dietary factors are suggested to be involved in recent increases in the prevalence of asthma. the differences in dietary intake of 23 asthmatic and 317 non-asthmatic students were investigated, who were chosen by multistage stratified cluster sampling. the dietary data were assessed by food frequency questionnaire and a 24-h recall form. total calorie and fat intake were similar. daily intake o...

different layers of acorn (quercus infectoria), hull, seed coat and seed kernel were analyzed for determination of chemical composition. the results of the preliminary analysis showed that acorn contained more than 65% carbohydrates, 8% lipid and 10% tannin among other constituents. the fatty acid composition of the seed oil was determined using thin layer chromatography and comparing with ...

chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (pufas) are required for both animal and human health. the n-3 pufas, especially, eicosapentaenoic acid (epa) and docosahexaenoic ...

this experiment was designed to evaluate the effect of dietary caspian kilka fish oil on breast meat fatty acid (fa) profile and as well as sensory acceptability of breast meat. fish oil supplementation was added to provide four graded levels (0, 1, 2, and 3% fish oil) in place of vegetable oil for supporting 3% oil in the diet during the period of breeding. these four diets were allocated to o...

Dietary polyunsaturated fatty acids of the n-6 and the n-3 class show differing effects on serum lipids and hepatic lipoprotein metabolism, which could be induced by alterations in hepatocellular cholesterol balance. As both fatty acid classes exert parallel effects on lipoprotein uptake and synthesis of cholesterol in the liver, we studied whether they have differing effects on the excretory p...

Background & Aim: Purslane (Portulaca oleracea L.), belongs to the Portulacaceace family, grows in many parts of Iran. Results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6.  Portulaca oleracea is a widespread weed, being the eighth common plants of the world. The Aim of current study was to compare the essential f...

T here are good and bad fats. The Omega-3 is considered to be a good fat 1. Omega-3 fatty acids are considered essential fatty acids, which means that they are essential to human health but cannot be manufactured by the body. For this reason, omega-3 fatty acids must be obtained from food. Omega-3 fatty acids can be found in ¿ sh and certain plant oils and hence are the primary dietary source o...
