Food insecurity refers to a situation that exists when people lack secure
access to sufficient amounts of safe and nutritious food for normal growth
and development and an active and healthy life. It may be caused by
the unavailability of food, insufficient purchasing power, inappropriate
distribution, or inadequate use of food at the household level. Food
insecurity, poor conditions of health and sanitation, and inappropriate
care and feeding practices are the major causes of poor nutritional status.
