BookPublisher: 2016Description: 59p.Subject(s): PhysiologyDDC classification: 2723-T Dissertation note: Reuse of oil during food making is practiced worldwide. This practice is established not only by roadside food stalls but also customary to food outlets, restaurants and hotels in big cities. The process of heating and reheating of dietary oil results in oxidation of oil and generation of free radicals and toxic compounds. These toxic compounds cause red patches and necrosis in liver and kidney, antioxidants decreases also.
The consumption of multiple heated oil may affect liver and kidney health in male and female rats. Eighteen male and eighteen female Wistar rats were taken and divided into groups. Group-I (negative control) fed chow diet and sub-divided into two groups, based upon gender, IA (negative control males) and IB (negative control females). Group-II was given chow diet mixed with 15% v/w single time heated oil and sub-divided into two groups based on gender i.e., IIA and IIB. Animals in sub-groups IIIA and IIIB were fed on chow diet mixed with 15% v/w multiple heated oil. Blood samples were collected at the end of four weeks of study. Hepatic (AST, ALT, ALP, bilirubin) and renal (creatinine, blood urea nitrogen, uric acid) functions, oxidants and antioxidants (in blood and (liver, kidney) tissues) parameters were studied. Data were analyzed using two-way ANOVA on SPSS. Differences between the groups were compared by the Tukey’s test. Differences were considered significant at P < 0.05.
Upon feeding of fried oil liver and kidney damage occurred due to oxidation of oil. But in our present study single time and multiple time heated oil consumption did not damage liver and kidney. Alanine aminotransferase, aspartate aminotransferase and liver catalase significantly higher values in oil feeding groups confirm that chow diet was energy deficient whereas oil supplementation enhance diet energy.
