研究发现,微量元素硒对体外培养的肝癌细胞具有选择性杀伤和抑制作用,其对正常肝细胞却没有明显影响。显然补硒可成为人们预防肝癌、乙型肝炎的有效措施。据研究,人体存储硒的能力很弱,要经常食用含硒较高的食品,才能使机体获得足够的硒。蘑菇、大蒜等食品含硒较高,且易被人体吸收,所以,应多食用。此外,动物的肝、肾含硒量也高,可经常食用。
The study found that trace element selenium has a selective killing and inhibition of hepatoma cells cultured in vitro, which had no significant effect on normal liver cells. Apparently, selenium supplementation can be an effective measure to prevent liver cancer and hepatitis B. According to the study, the body’s ability to store selenium is very weak. It is necessary to regularly consume foods with high selenium content so that the body can get enough selenium. Mushrooms, garlic and other foods containing selenium higher, and easily absorbed by the body, so should eat more. In addition, animal liver, kidney selenium content is high, can be eaten regularly.
