iron-red-blood-cells

1. Why is iron important for our health?

Iron is an important component of haemoglobin. Haemoglobin is the part in red blood cells that carries oxygen.
If you don’t have enough iron, your body can’t have enough oxygen-carrying red blood cells.
A lack of red blood cells is called iron deficiency anaemia.

2. Should we then get as much iron as possible?

No, excess iron in the blood increases our risk of:
– cancer
– diabetes
– heart disease
– stroke
– neurodegenerative diseases, such as Parkinson’s disease and Alzheimer’s disease

3. How can we avoid having too much iron?

Consume only nonheme iron (iron from plant sources – heme iron comes from animal sources).

Our body has difficulty removing excess iron, so our small intestine tries to block excess iron absorption. However, it is able to block only the nonheme iron (plant iron). Heme iron (from animal sources) may not be blocked. Therefore, it is easier to get iron overload from heme iron.

There is also a growing concern over a strong link between heme iron and cancer.

4. How can nonheme iron (from plant sources) be well absorbed into our body?

Consume Vitamin C in the same meal as the iron rich meal. For example, include an orange with an iron rich meal.

Iron Molasses Orange Juice 330x215

5. What’s a good solution for anaemia?

Try freshly squeezed orange juice sweetened with molasses (which contains lots of iron)
Take Vitamin C with iron rich foods (click here to see the iron content of various foods).

6. What can improve iron absorption?

Avoid caffeine for at least 1 hour after an iron rich meal, as caffeine can interfere and reduce iron absorption by 60-90%.

Soak Chickpea

Soaking beans can help increase iron absorption by 300% to 1100%, as unsoaked beans have phytic acid which inhibits iron absorption.
