Mental Fog & Fatigue: Am I Getting Enough Iron?

Sometimes I ask myself if I am getting enough iron when mental fog and fatigue wear me down. There are several conditions and ways that iron absorption is hindered in our bodies. Today, I’d like to cover a few of them and get to the root of preventing it for you and me. Sound good?

What Iron Does in The Body

Iron is an essential mineral in hemoglobin that carries oxygen from the lungs to the tissues via the red blood cells. It is also essential for muscle metabolism and connective tissue repair. Cellular synthesis, neurological function, physical growth, and hormones all need iron to function, too! (1)

Is it any wonder that we experience brain fog, fatigue, nervousness, poor exercise endurance when we don’t get enough iron? Iron deficiency anemia is common in underdeveloped countries, but with certain conditions it is here in the United Sates, too.

Hepcidin is a hormone that regulates the use of iron throughout the body and alters its use and absorption for various conditions like fighting infection, or chronic inflammatory states. (2) We will see iron come in two forms.

Two Types of Iron:

  1. Heme-Iron—is more bioavailable for the body to use and is found in lean meats like beef, poultry and fish.
  2. Nonheme Iron —comes from plants and iron fortified foods.

Who’s at Risk for Not Getting Enough Iron?

There are several people groups and physical conditions that interfere with iron absorption. One group is childbearing women, who’s monthly cycle and high demands on the body, use up iron stores in the cells. Growing children and adolescent are another group.

A third group are people facing chronic disease and have inflammation, celiac disease, malabsorption issues in the gut or inflammatory bowel disease, and people with long-term use of proton pump inhibitors. (3) When considering these conditions, it’s important to remember the underlying cause and effects:

  1. Chronic Inflammation stresses the body and puts a higher demand on all the cells, therefore requiring increase use of available nutrients. (2)
  2. Malabsorption issues are a result of damage to the intestinal lining or gut microbiome and the ability to store and use the iron in the red blood cells is hindered. (2)

Simple Ways to Get Enough Iron in the Body

There is always good news, my friend! God gives us everything we need to heal our bodies, reduce inflammation and provide the necessary resources to refuel and absorb our iron. Proverbs 1:5 says to let the wise hear and increase in learning and the one who understands obtain guidance.

It is imperative to know what God’s design for our bodies is and how the food He provides increases health and wellness! An anti-inflammatory diet containing berries, green leafy vegetables and bright orange vegetables, as well as vitamin C rich foods, is going to help decrease chronic inflammation.

Some of my butternut squash recipes, that are rich in vitamin A and beta-carotene, are here to help you with this process!

    and the one who understands obtain guidance

It is also good to understand how some common cultural habits may interfere with our iron absorption. Take for instance drinking tea or coffee with our meals. Both beverages are known to interfere with iron absorption. Oops! That’s one I am guilty of enjoying with my meals. Instead, I’ll be ordering more hot water with lemon or skipping a drink with my meal altogether!

A source from the University of Louisville says drinking milk interferes with iron absorption and others say it doesn’t. (1) With conflicting professional resources in reputable sites like the National Institute of Health, maybe it’s best to be cautious, just in case.

It’s interesting too, that phytates from grains and cereals are mentioned as interfering with iron absorption. Soaking beans and legumes can reduce this effect, while using sourdough breads and the milling and soaking process of breadmaking has a similar effect. The University of Louisville source also reports casein, whey, egg whites, and soy proteins inhibit iron absorption in people, so being aware of potential disruptors is a good idea. (3)

Bottom Line

Yearly exams and bloodwork will alert you and me to our iron levels, so it’s a good idea to stay on top of our levels. Being aware of what God provides in the garden to heal and sustain is a good idea, too! We don’t want too much iron, that can interfere with our heart and kidneys. But we do want the delicate balance designed by our Creator to stay put.

Friend, that means eating what He supplies in the garden to reduce inflammation and avoid these chronic conditions. That way we are getting enough iron and all the other vitamins and minerals we need to do the work He has called us to do.
