铁是人体内生命活动不可缺少的微量元素之一。人体内的铁含量甚微,总量只有3.0～4.5g。体内缺铁会使血红蛋白的合成减少,发生缺铁性贫血。然而,科学家们最新研究发现,体内缺铁还会导致胃癌。这是因为铁的缺乏,导致慢性萎缩性胃炎,而使胃酸过低或缺乏,使细菌在胃内聚集、聚殖,这

However, scientists recently discovered that iron deficiency in the body can also cause stomach cancer. This is because the lack of iron leads to chronic atrophic gastritis, which causes the stomach acid to be too low or lacking, causing the bacteria to accumulate in the stomach and accumulate.
