1.2. What Happens If We Lack Iron?

Iron deficiency can lead to a condition called iron deficiency anemia. Symptoms include:

Fatigue: Persistent tiredness and weakness.
Pale Skin: Reduced hemoglobin levels cause the skin to appear pale.
Shortness of Breath: Insufficient oxygen supply to the body.
Headaches and Dizziness: Reduced oxygen flow to the brain.
Brittle Nails and Hair Loss: Indicative of overall nutrient deficiency.

According to the World Health Organization, iron deficiency is one of the most common nutritional deficiencies worldwide, affecting over two billion people. Iron deficiency anemia can impair physical and cognitive development, especially in children and pregnant women. Ensuring adequate iron intake is, therefore, crucial for maintaining optimal health and preventing these complications.

2. How Much Iron Is Typically Found In Chicken?

The iron content in chicken varies depending on the cut. Different parts of the chicken, such as breast, thigh, and liver, contain different amounts of iron.

2.1. Iron Content In Chicken Breast

Chicken breast is a popular choice for its lean protein content. However, it contains a relatively low amount of iron compared to other cuts.

Iron Content: A 3.5-ounce (100-gram) serving of cooked chicken breast contains approximately 0.7 mg of iron.
Significance: While chicken breast is a good source of protein, it is not a significant source of iron.
Comparison: This amount is less than 5% of the Recommended Daily Allowance (RDA) for iron, which ranges from 8 mg for adult men to 18 mg for adult women.

2.2. Iron Content In Chicken Thigh

Chicken thigh, which is dark meat, contains more iron than chicken breast.

Iron Content: A 3.5-ounce (100-gram) serving of cooked chicken thigh contains approximately 1.3 mg of iron.
Significance: Chicken thighs provide a slightly better source of iron compared to chicken breast.
Comparison: This amount is about 7% of the RDA for iron.

2.3. Iron Content In Chicken Liver

Chicken liver is a nutritional powerhouse, rich in many vitamins and minerals, including iron.
