High oleic acid sunflower oil (HOSO) is a monounsaturated oil that is being extensively used in frying. The level of total altered fatty acids and the fatty acid pattern of a fryer oil was used to evaluate the alteration of a HOSO used 20 times to fry various frozen foods with frequent replenishment (FR) or without replenishment (NR) with fresh oil during the frying. In addition, the levels of total altered fatty acids and the fatty acid composition of the fat extracted from the fried potatoes after numerous fryings were determined and compared to those of the corresponding fryer oils. Altered fatty acids increased linearly through 20 fryings within FR and NR in the frying oil and also in the fat extracted. Although differences were not quantitatively relevant, changes tended to be higher in the extracted fat, and in the NR modality as a consequence of oil renovation and fat exchange between the frying oil and the potatoes. The decrease in the oleic acid content in the oil was more pronounced ( p< 0.001) in NR than in FR method, and more (at least p< 0.01) in the oils than in the corresponding extracted fats. Nevertheless, other fatty acids remained quite stable and similar or increased during frying, by both methods. These results suggest that total fatty acid alteration measure is a useful tool for frying assessments, and that they must be related not only to the degradation of unsaturated fatty acids but also to migrations of some fatty acids from the frozen prefried foods to the fryer oil as revealed by composition of the fat extracted from the fried potatoes.

Introduction: Identifying dietary interventions for cardiometabolic disease prevention in individuals with metabolic syndrome is relevant to a significant portion of the population. Numerous studies have investigated the effects of canola oil on cardiovascular disease risk; however, no studies have compared canola oil diets to a control diet with a fatty acid composition characteristic of Western intakes in individuals with metabolic syndrome risk factors. The objectives of this study were to evaluate effects of canola oil, high-oleic acid canola oil (HOCO), and a control oil (blend of butter, safflower, coconut, and flaxseed oils formulated to represent a Western diet fatty acid profile) on lipids, lipoproteins, and apolipoproteins. Hypothesis: We tested the hypothesis that the two canola oil diets would elicit beneficial effects on the total lipid/lipoprotein profile compared to the Western (control oil) diet. Methods: In a multi-center, double blind, randomized, three-period crossover, controlled feeding clinical trial, 119 individuals with an increased waist circumference plus at least one additional metabolic syndrome risk factor consumed prepared isocaloric, weight maintenance diets containing canola oil [17.5% E from monounsaturated fatty acids (MUFA), 9.2% polyunsaturated fatty acids (PUFA), 6.6% saturated fatty acids (SFA)], HOCO (19.1% E from MUFA, 7.0% PUFA, 6.4% SFA), or control oil (11% E from MUFA, 10% PUFA, 12% SFA) for six-weeks each separated by 4-12 week washouts. The differences at the end of 42 days of feeding were tested. Results: The canola oil and HOCO resulted in lower endpoint total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), the TC: high-density lipoprotein-cholesterol (HDL-C) ratio, apolipoprotein (apo) B, the apoB: apoA1 ratio, and non-HDL-C compared to control oil ( P <0.0001 for treatment effect), with no differences between HOCO and canola oil for these parameters. Endpoint apoA1 did not significantly differ between the two canola oils and control, but was higher after the HOCO compared to canola oil (1.46 ± 0.02 g/L vs. 1.43 ± 0.02 g/L, P = 0.0462). There were no differences among the three diets in endpoint triglycerides or HDL-C. Conclusions: Incorporating canola or high-oleic acid canola oils into the diet improves blood lipids and lipoproteins compared to a contemporary Western diet in individuals with at least two criteria for metabolic syndrome.

The aim of this study was to measure the effects of 12 weeks of conjugated linoleic acid (CLA) supplementation on body composition, RER, RMR, blood lipid profiles, insulin sensitivity and appetite in exercising, normal-weight persons. In this double-blind, randomised, controlled trial, sixty-two non-obese subjects (twenty-five men, thirty-seven women) received either 3·9 g/d CLA or 3·9 g high-oleic acid sunflower oil for 12 weeks. Prior to and after 12 weeks of supplementation, oral glucose tolerance, blood lipid concentrations, body composition (dual-energy X-ray absorptiometry and computerised tomography scans), RMR, resting and exercising RER and appetite were measured. There were no significant effects of CLA on body composition or distribution, RMR, RER or appetite. During the oral glucose tolerance tests, mean plasma insulin concentrations (0, 30, 120 min) were significantly lower (P = 0·04) in women who supplemented with CLA (24·3 (sd9·7) to 20·4 (sd8·5) μU/ml) compared to high-oleic acid sunflower oil control (23·7 (sd9·8) to 26·0 (sd8·8) μU/ml). Serum NEFA levels in response to oral glucose were attenuated in both men and women in the CLA (P = 0·001) compared to control group. However, serum total cholesterol and LDL-cholesterol concentrations decreased in both groups and HDL-cholesterol concentrations decreased in women over 12 weeks (P = 0·001,P = 0·02,P = 0·02, respectively). In conclusion, mixed-isomer CLA supplementation had a favourable effect on serum insulin and NEFA response to oral glucose in non-obese, regularly exercising women, but there were no CLA-specific effects on body composition, energy expenditure or appetite.
