Dietary gluten avoidance in Canada: a cross-sectional study using survey data

Food Allergy Labeling and Disclosure Practices on Restaurants' Online Menus in Toronto, Canada

Restaurants have a responsibility to mitigate food-allergic reactions by nonverbally disclosing allergens on their menus and websites. In Canada, there are no laws requiring allergen labeling on non-pre-packaged food, leaving it up to restaurant managers to decide how to accommodate allergic customers. A cross-sectional study was conducted to assess allergen disclosure and labeling on online menus in Toronto, Canada. A random sample of 1,000 nonchain restaurants was sourced from DineSafe, Toronto's food inspection system. The online menus of each restaurant were accessed and assessed using a checklist in 2023-2024 to determine the presence of allergen menus, statements, or symbols. Mixed-effect logistic regression models were developed to assess the relationship between restaurant characteristics (cuisine type, Google review rating, cost indicator, and number of locations) and two outcomes: (1) presence of at least one allergen symbol on the menu, and (2) presence of an allergen statement on the menu. Only 16% (n = 159) of restaurants included allergen statements, and only 10% (n = 100) used allergen symbols. Regression models predicted that vegan and vegetarian restaurants were the most likely cuisine type to have at least one allergen symbol on their menu (19%, 95% CI: 13-24%), and Southeast Asian restaurants were the most likely to have an allergen statement (28%, 95% CI: 20-36%). Additionally, higher restaurant costs and multiple locations were linked to more allergen disclosures. This study highlights the need for improved allergen labeling in nonchain restaurants. Policies requiring allergen disclosures can improve menu transparency and encourage proactive customer-waiter interactions, preventing allergic reactions in restaurants.

Gluten-Free Product Recalls and Their Impact on Consumer Trust

The range of gluten-free food products available to consumers is steadily expanding. In recent years, recalls of food products have highlighted the importance of accurate labeling of food products for the presence of wheat, other gluten-containing cereals, or gluten itself as refined ingredient. The purpose of this study was to gain more insights into recent food recalls related to undeclared gluten/wheat contamination and consumer experiences with these recalls. Recalls of products triggered by gluten contamination are relatively scarce and are not often triggered by a consumer complaint. The impact of these recalls on consumer trust was evaluated through an online survey that was distributed among supporters of Celiac Canada (CCA) and covered (i) strategies to adhere to a gluten-free diet, (ii) experiences with gluten-free recalls and their impact on consumer trust, and (iii) demographic information. Consumer concern regarding gluten-free product recalls is significant, but the concern regarding recalls is not heightened after experiencing a recall. Companies pursuing transparency in the process, identification of the source of contamination, and mitigation strategies going forward are likely to retain consumer trust in their product and brand. Based on the survey results, further efforts focusing on consumer education regarding interpreting nutrient labels, identifying sources of information on product recalls, and understanding procedures to follow upon suspected gluten contamination of a gluten-free product are recommended.

Identifiable Dietary Patterns of Pregnant Women: A Canadian Sample

Purpose: To estimate the percentage of a sample of pregnant women in Canada following a vegetarian, vegan, low-carbohydrate, gluten-free, Mediterranean, or well-balanced diet, before and during pregnancy and to explore if pregnant women received and were satisfied with nutrition information received from health care providers (HCPs).Methods: Participants were conveniently sampled through Facebook and Twitter. An online survey collected data on sociodemographic characteristics, maternal diet, and whether women received and were satisfied with nutrition information from their HCPs. The McNemar test assessed changes in the proportion of diets followed before and during pregnancy.Results: Of 226 women, most followed a well-balanced diet before (76.9%) and during (72.9%) pregnancy (p = 0.26). Vegetarian, gluten-free, vegan, and low-carbohydrate diets were the least followed diets before and during pregnancy (vegetarian: 7.6% vs 5.3%; gluten-free: 4.9% vs 4.0%; vegan: 2.7% vs 2.2%; low-carbohydrate:4.0% vs 0.4%). Overall, the number of women following restrictive diets before pregnancy was significantly reduced throughout pregnancy (19.1% vs 12.0%, p < 0.001). Only 52.0% of women received nutrition information from their primary HCP, and 35.6% were satisfied with the nutrition information received.Conclusions: Most women followed a well-balanced diet before and during pregnancy and approximately one-third were satisfied with the information received from HCPs.
