INFLUENCE OF MAGNESIUM-DEFICIENCY AND SOY PROTEIN ON MAGNESIUM AND ZINC STATUS IN RATS
Additional Document Info
Female weanling Sprague-Dawley rats were fed casein or soy protein isolate based diets containing approximately 800 or 200 mg Mg/kg diet. Magnesium deficiency was reflected in reduced femur, carcass and plasma magnesium but not in hepatic concentration. Zinc concentration in bone was decreased in magnesium deficient animals. Plasma alkaline phosphatase and hemoglobin were depressed by magnesium deficiency. The enzyme levels were lowest in rats fed soy protein. The adverse effects on magnesium and zinc status were more pronounced than had previously been reported in response to mild magnesium deficiency for a shorter period of time. 1985 Pergamon Press Ltd.
