CHAPTER XVII MINERAL FOODS — SALADS USE of mineral matter in body : 1. Form bone. 2. Essential part of protoplasm. 3. Necessary for body fluids, etc. An average man excretes between twenty and thirty grams of mineral matter per day. This amount must be supplied to the body by food and beverages. The only mineral matter which is added directly to our food is common salt, sodium chloride (NaCl), all the others required being found in suffi- cient quantity in a well-balanced dietary. We probably consume much more common salt than is needed by the body, but it has a decided value as a condiment, improving the flavor of foods and hence making them digest more easily. . Mineral matter, as a rule, is found abundantly in fresh fruits and vegetables. Two of the most important minerals required by the body are lime (calcium, Ca) and iron (Fe). The other minerals are also of much importance, but are usually sup- plied by our foods in sufficient quantity for the needs of the body. Lime. — Three fourths of the mineral matter of the body is calcium phosphate, which is found in the bones, soft tis- sues, and in solution in the body fluids. Blood will not clot without lime salts, and they are necessary for the beating of the heart. 168 MINERAL FOODS — SALADS 169 Both organic and inorganic forms of lime may be assimi- lated by the body, even those which are insoluble in water. Animals that eat bones probably assimilate some of the lime; however, organic lime has greater food value than inorganic lime. A child must have a sufficient quantity of lime in its food or the bones will not grow properly, and general develop- ment of the body will be arrested. Milk is very rich in lime. Lime water is added to milk in infant feeding, not to increase the amount of lime, but to soften the casein curd so that it may digest more easily. Milk is richer in lime than lime water. Foods Rich in Lime Foods Poor in Lime Milk Meats Egg yolk Fish Peas, beans, turnips, oranges, Bread carrots, parsnips, spinach Polished rice Most cereals New process corn meal Iron. — Iron is found in the body chiefly in the red color- ing or hemoglobin of the blood. In this form it acts as an oxygen carrier, carrying oxygen from the lungs to all parts of the body. A deficiency of iron in the diet brings on anemia and other diseases of deficient oxidation. Chloro- phyll grains in plants cannot be produced without iron. If plants are grown in solutions free from iron, the leaves are colorless, but become green when iron salts are added. Iron is found as a constituent part of protein. Milk con- tains less iron than any other food, as the young animal is born with about three times more iron than is needed for its immediate use. Children kept too long on a milk diet become anemic. 170 DOMESTIC SCIENCE
