吸烟者血清中抗坏血酸水平降低,维生素C缺乏的危险性增加,这只能部分地用他们的维生素C摄入量较低来解释。国家科学研究委员会食物与营养委员会最近将吸烟者维生素C的推荐膳食供给量(RDA)从60mg提高到100mg,但是还不能确定100mg实际上是不是最合适的摄入水平。为了更好地了解吸烟者究竟需要多少抗坏血酸,威斯康星医学院的研究者从1976～1980年第二届全
The smoker’s serum ascorbate levels are reduced and the risk of vitamin C deficiency is increased, which can only partly be explained by their lower vitamin C intake. The National Council for Science’s Committee on Food and Nutrition recently increased the recommended dietary vitamin C (RDA) intake for smokers from 60 to 100 mg, but it is not yet certain whether 100 mg is actually the most appropriate level of intake. To better understand exactly how much asbestos is needed for smokers, Wisconsin researchers from the second full year 1976-1980
