Well, it's all about "markers," which are contextual, so it really doesn't mean much to you or me specifically. I suggest you read the essays on this site, along with the posts in the forums that interest you, and then ask questions you may have at that point. It's very easy to "drive yourself crazy" if you fixate on one study or a small number of them. Instead, they key is to keep an open mind and gradually "fill in the blanks" in your understanding. If you "get stuck," you can ask me questions at that point. You will learn a lot more by struggling to conceptualize things, rather than have someone explain some minor point that may be irrelevant or impossible to determine the significance of, given the limited amount of evidence in some areas.
In general, I'll say that many studies today focus on the LDL-lowering effects of this or that substance. This is only relevant in the heart disease context if your cells are loaded with arachidonic acid and your diet/lifestyle is oxidizing. If not, as is the case with myself, you want your LDL to be "high" according to typical standards in the USA. If it is "off the charts" high, that would be an indication that something is wrong, but today marginally "high" means healthy, not unhealthy, especially as you get older (again, if you avoid oxidizing issues). |
