Food is a complex mixture of macronutrients, micronutrients and other bioactive substances Macronutrients provide the necessary energy and basic building blocks for the synthesis of molecules and macromolecules in our body Adequate amounts and ratios of ingested nutrients are an important foundation of a healthy diet Certain components of macronutrients, such as essential amino acids and essential fatty acids, as well as all vitamins and minerals from the group of micronutrients, must be consumed in appropriate quantities A diet high in processed and refined foods can lead to excessive intake as well as deficiencies of certain nutrients Non-essential bioactive substances also have a significant influence on sensory properties, nutritional value and physiological processes A balanced and varied diet, including fresh vegetables and fruits, whole grains and legumes, as well as foods of animal origin, is the easiest way to ensure adequate intake of macronutrients and micronutrients
