Vegetarians and vegans cannot get enough iron
evidence
The Claim
There is a widespread belief that individuals following vegetarian or vegan diets are at a significant risk of iron deficiency because plant-based sources of iron are less bioavailable compared to meat sources. This perception can lead to anxiety about iron intake among those on plant-based diets.
Origin
This myth arises from traditional dietary guidelines that emphasize meat as the primary source of iron, coupled with a lack of awareness about alternative sources and absorption factors.
What Science Says
Research indicates that while non-heme iron from plant sources is less readily absorbed, many vegetarians and vegans can meet their iron needs through careful dietary planning. Studies show that combining plant sources with vitamin C-rich foods can enhance absorption significantly. A review found that with adequate dietary strategies, iron status among vegetarians can be comparable to that of omnivores.
Verdict
Partially True
