"Grain-free" refers to a dietary approach that eliminates all grains, such as wheat, rice, corn, and oats. This type of diet is often adopted for various reasons, including food allergies, sensitivities, or a desire to reduce carbohydrate intake. People following a grain-free diet typically focus on consuming fruits, vegetables, nuts, seeds, and animal proteins. Many grain-free products are available, including snacks and baked goods made from alternative flours like almond or coconut flour. This trend has gained popularity among those interested in paleo or keto diets, which emphasize whole foods and limit processed ingredients.
