Did you know that people who are incarcerated typically receive poor quality food that contributes to poor mental and physical health? Join Food Sleuth Radio host and Registered Dietitian, Melinda Hemmelgarn for her conversation with Jessi Silverman, MPH, RD, Deputy Director in the Programs Department at the Center for Science in the Public Interest.
