High-fat meals and endothelial function

Two recent studies on the effects of single high-fat meals on endothelial function have postulated an additional mechanism by which dietary lipids can impact atherosclerosis. These studies found that dietary lipids decrease the ability of blood vessels to dilate and that this modification of endothelial function was protected by dietary antioxidants. Although this research presents an interesting hypothesis, much more research is necessary to determine the importance of dietary factors on vasoactivity.
