Some vegan proponents claim that it is possible to obtain all necessary nutrients without animal foods.
However… this is easier said than done and it seems that many vegans are having problems.
Nutrient deficiencies are much more common among vegans:
- Vitamin B12: 83% of vegans are deficient in B12, compared to 5% of omnivores. B12 deficiency can have serious consequences (59).
- Iron: In one study, vegetarians had only a third of the ferritin (a marker for iron levels) of omnivores (60).
- Vitamin D: Levels of Vitamin D are 74% lower in vegans, compared to omnivores (61).
- Omega-3 Fatty Acids: Vegans have 53% lower levels of EPA and almost 59% lower levels of DHA, compared to meat eaters (62).
A diet that makes the majority of people who follow it deficient in critical nutrients…
