Iron Deficiency
Iron-rich Foods
Iron is a trace mineral required for red blood cell formation and adequate formation of hemoglobin (血色素)- the protein that carries oxygen in the blood and yoglobin(肌血球素), a similar protein that carries oxygen in the muscle tissue. Iron also plays a central role in many vital biochemical pathways and enzyme (酶)systems including those involved with energy metabolism(代谢), neurotransmitter production (serotonin (含于血液中的复合胺)and dopamine(多巴胺)), collagen formation and immune system function.
Iron
Iron deficiency is the most prevalent nutritional problem in the world. Two---thirds of children and women of childbearing age are estimated to suffer from iron deficiency and one---third are prone to disorders of iron deficiency--- like anemia. Female athletes, in particular, are at risk for IDNA because aerobic exercise may result in a significant depletion of body iron stores . It may negatively affect endurance performance and muscle fatigability(易疲劳性).
