The belief "veganism is natural for humans" is not harmless. There don't seem to be any bioavailable plant-based sources of b12. If you were to live that belief, you can get permanent nervous system damage vegansociety.com/resources/nut

"There is only one reliable test for a B12 source - does it consistently prevent and correct deficiency?"

"A study from Tufts University found that 40 percent of people between the ages of 26 and 83 have plasma B12 levels in the low normal range, a range at which neurological symptoms can occur"

aaa wtf he recommend a dose 5x higher than what I'd get from the average pill here (he recommends at least 250mcg) but doesn't cite that part

Show thread

Dr Greger advocates 50mcg on one page nutritionfacts.org/topics/vita and 250mcg (or 2500mcg weekly) on another nutritionfacts.org/2011/08/30/
I'm gonna call it for 250 I guess

@faun My understanding is that many recommended doses are spitball and convention. How much stock do you put into this guy's words? B12 is water soluble so I'd think high dosage recommendations could be made rather flippantly, but it's not a topic I'm very familiar with.

@bee because he didn't cite anything (therefore hate) I'd be willing to dismiss him for dr greger right now, but I think greger agrees with him (at least, has. I can't tell what the chronology is between the two things greger has said)

@faun Are we not in danger of committing an Appeal To Nature Fallacy here? Even so, factory farming isn't "natural" either. Living this belief causes harm to people and planet too. Maybe its more helpful to recognise that in today's food system either you consume animals (who themselves must often consume a b12 supplement) or eat plants and take the supplement yourself. I'd say the latter is better all round, no?

@ClearMask I would hope that we are never in danger of committing the naturalistic fallacy in merveilles. It has no no place here.
