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

Abstract

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.

The use of nano-sized eggshell powder for calcium fortification of cow?s and buffalo?s milk yogurts

“…This means that individuals should take calcium from external sources in the form of calcium supplements or from calcium-fortified foods. Several natural sources of calcium carbonate, such as oyster shell, are used now for this purpose (Ahmed et al, 2015;Lee et al, 2017).…”

Expression and Clinical Values of Serum miR-155 and miR-224 in Chinese Patients with HCV Infection

“…The biochemical data measured and how they were done we consult the corresponding references. 23 , 24 HCV-RNA detection: all subjects used SLAM96P fluorescence quantitative PCR instrument and reagent provided by Shanghai Hongshi Company to detect HCV-RNA before treatment. And we quantified produced RNA using A260/A280 ratio.…”

Key Insights, Tools, and Future Prospects on Oyster Shell End-of-Life: A Critical Analysis of Sustainable Solutions

“…For the development of such products, the granulometry of the oyster shell powder and its association with other elements have a direct influence on the bioavailability and solubility of calcium as was observed on ovariectomized and albino rats by oral administration. 25,26 The oral uptake of Mg-, Fe-, Cu-, and Zn-rich mollusk shell powder carries health benefits, however, the high bioaccumulation ability of oyster shell, higher than that of eggshells, suggests that traces of toxic heavy metals may often be present or can lead to adverse effect by oral or dermal route. 27 Therefore, caution and safety-oriented approaches are recommended for food, animal feeding or other human uses.…”

“…NOS powder is a potential natural and organic alternative for synthetic phosphate in pork-based products and has attracted substantial interest. , With a clean label, this calcium source acts as a real additive for food and health products , or animal feeding. − Different oyster shell powders are commercially available for their benefit effects against bone-related deficiencies.
