Observational Study: Ultra-Processed Foods and Fat Buildup in Thigh Muscles
In MRI scans of 615 adults at risk for knee osteoarthritis, eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles. The association remained even after researchers accounted for calorie intake, physical activity, and other factors.
What the Research Says
Hypothesis: The analysis is based on MRI scans of 615 adults at risk for osteoarthritis; fatty changes in these muscles may weaken support around the knee and potentially increase osteoarthritis risk.
