Food allergies in children: Pediatric guidelines, diagnosis and more

Food allergies are a fairly common concern for parents. When their children are young. But how common are food allergies? Could your child have a food intolerance instead of a true food allergy? Will they outgrow their food allergy.

How common are food allergies?

True food allergy affects about 4-8% of children, and some grow out of it. As a result, food allergies affect about 2-5% of adults. There’s been a significant increase of food allergies in the last 10 years or so. There are a few theories for this rise, and it’s likely a combination of these theories that’s contributing to the rise in food allergies:

  • One is the hygiene hypothesis. This asserts that because the environment has become cleaner and we’re disinfecting things more regularly, kids’ immune systems aren’t as distracted by responding to frequent infections. Instead of responding to those infections, their bodies may respond by developing new allergies instead.
  • Another theory is that children are exposed to food proteins through the skin. Children can then become sensitized to that allergen, and it can cause a response later when they eat the food.
  • A third theory is attributed to pediatric guidelines from many years ago that advised children shouldn’t be introduced to historically allergenic foods at a young age. Not having these foods in kids’ diet early on may have contributed to the rise of allergies.

Food allergy vs. food intolerance

It’s estimated that about 35% of patients and/or parents report a food reactivity or intolerance. Which they believe is a true food allergy. The child may have nausea ยูฟ่าเบท or diarrhea or another reaction that looks like it could be allergies, such as a rash around the mouth. If your child has experienced any of these reactions with no other symptoms, it may not be a true food allergy. You should discuss this with your child’s pediatrician.

True food allergy can be reproduced when eating a certain food. A child typically doesn’t have a reaction the first time they eat a food. Peanuts are an exception to this because, most likely, the child has already been sensitized through their skin or some other way.
