I thought this was interesting. Why would Paleo eaters be deficient? Are there that many people with gut issues, low stomach acid, anemia, and alcohol and nitrous oxide use?
Quote:
The absorption of B12 is complex and involves several steps – each of which can go wrong. Causes of B12 malabsorption include:
intestinal dysbiosis
leaky gut and/or gut inflammation
atrophic gastrits or hypochlorhydria (low stomach acid)
pernicious anemia (autoimmune condition)
medications (especially PPIs and other acid-suppressing drugs)
alcohol
exposure to nitrous oxide (during surgery or recreational use)
This explains why B12 deficiency can occur even in people eating large amounts of B12-containing animal products. In fact, many of my patients that are B12 deficient are following a Paleo diet where they eat meat 2-3 times a day.
