两次荣获诺尔奖的美国医学博士波林写了一本《感冒药可以休矣》(又名)《再见吧,感冒药!》的书,引起一场世界性的维生素 C 大论战。其结果,维生素 C 防治感冒的作用得到确认,还发现不少新的药理作用。波林博士在其著作中引用的这样一些实验材料:1970年冬,爱尔兰的一所女子学校对103名学生进行了三个月的实验观察,让57人每天服200毫克维生素 C,46人服安慰剂作对照。结果,感冒痊愈所需要的时间为,服维生素 C 组8天感冒痊愈,而服安慰剂组14天后才痊愈。另外,测定1亿个白血球周围维生素 C 的浓度发现,服维生素 C 者为60微克,服安慰剂者为43微克。波林博士认为,预防感冒所需维生素 C 的量,因人而异,最低是250毫克,最高是10克。在这个实验中,维生素 C 的供给量比波林博士规定的量低。因此,如不能从饮食中摄取50毫克以上维生素 C 的话,则无法期望达到预防感冒的效果。这说明饮食中维生 C 的含量是不可忽视的。1961年,他在瑞士对279名滑雪运动员进行了另一试验。一组每天服 The two Nobel Prize-winning American physician Pauling wrote a book titled “Cold Medicine Can Take Away” (aka “Goodbye, Cold Medicine!”), Provoking a worldwide controversy over Vitamin C. As a result, the role of vitamin C in preventing and treating cold has been confirmed, and many new pharmacological effects have also been found. Some of the experimental materials quoted by Dr. Pauling in his book: In the winter of 1970, a woman school in Ireland conducted a three-month experimental observation of 103 students, giving 57 people a daily dose of 200 mg of vitamin C and 46 serving Placebo as a control. As a result, the time needed for the recovery of a cold was as follows: The vitamin C group recovered in a cold for 8 days and was relieved 14 days after taking the placebo. In addition, the determination of 100 million leukocytes around the concentration of vitamin C found vitamin C was 60 micrograms, placebo was 43 micrograms. Dr. Pauling believes that the amount of vitamin C needed to prevent a cold varies from person to person, with a minimum of 250 milligrams and a maximum of 10 grams. In this experiment, the supply of vitamin C is lower than that prescribed by Dr. Pauling. Therefore, if not more than 50 mg of dietary intake of vitamin C, you can not expect to achieve the effect of preventing colds. This shows that dietary vitamin C content can not be ignored. In 1961 he conducted another experiment with 279 skiers in Switzerland. A group of daily service
