It helps food maintain its shape by providing elasticity and moisture. It also allows bread to rise and provides a chewy texture (1).
Although gluten is safe for most people, those with conditions like celiac disease or gluten sensitivity should avoid it to prevent adverse health effects (2).
Many foods are made with gluten-containing ingredients, so it’s important that those who are unable to consume it check ingredient labels closely.
Here is a list of 54 gluten-free foods. 1–11. Whole grains
A select few whole grains contain gluten, while the rest are naturally gluten-free.
It’s important to check food labels when purchasing whole grains. Even gluten-free whole grains can be contaminated with gluten, especially if they are processed in the same facility as gluten-containing foods (3).
For example, oats are often processed in facilities that also process wheat, which can lead to cross-contamination. For this reason, you should confirm that the oats you purchase are certified gluten-free (4).
Gluten-free whole grains
- brown rice
- wild rice
- oats (make sure they’re labelled as gluten-free as they may be contaminated with gluten during processing.)
Grains to avoid
- wheat, all varieties (whole wheat, wheat berries, graham, bulgur, farro, farina, durum, kamut, bromated flour, spelt, etc.)
These gluten-containing grains are often used to make products like bread, crackers, pasta, cereals, baked goods, and snack foods.12–26. Fruits and vegetables
All fresh fruits and vegetables are naturally gluten-free. However, some processed fruits and vegetables may contain gluten, which is sometimes added for flavoring or as a thickener (3).
Gluten-containing ingredients that may be added to processed fruits and vegetables include hydrolyzed wheat protein, modified food starch, malt, and maltodextrin.

Ingredients to look out for

- malt-based ingredients, including malt vinegar, malt extract, and malt syrup
- gluten stabilizer
- soy or teriyaki sauce
- wheat-based ingredients, such as wheat protein and wheat flour
- emulsifiers (will be specified on the label)
If you are unsure if a product contains gluten, it’s a good idea to contact the manufacturer to double-check.Conditions that can be helped by a gluten-free diet
A gluten-free diet is typically recommended for those with celiac disease, a condition that triggers an immune response when foods containing gluten are consumed (6).
Those with non-celiac gluten sensitivity should also avoid gluten, as it can contribute to symptoms like bloating, stomach pain, and diarrhea (7).
Although more research is needed, several studies also suggest that a gluten-free diet could be beneficial for those with irritable bowel syndrome, a chronic disorder characterized by digestive issues like stomach pain, gas, diarrhea, and constipation (8, 9, 10).Risks of a gluten-free diet
Gluten is found naturally in many nutritious foods, including whole grains like wheat, barley, and rye.
Meanwhile, some processed, gluten-free food products are not enriched with vitamins and minerals. As such, following a gluten-free diet that lacks diversity could increase the risk of deficiencies in folate, riboflavin, niacin, and iron (11).
Therefore, it’s essential to ensure that you’re getting these important nutrients from other sources as part of a healthy, gluten-free diet to help reduce the risk of side effects.The bottom line
If you avoid gluten, there are plenty of foods you can choose from to ensure a well-balanced diet.
Many healthy foods are naturally gluten-free, including fruits, vegetables, legumes, certain whole grains, dairy products, and oils, as well as fresh meat, fish, and poultry.
Wheat, rye, and barley are the major foods that need to be avoided while following a gluten-free diet. Gluten is also commonly added to processed foods, such as canned and boxed items.
Furthermore, some grains, such as oats, may be cross-contaminated with gluten, depending on where they were processed.
Success with a gluten-free diet comes down to double-checking ingredient labels, as gluten is often added to foods that you wouldn’t expect. Foods that contain gluten will be labeled as such.
Nevertheless, if you focus on eating mostly fresh, whole, gluten-free foods and a minimal amount of processed foods, you will have no problem following a gluten-free diet.
