PREPARATION AND EVALUATION OF SOME HEALTHY FOODS FOR ELDERLY

Abstract

The present investigation aimed to study the nutritional benefits and the health promoting effects of defatted soy bean (DSB) and defatted flaxseed (DFS) as dietary phytoestrogen sources of isoflavone and lignans, respectively; dried broccoli (BR) and dried red cabbage (RC) as sources of antioxidant; skimmed milk powder (SMP) as natural sources of calcium; by reason of they serve biological effectiveness and therapeutic roles in ovariectomized osteoporotic rats model, to give true for their potential application in prevention and treatment osteoporosis in elderly.

To fulfill this aim and to put into effect, ninety six aged female albino rats were used in this study, eight rats were chosen as initial group, other eight rats were taken as normal negative control group and fed on standard diet. The remaining eighty rats were ovariectomized and fed on low calcium diet for 8 weeks to produce osteoporotic rats model, 8 rats were chosen as an onset of experimental group, also, 8 rats were kept as a positive control group and fed on a standard diet. The reminder of osteoporotic rats were divided into 8 groups, each of 8 rats, and fed on standard diet supplemented with: DSB (GI), DSB with BR (GII), DSB with RC (GIII), DSB with mixture of BR and RC (GIV), DFS (GV), DFS with BR (GVI), DFS with RC (GVII), DFS with mixture of BR and RC (GVIII). Skimmed milk powder and vitamin D were added to each of diet groups. The feeding duration was 60 days, at the onset and the end of experiment, rats were weighed, blood samples were taken and serum was separated and exposed for its biochemical analysis, rats were sacrificed and organs were excited and weighed, femur and tibia bones were separated and subjected to their physical and chemical analysis.
