I am with you on this. A high cholestrol is not good for you.
As with all things in life, take everything in moderation, carbs, fats , calories, fibre etc and remember we are all different.
High cholesterol isn't good for some, that is true. However, people with high cholesterol have had CAC scans done and have been shown to be clear of disease. So, the idea that it is automatically bad just doesn't hold up. This is where difference comes comes into play I think.
I think if someone has a history of heart disease or is concerned about it, a scan is the best diagnostic tool available and it's rather cheap, but it is very accurate because it looks into the arteries and is non-invasive. Without the ratios and fasting, total cholesterol is a poor marker, as is LDL, but the ratios are important and so are the trig levels. These just give an indication of things per blood test that day. It doesn't mean you have heart disease and it doesn't mean you don't if you have accumulated damage over the years, but changed your diet to a healthier one.
I think if someone really wants to know, then a CAC scan is the way to go.
