Ultraprocessed foods are turning human thighs into well-marbled steaks
Researchers found 615 adults who ate more ultraprocessed foods had more fat in thigh muscles, even after accounting for BMI, calories and exercise.
- On Tuesday, a study published in the journal Radiology found that consuming ultraprocessed foods is linked to increased fat marbling in thigh muscles, analyzing MRI scans from 615 people.
- Ultraprocessed foods are often nutrient-poor, potentially driving fat accumulation in muscle fibers and streaks, which alters muscle structure and contributes to knee osteoarthritis.
- One 61-year-old woman consuming 87.1% ultraprocessed foods showed dramatically more fat marbling in her thighs than a peer with a 29.5% ultraprocessed diet and higher BMI.
- Radiologist Dr. Miriam Bredella of NYU Langone Health noted this is a systemic process impacting muscles throughout the body, with increased intramuscular fat linked to cardiovascular disease and Type 2 diabetes.

Study links ultra-processed food intake to poorer thigh muscle quality
A Radiology study of 615 adults at risk for knee osteoarthritis found that higher ultra-processed food intake was associated with greater fat infiltration in thigh muscles on MRI, a marker of poorer muscle quality. The association remained after adjustment for BMI, was stronger in models using abdominal circumference, and did not differ significantly by sex.
Researchers at the University of California in San Francisco, United States, have found that a diet rich in ultra-processed foods is associated with increased accumulation of fat in the thigh muscles, regardless of calorie or fat intake, physical activity, or sociodemographic factors in a population at risk of knee arthrosis.Read more]]>
Ultra-processed foods are a quick and easy option to prepare and so they are often added to the supermarket cart. In addition, they often have a longer service life and allow you to eat them away from home. However, they contain a combination of sugar, fat, salt and carbohydrates that affect the brain reward system, which makes it difficult to stop eating. Examples of them are cereals, margarines, packaged snacks, hot dogs, soft drinks and energ…
