Ultraprocessed foods linked to higher risk of knee osteoarthritis, study finds
Fox News • • general
Key Points:
- A new study from the University of California, San Francisco links high consumption of ultraprocessed foods—such as bacon, breakfast cereals, and pre-packaged snacks—to increased fat buildup in thigh muscles, which may raise the risk of knee osteoarthritis.
- The research analyzed 615 individuals without osteoarthritis using MRI scans and found that greater intake of ultraprocessed foods correlated with more intramuscular fat, regardless of participants’ weight, caloric intake, or exercise habits.
- Intramuscular fat weakens knee support structures, increasing joint stress and inflammation, which contributes to the development of degenerative knee osteoarthritis, a condition strongly associated with obesity and unhealthy lifestyles.
- On average, study participants consumed about 41% of their daily calories from ultraprocessed foods, and researchers suggest reducing this intake could help preserve muscle quality and alleviate knee osteoarthritis risk.
- The study's limitations include its observational design, which cannot prove causation, and reliance on self-reported dietary data, which may affect accuracy.
