The Claim
Adults who consume vegetarian diets have significantly lower serum ferritin levels and a higher risk of iron deficiency compared to adults who consume omnivorous diets, despite frequently ingesting greater amounts of total dietary iron, primarily due to the lower bioavailability of non-haem iron found in plant-based sources.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Even if vegetarians eat more iron than meat-eaters, they might still be more likely to be low on iron because the kind of iron in plants isn't as easily absorbed by the body.

What the research says
1 studyThe study looks at whether eating meat helps people have healthier iron levels, and it found that people who eat meat tend to have better iron status, which supports the idea that vegetarians might be more likely to lack iron.
