Function of Minerals in Nutrition1

R. B. Becker

Florida Agricultural Experiment Station

Abstract

The importance of mineral elements in nutrition long has been recognized. Jesus Christ displayed general knowledge of the value of common salt when, in the Sermon on the Mount (22), he spoke the words, "YE ARE THE SALT OF THE EARTH."

When chemistry was applied to problems of agriculture, mineral elements were found present in all living things. Emil Wolff (36) assembled many of these early analyses in his work, "Aschen-Analysen von landwirtschaftlichen Producten, Fabrik-Abfällen und wildwachsenden Pflanzen," published in 1871.

The elements concerning which much information is available include sodium, potassium, calcium, phosphorus, magnesium, sulphur, iron and copper, chlorine, iodine and fluorine, zinc and manganese (1, 3, 12, 33). Many other elements are present in small amounts as shown by spectroscopic analyses, but little is known of their functions in nutrition.
