7 signs your child may have a food intolerance
6. Crankiness
Possible culprit: Gluten intolerance. Gluten sensitivity is traditionally associated exclusively with digestive disturbances, but some studies have recently linked it to neurological symptoms, which can range from moodiness and chronic headaches to ADHD and coordination loss.
Action plan: Eliminate gluten for a month to assess a connection between mood and food. Other reasons may account for kids’ agitation; however, if food is the culprit, says Dorfman, children will often want to eat the problem food excessively.
