The potential for healthier consumer food substitutions is an important factor in the study of food environments, dietary choices, and population nutrition promotion. The burden of diet-related non-communicable diseases is unevenly distributed across Canada and variation in the food environment sub-nationally may be an important explanation. We used population-based 24 h dietary recall data from the 2015 Canadian Community Health Survey-Nutrition for Canadian adults ( = 13 919) to examine dietary intakes of two food group pairings (whole grains/refined grains and legumes/red meats) where consumer substitutions have been recognized to be of importance in promoting healthy and sustainable population diet.

It is not yet well understood how pricing can be used to encourage healthier substitute purchases. The aim of the study was to assess the effect of a retailer-led relative pricing intervention on weekly purchases of targeted snack foods and beverages.

Further, this study tested the hypothesis that a product-matched digital NNFB (dNNFB) correlates with existing market basket measures and quantified any differences in costs. This was an observational cross-sectional study using web scraped food price data collected in November 2021.

Robust measurement is needed to determine the effect of COVID-19 on dietary intakes and consumer purchasing, given the widespread changes to consumer food environments and economic precarity. The research objectives are as follows: (1) describe dietary intakes of foods, beverages and nutrients of concern during the COVID-19 pandemic; (2) quantify change in diet during COVID-19 as compared with prepandemic, previously captured in the provincial samples of the population-representative 2015 Canadian Community Health Survey-Nutrition and (3) examine how household purchasing practices predict dietary intakes during COVID-19.

In an effort to propel system-wide change to support healthy eating, Nova Scotia Health developed and implemented a healthy eating policy as a benchmark to create a food environment supportive of health. This article describes the healthy eating policy and its role as a benchmark in the quality improvement process.

Design And Setting: Data were collected in a cafeteria. Meals, selected by participants (=30), were documented using the AV method: participants video-recorded their tray while audio-recording a description of their selected meal, after which the research team digitally weighed each food item and created an itemized diary record of the food.
