CALCIUM—Essential for the building of a sound bone structure. In all conditions of progressive demineralization due to the presence of a suboptimal amount of Vitamin D, there is a deficiency of calcium. In these cases Vitamins A and D must be given at the same time.
PHOSPHORUS—Associated with calcium in the regulation of bone formation but only if present in certain fixed proportions.
IRON—Forms the iron-protein combine ation of hemoglobin which carries oxygen to the tissues. Deficiency of iron results in acnemia.
COPPER—This element together with iron functions in the production of hemoglobin and produces a more beneficial effect in the treatment of certain types of acnemia.
MANGANESE—Appears to be associated with growth, reproduction and lactation.
MAGNESIUM—This mineral is found in chlorophyll and may be associated with the occurrence of rickets.
TODINE—Is an important constituent of the thyroid gland and plays an outstanding role in energy metabolism.
ZINC—It has been shown that crystalline insulin contains a constant small quantity of zinc. When the zine is removed from the insulin, the latter appears to be much less effective.
Mineral deficiencies may readily occur when one considers the possibility of demineralization of the soil due to intensive cultivation. Then too there is the very real possibility of loss of minerals in the water used for cooking various foods and subsequently discarded.
