I’ve once overheard a conversation in the train where someone said “but cholesterol is good, right? Or are those proteins?” completely unironically. It got a good chuckle from me and several other people in the train.
I eventually learned he was becoming a PE teacher who made diet plans for schools. That was less funny.
Perhaps surprisingly, dietary cholesterol has less an effect on blood cholesterol than a handful of other things. Saturated fat intake/balance in diet correlates more strongly, and vitamin D levels negatively correlates (vitamin D deficiency positively correlates).
Dietary cholesterol is used for a lot of key things such as hormone production, so some people might actually want to increase their cholesterol intake (super active lifestyle people like endurance athletes - can help combat RED-S aka Female Athlete Triad), but the elephant in the room for bad lipid profiles is saturated fats, refined sugars, and sedentary lifestyle
You also need cholesterol in cell membrane structures, hormone synthesis (steroids like testosterone & estradiol), vitamin D, bile acids for digesting fat, and insulating neuron sheaths.

Also, cholesterol is one of the main ingredients our cell membranes are made of.
Dietary cholesterol has little to no effect on blood cholesterol, so indeed cholesterol is good or at least not bad
afaik from youtube, HDL is good, LDL is bad.
Yes.

High cholesterol is “bad” with too much of other fats in your diet, but you need cholesterol to live so your body makes most of it.
E: Correcting the science there, whoops.
The old gag:
Those who can, do
Those who can’t, teach
Those who can’t teach, teach Phys Ed
Those who can’t teach phys Ed, administrate.
Everyone starts somewhere.
Based on the other responses, better to be asking the question than assume he was stupid for asking it.
