大多数人或许并不需要服用维生意丸来增强体质。但是,数以百万计的人却有必要服用。据报道,美国有40%的人服用维生意丸。 The American Medical Associations notedthat Vitamins can help keep people healthy whenused correctly. For example, children may need totake vitamins for a while; pregnant women andwomen breast-feeding[2] their children may needvitamins; people who do not eat meat or are eatingless food to lose weight[3] may need them. In general, other people do not. But they should try to eatmoderate amounts of all kinds of foods-fruits andvegetables, grains, milk products, and meat andfish. 美国医学协会指出,如果服用得当,维生意有助于人体健康。譬如,儿童可能需要服用一段时间的维生素丸;孕妇和哺乳期妇女可能需要服用;不食肉或节食减肥者也可能需要服用。一般说来,其余的人并非有此需要。不过,他们应尽量对各种各样的食品都适量地吃一点,诸如水果园蔬菜、谷物、乳制品。还有肉和鱼。 About half of all Americans who take vitaminsuse small amounts just to increase their vitaminlevels a little. The health care groups say thesepeople probably are not harming themselves. Theother half uses large amounts in an effort too[4] prevent some things as cancer and heart disease. 服用维生素丸的美国人中,约有半数的人只是少量服用,以略微提高体内的维生素水准。卫生保健组织称,这样可能不会危害健康。还有半数的人则大剂量地服用,目的在于预防癌症和心脏病等疾病。 AMA researcher Wayne Callaway says thatthere's no proof[5] that this works[6]. And hugeamounts of vitamins, he says, can be harmful. Forexample, too much vitamin A can damage the liverand bones; too much vitamin B can damage thenerves; too much vitamin C or vitamin D may produce kidney stones. Dr. Callaway notes that manypeople may not get all the vitamins health expertssay we need every day. But those daily levels, hesays, already are a little higher than we need forgood health. 美国医学协会的研究人员韦恩·卡拉韦认为,没有证据能表明此法灵验。他说,大量服用维生素可能有害无益。例如,过多的维生素A会损伤肝脏和 骨骼;过多的维生素B会损害神经;过多的维生素C或D可能导致肾结石;卡拉韦医生说,许多人可以不全部服用保健专家认为我们所需的维生素。但是,他说,那些日常定量已经略微超出人体健康所需的水准了。
