Symptoms vary but include skin rashes gastrointestinal problems.
Rarely does life-threatening anaphylaxis ocur. The best course of action is complete avoidance of the food causing the allergy. My toddler was recently diagnosed with a soy allergy. This a.m. he had a serious reaction from eating peanutbutter chips and I had to give him benadryl. I am trying to locate information regarding soy allergies in kids.
