Iron deficiency is the most common nutritional deficiency worldwide. Now, there are different levels of deficiency. You could lack iron a little bit, which means you may not have a lot of stamina in the gym, may be unusually fatigued, and you may every cold that goes by. This is because iron is needed for many functions in the body. If you are severely deficient, it is called anemia. There are different forms of anemia but this one is called iron deficiency anemia and it is the most common type of anemia. It is a condition in which your blood lacks healthy red blood cells, which is a problem because they carry oxygen throughout your body.

Without enough iron, your body cannot product enough of a substance in the red blood cells that enables them to carry oxygen, which is called hemoglobin. Hemoglobin is the red substance inside your blood cell and it is centered on iron. Now, your heart is pumping blood passed your lungs 80 times per minute, or once every three quarters of a second. In this short time period, the hemoglobin must be capable of snapping up the iron in the lungs and distributing it throughout the body. It is iron that gives hemoglobin that quality.

Symptoms of an Iron Deficiency

If you have iron deficiency anemia, you have a lot of symptoms. Just lacking iron in general makes you tired but this deficiency includes symptoms like:

  • extreme fatigue
  • shortness of breath
  • weakness
  • no stamina
  • light headedness
  • dizziness
  • cold hands and feet
  • poor appetite
  • brittle nails
  • restless leg syndrome
  • swollen and sore tongue
  • unusual cravings of things that lack nutrition like ice, dirt or starch

Many of us just lack a bit of iron; not anywhere near the level that you would classify as anemia. But lacking iron can impacts your overall health, including your immune system and your energy. You may also have pale lackluster skin and lips.

Over 12 million Americans develop iron deficiency anemia, which leads to about 778,000 trips to the emergency room and over 5,300 deaths each year in the U.S. alone.

Common Causes of Anemia

The most common cause of iron deficiency anemia is simply a lack of iron in your diet. This is a severe lack of iron, not just a small amount. Any digestive tract issue that impacts iron absorption or the absorption of nutrients like in celiac (issues with gluten) or Crohn’s disease, issues with bleeding. Obesity interferes with iron absorption. The regulator of iron absorption and iron release from the body in the liver is effected by obesity and it blocks you from absorbing iron. Gastric bypass surgery for weight loss also impacts iron absorption rates. When you are pregnant and “eating for two”, that can lead to anemia.

But low iron does not necessary cause anemia. This is common in vegetarians and vegans, as they do not suffer from anemia. Especially because iron is found in greens and dark leafy vegetables like spinach, dried fruit like raisins and apricots, and in fortified cereals, breads and pastas. The problem is that, in this case, it is not heme iron. Heme iron is found in red meat mostly, but also fish and poultry. This is a lot easier to absorb than the iron found in vegetables.

Vegans may need an iron supplement, along with some folate, Vitamin B12 and the amino acid Taurine, as these nutrients are needed to create red blood cells. All of these nutrients are commonly lacking in a vegan diet.

Combatting Iron Deficiency

The good news is that you can usually correct iron deficiency with a superior iron supplement. But sometimes additional tests are needed to determine iron deficiency anemia, especially if your doctor suspects you are bleeding internally. Once you have anemia, it takes about a good solid year to replete the iron stores in your body.

Vitamin C has been shown to enhance the absorption if iron in your body. There are things in foods that block the absorption of iron. What Vitamin C does, is converts the iron from your food to a form that is very absorbable, called feris iron. There are other things in food like citrus, malic and lactic acid that enhance the absorption of non-heme iron. Non-heme iron is the iron that is not found in meat or fish. But, oddly, consuming meat, poultry and fish along with your iron supplement or along with the vegetables that contain iron, improves the absorption of iron.

Phytic acid is found in legumes like beans and lentils, wheat, nuts and seeds. This acid seems to bind to the iron to prevent its absorption. Just a small amount of phytic acid in your food can reduce the absorption of iron by about 50%. So the absorption of iron from foods like beans and lentils has been shown to be as low as 2% because of the phytate content. But the way you prepare the food helps degrade this.

Polyphenols in coffee and tea can really inhibit the absorption of non-heme iron. But if you have some Vitamin C, it will help block that affect and will absorb the iron better. Soy protein – different than the phytates found in the soy bean – has been found to inhibit the absorption of iron, this includes tofu. Calcium seems to do this, as well as the minerals Zinc and Magnesium. So always take your iron separate from these products.
