The Study
Ultra-processed foods and non-alcoholic fatty liver disease: an updated systematic review and dose–response meta-analysis
This study looks at lots of other studies that watched people eat and checked if they got fatty liver disease. It found that people who eat more ultra-processed foods, like chips and soda, are more likely to have fatty liver. But it can't say for sure that the food caused the disease — it just shows they go together.
