The document discusses the relationship between overnutrition and poverty, and the impact on public health. It finds that poverty limits access to nutritious foods and leads to consumption of cheap, unhealthy options. This relationship increases the risk of obesity, type 2 diabetes, heart disease, and stroke in low-income communities. Treating diseases from overnutrition poses a large economic burden on healthcare costs. Addressing overnutrition as a public health issue could help lower rates of chronic diseases in low-income areas and reduce health expenditures.
