Iron
Iron is an essential mineral vital for producing hemoglobin, the protein in red blood cells that transports oxygen throughout the body. It plays a key role in energy production, cognitive function, and supporting a healthy immune system. Iron is commonly found in red meat, beans, fortified cereals, and leafy greens. Many people, especially women and vegetarians, may require supplements to maintain adequate levels. Iron deficiency can cause fatigue and reduce immune strength.
Description
Individuals showing symptoms of anemia, such as fatigue, weakness, and pale skin, would benefit from testing their iron levels. This is particularly important for pregnant women, menstruating women, frequent blood donors, vegetarians, and people with gastrointestinal disorders that affect nutrient absorption.
Symptoms of Low Iron:
- Fatigue and weakness
- Pale skin and gums
- Shortness of breath
- Dizziness or lightheadedness
- Cold hands and feet
- Brittle nails
- Headaches
Symptoms of High Iron:
- Joint pain
- Abdominal pain
- Fatigue and weakness
- Liver damage, indicated by a swollen liver or jaundice
- Diabetes symptoms
- Skin that appears bronze or gray
- Irregular heart rhythms or heart palpitations
- Hormonal imbalances
Foods high in iron include red meat, poultry, and fish, which are sources of heme iron, more easily absorbed by the body. Plant-based sources of non-heme iron include lentils, beans, tofu, fortified cereals, dark leafy greens like spinach, and dried fruits like raisins and apricots. Pairing these with vitamin C-rich foods can enhance iron absorption.
Iron supplementation can effectively treat iron deficiency anemia, improving energy levels, cognitive function, and overall well-being. However, excessive iron intake can lead to iron overload, causing symptoms like liver damage, heart problems, and diabetes.
