Ultra-processed foods may not only affect our bodies, but our brains too.

New research suggests links between ultra-processed foods—such as chips, many cereals and most packaged snacks at the grocery store—and changes in the way we learn, remember and feel. These foods can act like addictive substances, researchers say, and some scientists are proposing a new mental-health condition called “ultra-processed food use disorder.” Diets filled with such foods may raise the risk of mental health and sleep problems.
