Is palmitic acid "bad," or is this another one of those unsubstantiated claims by status quo?

I've also read sources (like Peter's site I think) that people also often look at diabetics and say "oh look, there's lots of palmitic acid in their blood stream, clearly it got there from eating lots of evil saturated fat. Saturated fat causes diabetuus! Hulk smash!" but too frequently palmitic acid is a marker of overeating, because once you eat beyond what you burn, de novo lipogenesis becomes relevant and turns carbs into palmitic acid. So it's also often falsely maligned for being at the scene of the crime, even though it's likely the energy excess largely to blame for the diabetes.

It isn't bad. If you dig around high-fat-nutrition.blogspot.com and you can handle the sarcasm I think you will find this basic idea:

Palmitic acid seems to encourage insulin resistance, which to the mainstream is always and everywhere bad. Fortunately, for you, your brain isn't mainstream. If there is a lot of palmitic acid around, that usually means there is not a lot of glucose around, so what is really happening here is that the glucose is being reserved for the brain. The parts of the body that can use fatty acids for fuel are being encouraged to do so. So this particular sort of insulin resistance has nothing to do with the big scary 'you are going to get diabetes' kind.

Hopefully someone better read on the subject will chime in. I sometimes get a little lost in the bio-chem stuff.
