Iron-Rich Foods Boost Immune System, Fight Colds

Consuming a diet rich in iron, including foods like steak, poultry, spinach, lentils, and nuts, may help individuals recover more quickly from common infections. Research published in the Journal of Immunology indicates that iron deficiency compromises the function of crucial immune cells in the lungs, leading to a weaker defense against viruses.

Scientists observed that when mice had insufficient iron, their T-cells failed to produce interferon gamma, a protein essential for a strong antiviral response. This suggests that ensuring adequate iron intake before a viral infection can prepare the immune system for battle, potentially bolstering overall protection.

This discovery emerges as the UK's National Health Service prepares for a potentially harsh flu season, with a notable increase in hospital admissions compared to the previous year. Iron deficiency is a concern for a significant portion of the UK population, affecting approximately eight percent of women and three percent of men.
