Human evolution is accompanied by innovations in food processing. The results are remarkable: there is food security, as there is surplus on cheap, safe and high quality food. Despite this situation nutritional studies reveal that there are still nutritional problems in the world. Food security is only a precondition but no guarantee for nutrition security. The causes of nutritional problems are complex. In industrialised societies the importance of the last links of the food chain, being the competence of consumers regarding food and nutrition, is ignored. Whereas the global knowledge on food processing is increasing continuously, a reverse trend regarding consumer competence can be observed. The consequences of these trends have to be observed and studied. People with less food and nutrition competence are susceptible to disorientation and misguided behaviour. It is likely that the trend accelerates since the traditional ways to learn food and nutrition competence are diminishing; even in the case of food professionals, like cooks or bakers, there is clear evidence of lack of practical experiences. Nutrition and food policy has to focus on this gap. The most important nutritional problems are no longer those of food quality, but related to consumer behaviour. Today's consumers need high qualification to use all the opportunities to manage the everyday tasks. Without fostering such training (not only for the general population, but also for food professionals) we in Europe are in danger of becoming a food illiterate population.
