That creamy Reese’s peanut butter cup dissolving on your tongue. The next crunchy Dorito you’re reaching for before you’ve swallowed the last one. The first sip of an ice-cold Coke, with a mix of syrup and carbonation; it hits like relief.

Your brain’s reward center is supposed to keep you alive, but a major new study from the University of Michigan, Harvard, and Duke says the food industry learned how to use it against you — engineering products with the same science as cigarettes.

The playbook is this: optimize the craving, accelerate the reward, and make it nearly impossible to stop.

Ultraprocessed foods now make up roughly 60% of what Americans eat. San Francisco has sued 10 major food manufacturers over the harm.

Health Secretary Robert F. Kennedy Jr. has said these foods are poisoning Americans, but he has stopped short of regulating them.

In Detroit, 69% of households face food insecurity and researchers describe the city as a food swamp, where drive-throughs, party stores and gas-station snack aisles vastly outnumber places to buy fresh produce.

Detroit’s numbers make the question sharper: What happens when engineered food is all that’s there?

Ashley Gearhardt, clinical psychologist, addiction scientist at the University of Michigan, creator of the Yale Food Addiction Scale and lead author of the study, joined Robyn Vincent on The Metro to discuss this and more.

Part of the affordability crisis hitting American families is happening on our plates.

One local wholesale distributor says multiple factors are driving food costs up: President Trump’s tariffs, labor shortages and heightened immigration enforcement, and problems in the trucking industry. And all of that hits Detroit harder than most places. Many Detroit families struggle with food insecurity, and Congress just gutted the federal safety net that millions of families depend on.

Still, whether prices go up because of a tariff or a drought or a trucker shortage — if you don’t control any part of the system, you just absorb the hit. You are at the end of a chain somebody else built and no food pantry, no matter how well-run, changes that.

Natosha Tallman says the answer is not more charity — it’s infrastructure: commercial kitchens, cold storage, distribution, ownership. A system where Detroiters grow food, process it, sell it, and keep the money. 

Tallman and her team at the Northend Christian Community Development Corporation, which runs the Oakland Avenue Urban Farm, are trying to build that infrastructure. She joined Robyn Vincent on The Metro to discuss what it takes to move from a system focused on food charity to one of food sovereignty.
