Food Insecurity, Cardiometabolic Risk and Cardiovascular Disease: A Narrative Review and Call for Action

Food insecurity and insufficient access to affordable nutrition have been associated with increased risk for the development of multiple chronic medical conditions, including cardiovascular disease. In this narrative review, we explore the association between food insecurity and the development of chronic medical conditions that confer increased cardiometabolic risk, cardiovascular disease, and mortality. We also identify the various barriers leading to food insecurity and lack of food literacy, with an emphasis on patients with high blood pressure, diabetes mellitus, stroke, congestive heart failure, and coronary heart disease. We discuss recent developments in legislation and public policies and programs designed to expand our understanding and reduce food insecurity at the local, regional, national, and international levels, and identify opportunities for future research and innovation.
