Muhammad Yousaf: Iron Deficiency Beyond Diet

Muhammad Yousaf, Iron Deficiency Beyond Diet, shared a post on LinkedIn:

“When we hear the words ‘iron deficiency,’ the first thing that often comes to mind is, ‘Maybe the person is not eating enough iron.’

But during my studies, I learned that iron deficiency is more complex than simply looking at how much iron someone eats.

Iron is an essential mineral. It plays an important role in hemoglobin, the protein in red blood cells that carries oxygen throughout the body.

Iron is also involved in growth, neurological development, and normal cellular function.

So, why can iron deficiency happen?

There are several possible reasons.

1. Not enough iron in the diet

A diet with limited sources of iron can increase the risk of deficiency. Iron comes in two main forms:

Heme iron found mainly in meat, poultry, and seafood

Non heme iron found in foods such as beans, lentils, nuts, seeds, vegetables, and fortified foods

But the story doesn’t end with food intake.

2. Poor absorption

The amount of iron present in food is not necessarily the same amount that the body absorbs.

Vitamin C can improve the absorption of non-heme iron, while some compounds in foods, such as phytates and certain polyphenols, can reduce its bioavailability.

This made me realize an important point: Nutrition is not only about what is present in food but also about what the body can absorb and use.

3. Increased requirements

Some stages of life require more iron. For example, growing children and pregnant women have increased requirements and can be more vulnerable to iron deficiency.

4. Blood loss and health conditions

Iron deficiency can also be related to blood loss or conditions that affect absorption.

Menstrual blood loss, gastrointestinal blood loss, infections, inflammation, and some chronic conditions can contribute to anemia or iron deficiency.

What about iron deficiency anemia?

This is another area where I learned that we should be careful with terminology. Iron deficiency and anemia are not exactly the same thing.

Anemia means that the hemoglobin concentration or number of red blood cells is lower than normal.

Iron deficiency is considered the most common nutritional cause of anemia, but anemia can also have other causes, including folate or vitamin B12 deficiency, infections, inflammation, chronic disease, and inherited blood disorders.

So we shouldn’t automatically assume: ‘Anaemia is equal iron deficiency.’

The underlying cause needs to be assessed.

Imagine someone eats lentils regularly.

Lentils provide non heme iron, but the amount absorbed by the body depends on several factors.

Combining iron containing plant foods with a source of vitamin C, such as tomatoes, citrus fruits or other vitamin C rich foods, can help improve non heme iron absorption.

This is why food combinations and overall dietary patterns matter not just individual nutrients.

What I learned from this

Iron nutrition made me understand something important:

A nutrient deficiency is not always simply a matter of ‘not eating enough.’

We need to think about:

Intake, Absorption, Requirements,  Losses,  Health conditions

This is also why nutrition assessment should look at the whole person, rather than focusing on one food or one nutrient.

What do you think is most often overlooked when we talk about iron deficiency: dietary intake, absorption, increased requirements, or blood loss?”
