We investigated the effect of olive oil, rapeseed oil, and sunflower oil on blood lipids and lipoproteins including number and lipid composition of lipoprotein subclasses. Eighteen young, healthy men participated in a double-blinded randomized cross-over study (3-week intervention period) with 50 g of oil per 10 MJ incorporated into a constant diet. Plasma cholesterol, triacylglycerol, apolipop...

Solvent fractionation of high oleic-high stearic (HOHS) sunflower oil was studied to determine the best solvent to use (hexane or acetone) in terms of the operational parameters and properties of the final stearins. Acetone fractionation on two types of HOHS sunflower oils (N17 and N20) was carried out at temperatures from 5 to 10 °C using micelles with different oil/solvent ratios. Acetone was...

Health benefits of lycopene from tomato products have been suggested to be related to its antioxidant activity. Dietary fat may influence the absorption and hence the plasma levels and antioxidant activity of lycopene. In the present study, we have compared the effect of consumption of tomato products with extra-virgin olive oil vs. tomato products plus sunflower oil on plasma lycopene and anti...

The role of dietary fat unsaturation and the supplementation of coenzyme Q have been evaluated in relation to bone health. Male Wistar rats were maintained for 6 or 24 months on two diets varying in the fat source, namely virgin olive oil, rich in monounsaturated fatty acids, or sunflower oil, rich in n-6 polyunsaturated fatty acids. Both dietary fats were supplemented or not with coenzyme Q10 ...

1 Sunflower (Helianthus annuus L.) is native to North America. American natives first cultivated sunflower 5000 yr ago in the present-day southwest United States (Semeslczi-Kovacs, 1975). Sunflower spread to the north and east in North America, where it was domesticated 4000 yr ago (Blackman et al., 2011). Sunflower is a relatively new commercial crop to the United States, with commercial culti...

OBJECTIVE Dietary supplementation with fish oil-derived n-3 fatty acids reduces mortality in patients with myocardial infarction, but may have adverse effects in angina patients. The underlying electrophysiologic mechanisms are poorly understood. We studied the arrhythmias and the electrophysiologic changes during regional ischemia in hearts from pigs fed a diet rich in fish oil. METHODS Pigs...

Sunflower (Helianthus annuus L.), belonging to the family „Asteraceae‟ is a diploid species (2n = 2x = 34). Sunflower is an important oilseed crop and is the preferred source of oil for domestic consumption and cooking worldwide (Hu et al., 2010). In the oilseed scenario, sunflower competes with other three major oilseeds, i.e. soyabean, groundnut and rapeseed mustard at global level. Sunflower...

This work was undertaken to determine the effect of diets enriched with olive oil or high oleic sunflower oil on very low density lipoprotein (VLDL) triacylglycerol composition of healthy human subjects. Both oils contain a similar proportion of monounsaturated fatty acids (MUFA) but differ in their triacylglycerol composition. All 22 human subjects initially consumed a low fat, high carbohydra...

Rats conditioned to eating fixed-size meals (meals at 7 AM and 7 PM), consuming diets rich in palm oil or sunflower seed oil, were used to study the metabolism of chylomicrons and hepatic very low density lipoproteins (VLDL) as a function of time after meal consumption. Rats fed a palm oil diet had higher serum triacylglycerol levels at 7 AM, before the meal (1.96 +/- 0.25 mM vs. 1.09 +/- 0.09 ...

High consumption of polyunsaturated fatty acids, such as sunflower oil has been associated to beneficial effects in plasma lipid profile, but its role on inflammation and insulin resistance is not fully elucidated yet. We evaluated the effect of sunflower oil supplementation on inflammatory state and insulin resistance condition in HFD-induced obese mice. C57BL/6 male mice (8 weeks) were divide...
