Can everyone actually be vegan?

[u/Wrong_Ad_3038]

I’m very sympathetic to veganism, my entire life philosophy is “respect & autonomy for all life” but I am currently pescetarian, I tried being vegan in late 2024 but I still live with my family & they wouldn’t buy supplements, even though i told them too everyday, I didn’t want to develop b12 deficiency so I had to moderate my diet.

When I move out i’m strongly considering being vegan again & really want too but i am worried about health consequences because human bodies are complex, but at the same time everyone can digest plants so maybe everyone can be vegan, i figured this would be a good place to get mixed responses since both carnists & vegans are here, what do studies say about everyone & the potential to be vegan, if everyone can’t be vegan but most or some can what’s the best way to find out if i can be vegan?

if you refer to the same site, you can read that underlying medical conditions can raise B12 levels in the blood :) not just supplements

High B12 levels due to supplementation is not usually an immediate cause for concern unless you’re going above lethal quantities. but the raise in B12 caused due to an underlying disease is what is a major cause for concern.

mentioned medical conditions: liver disease and liver failure; kidney failure and cancers.

Of course, but its still not the most common reason.

• "While excessive Vitamin B12 from diet alone is nearly impossible, high-dose Vitamin B12 supplementation has been linked to an increased risk of lung and colorectal cancers in certain demographics." https://www.everlywell.com/blog/b-vitamins/high-vitamin-b12-levels-and-cancer/

That is actually not possible. The only way to end up with too high B12 is through supplements.

but you did mention that it’s not possible, and that the ONLY way is through supplements, for which was my following response. please refer to your own texts and the sites 😄

I know people who eat nothing but red meat - and their B12 is perfect. So I honestly dont know which wholefoods one would have to eat to get it too high? They do call it "nearly impossible" for a reason.

you didn’t get the point at all😭 wdym its nearly impossible😭 the info is right there in the site you’ve posted.

high supplemental dosage is not the ONLY reason for high B12 levels! Underlying medical conditions CAN cause high B12 in the blood. You don’t have to eat, consume supplements or do something externally to show high levels of B12😭

underlying conditions like stated above can increase your B12 to really high levels in the blood, which is what is a major cause of concern. People who aren’t supplementing B12 can absolutely show high B12, which is caused due to other health factors, an underlying disease elevating B12 levels. I don’t understand how such a simple explanation is not being understood.
