Cholesterol is overly berated.
Too low cholesterol is bad for you.
But too high cholesterol is your body's protection system in place trying to protect the arterial walls and arterial structures. If left at too high a level it will then have very serious health implications.
Generally the whole cholesterol issue is based on Big Pharma making money from statins (which are very bad for you). They've integrated themselves into to society so deeply (with the help of GPs being misled and thus spreading the myth) that it will take many many years to dispel it.
It doesn't mean you should ignore choleesterol levels but just know the real facts. Also, too high cholesterol levels can be easily lowered quite fast to a safe and healthy level by eating & drinking healthily.
I recently bought a couple of books:

From this chap - I've got dozens of nutrition and health books as I like to get a broad picture/idea/knowledge. I can't recommend to anyone enough about reading a bit more about nutrition and on how our bodies function.
