Can allergies cause stomach cramps? Allergy and health myths debunked

More and more kids are being diagnosed with food allergies – a troubling trend that has been on the rise for the past 15 years.

Studies estimate that about 5 to 8 percent of children have a food allergy. And one major culprit is peanuts, with one in every 50 kids having a peanut allergy.

While it remains unknown exactly why food allergies are on the rise, several theories have tried to explain it:

1. The “hygiene” hypothesis.

Simply put, we’re way too clean, and we keep our children away from normal germs that help strengthen their immune system.

2. Delaying the introduction of high allergen foods.

The delay (which is not prevalent in other countries) might not prepare the developing immune system for new foods.

3. Changes in the food supply.

The way food is grown might impact the potential for an allergic response.

Regardless of the cause, kids and parents needs to know what to do when a food allergy turns up. And importantly, know the differences between food sensitivities, food intolerance, and a true food allergy.

  • If you do not have an allergic reaction, your body may just be intolerant or sensitive to the food.
  • The eight most common food allergies are: Milk, eggs, fish, shellfish, tree nuts, peanuts, wheat and soybeans.

Stomach issues may be a result of a food allergy. Truth or myth?

  • Stomach issues (bloating, cramps, gas) caused by digestive problems are not life threatening.
  • Foods that commonly cause stomach issues are: Milk, gluten, wheat, legumes, soy, garlic, onions and sweeteners.

Once a child is diagnosed with a good allergy, it can never be outgrown. Truth or myth?
