Health is the most precious asset of a person and a prerequisite for quality of life and performance. Nutrition, in conjunction with physical activity and necessary hygiene, forms the foundation for the health of people of all ages. Especially in young years, a balanced diet is not only important for mental and physical development but also for the prevention of diet-related diseases. In industrialized countries, the nutritional situation has significantly changed in recent decades due to societal development processes, making it more challenging to manage nutritional wealth adequately. Childhood and adolescence are today more than ever characterized by a lack of physical activity, poor nutrition, and overweight. Risk factors for the development of diseases must be addressed early on, as the foundation for a healthy future is laid during these years.
