Each study was further divided into three groups to ensure the provision of selected diets, i.e.,control, functional and nutraceutical diets. Each study was further divided into three groups to ensure the provision of selected diets, i.e., control, functional and nutraceutical diets.Results: Declining trend for total cholesterol was observed in all studies with maximum reduction(8.55%) in rat group fed on nutraceutical diet in study Ⅲ. Likewise, levels of low density lipoproteins and triglycerides reduced 11.39% and 7.89% respectively in hypercholesterolemic rats. Moreover, nutraceutical diet alleviated the sera glucose level by 8.96% in study Ⅱ.Conclusions: Conclusively, inclusion of citrus peel bioflavonoids in dietary therapies is a promising strategy to modulate lipidemic and glycemic attributes without imparting any deleterious effect on hematological parameters.展开更多
