When Indians who follow a strict vegan diet started migrating to the western world, a lot of them would begin to suffer from pernicious amaemia, a disease caused by deficiency of dietary vitamin B12. Similar diseases are present in India but appeared to be less common.
Most published research are rather diplomatic about this phenomenon[0]. However, reading between the lines, the reason appears to be the lack of fecal and insect contamination in food supply, which accidentally eliminated a lot of exogenous micronutrients not present in plants.

- Laforet 8y agoI use the term loosely in reference to all types of anaemia arising from cobalamin deficiency, as the NIH and Mayo clinic do[0][1]. After all, lack of IF is only one of the many causes and the symptoms are similar regardless of aetiology.
