Ingesting small amounts of peanut protein can lower risk of peanut allergy, says new study
Worried about peanut allergies in children? There may be some simple steps to keep your child away from possible catastrophe because of accidental ingestion of an allergen.
A practice article in CMAJ (Canadian Medical Association Journal) outlines five things to know about early introduction of peanuts in infants to reduce the risk of peanut allergy.
- Infants who are fed peanut protein regularly have a lower risk of peanut allergy.
- To prevent peanut allergy, peanut protein (such as peanut butter or powdered puff) may be introduced at home for most babies between 4 and 6 months as one of the first foods.
- Babies with severe eczema are more likely to have peanut allergy, and those with no or only mild eczema are best-suited for peanut introduction in the home.
- Infants with risk factors for peanut allergy, such as severe eczema, egg allergy or both, should be seen by a specialist before peanut introduction.
- To reduce the risk of peanut allergy, 8 grams of peanut protein (1 heaped teaspoon of peanut butter) should be eaten at least twice a week.
According to the Mayo Clinic, “Peanut allergy is one of the most common causes of severe allergy attacks. Peanut allergy symptoms can be life-threatening (anaphylaxis). For some people with peanut allergy, even tiny amounts of peanuts can cause a serious reaction. Peanut allergy has been increasing in children. Even if you or your child has had only a mild allergic reaction to peanuts, it’s important to talk to your doctor. There is still a risk of a more serious future reaction.”
The symptoms of peanut allergy include runny nose, skin reactions, such as hives, redness or swelling, itching or tingling in or around the mouth and throat, digestive problems, such as diarrhoea, stomach cramps, nausea or vomiting, tightening of the throat and shortness of breath or wheezing.
