What Should I Eat If I Have Iron Deficiency?
Quick answer: Eat iron-rich foods alongside vitamin C to boost absorption. Avoid calcium-rich foods, tea, and coffee around iron-rich meals, as these block absorption.
What to Eat
Red meat (beef, lamb)
Haem iron — the most bioavailable form, absorbed 2–3× more efficiently than plant iron.
Liver and organ meats
Extraordinarily high in haem iron — 100g of liver provides 6–9mg (50–80% of daily needs).
Lentils and beans
Excellent plant-based iron source; pair with vitamin C foods to maximize absorption.
Tofu
One of the best plant-based iron sources — 100g provides ~3mg iron.
Spinach and dark leafy greens
Good iron content; pair with lemon juice (vitamin C) to overcome oxalate inhibition.
Pumpkin seeds
30g provides ~2.5mg iron — easy to add to salads, yogurt, or eat as a snack.
Quinoa
Contains both iron and protein; gluten-free and versatile.
Fortified cereals
Many breakfast cereals are fortified with 100% daily iron — check labels.
Dark chocolate (70%+)
Surprisingly good source of iron — 30g provides ~3mg.
Vitamin C foods (bell peppers, citrus, kiwi, broccoli)
Dramatically increase non-haem iron absorption — always eat together with plant iron sources.
What to Avoid
Tea and coffee around meals
Tannins bind to iron and reduce non-haem iron absorption by up to 60% — wait 1 hour after eating.
Calcium-rich foods during iron meals
Calcium competes with iron absorption — separate dairy by 1–2 hours from iron-rich meals.
High-phytate foods (bran, whole grains in excess)
Phytic acid binds non-haem iron; soaking/fermenting reduces this effect.
Antacids with iron-rich meals
Reduce stomach acid needed for iron absorption.
Excessive fibre supplementation
Can bind iron in the gut — stick to food sources of fibre rather than supplements.
Hydration
Stay well hydrated, but avoid tea or coffee for at least 1 hour before and after iron-rich meals. Water is ideal. Orange juice with meals is actually beneficial — the vitamin C boosts iron absorption.
Tips
- •Always pair plant-based iron with vitamin C in the same meal (lentils + tomatoes, spinach + lemon dressing).
- •Cook in cast-iron cookware — small amounts of iron leach into acidic foods like tomato sauce.
- •If prescribed iron supplements, take on an empty stomach with orange juice for best absorption.
- •Vitamin A also enhances iron absorption — sweet potato and carrots are good companions.
- •Get a blood test (ferritin, haemoglobin, transferrin saturation) to track progress — symptoms can lag behind blood levels.
