The Study
Association of ultra-processed foods consumption with increased liver steatosis in U.S. adults
This study is like taking a snapshot of people’s diets and liver health at one point in time. It can show that people who eat more ultra-processed foods tend to have more fat in their liver, but it can’t prove that the foods caused the fat. It’s possible that other factors, like overall lifestyle, play a role.
