Beware, skin exposure to peanuts may trigger allergic reaction in kids

Did you know allergy to peanuts can be caused without eating them?
According to a study published in the Journal of Clinical Investigation,children may develop an allergic reaction to with skin exposure to peanuts. The study suggests that skin exposure to food allergens may contribute to early sensitisation. In simple words, your skin becomes reactive to antigens resulting in antibody production to the allergens. By repeated exposure, the antibodies trigger allergic reaction. This helps us understand better why peanuts, out of the many foods in our diet, is such a common cause of food allergy. The reason being, skin exposure to peanut allergens early in life contributes to sensitisation.

A few studies in the past have indicated that children may first become allergic to peanuts after exposure through breast milk or house dust.

According to Cecilia Berin, associate professor of pediatrics at the Icahn School of Medicine at Mount Sinai Hospital, peanut protein is recognised as foreign by the immune system. And, it was found that blocking those immune pathways activated in the skin prevented the development of peanut allergy in the mice. The next step would be to confirm this in humans, he explained.

Allergy due to peanuts and other tree nuts such as walnuts, almonds and cashewnuts:

Allergies are common in children and adults who consume plain roasted peanuts and products containing peanuts. About 33% of individuals who have peanut allergy may also show allergic reaction to other tree nuts. According to a report published in the Journal of the Indian Medical Association, peanuts are the most common food allergen in India. Peanut allergy is seen in both adults and children. It is observed that about 9% percent of children suffering tree nut allergy and 20% of children having peanut allergy eventually outgrow their allergy as adults.

Researchers believe that exposing peanuts to high temperature while roasting alters their protein structure which increases the likelihood of allergic reaction. Chances of peanut allergy increase in people having other forms of allergy such as asthma, eczema and hay fever.

How is it recognized?

Common symptoms of peanut allergy include:

• Skin reactions, such as hives, reddening or swelling of skin
• Itchy throat and mouth
