Cholesterol is a fatty substance in the blood and in the body’s cells. The body needs some of it; it helps build cells and some hormones. The worry is “too much”, especially of the kind doctors flag, because it can build up in blood vessels and raise the chance of heart disease. People talk about it with food (eggs, meat, oil), with blood tests, and with medicine. Though actually, the name is a chemist’s name, not a “” name: it was built from Greek for bile plus “solid”, because this stuff was first found as a solid in — stones in the bile. That is why it looks like and on the page, even though in the clinic it is about the heart and the blood, not about anger or that gut disease.
組成Borrowed from French cholestérol. Built from Ancient Greek kholḗ “bile” + stereós “solid”, with the chemist’s ending -ol. Literally a “solid from bile”.

- As we age, the major arteries of our bodies frequently become thickened with plaque, a fatty material with an oatmeal-like consistency that builds up along the inner lining of blood vessels. The reason plaque forms isn’t entirely known, but it seems to be related to high levels of cholesterol inducing an inflammatory response, which can also attract and trap more cellular debris over time.
