[Sodium and potassium content of various Chilean foods]

Sodium and potassium contents of 40 high-protein dietary products were determined in order to complete the Table de Composición Química se Alimentos Chilenos (Chemical Composition Table of Chilean Foods). These cations' level must be strictly controlled in diets of many renal and heart patients. In Chile, Nutritionists who are in charge of preparing these diets, do not have a national composition table related to the sodium and potassium content for most of the food products. Samples of fluid cow's milk, dried milk with different fat contents, some cheeses, hen eggs, bovine entrails, some meat derivates and several meat cuts, including bovine, pork, lamb and chicken were studied.
