A healthy, daily diet can contribute to the prevention of all chronic diseases. How “Superfood” affects human health and which significance plant food has as “Superfood”, has been investigated in this diploma thesis. “Superfood” is primary comprised of plant foods, characterized by a high content of nutrients and ingredients, which show health promoting properties. In particular, the characteristics of “Superfood” have been investigated. Due to a critical reflection, the relevance of “Superfood” as a supplement in a daily diet has been examined. The principal focus was on seeds and berries, therefore, the processes of development of these components have been described in detail, in order to show the significance of the nutrition physiology of the plant food. The processes of the seed maturation and the germination present themselves as significant operations in the course of the development cycle of a plant. Further emphasis was put on secondary plant substances, whereby the antioxidant properties of anthocyanins, flavonoids, carotenoids and fat-soluble vitamins in plants and human organisms have particularly been explained. Finally, an analysis of scientific studies on the healthy effects of selected examples from “Superfood” have been made, after which chia seeds, basil seeds, hemp seeds, flax seeds, goji berries, açaí berries and blueberries have been presented as examples. The results revealed, that the consumption of “Superfood” could have positive effects on the human health, wherefore the consumption of plant food has been attributed with great importance. The scientific research concerning the aforementioned, however, is only at the beginning.
