This lecture is quick, has good examples and is straight to the point.
B12 is produced by bacteria. Almost all vegans know we have to consume it with supplements, I heard it a thousand times already. We don't need any animal products to have enough B12, stop spreading misconceptions. How about telling about how eating too much purine (daily meat) may causes gout? It's much more common.
clear teaching and repetition, thanks. Learnt a lot. Clinically useful. thanks
