含硒丰富的食物有 含硒高的食物有哪些，人体每天需要多少硒 硒是人体内最重要的微量元素之一，现在人们已经越来越意识到硒对人体健康的重要性，于是人们会很急于补硒。含硒高的食物其实有很多，但是人体每天却不需要太多的硒元素。 科学家认为，人体每天需要50 mg,250 mg硒。 人体缺硒，就容易患克山病、大骨节病、胃癌等。硒还具有减弱黄曲霉素引发肝癌的作用，抑制乳腺癌的发生等作用。因此，必须注意摄取含硒的食物。 专家评出富含硒食物排行榜 富含硒的食物有鱼、虾、乳类、动物肝脏、肉类、坚果类(如花生、瓜子)等。 黄油、鱼粉、龙虾、蘑菇、猪肾、大蒜等食物虽然含有一定的硒元素，但吸收率不太理想。营养学家提倡补充有机硒，如硒酸酯多糖、硒酵母、硒蛋、富硒蘑菇、富硒麦芽、富硒天麻、富硒茶 含硒高的食物有龙虾、鱼及一些甲壳类水产品。其次是动物的心、肝、肾等脏器。蔬菜中如荠菜、芦笋、豌豆、大白菜、南瓜、洋葱、番茄等也含一定量的硒。谷物的糠皮中也含有少量硒。在含硒的食物中蛋类含硒量多于肉类，每100 克食物中，猪肉fertility better.
