The salt intake in school children´s diet
MIČULKOVÁ, Barbora
It is generally known that the intake of salt in civilized countries has been currently multiple times exceeding the recommended amount that was set by the World Health Organization to less than 5 grams per a day. In Czech Republic this dose has been exceeded up to three times. The aim of this bachelor thesis is to evaluate the amount of the salt in lunches at school cafeterias in regards to the current nutritional recommendations. The thesis is divided into two parts, theoretical and practical. The theoretical part is about importance of sodium and salt in human diet, recommended amount of salt for adults and children, and complications related to its excessive intake. Furthermore it focuses on the occurrence of salt in food, the reduction of the salt in the diet and the nutrition of children. In the practical part I worked with five school canteens in České Budějovice, that provided me with weekly menus along with the list of raw materials and the quantity of salt used in individual lunches. The sodium content was evaluated by the Nutriservis Professional application, in which I inserted the raw materials the lunches were cooked from. According to the equation, I converted the amount of sodium to the amount of salt, added the amount of salt contained in average portion served at school canteens and compared the total amount to 1,7 grams, which is supposed to be in one portion. Based on the results of the verbal evaluation tables, all the school canteens of the research group exceeded the recommended salt limit in all the observed days. Groups of foods that have greatly influenced their high salt content include bakery products, cheeses and meat products. More attention needs to be paid to this subject, on the part of parents, and school canteens.
