Ultra-processed foods linked to hidden muscle fat that may threaten your knees
Source: ScienceDaily
What the research found
Eating more ultra-processed foods was linked to greater fat buildup inside thigh muscles, according to MRI scans of 615 adults at risk for knee osteoarthritis. Surprisingly, the association remained even after researchers accounted for calorie intake, physical activity, and other factors. Fatty changes in these muscles may weaken support around the knee and potentially increase osteoarthritis risk.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
