Hidden gluten

Gluten is a protein found in some grains, notably wheat, barley, and rye. The symptoms of celiac disease (such as diarrhea, weight loss, and abdominal bloating) may or may not occur after eating foods that contain gluten. But if you have celiac disease, eating gluten triggers an immune response that is not normal and can lead to damage of your small intestine. This damage can occur even when you do not notice symptoms.

Some foods and food products may contain gluten even when it is not specifically listed as an ingredient. The following foods and food products may have hidden gluten:

Milk products

  • Ice cream and dairy products
  • Cheese spreads
  • Yogurt with fruit

Processed foods

  • Hot chocolate mixes or cocoa, chocolates, and candy bars
  • Bouillon cubes, soup mixes, and canned soups
  • Processed meats and poultry, such as hot dogs and sausages

Other products

  • Nondairy creamer, luncheon meats, salad dressings, mustard, ketchup, tomato sauce, and peanut butter
  • Communion wafers used in religious services
  • Hydrolyzed vegetable protein, which is a filler product used in many prepared or processed foods

If you have celiac disease, it is important for you to learn about sources of hidden gluten. Because you may not always have symptoms, you cannot judge whether a food is safe by how you feel after eating it.

Some medications contain gluten. Ask your health professional whether the medications you take contain gluten. You can also ask your pharmacist when buying nonprescription medications, but often you must contact the manufacturer of the medication to find this information.
