Greetings - If you watch the videos linked in the post here, you will see the advice regarding 'harm minimisation' - however, since there isn't generally speaking a need for most people to eat meat anyway - I see no reason to eat it in any amounts. Some say that it is not possible to obtain Vitamin B12 without eating dead animals - however, that is a position that denies numerous things, such as that modern farming practices cause both depletion of B12 from plant foods and also kill off B12 in animals too. Additionally, the issue is not so much the amounts of B12 involved anyway - rather it is the ability to absorb it that is the issue.. This can be improved through correct protocols.
