I know much more about cholesterol today than I did even two years ago, let alone when I was mindlessly reiterating “standard” cholesterol recommendations to patients years ago. You can’t talk about nutrition without mentioning cholesterol, but most folks (including many of the doctors who tell you yours may be too high) don’t know what cholesterol actually is, let alone the actual risk it portends. I’m going to be doing a lot of writing about the confusion over cholesterol in the future, but I want to very quickly give you a few things to consider.
- Cholesterol is a “waxy” substance generally produced by our liver. Without we could not live, which is to say cholesterol is vital for many functions in our body.
- There are many types of cholesterol particles that vary by size, density, and function
- More often, what people mean when they say “cholesterol” is “lipoprotein,” and these are not the same thing. I’ve tried resisting the urge to include this figure, but I just can’t help it. Below is a figure of a lipoprotein particle. Hopefully you can make out that cholesterol is a part of the lipoprotein, along with other molecules like triglycerides (TG), cholesterol esters (CE), phospholipids, and apoproteins.
