused due to improper immune response to matters such as pollen, dander, food etc. Allergic individuals, along with preventive measures, can also take up allergy shots or immunotherapy treatment for managing allergies.
The researchers from Johns Hopkins Children Center analyzed the medical records of over 8000 people between the ages 2 to 85, to know the effect of folic acid levels on allergic symptoms.
The researchers found out that people with high levels of folic acid in their blood had fewer reported allergies and fewer IgE antibodies.( Fewer IgE antibodies in the blood indicate low risk of allergies). This study shows that high levels of folic acid in blood decreases the risk of allergies.
According to the researchers, further studies should be done to know the mechanism behind folic acid decreasing allergic symptoms Studies should also be done to know if folic acid supplementation can help in reducing asthma and allergic symptoms.
This study may encourage those with allergies to increase the folic acid intake, which is present in leafy vegetables, nuts and beans.
