The lentils and quinoa thing was just my usual snark. I am neither culturally nor emotionally capable of eating lentils or quinoa in normal conditions. But it is nice to know that I could eat lentils in the event of an apocalypse, without damage to anything but my pride. Thank You.
Lentils are, maybe surprisingly, one of the few foods I kind of miss on keto. There's just something to the starchy, goopy goodness when it's cold out.
That foodulator is great! If we're against PUFA, and we're against protein, then peanut butter is looking like a bad actor indeed. I wonder when I first started to eat the stuff. It might not be just chips that were my downfall.
I *am* thinking like an economist. I've taught (classical micro-) economics!
Of course protein can be bad for you. You could e.g. be hit by a falling block of it. I am speaking a little loosely.
But if you're in an environment when you can get hold of it easily, as many creatures must have been, and eating it is bad for you, and you eat it anyway and die, then you don't leave descendants.
Ancient systems can't have show-stopper bugs in normal conditions.
The same argument doesn't apply to linoleic acid because never ever in our history since we were apes have we had a source of linoleic acid in large quantities. Except possibly olive oil, which maybe some people who weren't ancestors of mine maybe ate a lot of in the last two thousand years. And even Olive Oil is not very high in linoleic acid.
Did the ancient Greeks ever get 30% of their calories from the linoleic acid in Olive Oil? I have no clue, but it seems unlikely. Were there unusual numbers of obese classical Greeks? I have no clue. Did it affect their breeding success? I have no clue. Is two thousand years enough time to evolve a distaste for olive oil? Yes, I would think so, if the effect was strong.
Do the descendants of the Greeks tolerate linoleic acid a bit better than most people? I have no clue, but I wouldn't be surprised.
Also maybe eskimos. There's linoleic acid in seal blubber, I think. And I think Brad said something about how they can't go into ketosis. That's a hell of an adaptation, and it's in the form of something useful breaking, which is the usual form of hasty emergency adaptations.
Design defects aren't stable. Evolutionary time is long, but if there's pressure, bugs that are a problem get fixed.
The programmer is an idiot, but the test suite is solid, and management is very results focused.
> Water is essential, so drowning isn't real?
Water is essential and ubiquitous, and so it is beloved in the necessary quantities and it is very hard to consume more than is good for you.
Drowning is real, and so the experience of inhaling water is so aversive that it is used as a method of torture.
Yea, Brad and Amber were talking a while ago how the Eskimos might have developed a protective mechanism against all the PUFAs in the cold water fish and seals they were eating, which might involve not getting into (deep) ketosis.
But there's very limited data on this, a lot of the older studies I've seen were just pretty much trash, as in, they didn't measure ketosis correctly, and made a ton of assumptions that, in hindsight, are probably all false. Like, "Eskimos are not in ketosis, therefore meat must contain tons of glucose." Based on 1 sample of a couple dozen people or so, of one tribe. Apparently there is now a little bit better data which might support this weird genetic adaptation.
Of course, everyone is interpreting it according to his favorite paradigm: "Ketosis is so toxic, the Eskimos evolved a gene not to get into it!" "PUFAs are so toxic, the Eskimos evolved a gene to protect against it!"
> "Ketosis is so toxic, the Eskimos evolved a gene not to get into it!"
That's silly. Ketosis may well be a bad state compared to normal metabolism when there are carbs around, but to me, it looks like a way of surviving in a low carb environment that would otherwise kill you for lack of brain-fuel. The last people who are going to ditch that emergency backup mechanism are people living permanently in a low-carb environment.
> "PUFAs are so toxic, the Eskimos evolved a gene to protect against it!"
This I can believe, but only just. PUFAs so bad that the best easily found mutation to survive eating them is to break an important part of your fat metabolism in an environment where fat is the main resource, and the selective pressure so strong that the breakage will sweep before whatever the sensible way to adapt to high-PUFA diet sweeps.
But if it's true, then PUFAs have to be very bad indeed, and with no straightforward adjustment to a high-PUFA diet already under genetic or even cultural control!
Big if true.
And it immediately leads one to ask: "So what on earth were the eskimos living on? What powered their brains?" Glucose from blood? Gluconeogenesis from the proteinous bits of the things they hunt? Sea-honey from as yet undiscovered submarine ice-bees?
Intruiging! Further research is needed!
It might explain why the Greenland colony died out while surrounded by food and people who could have shown them how to get it. Maybe they did try eating the local food but it didn't agree with them.
My favorite use for the Foodulator(tm) is to spot-check myself and others right away, which now takes a second instead of a minute:
Peanut butter has over 12g of LA per 100g - truly insane:

Quinoa is actually quite high in LA. If you get all your calories from quino, 7-8% of them will be from LA, far too high:

Lentils are only 1.1% kcals from LA:

You can thus eat them ad libitum and be PUFA-safe.
> Protein cannot be bad for you.
This sort of pre-maginal thinking is toxic in nutrition. Reeee, how could linoleic acid be bad for you, it's ESSENTIAL!
