In connection with an assortment extending in the consumer market of enriched with vitamins and mineral substances foodstuffs a maximal dose of vitamins, iron and calcium has been estimated on the basis of theoretical full replacement of usual products and dishes by their enriched analogues with the maximal micronutrient content. Calculation was made proceeding from the recommended daily average set of products of a sanatorium diet, and also from average daily actual consumption of the basic groups of foodstuffs. The total sizes of theoretically possible maximal receipt of vitamins A, E and B12 calculated on the basis of the first approach, can exceed recommended on 30-75%, of vitamins C, B1, B2, B6, niacin, pantothenic and folic acids--in 2-3 fold, vitamin D and biotin--in 4,5-5,4 fold, additional receipt of calcium makes approximately 83%, iron--about 100%. "Theoretical" intake of vitamins with a real diet amount to 45-220% from recommended norms of their consumption, and additional receipt of calcium and iron can reach 56-99%. Considering negligible probability owing to small volume of manufacture of simultaneous daily replacement of all foodstuffs on enriched analogues (at a level of enrichment up to 50% from recommended daily consumption), the risk of micronutrients overdose is possible to be recognized insignificant.
在消费市场上,随着富含维生素和矿物质的食品种类不断增加,基于用富含最大微量营养素含量的类似物完全替代普通产品和菜肴的理论,估算了维生素、铁和钙的最大剂量。计算是根据疗养院饮食推荐的每日平均产品组合,以及各类主要食品的每日实际平均消费量进行的。根据第一种方法计算出的维生素A、E和B12理论上可能的最大摄入量,可能超过推荐量的30%-75%,维生素C、B1、B2、B6、烟酸、泛酸和叶酸的摄入量可能会高出2-3倍,维生素D和生物素的摄入量可能会高出4.5-5.4倍,额外摄入的钙约为83%,铁约为100%。实际饮食中维生素的“理论”摄入量为推荐摄入量标准的45%-220%,额外摄入的钙和铁可能达到56%-99%。考虑到由于同时将所有食品替换为富含微量营养素的类似物(富集水平高达推荐日摄入量的50%)的产量较小,导致同时摄入的可能性微乎其微,因此可以认为微量营养素过量的风险微不足道。
