In a new study this week, researchers have found evidence that iron deficiency is 'a widespread, underrecognized public health problem.'
An upsetting number of Americans have an iron problem, it turns out. New research this week reveals that about one in three people have some sort of iron deficiency.. Iron is key to many bodily functions, particularly the production of red blood cells, so being low in iron can be bad for our overall health.
Overall, about 14% of people were estimated to have absolute iron deficiency and another 15% had functional iron deficiency. Iron deficiency is often tied to and can cause anemia, defined as not having enough healthy red blood cells or hemoglobin, the protein that transfers oxygen from red blood cells to the rest of the body . However, the researchers found that the condition was still relatively common even in people without anemia or other relevant health issues.
The researchers say that more work needs to be done to understand the risk factors behind iron deficiency . We’re also still not sure exactly how functional iron deficiency can affect our health for the worse. But given their findings, they argue that current screening recommendations for low iron, which tend to focus on people at higher risk of iron deficiency, may need to be revised.
