Abstract

Gluten proteins in cereal grains are often considered unsafe for health. Indeed, the dissemination of misinformation through various sources has led to a widespread misconception that the consumption of gluten by healthy individuals results in adverse health consequences and contributes to obesity. In recent years, many health-conscious consumers have started reducing or avoiding gluten consumption without a medical recommendation. Consequently, the adoption of gluten-free diets has expanded significantly. This study compared 39 gluten-free products and their gluten-containing counterparts for energy, sugar, dietary fiber content, and price. We found that, on average, gluten-free products available to United States consumers contained significantly less protein and more sugar and calories. Furthermore, on average, gluten-free products are more expensive than gluten-containing products. Our finding may serve as a guide for dietitians, nutritionists, and legislators in introducing a gluten-free prescription list for individuals with celiac disease, wheat allergy, and non-celiac wheat sensitivity.
