"it wouldn’t be possible to get Vitamin B12, which is only available in animal products." Marmite? http://en.wikipedia.org/wiki/Marmite

> vitamin B12 is not naturally found in yeast extract, but is added to Marmite during manufacture

Perhaps it would be more accurate to say that it can't be found in plants, but it can be found in animals and it can be produced industrially.

And nutritional yeast etc.

But first you have to get to brewing/fermenting, which isn't a year round process until you have leveled up on a bunch of other skills

There is an awful lot of dog-whistling in this article. Gorilla stupidity and dead malnourished babies caused by not eating meat! The author tacks on "oh but plant-based diets can be healthy now" at the end but the overall message is deceptive and sensationalist.

This is irresponsible journalism.

(Some) nutritional yeast is fortified with vitamin B12. It's not a natural component.

Hopefully folks reading this article won't take it to mean that humans still need to continue consuming large amounts of meat. Maybe it was necessary to eat meat and hunt to evolve large brains, but the negative economic & ecological impacts of eating meat are pretty well-documented by now. I am thinking here of the "meat industrial complex" that powers a lot of large commercial meat production, not the friendly sust…

This conflates at least four issues: 1. Is is healthy to eat meat? 2. Is it right to eat meat? 3. Is it healthy to eat sustainable organic meat? 4. Is it right to eat sustainable organic meat? Accepting that the 'meat industrial complex' is bad doesn't automatically imply vegetarianism/veganism. In particular, I'm thinking of Joel Salatan's brand of sustainable agriculture and permaculture.

The original article also conflates vegan and raw diets. I am a vegan who enjoys cooking and often eats highly processed foods; in my present environment (San Francisco), I'm faced with the health challenge of getting far too many calories every day, not too few. In fact, creative food entrepreneurs keep making this challenge worse and worse for me!

I would readily accept that almost everything about my life is drastically different from the environment in which my ancestors evolved. Those differences seem to have both positive and negative ethical and health consequences.

Have there been vegans claiming that veganism is natural, and that this is somehow a reason to be vegan? Because that would be dumb. Veganism is an ethical stance, after all, so I'm not sure on what basis that argument would even rest.

Also, archaeologists who don't know about nutrition should probably not talk about nutrition as if they did. There are plenty of non-animal sources of B12, including soil (you know, where vegetables grow?).

People who I met traveling in the south of India were shocked to find out that I eat meat every day or even multiple times a day. Even those who eat meat in India do so springy. I too took to that way of life and now am pretty much a vegetarian who cheats with seafood every so often. Feels good.

Resolving this is challenging. I've been on a ketogenic diet for the last several months, and while intellectually I recognise that eating mostly plants is more sustainable and has a lower carbon footprint, I have also never felt healthier than while eating larger amounts of fat and meat. My blood sugar is normalised, I generally have more energy and endurance and have effortlessly lost weight in the process.

I also find it hard to resolve the ethical dilemma of eating meat when my body responds so favourably to consuming animal fats. I think the least one can do is to make an effort to try to source locally produced free-range products, but sadly this is difficult for many as it's expensive or simply not available.

Earlier (and perhaps more impactful) research in this area: http://www.jstor.org/discover/10.2307/2744104?uid=3739936&#3...

The tradeoff between digestion and cognition suggests that adaptations are rarely cost neutral, and explains why random traits don't just improve forever. (ie, why we don't all have eyes like hawks).
