Iron also helps regulate body temperature, supports immune function, and is necessary for the production of certain hormones.
Iron deficiency is a common nutritional disorder that affects millions of people worldwide. It can lead to fatigue, weakness, and impaired cognitive function. In severe cases, iron deficiency can cause anemia, a condition characterized by a lack of red blood cells or hemoglobin in the blood.
Iron Sources and Recommended Daily Intake
There are two types of iron: heme iron and non-heme iron. Heme iron is found in animal-based foods, such as meat, poultry, and fish, while non-heme iron is found in plant-based foods, such as beans, lentils, and fortified cereals.
The recommended daily intake of iron varies based on age, sex, and other factors. The National Institutes of Health (NIH) recommends the following daily intake of iron:
| Age | Recommended Daily Intake |
| — | — |
| Infants 6-12 months | 11 mg |
| Children 1-3 years | 7 mg |
| Children 4-8 years | 10 mg |
| Males 9-13 years | 8 mg |
| Males 14-18 years | 11 mg |
| Males 19-50 years | 8 mg |
| Females 9-13 years | 8 mg |
