Effect of Variations in Dietary Protein, Phosphorus, Electrolytes, and Vitamin D on Calcium and Zinc Metabolism

Alterations in dietary levels of protein, phosphorus, vitamin D, calcium, and electrolytes, such as sodium and chloride, can produce a complex set of interactions. Each of these nutrients can influence the utilization of many other nutrients directly and indirectly. Sometimes the biological ef­ fect of one of these nutrients can be counteracted or modified by another.
