HHS Secretary Robert F. Kennedy Jr. often talks about reforming prison food in the same breath as school food, a genuinely unusual thing for a top health official to say. At the same time, the Federal Bureau of Prisons has quietly put out requests for information about outsourcing food service to the same private companies that serve colleges, elementary schools, and military bases. Are these two positions aligned? What would it take to actually improve food served in prisons? Why does it matter? We dive into all of it with two of the country’s top experts in prison food. Daniel Rosen co-founded the Carceral Nutrition Project after six years incarcerated in Virginia and Washington, D.C. Leslie Soble is a folklorist and ethnographer whose research became Eating Behind Bars: Ending the Hidden Punishment of Food in Prison, which just won a James Beard Award (Soble is also a founding board member of the Carceral Nutrition Project). Together, Rosen and Soble lay out what's actually on the tray, who's profiting from it, and why the whole "you did the crime, you do the time" doesn't actually make sense when you consider how to feed incarcerated people. Highlights: Prison and jail systems spend $1.50 to $2 a day feeding someone, a fraction of what the federal school lunch reimbursement coversThe wild imbalance between healthcare and food spending in correctional facilitiesHow privatization works (about a third of prison food service is outsourced)The science connecting better nutrition to lower violence in correctional facilitiesWhat the Trump administration is/isn’t doing to reform prison foodWhat national standards for prison food could actually look like Where to find Daniel Rosen and Leslie Soble: Carceral Nutrition Project Eating Behind Bars: Ending the Hidden Punishment of Food in Prison Additional Reading: "Private Food, Public Harm" — the CSPI/Carceral Nutrition Project report on privatized prison food service Gesch et al.
