Based on NIH | Is plain rice naturally gluten-free and safe for people with celiac disease to eat?

Yes plain, unseasoned rice is naturally gluten‑free and is generally considered safe for people with celiac disease. Rice (including white, brown, and wild rice) is listed among grains and starches that can be part of a gluten‑free diet. ^[1] Major clinical guidance also includes rice and wild rice as allowed grains for those with celiac disease. ^[2] Consumer‑facing medical references similarly list rice as a food you can eat on a gluten‑free diet. ^[3]

What “gluten‑free” means

Gluten is a protein found in wheat, barley, and rye, not in rice. When a product in the United States is labeled “gluten‑free,” it must contain less than 20 parts per million (ppm) of gluten, a threshold that helps protect people with celiac disease. ^[4] Because plain rice is naturally gluten‑free, it meets this definition as long as it hasn’t been contaminated by gluten during growing, processing, packaging, or cooking. ^[4]

Cross‑contact risks and how to avoid them

While rice itself does not contain gluten, cross‑contact (also called cross‑contamination) can occur when rice is processed, packaged, cooked, or served alongside gluten‑containing foods.

• Manufacturing lines: Naturally gluten‑free foods can pick up traces of gluten if produced on shared equipment with wheat, barley, or rye. ^[5] Not all packages warn about shared lines, so choosing brands that are certified or labeled gluten‑free can reduce risk. ^[4]
• At home and in restaurants: Cross‑contact can happen on shared surfaces or with shared utensils, like cutting boards, colanders, and toasters, so it’s helpful to keep separate tools for gluten‑free foods and clean kitchen equipment thoroughly. ^[6] Eating out can be challenging; asking how rice is cooked (e.g., separate pots, no wheat‑based broths or seasonings) can help you avoid accidental gluten exposure. ^[5]
• Seasonings and mixes: Plain rice is safe, but rice boxed with seasoning packets, sauces, or “pilaf” blends may contain gluten, so look for products specifically labeled gluten‑free or verify all ingredients. ^{[7] [8]}

Practical tips for choosing and cooking rice safely

• Buy plain rice or rice products labeled “gluten‑free” when possible to minimize cross‑contact risk. ^[4] This is especially useful for processed rice items like instant rice cups, frozen rice, or pre‑seasoned products. ^[7]
• Inspect ingredients on flavored or mixed rice products and avoid those with wheat, barley, rye, malt, or vague “natural flavors” unless confirmed gluten‑free. ^{[7] [8]}
• Use separate or well‑cleaned cookware and utensils, and consider dedicated items like a separate colander or rice cooker for gluten‑free use to reduce crumbs or residue. ^[6]
• Ask restaurants whether rice is cooked in plain water and separate equipment (not in stock thickened with flour or in soy sauce–based mixes unless the soy sauce is gluten‑free). ^[6]

How rice fits into a balanced gluten‑free diet

Rice can be a helpful staple, but variety supports better nutrition. Guidelines for celiac disease encourage a range of naturally gluten‑free grains and starches such as quinoa, buckwheat, corn, millet, sorghum, and tapioca alongside rice. ^[1] Many whole‑grain gluten‑free options add fiber and micronutrients to support digestive health and overall nutrition. ^[2]

A note on rice‑based products and arsenic

This doesn’t relate to gluten, but it’s useful context if rice is a major part of the diet. Studies have found that some rice and rice‑based products can contain inorganic arsenic; moderation and grain variety (e.g., mixing in quinoa, buckwheat, or millet) may help reduce exposure. ^[9] Diversifying grains is reasonable for both nutrition and risk reduction, especially for those relying heavily on rice‑based gluten‑free products. ^[9]

Bottom line

• Plain rice (white, brown, or wild) is naturally gluten‑free and is considered safe for people with celiac disease. ^{[1] [2] [3]}
• The main concern is cross‑contact, so choosing labeled gluten‑free products when possible, reading ingredient lists carefully, and preventing cross‑contact in the kitchen and at restaurants are sensible steps. ^{[4] [5] [6] [7]}
• Aim for variety by including other gluten‑free grains and starches to enhance nutrition and minimize reliance on any single grain. ^{[1] [2]}
