According to the New York Times - high HDL is not as good as previously thought.
We Paleohackers tend to have pretty elevated HDL numbers.
So, my question is, does this new study make us reconsider the way that we interpret high HDL numbers?

I cannot believe that other researchers are saying this turns things upside down.
This study doesn't prove anything, beside that being genetically predisposed to having high HDL numbers doesn't necessarily mean you will have high HDL numbers, and see the benefit of those high numbers.
You could be the son of Einstein and be genetically predisposed to be a genius, but you huff glue everyday throughout childhood, something tells me you won't turn out to be a genius.
And, can you believe the head researcher said this at the end of the article?!
???When people see numbers in the abnormal range they want to do something about it,??? Dr. Kathiresan said. ???It is very hard to get across the concept that the safest thing might be to leave people alone.???
Don't do anything? Seriously, just leave everyone alone, that's the best advice for everyone in the world, is don't do anything to try to improve your HDL numbers.
I am almost to the point now when I see a NYT article that I already know I'm going to be enraged by the idiocy.

If I understand correctly:
HDL levels are correlated to heart disease risk (higher=less, lower=more)
Some genes predisposed people to having higer or lower HDL
The new study found that the presence of these genes did not correlate to heart disease risk
Also, taking niacin has been shown to raise HDL levels but in a study taking niacin did not correlate to reduced heart disease risk.
So, what does this mean? Hell if I know. What I'm pretty sure it doesn't mean is that HDL levels are not important. The article stated that low HDL is found in smokers, the obese, and people with metabolic syndrome - 3 things that do correlate to heart disease. These things (unlike your genes) are reversible. And nothing in the study discussed the raising or lowering the HDL in individual people. You may have a gene that predisposes you to high or low HDL, but by quitting smoking or losing weight, you can raise your HDL regardless of your genetic predisposition. Does this reduce your risk of heart disease - yes. Is it because of the HDL? Probably not. The HDL level is likely an indicator of something else going on in the body.
Remember, LDL used to be all bad. Now it's not (even though 75% of doctors haven't gotten that memo - maybe they should read the Times). There is still so much to learn about our internal systems, that we need to stop treating to the numbers.

HDL, LDL and other indicators are hyped up by the Pharmaceuticals so that you will want them and therefore they make billions each year on Statins. If you are on Statins now, look closely at the side effects and the class action suits out there. Your doctors give them to you because they seeminly work, but do they really or are you being fooled.
