The Hunger and Obesity Paradox
A number of researchers have explored the paradoxical link between lack of regular access to adequate food (food insecurity) and increased risk of obesity. (1,2) At present, however, there is no definitive answer to the question of whether experiencing food insecurity leads to obesity.
Some studies in the U.S. have found that federal food assistance programs intended to improve diets among food insecure families, such as the Supplemental Nutrition Assistance Program (or SNAP, the program formerly known as food stamps), may actually be linked with increased risk of overweight. The findings have not been consistent, however, and may vary by program and by other aspects of the food environment, such as food prices. (3-5) More research is needed, especially pilot studies that explore different ways to improve the quality of foods purchased with food stamps. The SNAP to Health website, from the Center for the Study of the Presidency and Congress, offers a good exploration of the issues around SNAP, nutrition, and obesity.
