Good answers. LDL, the low density lipoprotein, carries cholesterol out to the body. High density lipoprotein (HDL) picks it up and brings it back to the liver for metabolism. The higher the HDL and the lower the LDL the better off you are. Less cholesterol delivered to tissues, more returned for metabolism.
There is so much conflicting information now on cholesterol, that I am not sure how to sort it all. But what there is solid info on is that sedentary lifestyle combined with high fat/high calorie diet, smoking, alcohol abuse, family history, etc. does appear to increase the risk of multiple disease scenarios. Until the CDC or NIH changes their position on cholesterol, I will be following their recommendations when clients ask for my opinion.
A lot of what we think we know about cholesterol and heart disease has changed over the last couple of years. One of my clients is a medical director for a health insurance company and she has told me that (a) the link between the two isn’t solid and (b) the incidence of side effects with statins (cholesterol meds) is higher than the risk of heart disease directly related to cholesterol.
“there are SO many excellent sources of solid scientific information to debunk the idea that cholesterol IS the enemy
mostly it’s inflammation actually
so “. the quoted studies that half the victims of heart attacks have normal to low cholesterol is a very solid evidence base..
there are many more you could find if you wanted to“but these are true
the actual fact about statins—it’s clear they cause about as many new cases of diabetes as they might reduce the risk of heart attacks— I can send you an article on number to treat if you want.. but that is the bottom line”
There is a very strong correlation. Here is an article with great details.
