This article examines the relationship between obesity and the affordability of food. While some argue that the availability of certain types of foods has a causal effect on obesity, there is little definitive data supporting this claim.
The author presented this article at the conference "Food Systems and Public Health: Linkages to Achieve Healthier Diets and Healthier Communities." Sturm utilizes the framework of multifunctionality to examine the complex relationship between food consumption and obesity. Multifunctionality examines the linkage between commodity and non-commodity output production in food systems.
The relationship between obesity and other food policy issues is complex and at times weak. Portraying obesity as a result of poverty and food insecurity does not accurately reflect the evidence behind a complicated problem.
