Name even one that cannot be sourced except from animals.

Micros:

- Vitamins: A, B[1,2,3,5,6,7,9,12], C, D, E, K

- Minerals: Ca, P, Mg, Na, Cl, K, S

- Trace minerals: Fe, Mn, Cu, Zn, I, F, Se

Or even macros:

- Glucose

- Fiber

- Lipids

- Essential amino acids (EAA's): his, ile, leu, lys, met, phe, thr, trp, val

- Conditionally-essential amino acids (CEAA's): arg, cys, gln, gly, pro, tyr

Your definition of "extreme" is extremely dishonest FUD.

[femiagbabiaka]

Not dishonest, and not FUD. I'm simply stating the obvious -- we have cultural norms around a balanced omnivore diet that happen to include a lot of these micro and macronutrients. Most people don't even think about it and will only be deficient in a subset of micros. When people swap to veganism or vegetarianism they don't have the same cultural norms to fall back on and struggle to fulfill micro and macronutrients, which results in stories like the one upthread. It doesn't do your cause any favors when you ignore people's suffering from lack of nutrition while trying to swap onto it.

As far as the extreme label goes, any highly restrictive diet is extreme. Veganism, carnivore, keto, etc.

You still don't get it. Whatever you're going on about is only "obvious" to you. "Cultural norms" are your judgements and your biases. There is no mandate to "suffer" from a "lack of nutrition," millions and millions of people are vegetarian and just fine. I'm one of them. My CBC and vitamin panel came back as 100% normal.

Meat agriculture is killing us slowly like cigarettes and cancer, and kills us quickly.

1918 most likely zoonotic route:

Birds -> pigs (at a "piggery") -> humans.

2019 SARS-CoV-2 most likely zoonotic route:

Bats -("wet market")> humans.

You seem to emphasize edge-case FUD and "other" people who don't agree with your value judgements rather than opening your eyes to meat agriculture as a slow-moving existential threat to our survival like and causing climate change.

It's very unfortunate that you're so narrow-minded.

[TheCoelacanth]

They didn't say "cannot be sourced except from animals". They said "easy to miss out on". You're arguing against a strawman.

Anyone switching to a vegan diet certainly would be well-advised to pay attention to micro-nutrients and make sure they have their bases covered.
