Understanding Integral Iron
Did you know that iron isn’t naturally made in the body and that we only absorb it from what we eat? It’s kinda crazy considering that it’s a pretty important mineral for making haemoglobin (a protein contained in red blood cells that transports oxygen around the body).
Put simply, there are two main forms of dietary iron: haem iron and non-haem iron. Haem iron is typically found from animal products (your red meats, fish and poultry) whilst non-haem is the opposite and more plant-based (your chickpeas, beans and dark green leafy veggies.) Iron can also be found in fortified products such as breakfast cereals or flour, however always read the label to make sure.
Haem iron is your body’s preferred source of iron as more of it is easily absorbed. Some studies have shown that consuming foods high in vitamin C alongside a meal can actually increase your iron absorption, so pour that glass of orange juice or make your dessert a fruit plate filled with strawberries, clementines, cherries etc.
So… how much do you recommend?
- - 8.7 mg/day for men (over the age of 18).
- - 14.8 mg/day for women (aged 19-50).
- - 8.7 mg/day for women over 50.
For healthy individuals you should be able to get all the iron you need through your diet if it is varied and balanced. Menstruating females can sometimes be at a higher risk of iron deficiency due to heavy periods and may need to take iron in a supplement form. However, always speak to your GP or a registered dietitian before starting to take a supplement.
