Levels Of Dietary Iron In Adolescents Affects Structure Of Developing Brain

A lack of iron in the diet in the early years of life can affect the brain’s physical structure, according to a study by U.S. researchers who measured levels of a protein (transferrin) that transports iron throughout the body and the brain in adolescents. They found that transferrin levels were related to detectable differences in the brain’s macro-structure and micro-structure when the adolescents reached young adulthood. The researchers hope that their discovery may shed some light on the neural mechanisms by which iron affects, neurodevelopment and neurodegeneration.
