If it feels like more kids in your child's class have food allergies, you're not imagining it. A look at national survey data shows the percentage of children in the U.S. with a food or digestive allergy has climbed. In 2007, about 4 out of every 100 kids were reported to have one. By 2018, that number had grown to roughly 6.5 out of every 100 children.
This information comes from the National Health Interview Survey, which asks parents about their children's health. It tells us that more families are dealing with the realities of food allergies, from reading labels to carrying epinephrine auto-injectors. The survey didn't track which specific allergies are increasing or look at how severe the reactions were.
It's important to understand what this data can and can't tell us. Because it's an observational survey, it confirms a trend is happening but doesn't explain the cause. We don't know if more kids are truly developing allergies, or if awareness and diagnosis have simply improved. The survey also relies on parent reports, not doctor-confirmed diagnoses.
The takeaway is clear: food allergies are affecting a growing share of American children. This underscores the need for continued awareness and support in schools and communities. However, the 'why' behind the increase remains a critical question for future research to tackle.
