Excuse me, because I know this has been dealt with many times before, but I'm rather confused. The Definitive Guide to Cholesterol post on this site outlines cholesterol as okay (That's what I take from it anyway, I find it hard to follow; All the termonology!). I read a book called The Great Cholesterol Con by Dr. Malcom Kendrick ( http://www.amazon.com/Great-Choleste.../dp/1844543609 ) which basically says that pretty 'high' cholesterol (I think it's about 5.5 mmol/L) is ideal. But in contrast to these almost everything I've seen (even here) involves people getting worried because of high cholesterol levels.
So my question (and I'm sorry it took so long to ask!) is this: How do cholesterol levels really matter? Is high cholesterol good or bad?
