Bases and consequences of the newly recommended daily intakes of vitamins for the population of the German Democratic Republic

Abstract

In 1977 the official recommendations of the GDR for the daily intakes of essential nutrients were revised and extended. The criteria used to establish the revision and the extension in regard to the recommended vitamin intakes are given. For assessing the adequacy of food supplies and intakes vitamin intake data from national food consumption surveys and the weighted average recommended intakes for the entire population were compared. To give a true representation of vitamin amounts actually consumed, different forms of calculating losses on the way from harvesting or producing foods to the gullet have been applied. With the exception of tocopherol the daily intake of all vitamins considered permanently increased within the 10 years' period regarded, and the average levels of vitamin intake may appear satisfactory. Nevertheless, it is not valid to conclude that the vitamin needs of all individuals have been met.
