Until now, however, much of the research focused on oxycholesterol's results in damaging cells, DNA, and its biochemical impacts in contributing to atherosclerosis. Chen believes this is among the very first studies on oxycholesterol's results in raising blood cholesterol levels compared to non-oxidized cholesterol. In the brand-new study, Chen's group measured the results of a diet plan high in oxycholesterol on hamsters, frequently used as surrogates for humans in such research.

The oxycholesterol group showed greater deposition of cholesterol in the lining of their arteries and a tendency to establish larger deposits of cholesterol. These fatty deposits, called atherosclerotic plaques, increase the threat for cardiovascular disease and stroke. Most notably, according to Chen, oxycholesterol had unwanted impacts on "artery function." Oxycholesterol decreased the elasticity of arteries, impairing their ability to expand and bring more blood.
However a healthy diet abundant in antioxidants can counter these effects, Chen said, noting that these compounds may block the oxidation process that forms oxycholesterol. Great sources of anti-oxidants include fruits, veggies, beans, and specific herbs and spices. Healthy options to fast-food, which also improves oxycholesterol, include whole grains, fresh fruits and vegetables, seeds, and nuts.

The etiology of atherosclerosis is intricate and multifactorial however there is extensive evidence indicating that oxidized lipoproteins may play a key function. At present, the website and mechanism by which lipoproteins are oxidized are not solved, and it is unclear if oxidized lipoproteins form in your area in the artery wall and/or are sequestered in atherosclerotic lesions following the uptake of flowing oxidized lipoproteins.

Thus, the purpose of our work has been to identify in people whether oxidized dietary oxidized fats such as oxidized fats and oxidized cholesterol are taken in and contribute to the swimming pool of oxidized lipids in flowing lipoproteins. When a meal containing oxidized linoleic acid was fed to normal topics, oxidized fats were found only in the postprandial chylomicron/chylomicron remnants (CM/RM) which were cleared from flow within 8 h.
