Food, diet and nutrition in food insecure populations

Poverty constrains food selection, acquisition, and consumption. When shopping for food, individuals living in severely food-insecure households are most likely to make food purchasing decisions solely based on price, foregoing preference, quality and health considerations. Among the most vulnerable groups like homeless youth, very high rates of severe food insecurity accompany risky and dangerous food acquisition strategies (e.g. theft and trading sex for food).

In Canada, like in other high-income countries, households with higher incomes and/or higher levels of education consume more nutritious foods, while individuals living in lower-income or food insecure households consume lower quality, less nutritious diets. But, from a public health perspective, it is important to know the degree to which these eating patterns impact nutritional health. In 2008, the first national study in Canada to examine the relationship between household food insecurity and nutrient intake demonstrated that household food insecurity is associated with diets that are inadequate to support health in adults and adolescents. It has been suggested that inequalities in nutrition may play a role in income-related health disparities whereby low-income Canadians suffer increased rates of disease and shorter life expectancy.  

While research reveals some differences in food intake patterns among children living in food-insecure households, these do not appear to be related to higher rates of nutrient inadequacy.
