Anna Wegel: 我注意到当我有小伤口时,会不自觉地想把手指放进嘴里,并且尝到一种强烈的金属味道。我很好奇为什么血液会有这种味道,以及为什么人体不是磁性的。 Courtney Jordan Beckler: 血液尝起来有金属味,主要是因为血液中富含铁。铁对于我们的身体至关重要,它是血红蛋白的重要组成部分,血红蛋白负责将氧气输送到全身。虽然铁对身体很重要,但我们体内铁的含量非常少,平均成人体内只有大约2.5克的铁,这不足以使我们具有磁性。如果医生告诉你缺铁,你可以通过食用红肉、家禽、豆类、深绿色蔬菜、干果和强化谷物等食物来补充铁。

Cardiologist Dr. Courtney Jordan Baechler helps us figure out the answer to two questions – why does blood taste like metal, and why are we not magnetic? And as a bonus, Dr. B. includes a super fun experiment that you can do at home.
