Recently, it has even further suggested, based on a number of epidemiological studies, that our diet is also associated with the risk of developing a number of chronic diseases, such as diabetes type II, cardiovascular diseases, osteoporosis, many types of cancer, just to name few. Thus, a balanced nutrition is firmly interwoven with many aspects of our long-term health, including the prevention of diseases, albeit this is typically rather associated with the medicinal areas. Whereas medicine however usually is brought on stage when a disease has already appeared, the strength of dietary strategies would rather rest in its preventive potential. Apart from focusing on the macro-molecules in our diet, including carbohydrates, proteins, and lipids, a number of micronutrients such as vitamins and minerals, and also phytochemicals (non-nutrients), or secondary plant metabolites, have moved into the focus of attention. Among these are the most prevalent and large group of polyphenols, the lipid soluble carotenoids, but also less well studied groups such as terpenes. Albeit still lacking hard data in terms of randomized control, double blinded intervention studies on large scales, there exist now a number of prospective cohort studies that suggest that many of these phytochemicals, when consumed within e.g. a fruit and vegetable rich diet, are important contributors to our health, and this has been further supported by a number of studies focusing on the mechanisms of their biological activity. In addition to some of the antioxidant properties, which have been attributed to these compounds, additional mechanisms, such as impacting gene transcription and therefore altering the body’s own antioxidant defense system, or inflammatory cascades, may eventually be found to be of superior importance. Much research is currently focusing on these topics, and more studies in this area are warranted to reveal the potential of many of these compounds. The knowledge that many vitamins, minerals, and phytochemicals with no direct nutritive value are important for a healthy development is not new, but can be found in many dietary approaches, such as in the Chinese Traditional Medicine, which aims at closer linking specific food items for specific health conditions and diseases, i.e. targeting to extend our common view of nutrition as merely supplying sufficient energy and essential nutrients. Functional foods and nutraceuticals also aim toward this direction, and many interesting approaches with potential health benefits are VIII Preface under consideration. Among one of these strategies are also improved technological means, such as by increasing bioaccessibility and bioavailability of certain less stable ingredients, by encapsulation. Only time will reveal the potential of these new strategies to combat chronic diseases or aid in their prevention, but new possibilities in sight of the exploding number of chronic diseases, such as the metabolic syndrome, and the increasing age pyramid, are utterly needed. This special issue is based on selected chapters that deal with the above mentioned topics. Rather then aiming at giving an exhaustive overview over “Nutrition, Well- Being and Health”, which will virtually be impossible even in a large compilation of volumes, we chose to highlight some of the recent developments and investigations in this domain. We appreciate all the efforts that were bundled to bring this book together, and we would like to express our gratitude especially toward all authors and their valuable contributions.
