Mealtime may get a bit easier for parents of the four million US children who suffer from food or digestive allergies. According to The Wall Street Journal, many tots who have been diagnosed with allergies based on blood or skin tests may not actually be allergic to those items. When tested with a food challenge in a doctor's office or hospital, parents may find that their lil one can in fact tolerate the food in question.

At the American Association of Allergy, Asthma and Immunology (AAAI) conference last year, doctors from National Jewish reported that of 125 young patients given food challenges, more than half could tolerate foods they'd been told to avoid.

While knowing the history of what a child has eaten may be the most important part of initially diagnosing an allergy, food challenges, during which a child comes in contact with a food item while under a doctor's supervision, appear to be the best way to determine a true allergy. But parents who fear a full-on anaphylactic reaction tend to shy away from such experiments.

If your child had a food allergy, would you consider a food challenge to determine the severity of the problem?
