What is Food Insecurity?
The U.S. Department of Agriculture (USDA) defines food insecurity as a lack of consistent access to enough food for an active, healthy life. It is important to know that though hunger and food insecurity are closely related, they are distinct concepts. Hunger refers to a personal, physical sensation of discomfort, while food insecurity refers to a lack of available financial resources for food at the household level.
Extensive research reveals food insecurity is a complex problem. Many people do not have the resources to meet their basic needs, challenges which increase a family’s risk of food insecurity. Though food insecurity is closely related to poverty, not all people living below the poverty line experience food insecurity and people living above the poverty line can experience food insecurity.
Food insecurity does not exist in isolation, as low-income families are affected by multiple, overlapping issues like lack of affordable housing, social isolation, chronic or acute health problems, high medical costs, and low wages. Taken together, these issues are important social determinants of health, defined as the “conditions in the environments in which people are born, live, learn, work, play, worship and age that affect a wide range of health, functioning and quality-of-life outcomes and risks.” Effective responses to food insecurity must address the overlapping challenges posed by the social determinants of health. Hunger + Health explores the impact of food insecurity as a social determinant of health and its effect on individual and population health outcomes.
