Long chain n-3 fatty acids present in fish oils have been shown to reduce fasting plasma triglyceride and very low density lipoprotein levels in normal and hyperlipidemic human subjects. The present studies were designed to examine whether dietary n-3 fatty acids influence chylomicron formation and metabolism in healthy volunteers. In the first study seven subjects were fed either saturated fat...

Some groups of male Sprague-Dawley rats were fed a diet containing either 28% beef fat and 2% corn oil or 30% corn oil (high fat), and others were fed either 13% beef fat and 2% corn oil or 15% corn oil (moderate fat), for varying periods of time, with or without exposure to aflatoxin B, (AFBi). Assays for hepatic microsomal oxidases [p-nitroanisole demethylase and benzo(a)pyrene hydroxylase] w...

Release of volatiles in oil emulsion systems containing various fat contents was determined using purge-and-trap dynamic headspace/gas chromatography. Oil emulsions were prepared using 0, 0.5, 1, 2, 4, or 8% oil, and a standard mixture was prepared using hydrocarbons, aldehydes, ketones, and alcohols. Fat content in oil emulsions reduced the volatility of added volatile standards, and the amoun...

background: in recent years, dietary fat supplementation has become a common practice and fat supplemented diets have had variable effects on animal performance and carcass characteristics. objectives: this study was conducted to determine the effect of  increasing the levels of sesame oil on performance, rumen parameters and plasma lipid profile in finishing chal lambs. methods: eighteen male ...

Low-fat diets, in which carbohydrates replace some of the fat, decrease serum cholesterol. This decrease is due to decreases in LDL-cholesterol but in part to possibly harmful decreases in HDL-cholesterol. High-oil diets, in which oils rich in monounsaturated fat replace some of the saturated fat, decrease serum cholesterol mainly through LDL-cholesterol. We used these two diets to investigate ...

the effects of probiotics and antibiotics and fat type in diet on broiler performance were studied by using 900 one-day old ross 308 chicks in a three × three factorial arrangement with three types of fat (nonfat, three percent fatty acid and three percent soy oil) and three growth promoters (without gp, flavomycin and protexin) in completely randomized design with four replicates per each trea...

the demand for low fat snacks is increasing. there are different methods to produce low fat fried products. one of these methods is coating. in this study effect of carrageenan, oil temperature and frying time, on oil uptake of fried products (chips and strips) has been evaluated. samples were deep fried in frying oil (palm olein) at 160, 175 and 190 ºc. in order to evaluate the effect of fryin...

We examined the effect of dietary fats rich in n-3 polyunsaturated fatty acids (PUFA) on mRNA levels in white and brown adipose tissues in rats. Four groups of rats were fed on a low-fat diet (20 g safflower oil/kg) or a high-fat diet (200 g/kg) containing safflower oil, which is rich in n-6 PUFA (linoleic acid), or perilla (alpha-linolenic acid) or fish oil (eicosapentaenoic and docosahexaenoi...
