How Much Iron Do You Need?

The body recycles iron and is thus conserved. Thus, repurposing iron from red blood cells and old proteins supplies the body with a generous amount. However, we still need a significant amount from the diet.

Our satiety analysis reveals that your body craves at least 12.5 mg of iron per 2000 calories.  However, achieving the Optimal Nutrient Intake of 25 mg per 2000 calories from food aligns with an 18% reduction in energy intake.

What Does Iron Do for the Body?

Iron is an essential mineral that your body needs in small amounts.  Although we don’t need much of it, it has several key bodily roles.

Iron is an essential component of haemoglobin, the substance in red blood cells that carries oxygen from your lungs to the rest of your body.  Haemoglobin makes up about two-thirds of your body’s iron stores.

If you don’t have enough iron, your body can’t make enough oxygen-carrying red blood cells.  This means your tissues and muscles won’t get enough oxygen to function optimally. 

Iron and iodine are required to make thyroid-stimulating hormone (TSH).  Thus, inadequate iron can cause hypothyroidism. 

Iron is critical to the formation of many proteins (e.g., haemoglobin, myoglobin, neuroglobin) and enzymes (e.g., cytochromes and peroxidases) in the body that regulate various functions.

We require iron for the synthesis and repair of DNA.

Iron is an antioxidant that protects against damaging substances like heavy metals.  However, when you have excess iron, it can become an oxidant or a damaging substance in and of itself.

Iron helps regulate cognition and behaviour and has been shown to play a role in attention and concentration.

Iron is vital for creating energy and transporting electrons through the electron transport chain.

Iron is also critical to maintaining strong bones, detoxifying, regulating immune function, skin and nail formation, and synthesising neurotransmitters in your brain. 

Heme Iron vs Non-Heme Iron

There are two forms of iron found in foods: non-heme iron, which is found in plant and animal foods, and heme iron, which is found exclusively in animal foods.

Animal foods containing heme iron have a higher bioavailability and are absorbed more readily, as they do not require cofactors that enhance uptake.  Approximately 15-35% of heme iron sources are absorbed.

On the other hand, non-heme iron is less bioavailable and requires different nutrients to ensure absorption.  As a result, only around 2% of non-heme iron is absorbed.  Hence, you may be at risk of anaemia if you are a strict vegan

However, while some people make a big deal of the bioavailability of iron in plants vs. animal products, super-high iron absorption is not necessarily a good thing either.

If you consume an omnivorous diet, you are unlikely to have significant issues with low iron levels unless you have digestive problems, consume a lot of grains, or consume minimal amounts of vitamin C.

Factors That Increase Iron Absorption

Your gut will absorb more iron in your intestines if you need more of it.  On the contrary, your body will let it pass through if you have adequate amounts in your system. 

Certain compounds in other foods act as ‘enhancers’ of absorption to increase the bioavailability of non-heme iron.

Vitamin C, fructose, and sodium increase the absorption of dietary iron.  Therefore, if you are getting less vitamin C, sodium, or fructose, you may not absorb as much iron as you would.  Iron supplements often include vitamin C for this reason.

MFP Factor is a peptide found in meat, fish, and poultry.  It has been shown to increase the absorption of non-heme iron by almost threefold.

Factors That Decrease Iron Absorption

Phytates are plant compounds found in grains, vegetable protein, legumes, and green leafy vegetables known as ‘antinutrients’. They decrease the absorption of iron.

Similarly, plant compounds like lectins and polyphenols like tannins inhibit iron uptake in the body’s digestive tract. 

Oxalate, or oxalic acid, decreases iron absorption from non-heme foods. Many plant foods, such as kale and spinach, are high in oxalate and iron.

Consuming large amounts of calcium and (or) copper in the diet alongside iron-rich foods decreases iron absorption.

Factors That Increase Iron Demand

You may need more iron in your diet if you:

If you are female and have low energy levels, check for low ferritin levels on your standard blood tests. 

Practical steps you can take to increase your iron levels include:

  • modifying your diet to improve your iron intake,
  • taking iron supplements,
  • minimising calcium and copper intake around high-iron foods,
  • consume more heme iron vs non-heme,
  • ensuring you are getting adequate vitamin C (which assists iron absorption), and
  • reducing phytates, oxalates, and lectins (e.g., grains and legumes). 

