The best source of iron
If you’ve been told you’re not getting enough iron, you’re not alone. Iron deficiency is the most common nutritional deficiency globally — especially among children and pregnant women — and the only nutrient deficiency that is widely prevalent in developed countries, according to the World Health Organization.
That’s a problem because iron plays a number of critical roles in the body.
Heme vs. Non-Heme Iron: What’s the Difference?
There are two types of iron: heme iron from animal sources and non-heme iron from plant sources. Heme iron is more easily absorbed by the body than plant-based non-heme iron however heme iron may have some damaging effects on your body, that you should be aware of.
Heme Iron – Risks
High heme intake is associated with an increased risk of several cancers, including colorectal cancer, pancreatic cancer and lung cancer. Likewise, the evidence for increased risks of type-2 diabetes and coronary heart disease associated with high heme intake is compelling.
Too much iron can be a problem
When the source is Heme Iron from animal sources … too much iron can be absorbed leading to high iron stores. This can be checked on a blood test as High Ferritin … reflective of iron stores.
Studies show high stored iron concentration, as assessed by serum ferritin, was associated with the increased risk of Coronary Artery Disease.
