Common Questions About Iron

What is iron?

Iron is a mineral essential for various biological processes in our body, such as formation of red blood cells and the transport of oxygen throughout the body. In our diet it exists in two primary forms: heme and non-heme iron. Heme iron is derived from animal products like red meat, poultry, and fish. This form is readily absorbed by the body. Non-heme iron, on the other hand, is found in plant-based foods such as beans, lentils, spinach, and fortified cereals. This form is not as easily absorbed and its uptake can be influenced by other dietary factors.

What does iron do for the body?

Iron is essential for the formation of hemoglobin, a protein in red blood cells that carries oxygen from the lungs to the rest of the body, where it is used by cells for energy production. Iron is also vital for immune function, cognitive development, and various other bodily functions.

How much iron do I need?

The recommended daily allowance (RDA) for iron varies based on age and gender. The recommendations also vary between countries. For adult males and post-menopausal females the RDA is around 8 milligrams per day. For pre-menopausal females, the RDA is higher: around 18 milligrams per day. Pregnant women might have an even higher RDA. It's important to meet your specific iron needs through a balanced diet with iron-rich foods.

What are the health risks associated with iron deficiency?

Iron deficiency can lead to anemia, causing symptoms such as fatigue, weakness, pale skin, shortness of breath, and dizziness. It can also impact cognitive function, immune function, and physical growth in children. Severe iron deficiency may lead to complications such as heart problems and pregnancy complications.

Can Iron be harmful?

Yes, excessive intake of iron (mainly due to supplementation) can be harmful to the body. Consuming too much iron can lead to iron toxicity, which can cause symptoms such as nausea, vomiting, abdominal pain, and in severe cases, organ damage. Thus, it's important to consult with a healthcare professional before taking iron supplements.

What if your iron is low?

If your iron is low, it can lead to symptoms such as fatigue, weakness, and difficulty concentrating. It's important to consult a healthcare professional to determine the cause of low iron and to discuss potential treatment options, which may include dietary changes, iron supplements, or other interventions.

How do vegans get their iron intake?

Vegans can get their iron intake from plant-based sources such as legumes (lentils, beans, chickpeas), tofu, tempeh, fortified cereals, quinoa, nuts, seeds, and dark leafy greens (spinach, kale, Swiss chard). Consuming vitamin C-rich foods alongside these iron sources can enhance the absorption of non-heme iron found in plant-based foods.
