Cereals allergy recommendations


Like with any food to which they are allergic to, allergic people should carry out a strict diet free from both the cereal and products that may contain it. People allergic to cereals are allergic to their protein and, in theory they tolerate fats extracted from them well. Thus, most people allergic to corn will tolerate corn oil, especially when this is highly refined.

However, we cannot rule out the possible contamination of these oils with residual proteins from the same cereal.



It is always recommended to limit the consumption of industrial products to the maximum and a careful reading of labeling should be made.

When labels show a vegetal product without further specification (vegetable milk, vegetable fat, vegetable broth or stock, etc.) you should avoid the consumption of the product until the exact composition is known.



Wheat products are found in many foods. In order to avoid foods that contain wheat, it is important to read food labels:

  • Be sure to avoid foods that contain any of the following ingredients: bread crumbs, bran, cereal extract, couscous, crackers, enriched flour, flour, gluten, unsifted wheat flour, flour with a high gluten content, flour high in protein, spelt, vital wheat gluten, wheat bran, wheat germ, wheat malt, wheat starch, whole wheat flour.
  • Other ingredients may also indicate the presence of wheat protein: gelatinized starch, hydrolyzed vegetable protein, Kamut (Khorasan wheat), modified food starch, modified starch, natural seasonings, soy sauce, vegetable starch, chewing gums.




To successfully follow a wheat-free diet you should consider the following list of foods that are not allowed:

  • Beverages or drinks: cereal beverages, coffee substitutes, beverages made from wheat products: beer, ale, beer without alcohol. Powders used in instant chocolate drinks.
  • Breads and cereals: white or brown bread, breadcrumbs, rolls. Donuts, sweet rolls, muffins, French toast, rusk, biscuits. Pre-made sponge cake mixes, breads and rolls.

Information for using wheat substitutes:

1 cup of wheat flour equals to:

  • 1 cup of rye meal.
  • 1 – 1¼ cups of rye flour.
  • 1 cup of potato flour.
  • 1⅓ cups of oat flour.
  • 1/2 cup of potato flour plus 1/2 cup of rye flour.
  • 5/8 cup of potato starch.
  • 5/8 cup of rice flour plus 1/3 cup of rye flour.






We can find rice in sake (Japanese liquor) as well as liquefied rice in health food shops.



Corn is an allergen difficult to eliminate since it is present in the form of starch in many elaborated products.

The following contain corn and therefore must be eliminated in the exclusion diet: Baking powder, caramel (corn syrup is often used), dextrin, maltodextrin, dextrose, fructose, glucono delta-lactone, invert sugar, invert syrup, malt, malt syrup, malt extract, mono and diglycerides, monosodium glutamate, sorbitol and starch.



Remember that you should avoid foods that have been fried in oil that has been previously used in cooking batter, cooked or have been handled in containers or utensils previously used in the manufacture of battered or coated dishes, and have not been washed and rinsed thoroughly.

It is also highly recommended that the allergic patient wears an identification bracelet or plate, with clear and conspicuous print, the type of food allergy and what specifically it is.

It is advisable to carry self-injectable epinephrine when eating out. The patient, family and carers should have the required training for its administration.
