A number of investigations have disclosed that some characteristics of reducing diets causes obese young women to retain considerably less calcium and phosphorus than would be expected and desirable, in view of the optimum level of intake furnished. This characteristic of reducing diets which results in less efficient use of minerals has not been identified, although several hypotheses have been advanced. Other experiments have shown that calcium and phosphorus are better utilized when supplied from natural sources than as mineral-salt supplements.

Preliminary investigation in the Nutrition Research Laboratory suggested that young women receiving a semi-synthetic diet were losing phosphorus even though their intakes were believed adequate. Therefore this study was undertaken to determine whether subjects receiving adequate amounts of phosphorus while consuming a semi-synthetic diet were able to maintain phosphorus equilibrium. Two semi-synthetic diets differing in their content of natural foods were tested.
