This is all fantastic news, and it's a reason why I believe saturated fats to be by far the healthiest fats one can consume.

The fact that SFA's inhibit omega 3's as well is more great news. I see no health benefits to omega 3's. Studies showing epidemiological benefits are full of confounding factors - the main one being that societies that eat lots of fish tend to eat less processed foods in general. I don't think it's the fish consumption helping, but rather the avoidance of frankenfoods. On the other hand, every day that goes by shows fish oil supplementation to be more and more toxic and cancerous. Keep the omega 3's even further away from me than the omega 6's since omega 3's are longer chain, and therefore more fragile and prone to oxidation/trans-fat conversion/free radical damage.
The only fats I use to cook with anymore are pastured butter/ghee and virgin coconut oil. I'm cool with extra virgin olive oil, but it's so hard to find the "real stuff" anymore I limit its use. If you can find good quality California olive oil that is deep green, solidifies in the fridge and burns on the way down, I say have at that, too. I wouldn't consume any other oils other than those three by choice.
Don't put your trust in anyone on this forum, including me. You are the key to your own success.
