The food consumption of a sample of 10,000 French households has been under constant study by the Institut National des Statistiques et Etudes Economiques. Based on the data obtained, a representative model of the daily food consumption has been established with the help of the Nutrition Section of the Institut National de la Santé et de la Recherche Médicale. A composition table was used to define the theoretical amount of natural ascorbic acid contained in these foodstuffs, to this quantity was added the amounts of ascorbic acid incorporated as an additive in these foodstuffs. The latter amount was obtained using the maximum authorized amounts. Natural ascorbic acid plus additive gives the maximum theoretical amount of vitamin C supplied through food consumption. The mean value obtained is approximately 170-200 mg/day between 1965-1974 period. Interesting as they may be, from a nutritional point of view, it would be unrealistic to build upon these theoretical values. A critical analysis of these values based on the results of a food survey we carried out and the technological role played by ascorbic acid, led to the conclusion that food content, with this model of food intake, was somewhat between 56 to 91 mg/day and more probably between 56 to 69 mg/day. Kallner and al. in 1979 suggested that in the healthy non-smoking man the recommended dietary allowance should be 100 mg/day. In connection with this work and with nutritional studies undertaken in various industrial countries, the present study brings up the question of the level of vitamin C supply in certain groups of the French population (old people, pregnant women...).
法国国家统计与经济研究所一直在持续研究一万户法国家庭的食物消费情况。根据所获得的数据，在法国国家健康与医学研究所营养科的帮助下，建立了日常食物消费的代表性模型。使用成分表来确定这些食品中天然抗坏血酸的理论含量，并在此基础上加上作为添加剂添加到这些食品中的抗坏血酸含量。后一数值是使用最大允许量得出的。天然抗坏血酸加上添加剂得出了通过食物消费所提供的维生素C的最大理论含量。在1965年至1974年期间，所得平均值约为170 - 200毫克/天。尽管从营养角度来看这些数值可能很有趣，但基于这些理论值是不现实的。根据我们开展的一项食物调查结果以及抗坏血酸所起的技术作用，对这些数值进行批判性分析后得出结论，按照这种食物摄入模型，食物中的含量约在56至91毫克/天之间，更可能在56至69毫克/天之间。卡尔纳等人在1979年提出，健康的不吸烟男性的推荐膳食摄入量应为100毫克/天。结合这项工作以及在各个工业化国家开展的营养研究，本研究提出了法国特定人群（老年人、孕妇……）维生素C供应水平的问题。
