This Standard Reference Material (SRM) is intended primarily for use in the development and validation of analytical methods for the determination of cholesterol, fat-soluble vitamins, fat, and fatty acids in a lipid matrix. SRM 1563 consists of ten ampoules per unit: five ampoules of natural coconut oil (1563-1) and five ampoules of fortified coconut oil (1563-2). Each ampoule contains approxi...

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 ...

Male and female emus were fed a diet rich in saturated fat (beef tallow) or a diet rich in unsaturated fat (soybean oil) until they weighed about 35 kg. Samples of subcutaneous and retroperitoneal adipose tissues and samples of six major meat cuts were taken for determination of composition. Emus fed the two different diets grew at similar rates, but the male emus had a higher percentage of car...

to evaluate the effects of supplementation of tomato pomace (tp), canola, soybean and tallow oils on performance, carcass characteristics, and bone parameters of heat stressed broilers, 792 d-old arian broiler were divided to 36 pens. each dietary treatment had 4 replicate with 22 birds each. these factorial experiment (3*3) involved 3 kinds of canola, soybean and tallow oils and 3 levels of 0,...

It has been variously hypothesized that the insulin resistance induced in rodents by a high-fat diet is due to increased visceral fat accumulation, to an increase in muscle triglyceride (TG) content, or to an effect of diet composition. In this study we used a number of interventions: fish oil, leptin, caloric restriction, and shorter duration of fat feeding, to try to disassociate an increase ...

This experiment was conducted to investigate the effects of different levels of saturated and unsaturated fats and their composition in growing and finishing periods on performance, carcass traits and blood lipids level in broiler chickens. In this experiment, 432 Ross 308 broilers were used from 11 up to 42 days in 9 treatments, 4 replicates and 12 birds in each replicate in growing (11-24 day...

vegetable oils and fats have a big contribution in our diet as cooking or frying oil, salad oil or in food products formulation. they are important from nutritional and economical point of views. their authenticity is a serious issue since old time. some edible oils and fats such as olive oil, cocoa butter and milk fat are so expensive which makes tempting to adulterate them with other lower pr...

Fourteen crossbred lambs with an average weight of 29.4 kg were utilized to determine the influence of the nature and amount of dietary lipid intake on the qualitative and quantitative composit ion of the plasma lipid, carcass depot fats and plasma insulin levels. Formaldehyde treated casein-cottonseed oil (PCO) was supplemented at the rate of 8% (three lambs) and 12% (three lambs). Two groups ...

To test the hypothesis that conditioning with a practical dose of fish oil will reduce postprandial lipemia, 25 healthy men were matched according to levels of fasting plasma triacylglyceride and allocated to 6 weeks of either fish oil or olive oil supplements (5 g/day). After a 12-hour overnight fast at the termination of the study period, the subjects were given a standard test meal containin...

Uncoupling protein 2 (UCP2) is a possible target molecule for energy dissipation. Many dietary fats, including safflower oil and lard, induce obesity in C57BL/6 mice, whereas fish oil does not. Fish oil increases UCP2 expression in hepatocytes and may enhance UCP2 activity by activating the UCP2 molecule or altering the lipid bilayer environment. To examine the role of liver UCP2 in obesity, we...
