Scientists have claimed that taking regular exercise helps to rid the bloodstream of molecules from unhealthy food.
The University of Glasgow researchers found that exercise changes the make-up of lipid blood fats, which boosts the process of clearing them from the body.
A total of 12 overweight and obese men were put on treadmills during the research, which was published in the American Journal of Physiology, Endocrinology and Metabolism.
Too many bad lipids - such as LDL cholesterol - have in the past been linked to raising a person’s chances of suffering a stroke.
People who have diets containing lots of fatty foods often suffer from high cholesterol, previous research has shown.
Study leader Dr Jason Gill, from the University of Glasgow, said: “Our research suggests that exercise works at the ‘plughole’ end of the process, increasing the body’s ability to break down the fats faster.
“We think this might occur through structural changes to the lipid particles making them more amenable to clearance from the blood.”
