Due to the complex nature of the food system, this is not as straightforward as simply increasing the production of healthy foods and decreasing the production of unhealthy foods. Little is known about whether the US food system can produce enough food, given finite agricultural resources, to support shifts toward healthier eating patterns.<h4>Objective</h4>The aim of this study was to model the capacity of the US food system to accommodate a shift toward a healthier diet by 2030.<h4>Methods</h4>A biophysical simulation model estimated the proportion of the US population that could be fed a given diet based on food system constraints, currently and projected to 2030.
