Diet or DNA: Are Food Allergies Genetic?

Food Allergies & Genes

As we have explored in our past blogs, there are a number of physical and behavioral traits that are determined by your DNA.

But are you aware of how genetics can determine food allergies, too?

Today, we’re exploring how allergies can come to affect an individual, and how much DNA plays into it.

Food Allergies & Your Genes

In general, the tendency for developing allergies is hereditary. However, the presence of food allergies in mother and father does not always translate into food allergies in the child.

Also, in many cases, it is the likelihood of having the food allergy that is inherited, not the actual food allergy itself.

Peanut Allergies

Researchers at the Johns Hopkins Bloomberg School of Public Health found that one genomic region on chromosome six is linked to peanut allergies, connected to 20% of peanut allergies in the study population. Genes such as HLA-DB and HLA-DR are contained in this region.

Immunoglobin E Production

Allergic responses are triggered by the body’s production of active immunoglobulin E, or IgE. This antibody travels to certain cells and makes them release chemicals that cause allergic reactions.

Some people produce active IgE due to specific human leukocyte antigen, or HLA, genes, which are part of the immune system.
