A corn allergy? Does that even exist? Yes you can be allergic to corn and it is a nightmare to avoid! Since corn is in almost 75% of processed food and about 50% of sweeteners, living the corn free life is a challenge . Our daughter tested a four out of five to corn which means we are to avoid everything that has corn in it, or derives from corn. Everything from artificial flavoring to carmel coloring has corn in it, Most baking products such as baking powder and powdered sugar have corn startch in them, and lets be honest corn syrup is in everything and anything edible now days!
The scary part is it’s hard to know exactly how food is processed. For example gluten can come from corn, but not always. The only safe way to handle a true severe corn allergy is to make everything from scratch and avoid eating out.
