Episode notes
Iron Deficiency Is Widespread And Critical
- Iron deficiency affects over 25% of people worldwide and is common even in developed countries.
- Iron is essential for red blood cells, oxygen transport, energy, immunity, and muscle oxygen storage.
Choose Heme Iron When Possible
- Prefer heme iron from animal foods when possible because the body absorbs it more readily.
- Recognize that non-heme iron in plants is less well absorbed and may require dietary adjustments.
Increase Intake During High‑Need Life Stages
- If you have higher iron needs (pregnancy, growth, heavy exercise), increase dietary iron or consider supplements under medical advice.
- Ask your healthcare provider about testing and monitoring during these high‑need life stages.
