I refer to this question by a new user to Biology-SE site. It was closed as being "unclear what you're asking".
It seems to me, whatever else, it is very clear what is being asked: What do the terms 'good cholesterol' and 'bad cholesterol' refer to?.
For example, the Mayo clinic has this to say about 'good' and 'bad' cholesterol:
Low-density lipoprotein (LDL). LDL, or "bad," cholesterol transports cholesterol particles throughout your body. LDL cholesterol builds up in the walls of your arteries, making them hard and narrow.
High-density lipoprotein (HDL). HDL, or "good," cholesterol picks up excess cholesterol and takes it back to your liver.
Other examples of the use of these terms may be found at the following sites: HDL (Good), LDL (Bad) Cholesterol and Triglycerides (The American Heart Foundation), LDL and HDL Cholesterol: "Bad" and "Good" Cholesterol and Is there really such a thing as ‘good’ and ‘bad’ cholesterol?
What is the justification for closing this question? It is surely the type of question that this site should be trying to attract?
Secondly, why be so unwelcoming to a new user? One of the comments is 'You can't get cholesterol from vegetables', which is at best misleading (vegetables do contain cholesterol, just not very much, and plant membranes contain cholesterol), but (IMO) is also unnecessarily hostile.
One of the most popular stackoverflow questions is How to exit the Vim Editor, making up around .005% of question traffic (see here for a commentary). It has been viewed over 1.4 million times. The answer is freely available elsewhere (:help quit, from within Vim, for example), but is would seem that programmers use Google whenever they have a difficulty, and SO is the 'go-to' place. It seems to me that Biology-SE has a lot to learn in this regard.
It is surely reasonable that the OP be given a reasonable hearing, that the question be interpreted in the spirit it was asked, and that the SO community provide answers in a welcoming and friendly manner?
Finally, let's consider things from the viewpoint of a new visitor who uses Google to search for 'good and bad cholesterol' and compares the quality of Biology SE to that of (say) the American Heart Foundation. In this instance at least, we are not the 'go-to' place.
