Michael Greger: Are the Lower Iron Stores in Vegetarians a Risk or a Benefit?
Peer-Reviewed Research
Key Takeaways
- Monitor ferritin levels – Aim for 15-50 ng/mL (optimal range), avoiding both deficiency (<15) and excess (>50).
- Consider blood donation – Reduces iron stores, lowering diabetes risk by 40% and cancer mortality by 60% in trials.
- Prioritize plant-based diets – Vegetarians naturally maintain lower (healthier) iron stores vs. meat-eaters, reducing oxidative damage.
Notable Quotes
“Iron is a double-edged sword… levels above 50 are associated with disease.”
“Reducing one’s iron stores appeared to rapidly decrease cancer development.”
Bottom Line
Get a ferritin test, donate blood if levels exceed 50 ng/mL, and shift toward plant-based eating to optimize iron stores for longevity.
