Food allergies less common than parents think, study says

null

It followed more than 900 children from birth to age 3 and found that roughly 5 percent developed a food hypersensitivity based on clinical testing.

In contrast, one-third of parents in the study attributed symptoms like rash, diarrhea and nasal congestion to foods their child had eaten. Parents believed food allergies to be far more common than they actually were.

Researchers say the findings also suggest that food hypersensitivity may not be on the increase as appears to be the case with asthma and hayfever.
