The Vitamin B12 Debate

This chapter presents an intense debate about the sources and necessity of vitamin B12, focusing on its production in animals versus its availability in human diets. The dialogue examines modern farming practices, soil deficiencies, and the reliance on supplements, while comparing the B12 intake of omnivores, vegetarians, and vegans. It also discusses the implications of water purification and agricultural practices on the natural availability of B12 in food sources.
