cholesterol is an interesting one
this medical article talks about LDL being the "bad" cholesterol that can clog your arteries.
http://www.webmd.com/cholesterol-manage ... l-overviewbut my understanding is this, your arteries wno't clog up unless the walls are first damaged and roughened up, usually by damaged or oxidised fat, and vegetable fat is highly likely to be the fat that does that and it can also damage the LDL , LDL cholesterol increasing the likelihood of it sticking to your artery walls, and so LDL gets the bad rap because it is the one that ultimately is seen to clog the arteries....
you've go some vegetable oil at home, if its high in polyunsaturated oil and you've spilt some around the lid or down the side of the container and left it there then it will go hard and or sticky, thats oxidised, thats what it will be like in your arteries, mixing in with saturated fat and cholesterol increasing the chances of it sticking to your arteries,
vegetable fat is more likely to harden your arteries over the years as well , as you age your immune system isnt very good at arresting the damage it can cause....
