It is necessary for the body to absorb the energy and nutrients needed for the growth, development and health of the human body. In order to maintain health, improve and improve the quality of life, the body needs to be able to use adequate amounts of nutrients. Therefore, nutrition is an action that needs to be made consciously at the right times. Hippocrates (M.Ö 460-377) evaluated the foods in terms of Health and suggested diet recommendations for the diseases he defined. “Diet is the most effective medicine,” he told us centuries before the importance of diet. However, many people today have no knowledge about the nutritional values of different foods, their health effects, the relationship between the applied diet and the disease. However, malnutrition or imbalance is directly effective in the formation of some diseases, while in others it is indirect in terms of prolonging or shortening the course of the disease. Due to vitamin and mineral deficiencies goiter, anemia, rickets, pellagra, beriberi, protein deficiency in the lack of energy malnutrition is directly related to malnutrition diseases.

As a result of malnutrition, infection diseases, severe monitoring of diseases, delay in healing processes, diabetes, hypertension, cardiovascular diseases, obesity, liver and kidney diseases are indirectly the effects of malnutrition. With the participation of the World Health Organization (WHO) and the Food Agriculture Organization (FAO), the National Nutrition Congress was organized in Rome in 1992 and aimed to provide and support the use of strategies to improve adequate and balanced nutrition and nutritional consumption throughout the world. Thus, it is aimed to protect individuals against many diseases by improving the nutritional level of societies and to improve the quality of life. All studies to ensure the quality of life of society are helping to prevent malnutrition directly. Every institution that is applied to mass nutrition can prepare the ground for diseases directly or indirectly due to malnutrition and imbalance. Malnutrition can become a vital problem in a patient in a situation like malnutrition or imbalance. For this reason, patients should be carefully planned taking into account the history of the disease and the correct patient should be given the correct diet should be checked.
