Corn-Free Diet

Confectioners' Sugar Substitute

You don't have to go without cake icing just because of an allergy to the cornstarch in confectioners' sugar (a small amount - 2% - of cornstarch is added to powdered sugar to keep it from clumping). You can make your own confectioner's sugar by placing 1 cup of regular sugar in a blender or food processor and grinding until it is a fine powder. Add 1 teaspoon of arrowroot powder or other starch and use as needed. It should yield about 1 1/2-1 3/4 cups confectioners' sugar (as you powder the sugar in the blender, it increases in volume).

If your child has a sensitivity to corn, you will find it to be a real challenge to avoid. Corn is one of the more versatile substances, being used for everything from food to animal feed, from glue to pharmaceutical applications.

Read food labels for some of the most common corn by-product names, including:

  • Corn flour, cornmeal. corn gluten, cornflakes, etc.
  • Cornstarch, also listed on labels as starch or vegetable starch
  • Corn oil
  • Corn syrup or high fructose corn syrup
  • Dextrins
  • Maltodextrins
  • Dextrose
  • Fructose or crystalline fructose
  • Hydrol, treacle
  • Ethanol
  • Free fatty acids
  • Maize
  • Zein
  • Sorbitol

Tips for Avoiding Corn Products

  • Health food stores often stock corn-free foods, including ketchup, mayonnaise, corn-free baking powder, cereals, etc.
  • Around Passover, corn-free products that are not typically available at other times of the year, are available at kosher stores. Products may include confectioners' sugar made with potato starch, and a special run of name brand soft drinks sweetened with sugar instead of corn syrup. Stock up!
  • Try some of the following alternatives:
    • Rice syrup instead of corn syrup
    • Potato starch, arrowroot powder, tapioca, and other flours as thickeners instead of cornstarch
    • Lemon juice, apple cider vinegar and other non-corn derived vinegars instead of distilled vinegar
  • When purchasing medications or getting a prescription, check with your child's doctor and the pharmacist to make sure the medications are corn-free.
  • Read every label, ask questions and double check with your child's physician.
