An exploration of reported food intake among inmates who gained body weight during incarceration in Canadian federal penitentiaries.

Food intake during incarceration is a modifiable risk factor that could be the target of weight management interventions with inmates. Our findings suggest that inmates who gained the most weight also reported having low intake of foods deemed healthy (vegetables, fruit, cereal, dairy and legumes) from food services and from the commissary store (or "canteen") purchases.
