The Hamilton Project released this report that looks at the problem of food insecurity in the the United States and the important role that SNAP plays in reducing food insecurity.
One in seven households was food insecure in 2014—meaning that at some time during the year they had difficulty providing enough food for all of their members due to a lack of resources. 15 million children live in food-insecure households. Even more troubling, in 2014 just over 1 in 20 households—almost 7 million households—suffered one or more periods during which food intake of household members was reduced and normal eating patterns were disrupted because the household lacked money and other resources for food.
To be sure, the phenomenon of food insecurity in the United States is not equivalent to the severe malnutrition observed in some developing countries. Nonetheless, it has far-reaching impacts on the health and well-being of an unacceptably large number of Americans adults and children. The common-sense notion that lack of access to food is harmful has been established by rigorous research. Children living in food-insecure households tend to have a lower health-related quality of life, higher rates of asthma, less nutritious diets, and behavioral problems that affect school performance.
