The Menu Served in Canadian Penitentiaries: A Nutritional Analysis.

The food served in Canadian penitentiaries was scrutinized following food service reform where Correctional Service Canada (CSC) created a standardized menu to feed incarcerated male individuals. Food in prison is a complex issue because penitentiaries are responsible for providing adequate nutrition to the prison population, who are vulnerable to poor health outcomes but are often seen as undeserving. This study aimed to analyse the national menu served in Canadian penitentiaries, in order to compare them with Dietary Reference Intakes (DRIs) for male adults and the internal nutritional assessment reported by CSC. The goal was to verify if the menu served was adequate and to validate CSC's nutritional assessment. The diet analysis software NutrificR was used to analyse the 4-week cycle menu. Both analyses were within range for DRIs for most nutrients. However, some nutrients were not within target. The sodium content (3404.2 mg) was higher than the Tolerable Upper Intake Levels (UL) of 2300 mg, the ω-6 (linolenic acid) content (10.8 g) was below the AI of 14 g, and the vitamin D content (16.2 μg) was below the target of 20 μg for individuals older than 70 years. When these outliers were analysed in-depth, the menu offering was consistent with the eating habits of non-incarcerated individuals. Based on this nutritional analysis and interpretation of the results in light of the complex nature of prison food, this study concludes that CSC meets its obligation to provide a nutritionally adequate menu offering to the general population during incarceration.
