[Scientific approach in nutrition medicine and the example of diet fads]

The dietetics, seen from the historic point of view, have been more of an empirical science, yet in the past few decades they have developed a more rational, scientific basis. Unfortunately, this view is not shared by all, especially by those responsible for research policies of universities. Therefore it is not surprising that so-called "fad-diets" have gained in popularity despite the fact that these diets have not been scientifically proven as valuable. The most well known of these diets are the Schroth-, and F. X. Mayr-cure, the Evers-, Hay's, Atkins-, and Point-diet. Almost every day new diets are introduced to the public via uncritical mass media. These types of diets have nothing to do with modern throphotherapy.
