Dietary Availability of Iron in Milligrams Per Person Per Day
Iron is a vital nutrient for human health, playing a key role in oxygen transport and energy production. The availability of dietary iron varies significantly across countries, reflecting differences in diets and access to iron-rich foods.
Which country has the highest dietary iron availability?
Ethiopia leads globally with a remarkable dietary iron availability of 45.4 mg per person per day, significantly higher than other countries due to the consumption of iron-rich traditional foods.
Top countries by dietary iron availability
1. Ethiopia: 45.4 mg
2. Malawi: 21.8 mg
3. Paraguay: 21.0 mg
4. Philippines: 20.8 mg
5. Sri Lanka: 19.7 mg
How does dietary iron availability vary globally?
African and Asian nations like Ethiopia and Malawi rank highest, reflecting diets centered on iron-rich staples. In contrast, many European and Western nations have moderate to low levels due to differences in dietary patterns and food fortification practices.
Why is iron availability important for health?
Iron deficiency is a common nutritional issue worldwide, leading to anemia and reduced cognitive and physical performance. Countries with higher iron availability typically have better public health outcomes related to iron deficiency.
How do developed countries rank in iron availability?
Developed nations like the United States (13.9 mg) and Canada (12.4 mg) rank moderately due to diverse diets and fortified foods, ensuring adequate iron intake despite lower natural dietary sources.
Which regions have the lowest dietary iron availability?
Countries like the Dominican Republic (4.8 mg) and Ecuador (4.9 mg) have the lowest dietary iron availability, often reflecting limited access to iron-rich foods and dietary diversity.
How does dietary iron availability influence public health?
Regions with low iron availability face higher rates of anemia and related health issues. Improving access to iron-rich foods and fortifying diets are essential strategies for combating iron deficiency.
Global trends in dietary iron availability
While African countries dominate the top rankings, reflecting reliance on iron-rich grains and legumes, many Western countries rely on fortified foods to meet iron requirements. Emerging economies are bridging the gap through improved agricultural and nutritional strategies.
