The current practice of communication in the nutritional economy often produces significant uncertainty in a large fraction of the population. Efficient and comprehensive publicity by entrepreneurs on the industrial production of foodstuffs needs a new concept for communication between producers, processors, wholesalers, retailers, and end users. Without overgeneralizing, the author explains what makes the consumers uncertain and which consequences this uncertainty has for their nutritional behavior. The main aim of this book is the empirical explanation of the connection between the uncertainty concerning the health value of industrially produced foodstuffs and the behavior of consumers in relation to information. It shows how consumers currently perceive the publicity activities of the food industry and what their needs are as far as information is concerned. The practical consequences derived from the empirical results are comprehensibly described.
