“…Third, our results show that the NSE and UViSE did not have any important effect on cholesterol, triglycerides, HDL, VLDL, and glucose levels. It is supported by a previous study where strawberry seed oils had no significant effect on cholesterol, triglycerides, HDL, and LDL levels in rats (Pieszka, Tombarkiewicz, Roman, Migdał, & Niedziółka, ). In contrast with our data, others studies demonstrated that the strawberry improves the hyperglycaemia and blood lipid profile in human.…”

Flavonoids and polyphenols from the strawberry and other fruits have been proposed to reduce the oxidative stress produced by the obesity and her complications. Moreover, it has been proposed that irradiation with UV‐C to strawberry may increase the antioxidant capacity of this fruit. The aim of the present study was to explore the effects of the UV‐C on antioxidant capacity of strawberry in vitro and in vivo. Strawberry slices were irradiated with ultraviolet light‐C (UV‐C) at 1.2 W/m2/16.5 min; then, the power antioxidant was isolated from the nonirradiated and irradiated strawberry slices into an organic phase, which was lyophilized to finally producing a nonirradiated strawberry extract (NSE) and UV‐irradiated strawberry extract (UViSE) powder. After the antioxidant capacity of both extracts were determined in vitro using the Trolox equivalent antioxidant capacity (TEAC) assay and in vivo using high‐fat diet‐induced obese rats. Our results demonstrated that irradiation with UV‐C to strawberry slices increased the antioxidants content, which was corroborated in vitro, where the antioxidant capacity of UViSE was higher than the NSE. However, in obese rats, the reduction in the oxidative damage by the UViSE and NSE were similar in peripheral tissues. Interestingly, the UViSE was better than the NSE to reduce the oxidative damage in brain. In conclusion, UV‐irradiation increases the antioxidants content of strawberry that is correlated with an increased antioxidant capacity in vitro, but in rats, this antioxidant capacity may be more effective in brain than in peripheral tissues.

“…The RO used in this study was especially rich in linoleic and a-linolenic acids (18:3n23; 50.7% and 29.2%, respectively), which is similar to the results obtained by other authors who determined the FA profile of RO (6,10,26). However, in the aforementioned studies, the contents of linoleic and a-linolenic acid were higher by up to 4% and 5.5%, respectively, which can be a consequence of the different growth conditions of raspberries or the extraction method that was applied.…”

“…jn.nutrition.org reduction in lipoperoxide concentrations and superoxide dismutase to catalase enzymatic ratios as well as an increase in manganese superoxide dismutase concentrations. In addition, Pieszka et al (10) indicated that the administration of RO to rats by gavage for 5 wk led to a reduced cellular GSSG concentration in erythrocytes. This is in accordance with the present study, in which the liver GSH:GSSG ratio was partly increased by dietary RO.…”

“…Raspberry seed oil (RO) 4 is also a source of antioxidative vitamins and bioactive compounds, such as tocopherols, carotenoids, and polyphenols (3,8,9). Notably, a recent toxicologic study in Wistar rats showed some antioxidant activity of RO (10). Nevertheless, there is still a lack of nutritional experiments to assess potential benefits from the incorporation of RO into diets.…”

“…Pieszka and cols. (12) observed a reduction in the activity of superoxide dismutase and glutathione peroxidase enzymes in animals fed with di ets supplemented with strawberry and raspberry seed oils and concluded that these oils can improve the antioxi dant status and thus reduce oxidative stress. These results have increased the population's interest in the consump tion of vegetable oils with functional properties.…”

Objectives:To compare the effect of the consumption of buriti oil and soybean oil on the metabolism of rats under stress induced by iron overload. Materials and methods: A total of 28 rats were randomized into control groups who consumed diet added of soybean (CS) or buriti oil (CB) and gavage with saline and two experimental groups who consumed diet added of soybean (ES) or buriti oil (EB) and daily gavage with iron II sulfate as stress inducer. The fatty acid profile of diets was analyzed. Body weight and diet consumption were evaluated every two days. The lipid profile and liver weight of animals were evaluated at the end of the experiment. Results: Diet added of soybean oil showed higher percentage of polyunsaturated fatty acids (45.6%) and diet with buriti oil was rich in monounsaturated fatty acids (66.9%). There were no differences in food intake, total cholesterol, HDL-cholesterol and LDL-cholesterol among groups (p > 0.05). However, animals fed with diet supplemented with buriti oil showed intermediate triglyceride levels (CB: 65 mg/dL; EB: 68.7 mg/dL) compared to ES group (102.5 mg/dL). The liver of rats from the CS group had higher weight (2.06 ± 0.2 g) compared to the CB group (1.56 ± 0.1 g). Conclusion: Buriti oil consumption was able to minimize some changes related to iron overload. Arch Endocrinol Metab. 2015;59(5):422-7
