In supermarkets, the gluten-free products section is becoming easier to find. Among pasta packages, sliced bread, cookies, flours, pizza bases, and muffins, one color often dominates: the intense yellow of Schär packaging. The image contrasts with the reality of just a few decades ago, when following a gluten-free diet meant navigating pharmacies, health food stores, specialty shops, and homemade recipes based on rice, corn, or potato. Before these products occupied entire shelves, celiac people had to fend for themselves in a market with very little supply.
