胆固醇历来被认为是造成心脏血管疾病的物质。近年来,国外的医学家们却提出了不同的看法,认为血液中正常的胆固醇含量具有一定的抗癌功能。美国、瑞士的科学家在实验中发现,人体血液的白血球中,有一种称为“噬异变细胞白血球”。这种白血球能辨别出异变细胞和癌细胞,它分泌出一种“抗异变素”来杀伤和吞噬异变癌细胞,从而使癌细胞失去活力。血液中的胆固醇是维持“噬异变细胞白血球”生存必不可少的物质。如果血液中胆固醇含量过低, Cholesterol has long been considered as a cause of cardiovascular disease. In recent years, foreign medical scientists have put forward different views, that the normal blood cholesterol levels have some anti-cancer function. In the experiments, scientists from the United States and Switzerland found that one of the white blood cells of human blood is called “phagocytic leukocyte”. This white blood cell can distinguish between abnormal cells and cancer cells, it secrete an “anti-isoforms” to kill and swallow the cancer cells, so that cancer cells lose their vitality. Cholesterol in the blood is essential for maintaining the survival of “phagocytic leukocytes.” If the blood cholesterol levels are too low,
