Eating lots ultra-processed foods could leave you at higher risk of a debilitating bone-thinning disease, concerning research has suggested.
Additive-laden foods like crisps and sweets have been vilified for decades over their supposed risks, with dozens of studies linking them to type 2 diabetes, heart disease and cancer.
Experts have even called for ultra-processed foods (UPF) — typically anything edible that has more artificial ingredients than natural ones — to be slashed from diets.
Now, US scientists who tracked over 600 overweight Americans, discovered those who ate more junk food had higher amounts of fat stored inside their thigh muscles.
The amount of calories in the foods made no difference to the effect.
Diets high in UPFs even impacted muscle quality regardless of how much exercise participants did.
The team argued their findings echoed calls to limit certain types of UPFs and warned that higher amounts of fat in the thigh muscle could increase the risk for knee osteoarthritis.
Dr Zehra Akkaya, a radiology and biomedical imaging researcher at the University of California and study co-author, said: 'The novelty of this study is that it investigates the impact of diet quality, specifically the role of UPFs in relation to intramuscular fat in the thigh muscles assessed by MRI.'
