Although information regarding food insecurity in this population is limited, the available data suggest that food insecurity is a major problem on First Nations reserves. For example, in Kugaaruk, Nunavut in 2001, 83% of households experienced food insecurity and in Fort Severn Ontario it was 70 %. There are several key issues with respect to food insecurity in this population. Firstly, market food is expensive, and often unavailable, and of poorer quality and nutritional value. There are also barriers to the consumption of food harvested from the local environment including lack of equipment, changing tastes, loss of skills and preparation expenses. Contamination of the food supply and climate change are two other important considerations.
