## Iron Intake Recommendations
Iron is essential for oxygen transport in the blood. Requirements vary by age and dietary pattern.
### RDA for Males
| Age | RDA |
|---|---|
| 1-3 years | 7 mg |
| 4-8 years | 10 mg |
| 9-13 years | 8 mg |
| 14-18 years | 11 mg |
| 19+ years | 8 mg |
Vegetarians need 1.8x more iron because plant-based (non-heme) iron is less readily absorbed.

Exemplo Resolvido
A 30-year-old omnivore.
- Age 19+ base iron = 8 mg
- Omnivore multiplier = 1.0
- Daily iron = 8 x 1.0 = 8.0 mg
- Upper limit (adult) = 45 mg
