BACKGROUND The effect of dietary pomace olive oil, which has the same concentration of oleic acid but a higher proportion of oleanolic acid (OA) than olive oil, was examined on animal models of hypertension for the first time. METHODS During 12 weeks, Wistar Kyoto (WKY) and spontaneously hypertensive rats (SHR) were fed with either a control 2% corn oil diet (BD), or high-fat diets containing...

The modulating effect of the combined dietary feeding of beta-carotene and perilla oil, which is rich in alpha-linolenic acid, on the development of azoxymethane (AOM)-induced colonic aberrant crypt foci (ACF) was investigated in male F344 rats. Rats received oral administration of beta-carotene (0, 50 or 200 mg/kg body weight/day) and fed a basal diet containing either 12% olive oil, 3% perill...

BACKGROUND Virgin olive oils are richer in phenolic content than refined olive oil. Small, randomized, crossover, controlled trials on the antioxidant effect of phenolic compounds from real-life daily doses of olive oil in humans have yielded conflicting results. Little information is available on the effect of the phenolic compounds of olive oil on plasma lipid levels. No international study w...

The effects of the amount of dietary fat and saturation together with cholesterol both on hepatic apolipoprotein A-I gene mRNA levels and on plasma levels of this apolipoprotein were studied in male rats. To achieve these goals, seven groups of male Wistar rats were established: control group (n=5) consuming chow diet; cholesterol group (n=4) fed on a chow diet containing 0.1% (w/w) cholesterol...

Different carbohydrate diets have been administrated to diabetic patients to evaluate the glycemic response, while Poor-controlled diabetes is increasing world wide. To investigate the role of an alternative carbohydrate diet on glycemic control, we explored the effect of a low glycemic load (Low GL)-high fat diet on glycemic response and also glycated hemoglobin (HbA1c) of poor-controlled diab...

In this paper, microcapsules were produced by complex coacervation using gelatin and acacia as wall materials and olive oil as the core substance. Process parameters, such as the dosage of the crosslinker, concentration of the wall materials, pH Value and the ratio between core and wall materials were analyzed in detail. Moreover, crosslinking degree of wall materials was more important in obta...

Applied Rheology Volume 21 · Issue 5 Abstract: The rheological behavior of the olive oil-in-water emulsions has been studied by varying the oil to water ratio as well as the surfactant concentration. The viscoelastic property of the olive oil emulsions was investigated with a cone-and-plate system, using a Bohlin C-VOR Rheometer. The obtained results indicated that the emulsions with greater oi...

This investigation was attempted in order to further clarify the effects of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on lipid metabolism in rats. Ninety-three percent ethyleicosapentaenoate (EPAconc) and 91% ethyl-docosahexaenoate (DHAconc) were used and supplied at the 3% level to a hypercholesterolemic basal diet which contained 5% lard. Four experimental diets were prepared...

A method is presented for measuring lipase activity in serum by use of either triolein or olive oil as substrate. The method requires 3 to 8 mm for each measurement and 5 to 8 mm for initial set-up. The reaction mixture is maintained at the optimum pH of 8.8 by automatic addition of sodium hydroxide (10 mmol/liter) with a ‘pH-Stat.” Amount of sodium hydroxide delivered per unit time reflects li...

Foods high in monounsaturated fat, such as olive oil, and endurance exercise are both known to independently reduce postprandial TAG concentrations. We examined the combined effects of exercise and dietary fat composition on postprandial TAG concentrations in nine healthy pre-menopausal females (age 26·8 (sd 3·3) years, BMI 22·3 (sd 2·0) kg/m2). Each participant completed four, 2 d trials in a ...
