There's been an increase in allergies that the government can't explain.

FOX News Radio's Ron Flatter reports:

About one out of every twenty American children has a food allergy. About fifteen years ago, it was closer to one-in-forty. And the Centers for Disease Control, which just published the report, say they can't explain the increase.

Some allergies are more pronounced than others. The ones like eczema that affect the skin are up 69%. One-in-eight kids gets that. But the allergies that make them sneeze? Pretty much unchanged over the years.

The CDC offers a couple ideas on the increases. That children are coming from cleaner homes, making them more sensitive to the causes of allergies or that parents are just reporting them more.
