The Irony of Iron:  We know we need it, but why?

Ask anyone, and they can probably tell you that Iron is an important mineral.  Sadly, many people aren’t too sure why we need it or how to get more of it. We're here to break it down so you can not only explain what iron is, why we need it, and what happens when you’re Iron deficient; but also pinpoint specific foods and recipes to increase the amount of iron in your diet!  

Iron is a mineral that is used to create hemoglobin, the substance in red blood cells that carries and delivers oxygen to other parts of the body so that cells can produce energy. Iron also helps to remove carbon dioxide. Iron deficiency is one of the most common nutritional deficiencies that occur. Iron deficiency anemia occurs when the body’s iron stores are so low that not enough normal red blood cells can be made to carry oxygen efficiently.

The biggest thing to remember here is that a person can have an iron deficiency without having anemia.  An iron deficiency diagnosis can be made when a person has both low hemoglobin (the iron-containing protein in our blood that carries iron and oxygen to cells) and hematocrit (percentage of red blood cells in the blood) and low serum ferritin (amount of iron stored in the body). Serum iron and transferrin-iron saturation percentage will be low with iron deficiency as well. Iron deficiency without anemia occurs when a person has low serum ferritin and/or transferrin saturation but normal hemoglobin levels; when both levels are low, a person has iron deficiency anemia.

Fatigue, weakness, difficulty maintaining body temperature, headaches and dizziness often occur with low levels of iron. For obvious reasons, none of this sounds fun! To avoid iron deficiency, it pays off to consume enough iron in your diet.

There are two types of iron -

  • Heme is the type of iron that comes from an animal source like turkey, beef and clams.
  • Non-heme iron can be obtained through plants.

Although heme iron is easier for your body to absorb, non-heme iron can get the job done just as well if focused on daily. A helpful tip is to consume a source of vitamin C along with your non-heme iron rich foods to enhance absorption. Some of our favorite sources of plant based iron are beans, lentils, tofu, cashews and dark leafy green vegetables (think spinach and kale).
