01 Sep 5 Important (Science Nerd) things you should know about Iron
Iron is an essential mineral and forms a vital component of myoglobin and haemoglobin (myoglobin and haemoglobin are proteins that bind with oxygen to transport it around the body)
- Iron must come from a dietary source. Dietary iron comes in 2 forms:
- Heme Iron
Predominantly from red meat
Is referred to as Fe+++ in the science world
- Non-Heme Iron
Predominantly found in plant sources and iron salts, but also in meat
Is referred to as Fe++ in the science world
Not to geek out and get too nerdy, but Heme Iron is more easily absorbed then Non-Heme Iron. This is because Non-Heme Iron must be converted from Fe++ to Fe+++ in the body before it can be absorbed.
- Iron absorption can either be enhanced or inhibited.
Enhancers
Vitamin C
Organic Acids
Meat
Inhibitors
Zinc
Calcium
Phytates
Polyphenols
- You can suffer from both iron deficiency and iron overload:
Deficiencies May Result In:
- Anaemia (small and pale red blood cells)
- Behavioural abnormalities in kids
- Spoon shaped nails that curl upwards
Deficiencies are usually caused by:
- Plant based eaters may eat many Non-Heme Iron sources but their bodies may not convert efficiently and therefore they do not absorb as much as they need
- A deficiency in Vitamin A may intensify a deficiency in Iron
- Women require more iron during pregnancy or menstruation but they simply don’t eat enough or the right sources
- Iron dietary sources are under consumed overall
Overload’s May Result In:
- Vomiting
- Nausea
- Shock or even death
- Increased risk of Cardiovascular disease, Cancer, Neurodegenerative diseases
- Overloads are usually caused by:
- Taking too many vitamin pills
- Not enough physical activity
- Inefficiencies in body processes
- Sources of iron
- Organ Meats
- Fish
- Olives
- Potatoes
- Peppers
- Seaweed
- Brown Rice
- Dark leafy greens
- Beans
- Dried fruits like raisins and apricots
- Seeds like pumpkin seeds
- Prune Juice
If you feel as if you may have a health issue that is the result if an overload or deficiency then please seek the help of your primary health care provider.
