    Can anyone explain this to me? I know atherosclerosis occurs due to plaque build up in the vessels which narrows the lumen and restricts blood flow, but I don't know how salt is involved.

    Before atherosclerosis starts, there has to be damage to the artery wall. This can be from high blood pressure, caused by stress, presence of harmful chemicals in tobacco smoke or salt!

    Salt lowers water potential (aka there's less water). Water moves out of cells in the body by osmosis to raise the water potential as it has been lowered by the salt. Therefore, there is a higher volume of water in the blood, therefore there's a higher volume of blood exerting through the arteries, therefore high blood pressure, which damages the wall. Then your plaque builds up. Hope that makes sense, if not quote me
