Are Grits Gluten-Free?

From The New Day Notebook · Facts last checked October 21, 2026 · General information, not medical advice

Yes, grits are usually gluten-free. The essential ingredient in grits is ground corn, and corn is a naturally gluten-free grain. This simple fact makes plain grits a suitable food for many people who avoid gluten.

The main consideration is how the corn is harvested, milled, and packaged. Cross-contact with wheat, barley, or rye can happen during these steps, which could add gluten to the final product. For this reason, it is important to check the packaging and be mindful of how grits are prepared.

Grits and gluten at a glance

Why grits are usually gluten-free

Grits are a simple food made by grinding dried corn kernels, typically into a coarse meal. Since corn in its natural form does not contain any gluten proteins, the grits made from it are also naturally gluten-free. Whether yellow or white, stone-ground or quick-cooking, the base ingredient remains the same.

This makes plain, unadulterated grits a reliable and versatile staple. They can be served as a creamy breakfast porridge, a savory side dish, or the foundation for main courses. Because they are based on a gluten-free grain, they provide a good alternative to wheat-based cereals like cream of wheat or farina.

Where gluten can be a concern

The primary risk for gluten in grits comes from cross-contact. If corn is processed in a facility that also handles wheat, rye, or barley, there is a possibility that gluten particles could mix into the grits. This can occur during milling, processing, or packaging if equipment is shared between gluten-containing and gluten-free grains. Bulk bins at grocery stores are another potential source of cross-contact.

Additionally, some grits products, particularly flavored or instant varieties, may contain added ingredients that include gluten. Seasoning packets, sauces, or broths can sometimes use wheat flour or other gluten-based thickeners and flavorings. It is always necessary to read the full ingredient list for these types of products.

Shopping, cooking, and eating out

When shopping for grits, the most straightforward approach is to look for packages that are explicitly labeled gluten-free. In the United States, a gluten-free label means the food must contain less than 20 parts per million (ppm) of gluten, according to the Food and Drug Administration’s 2013 rule.

At home, prepare grits in a clean pot with dedicated utensils to avoid cross-contact from other foods in your kitchen. When dining out, a popular dish like shrimp and grits can be a source of hidden gluten. The gravy or sauce is often thickened with wheat flour. Always ask the restaurant staff about their ingredients and preparation methods to ensure the dish is prepared safely for your needs. Mentioning the possibility of flour in the sauce can help guide the conversation.

When to loop in your doctor or dietitian

People with celiac disease require a strict, lifelong gluten-free diet for their health and should always be vigilant about ingredients and preparation. If you are considering a gluten-free diet for medical reasons, talk to your doctor or a registered dietitian. Do not begin avoiding gluten until after you have completed medical testing for celiac disease, as the tests require gluten to be present in your system for an accurate result.

• If you think gluten is making you unwell, ask about celiac disease testing before cutting gluten out: testing needs gluten in the diet
• If you have celiac disease and still have symptoms on a gluten-free diet
• If you are unsure whether oats, wheat starch or a specific ingredient suits you
• For help planning a gluten-free diet that still meets your nutrition needs
