Gluten-Free and Regular Foods: A Cost Comparison

Publication: Canadian Journal of Dietetic Practice and Research

Abstract

Purpose: The treatment of celiac disease is a strict gluten-free diet for life. This diet is assumed to be more expensive, although no studies confirm this assumption. In the current study, the prices of gluten-free foods and regular (gluten-containing) foods were compared to determine if and to what extent gluten-free products are more expensive.
Methods: Prices were compared for all food products labelled “gluten-free” and comparable gluten-containing food items in the same group available at two large-chain general grocery stores. The unit cost of each food, calculated as the price in dollars per 100 grams of each product, was calculated for purposes of comparison.
Results: All 56 gluten-free products were more expensive than regular products. The mean (± standard deviation) unit price for gluten-free products was $1.71 (± 0.93) compared with $0.61 (± 0.38) for regular products (p<0.0001). On average, gluten-free products were 242% more expensive than regular products (± 212; range, 5% to 1,000%).
Conclusions: All the commercially available products labelled gluten-free were significantly more expensive than comparable products. This information will be useful to dietitians who counsel individuals and families with celiac disease, and to celiac advocacy groups for lobbying the government about financial compensation.

Résumé

Objectif: Le traitement de la maladie coeliaque consiste à suivre toute sa vie un régime sans gluten. Bien qu’aucune étude ne l’ait confirmé, on suppose que cette alimentation coûte plus cher. Dans la présente étude, les prix des aliments sans gluten et ordinaires (avec gluten) ont été comparés pour déterminer si et dans quelle mesure les produits sans gluten coûtent plus cher.
Méthodes: On a comparé les prix de tous les produits alimentaires marqués «sans gluten» et ceux des produits comparables renfermant du gluten offerts dans deux magasins de grandes chaînes d’alimentation. À des fins de comparaison, le prix unitaire de chaque aliment a été calculé en dollars par 100 grammes.
Résultats: Les 56 produits sans gluten coûtaient plus cher que les produits ordinaires. Le prix unitaire moyen (± écart type) se chiffrait à 1,71 $ (± 0,93) comparativement à 0,61 $ (± 0,38) pour les produits ordinaires (p<0,0001). En moyenne, les produits sans gluten étaient 242% plus chers que les produits ordinaires (± 212, étendue: 5% à 1000%).
Conclusions: Tous les produits étiquetés «sans gluten» vendus sur le marché étaient significativement plus coûteux que les produits comparables. Cette information sera utile aux diététistes qui conseillent les personnes souffrant de la maladie coeliaque et leur famille, ainsi qu’aux groupes de pression de la maladie coeliaque dans leurs représentations auprès du gouvernement pour obtenir des compensations financières.
