Effect of consuming common Pandora (Pagelluse rythinus) and cod liver oil on plasmalipidin human.

Abstract

Fish are one of the most important foods for individual's health, because their fats are involved in the formation of phosphorus lipids in the cell membrane. Many studies showed that fish fat is both nutritious and protective. They contain a group of unsaturated fatty acids (UFA), such as omega-3, which are essential to the human body. Indeed, these only can be obtained through food and supplements such as cod liver oil. This study was designed to determine the effect of consuming fish and intake of cod liver oil on the level of plasma lipids. This was performed on 42 subjects liveing Tripoli and aged between 25-60 years. They were divided into three groups; each group included 14 subjects (7 males and 7 females). The first group was on free diet plus 500 g / week of common Pandora fish meal (FMG), the second group was on free diet plus 3.3 g / week of cod liver oil (CLOG), while the third group was on diet free of fish and cod liver oil and designated as a control. The study lasted for 60 days, during which blood samples were withdrawn to estimate blood plasma fats: Total cholesterol, triglycerides, low density lipoproteins and high density lipoproteins (TC, TG, HDL, and LDL). The analyses of all parameters were carried 5 different times with a rate of one time every two weeks. Results showed that the cholesterol level of FMG had been significantly reduced by (P<5%) level. There was no statistical significance in the reduction of triglyceride levels in FMG or CLOG. On the other hand, statistically there was more response for the reduction in the triglyceride level in females (93 mg / dL), than males (122 mg / dL). Further more, only males in FMG showed a lower cholesterol level (135 mg / dL) and lower in LDL levels (78 mg / dL) with comparison to males control group (166 mg / dL, 98 mg / dL, respectively). The FMG of both sexes and the males of CLOG showed a reverse effect in the values of prothrombin time and there was no effect in such value in the females of CLOG. Although the introducing of fish in the meal twice a week or intake of cod liver oil with the amounts suggested to both sexes had showed reasonable results on lipid profile; it looks that the effect on some parameters could be more pronounced if the period of study lasted for more than 2 months.
