A strict, lifelong gluten-free diet is the only treatment for celiac disease. The question of what a gluten-free person eats can seem daunting, but an abundance of naturally gluten-free foods exists to create a diverse and satisfying diet.

Quick Summary

A gluten-free diet includes naturally gluten-free foods like fruits, vegetables, unprocessed meats, and legumes. It also uses alternative grains and flours, while avoiding wheat, barley, and rye. Careful label reading and preventing cross-contamination are essential for success and for preventing potential nutritional deficiencies.

Key Points

Focus on Whole Foods: Naturally gluten-free foods like fruits, vegetables, meats, and legumes should form the core of a gluten-free diet.
Embrace Alternative Grains: Replace wheat-based products with gluten-free grains such as quinoa, brown rice, certified gluten-free oats, and buckwheat.
Become a Label-Reading Expert: Hidden gluten can be found in processed foods, sauces, and flavorings, so careful label reading is critical.
Prevent Cross-Contamination: Use separate kitchen utensils and food preparation areas to avoid trace gluten for those with celiac disease.
Address Nutritional Needs: Be mindful of potential deficiencies in fiber, B vitamins, and other nutrients, which can be mitigated by choosing fortified products and a diverse diet.
Explore Gluten-Free Flours: Use almond, coconut, sorghum, or chickpea flour as substitutes for wheat flour in baking, each offering different properties and benefits.

Navigating Naturally Gluten-Free Foods

For individuals following a gluten-free diet, nutritious, naturally gluten-free foods are the foundation for delicious meals. The focus shifts from processed foods containing gluten to whole, unprocessed ingredients.

Core Food Groups for a Gluten-Free Diet

Fruits and Vegetables: All fresh fruits and vegetables are naturally gluten-free, providing essential vitamins, minerals, and fiber. Enjoy everything from leafy greens like spinach and kale to starchy vegetables like potatoes and squash. Be mindful of canned or frozen varieties with added sauces or flavorings that may contain gluten.
Proteins: Unprocessed meats, poultry, fish, and legumes are excellent protein sources. Fresh beef, pork, chicken, turkey, and fish are all safe choices. Look for plain tofu, beans, and lentils, but always check pre-seasoned versions for hidden gluten. Nuts and seeds are also naturally gluten-free and can be incorporated into snacks or meals.
Dairy: Most plain dairy products, including milk, plain yogurt, and cheese, are gluten-free. Flavored products, such as certain yogurts or processed cheeses, may have gluten-containing additives, so always read the label.
Fats and Oils: Most healthy fats and oils, such as olive oil, coconut oil, and avocados, are naturally gluten-free. Nuts and seeds also provide healthy fats.

The World of Gluten-Free Grains and Alternatives

While wheat, barley, and rye are off-limits, a variety of grains and flours offer safe and tasty substitutes. These can be used to make breads, pastas, and baked goods.

Quinoa: A complete protein, quinoa can be used as a rice substitute or as a base for salads and bowls.
Rice: Both brown and white rice are naturally gluten-free, with brown rice offering more fiber. Look for rice flour for baking.
Buckwheat: Despite its name, buckwheat is not a type of wheat and is a great source of fiber and protein. It can be used for pancakes and noodles.
Oats: Pure, uncontaminated oats are gluten-free, but they are often cross-contaminated during processing. Always choose products specifically labeled as "certified gluten-free oats".
Corn: Cornmeal, corn flour, and corn tortillas are gluten-free, though some packaged products might have added wheat flour.
Teff and Millet: These ancient grains are naturally gluten-free and offer a unique texture and flavor to baked goods.

Uncovering Hidden Gluten and Preventing Cross-Contamination

Gluten can hide in unexpected places, especially in processed and pre-packaged foods. For those with celiac disease, even trace amounts can cause a reaction. Becoming an expert label-reader is essential.

Check Sauces and Condiments: Many common items like soy sauce, gravies, salad dressings, and marinades contain wheat or malt. Look for gluten-free versions or naturally gluten-free alternatives like tamari or coconut aminos.
Be Aware of Additives: Check food additives such as modified food starch, maltodextrin, and flavorings, which can sometimes be derived from wheat.
Prevent Cross-Contamination: In shared kitchens, take steps to avoid cross-contact between gluten-free and gluten-containing foods. Use separate cutting boards, toasters, and utensils, or clean them thoroughly before use. Dedicated areas for gluten-free food prep are ideal.

Comparison of Gluten-Free Flours

When it comes to baking, different gluten-free flours have unique properties. Here is a comparison to help you choose the right one for your needs.

Nutritional Considerations for a Gluten-Free Diet

Simply replacing gluten-containing foods with gluten-free processed products can lead to potential nutritional deficiencies. Many gluten-free alternatives are lower in fiber, B vitamins (thiamin, niacin, riboflavin), iron, folate, and other minerals compared to fortified wheat products. It is crucial to focus on a balanced, whole-food-based diet to counteract this.

Tips for a Nutritionally Complete Diet

Increase Naturally Rich Foods: Incorporate plenty of fruits, vegetables, legumes, nuts, and seeds to boost fiber, vitamin, and mineral intake.
Choose Fortified GF Products: Opt for gluten-free cereals, breads, and pastas that are fortified with essential nutrients.
Select Whole Grains: Use naturally gluten-free whole grains like quinoa, brown rice, and certified gluten-free oats to increase fiber.
Consult a Professional: A registered dietitian can help create a balanced meal plan and identify any potential deficiencies that may require supplementation.
