High-Fiber Diet Alters Gut Bacteria to Protect Against Food Allergy

A high-fiber diet rich in vitamin A may alter gut bacteria in a way that could prevent or reverse food allergies. This is the finding of a new study published in the journal Cell Reports.

It is estimated that around 15 million people in the United States have food allergies, and this number is increasing.

According to the Centers for Disease Control and Prevention (CDC), between 1997-2007, the number of children and adolescents in the U.S. with food allergies rose by around 18 percent, though the reasons for this are unclear.

Eight food types account for around 90 percent of all food allergies. These are peanuts, tree nuts, egg, milk, wheat, soy, fish, and shellfish.

Allergic reactions to food vary from person to person, but they may include tingling or itching in the mouth, hives, nausea or vomiting, stomach pain, and diarrhea.


Researchers say a high-fiber diet enriched with vitamin A shows promise for reducing the risk of
food allergy.
