No, he isn't. His article was about transfats. It wasn't about how oils
breakdown in heat. His article had nothing to do with what he said about
heating oil. I was correcting his mistake -- common among vegans and
other nitwits -- that heating turns common vegetable oils into transfats.

Not quite accurate, and overheating oil isn't the only way to cause
problems. Using rancid oils is just as unhealthy. The primary issue with
lipids, though, is creating an environment for free radicals. Free
radicals cause a variety of damage through oxidation, which can lead to
cancer, heart attacks, etc.

Like I said, not quite.

Too much sun is a danger, but so is too little. Don't throw the baby out
with the bathwater. That's one of the dangers vegan activists fall into
-- that because too much of something is bad, therefore any of it is bad.

That, too, is not quite right. The body is able to use transfats just as
it uses other fats. The problem with them is that they suppress HDL, the
good cholesterol, and elevate LDL.

Nonsense. Monounsaturated oils lower LDL and elevate HDL. This is
beneficial in moderating serum cholesterol levels.

That's BS. Solvents used for extracting oils (usually hexane) are
removed by heating the oil. Pseudoscientific ninnies object to that
heating, but it's within ~100 degrees F of the temperatures reached in
mechanical (not so cold in reality) pressing.

That's not the best of advice.

Why would that make you leary? I'm sure you eat processed foods of some
sort. Those are all altered in varying degrees. Everything around you is
"altered."
