For some, it's a choice, for others, a necessity. But regardless of the reasons, gluten-free has become a huge food trend in the last few years. Gluten is a plant-based protein found in foods like bread, pasta and baked goods. Some nutritionists claim a gluten-free diet has the potential to relieve everything from digestive issues, joint pain, fatigue, weight gain and arthritis. But cutting out gluten doesn't have to mean cutting out the foods you enjoy day-to-day. Several grains and starch sources are considered acceptable substitutes, like corn, potatoes, rice, millet, quinoa and yams. Here, find gluten-free versions of the dishes you love, from Pad Thai and muffins to cookies and cupcakes.
