Why is junk food harder to avoid for poor families, and who gets sicker?

Research question: How do grocery prices, limited store access in low-income neighborhoods, federal food assistance rules, and heavy marketing of packaged foods affect which people can realistically avoid processed foods, and how do the resulting diet-related health burdens fall unevenly across income, race, and regio

The records show that food budgets in poverty are insufficient to ensure optimum diets 4, and that geographic and sociodemographic disparities in ultra-processed food consumption contribute to diet-related health inequities in the US 5. Food insecurity falls disproportionately on US-born Hispanic, Black, and multi-racial individuals, partly because of living in food deserts, while new immigrants face the highest levels 1314. SNAP participants get a slightly higher share of their energy from ultra-processed foods (54.7%) than income-eligible non-participants (53.0%) 10, and EBT cards cannot buy hot or prepared foods 12. Six states began restricting soda and candy purchases in 2026 18, and a study found a 13% drop in soda purchases in the first two months, with the poorest households cutting 18.5% 27, though a federal court later vacated one waiver's approval 25; the newest fact, a USDA statement dated October 13, 2026, describes the waivers as restricting non-nutritious items 23. The facts do not include neighborhood-level grocery price or store-access data, or regional health-burden figures, so this answer covers the question only partially 13.
