In this week's "What's Ailing You," News 12 Connecticut met up with some younger viewers in Norwalk who are curious about food allergies.

The kids say that they are aware of food allergies because their school prohibits peanut butter or any other foods containing nuts at certain tables in the cafeteria.

Dr. Mitchell Lester, of Fairfield County Allergy, says kids outgrow these allergies about 20 percent of the time. He says the only way to tell if a child has outgrown a food allergy is to let them eat the food in question, but under the supervision of a medical professional.

"Very often, we'll do a food challenge here in the office," said Lester. "Give a person a little bit...and if there's a reaction, we treat it."

Lester says he first performs a blood test to check on the likelihood that a child has outgrown their allergy.
