Food Allergy VS. Food Intolerance
It’s pretty common for children to have a reaction to a certain food, but in most cases it's an intolerance rather than a true allergy. Why does it matter?

Either avoid the food or only have as much as you/your child can have without triggering symptoms.

When eating out, ask your server about how the meal will be prepared. It may not always be clear from the menu whether some dishes contain problem-causing foods.

Learn to read food labels and check the ingredients for trigger-foods. Don't forget to check condiments and seasonings as well; they may contain Monosodium Glutamate (MSG) or another additive that can cause symptoms.
