Abstract
Okara, the soybean residue from soy milk production, contains nutrients and functional components. The proximate analysis was found to be 33.64% crude protein , 21.08% total lipid and 45.03% total dietary fiber in okara . The risk of development of diabetes type 2 is increasing worldwide in which the lifestyle and diet preference are primary responsible. In the current study, okara (rich source of fiber) has been manufactured into okara crackers which can be used to investigate its dietary role in controlling diabetes in STZ diabetic rats with and without high fat diet. 48 male albino rats were divided into eight groups (six rats in each group). G1, G2, G3 and G4 were healthy rats and fed on basal diet, basal diet with 30% okara crackers , high fat diet, and high fat diet with 30% okara crackers respectively. G5, G6, G7 and G8 were diabetic groups which fed on similar diets respectively as previous groups for 60 days. Blood glucose, liver function, kidneys function and lipid pattern of experimental animals in addition to pancreas and liver histopathology and insulin immunohistochemistry were carried out. Okara crackers diet has decreased the serum glucose level. The activity of AST, ALT and ALP were inhibited in diabetic rats fed on diets containing okara crackers. Uric acid , urea and creatinine content of diabetic rats which were significantly decreased after feeding on okara crackers compared with diabetic controlNazla
