Healthy eating means, to a large extent, a healthy lifestyle. Proper nutrition improves physical and, by extension, athletic performance. Western-style diet includes poor dietary habits, which in the long run not only reduce physical and athletic performance but also create health problems. This way of eating can in no way be the basis of the diet for athletic performance, especially not for athletes and especially not for high-level athletes. Therefore, everyone should know about proper nutrition, the foods that promote performance (physical and athletic), and consume them in appropriate quantities according to their needs, in order to determine their individual dietary approach. This book is a valuable tool for every athlete, but also for anyone seeking a healthy way of life.
