Any Vegetarians/Vegans here?

[James2014]

It is an interesting question. I have seen evidence that veganism does change the bacteria that live in the gut, although bacteria are not produced by the gut as such, but rather the change in diet changes the environment of the gut to favour the survival and growth of certain bacteria over others. As to whether this change in diet could result in increased bacteria that produce B12 and so allow them not to require B12 in the diet, I would say this is unlikely as many vegans who do not take supplements or fortified foods become anaemic from lack of b12.

KichigaiNeko, you say veganism is just a preference, but if there are ethical reasons to go vegan, such as reducing suffering of animals, reducing environmental damage, and improving health, then if that is true people SHOULD go vegan.
