目的：调查黎巴嫩常见的2种鱼类的组织磷（P）水平、P与蛋白质的比例以及P与omega-3脂肪酸（omega-3-FA）的比例的季节性变化。我们的目的是确定是否适合饮食管理的肾脏patients.Design和设置：Siganus rivulatus（兔鱼）和Diplodus sargus（白色海鸟）被困在陷阱关闭海岸的贝鲁特，并在不同的季节在冰上运送到实验室。取出鱼片，在95 ℃下干燥至恒重，精细研磨，并在220 ℃下储存。测定蛋白质、磷、磷与蛋白质的比例以及磷与欧米茄3-FA的比例。结果：与白色鲷相比（食肉动物），兔鱼（藻类）的平均P含量（+/- SE）（895 +/- 32 mg/100 g vs. 1，132 +/- 23 mg/100 g; P < .0001），P与蛋白质的比值（+/- SE）显著降低（10.35 +/- 0.39对13.15 +/- 0.34 mg P/g蛋白质; P < .001），以及显著较低的P与ω 3-FA比率（+/- SE）（2.81 +/- 0.29对5.93 +/- 1.05 g ω 3-FA/g P; P < .005）。两种鸭肉中P含量随季节变化显著（P < . 0001）。P含量在8月最低，6月最高（P < .白色海水中磷含量4月最高，6月最低（P < .05）。兔鱼肌肉P蛋白质的比例和P欧米茄3-FA的比例是最少的8月，与一个显着更大的P欧米茄3-FA的比例在今年余下的时间。白色海鸟表现出更广泛的P蛋白质的比例和P ω 3-FA的比例的季节性变化相比，兔fish.Conclusion：由于存在的鱼类之间的差异和季节性变化的P水平，肾营养师可能需要确定季节性的近似组成的个别鱼类在不同的栖息地，并制定相应的饮食方案。尽管有这样的建议，油性海鱼仍然是透析患者的健康食物选择，如果鱼片没有骨头。(C)2012年，美国国家肾脏基金会（National Kidney Foundation，Inc.）All rights reserved.
Objective: To investigate seasonal variations in tissue phosphorus (P) levels, P to protein ratio, and P to omega-3 fatty acid (omega 3-FA) ratio in 2 species of fish that are commonly consumed in Lebanon. We aim to determine suitability for dietary management of renal patients.Design and Setting: Siganus rivulatus (rabbitfish) and Diplodus sargus (white seabream) were caught in traps off the coast of Beirut and transported on ice to the laboratory during various seasons. Fillets of fish were removed, dried to constant weight at 95 degrees C, finely ground, and stored at 220 degrees C. Protein, P, P to protein ratio, and P to omega 3-FA ratio were determined.Results: Compared with white seabream (carnivore), rabbitfish (algaevore) had a significantly lower mean P content (+/- SE) (895 +/- 32 mg/100 g vs. 1,132 +/- 23 mg/100 g; P < .0001), a significantly lower P to protein ratio (+/- SE) (10.35 +/- 0.39 vs. 13.15 +/- 0.34 mg P/g of protein; P < .001), and a significantly lower P to omega 3-FA ratio (+/- SE) (2.81 +/- 0.29 vs. 5.93 +/- 1.05 g of omega 3-FA/g of P; P < .005). P content in flesh of both species varied significantly with season (P < . 0001). Rabbitfish P content was least in August and greatest in June (P < . 05), whereas white seabream P content was greatest in April and least in June (P < .05). Rabbitfish muscle P to protein ratio and P to omega 3-FA ratio was least in August, with a significantly greater P to omega 3-FA ratio during the rest of the year. White seabream exhibited wider seasonal variation in P to protein ratio and P to omega 3-FA ratio as compared with rabbitfish.Conclusion: Because of differences and seasonal variations in P levels that exist among fish species, renal dietitians may need to identify the seasonal proximate composition of individual fish species in various habitats and formulate dietary regimens accordingly. Such advice notwithstanding, oily marine fish remain a healthy food choice for dialysis patients if the fillet is consumed without bones. (C) 2012 by the National Kidney Foundation, Inc.
