The duality of food production and consumption in the United States: Science, health, and practices

Abstract

The United States food system is a paradox of abundance and inequity, characterized by high agricultural productivity and innovation on one hand, and growing public health, environmental, and socio-economic challenges on the other. This chapter examines the duality of food production and consumption in the U.S., tracing how scientific advances, industrial-scale farming, and market dynamics have shaped food availability, quality, and accessibility. While innovations such as biofortification, precision agriculture, and controlled environment farming have improved yield and efficiency, they often come at the cost of nutritional value, environmental sustainability, and equity. The chapter highlights how marginalized communities face disproportionate exposure to food insecurity, ultra-processed diets, and environmental health risks, while farmers themselves contend with economic pressures, mental health challenges, and shrinking autonomy. Community-based food systems, including Community Supported Agriculture (CSA), urban agriculture, food co-ops, and grassroots food sovereignty movements, offer promising models for a healthier, more equitable future. Policy recommendations emphasize the need for holistic, cross-sectoral approaches that realign agricultural priorities with public health goals, support farmer livelihoods, and ensure access to nutritious food for all. By addressing the intersections of health, sustainability, and justice, this chapter contributes to a broader reimagining of food systems that center people, planet, and shared prosperity.