Can You Get Too Much Iron?

Iron is one nutrient that menstruating women require significantly more of.  However, men who tend not to bleed as frequently in the modern day are more prone to accumulating excessive amounts of iron.  This condition is known as haemochromatosis or iron overload, affecting around one in three hundred people. 

While adequate iron helps manage oxidation, excess iron can bind to proteins and act as a pro-oxidant, causing tissues to oxidise (or rust).

If left untreated, the excess iron can increase your risk of diabetes, liver cirrhosis, heart disease, neurodegeneration, and a host of other chronic diseases. 

Symptoms of Iron Overload

Symptoms of iron overload include:

Although men seem to have a greater risk of developing haemochromatosis, you should watch for elevated ferritin levels, regardless of whether you are male or female.  If they are high, consider regular blood donations.  Blood donation is not just good for you.  It could be a matter of life or death for someone in need. 

What Foods to Avoid if You Have Hemochromatosis

  • Iron toxicity and its symptoms can be improved by ensuring a nutrient-dense diet, particularly adequate niacin, tryptophan, zinc, manganese, copper, and lipoic acid.
  • Decrease your intake of high-iron foods like red meat and organ meat to support your body against hemochromatosis.
  • Avoiding the consumption of vitamin C alongside iron-rich meals can decrease the amount of iron you absorb.
  • Reducing your intake of bread, cakes, cereals, and cookies fortified with iron can remove considerable iron from the diet.

If you have high ferritin levels, you can flag this in your settings, Nutrient Optimiser, to de-emphasise dietary iron. However, it can be challenging to significantly reduce iron in your diet without compromising many other nutrients, so you should only de-prioritise a nutrient if your test results show high levels. 

In the Micros Masterclass, we use Nutrient Optimiser to prioritise foods and meals that contain your priority nutrients.  So, if you already get plenty of iron, the foods and meals prioritised for you will contain less iron.   

What Foods to Eat if You Have Hemochromatosis

While ‘antinutrients’ are often seen as ‘bad’ for health, this is where incorporating more oxalate, lectin, and phytate-containing foods (if you tolerate them) can be helpful to manage hemochromatosis as they are known to inhibit iron absorption.

  • Consuming foods higher in calcium and copper can also help decrease iron levels and its uptake.
  • Coffee and tea contain tannins, which help inhibit iron absorption.
  • Consuming more fish, white meat (as in chicken), and plant proteins can decrease your dietary iron while supplying you with ample, bioavailable protein.
  • Egg proteins are known to inhibit iron absorption, which can be helpful for people looking to reduce their iron levels.
  • Because the liver is in charge of recycling this micromineral, supporting the liver is often essential to regulating iron stores.  So, working to have great overall health and excellent liver function is crucial to ensuring your body can get rid of the iron it doesn’t require.

Zinc:Iron ratio

Excess iron intake can affect zinc absorption.  If your dietary ratio of iron:zinc is greater than 2:1, your zinc absorption will be reduced.  For this reason, prioritise foods with favourable zinc: iron ratios or ensure sufficient zinc intake.  This is especially important for vegans and vegetarians. 

Iron Fortification

Because we crave iron in food, consuming high amounts of food products fortified with iron but otherwise nutrient-poor with a low satiety value (like flours and breakfast cereals) may lead to overconsuming these foods. 

Furthermore, we may also see a lack of cravings for foods that naturally contain iron, like meat and vegetables.  Therefore, if you are suffering from haemochromatosis, your first step should be to avoid foods fortified with iron. 

Availability of Iron in the Food System

As shown in the chart below, dietary iron availability increased with the introduction of iron-enriched foods like breakfast cereals to combat anaemia in the 1940s. 

Ironically, iron absorption is also negatively affected by phytates in the grains that cereals are made from.  In addition, the form of iron used in fortification is also not ideal.  It is known to cause constipation, feed pathogenic gut flora, and contribute to oxidative stress that damages the intestines.

So, if you are worried about your iron intake and the ferritin levels in your blood, be sure to avoid processed foods fortified with iron (e.g., breakfast cereals, pasta and rice) as your highest priority.
