Evaluation of food products fortified with oyster shell for the prevention and treatment of osteoporosis.

Production and evaluation of different diet formulas fortified with oyster shell for the prevention and treatment of osteoporosis. Eighty-eight female albino rats were recruited and divided into 11 groups (8 rats each). Group 1 represented negative control while the remaining groups were ovariectomized. Group 2 acted as positive control. Groups 3-5 were fed on basal diet. Groups 6-8 were fed on lentil soup while groups 9-11 were fed on vegetable soup. Group 4, 7, 10 were fed on diets fortified with oyster shell. Groups 5, 8 and 11 were fed on diet formulas fortified with calcium citrate. All calcium fortified diet formulas, especially lentil soup, have minimized risk factors associated with osteoporosis as indicated from the significant increase in tibial weight, total protein, total calcium and phosphorus with noticeable reduction in ALP activity compared to positive group. Maximum recovery was observed for diet fortified with oyster shell. These data suggest that food products fortified with oyster shell as natural and inexpensive source could be beneficial for the prevention and treatment of osteoporosis.
