Iron - Function Iron is a vital mineral, needed for: Growth
Haemoglobin Energy metabolism Brain development Immune system Internal heat regulating system Growth, particularly muscle Making haemoglobin, a vital protein for red blood cells, needed to carry oxygen around the body Energy metabolism Brain development Part of the immune system, helping to fight infections Part of our internal heat regulating system

Iron - Absorption Iron absorption inhibitors:
Tannins Oxalates Polyphenols Phytates Egg & pulse proteins Calcium Copper Manganese Iron absorption enhancers: Vitamin C Fructose Sorbitol Alcohol Diet Duodenum Transported in the blood Muscle Liver Spleen Bone Marrow Haemoglobin (60%) Myoglobin Enzymes Storage Excretion Absorption =1mg iron per day (about 10%) In Haemochromatosis, absorption = 2-4mg per day
5
Dietary Iron In the UK the main sources are from meat, meat based food, cereal and cereal products and vegetables. Iron is found in food in two forms, haem and non-haem. Our body finds haem iron easier to absorb that non- haem sources of iron. Rate of iron absorption from red meat = 20 – 30% Absorption from vegetable and grains = 1 – 20%

Types of iron Haem Iron sources Non Haem Iron sources Red meat Turkey
Chicken Offal Seafood Fish – particularly oily fish Fortified breakfast cereals Eggs Pulses and beans Nuts & seeds Brown rice Tofu Bread – particular wholemeal Green leafy vegetable Dried fruit Dark chocolate & coco powder

Dietary Advice Do not be overly restrictive reducing your iron intake, consider a small reduction in haem sources and fortified foods Avoid multivitamins containing iron Avoid multivitamins containing vitamin C, particularly at mealtimes Avoid raw shellfish Reduce your absorption of iron by eating more: Tea or coffee with meals Eggs and pulses Foods rich in Calcium, Oxalates, Polyphenols and Phytates Reduce your absorption of iron by eating less: Sugary foods Saturated (animal) fats Fruit and juices with meals Alcohol
