一、深海鱼对人体益处多多 深海鱼,通常指在海平面下600米—2700米的鱼类,它们肉质雪白、细腻、口感嫩爽、纯正可口,是无污染的低脂肪高蛋白绿色食品,营养成分和含量比一般的鱼类更齐全、更丰富。 科学家发现,深海鱼对人体的益处体现在各个方面,例如除皱养颜;含有的活性离子钙极易被人体吸收;含有大量的维生素E、维生素C及胡萝卜素,可以抑制自由基(自由基会破坏基本的基因物质、细胞壁,导致癌症和心脏病)的活性,从而增强人体免疫力,防衰老、保青春。 吃鱼类以深海鱼为好,因为深海鱼的营养价值很高,里面的DHA和EPA等营养成分都是很高的,能够帮助宝宝的脑力和视力的发育,而且蛋白质和钙质的含量也很高,对人体非常有益。\x0d\x0a二、对儿童补铁的最佳选择 深海鱼富含DHA(二十二碳六烯酸)和EPA(二十碳五烯酸)。DHA有“脑黄金”之称,具有活化脑细胞的聪明因子,使得脑部的神经传导物质能比较容易去传达正确的信息,促进、协调神经回路传导作用,以维持脑部细胞的正常运作。它不但对儿童的脑发育起着非常重要的作用,还可提高视网膜的反射能力,强化和改善视力。 很多孩子需要补铁,通常都说菠菜补铁,但是让孩子吃菠菜补铁,只能是越吃越缺铁,因为菠菜中的草酸、鞣酸都会抑制铁的吸收,此外补铁食材还有猪肝,里面含有丰富的铁质,但多食动物肝脏容易沉积毒素,也不宜长期大量食用。因此,孩子补铁的最佳选择是深海鱼类,其次肉、蛋中含的铁质较为容易被吸收利用。\x0d\x0a三、对女性养颜保健一步到位 深海鱼中所含的DHA可预防乳腺癌,还能有效帮助皮肤保持年轻和滋润,起到延缓衰老的作用,让女性更健康更美丽。研究显示,三文鱼是所有深海鱼中对美容最具功效的鱼类。鱼中含有一种强效抗氧化成分虾青素,抗氧化能力是普通维生素E的550倍—1000倍,能有效抗击自由基,延缓皮肤衰老,同时还能够保护皮肤免受紫外线的伤害。在此要特别注意的是,煎炒、熬汤或清蒸美味时,三文鱼最宜煎煮至九成熟,外面熟透、内部仍保持橙红色时口感最好。由于三文鱼的维生素E含量不是很丰富,因此,如果想强化它的美容效果,最好与富含维生素E的食物一起烹制,如各种坚果、绿叶蔬菜、谷类等。\x0d\x0a四、对中老年增强机体免疫力 中老年非常熟悉的保健品“深海鱼油”,就是深海鱼的衍生产品。深海鱼内含有的大量多元不饱和脂肪酸,称为“深海鱼油”,其中所含的EPA有“血管清道夫”之称,可增强中老年抗病能力,降低血液中对人体有害的胆固醇,维持低浓度血脂水平,从而降低高血压、动脉硬化、心脏病、脑血栓等疾病的发病率,保持身体健康。但张海娟提醒:如果血液中甘油三酯高的患者,并不建议多吃深海鱼,因为毕竟鱼中含有脂肪酸,会合成脂肪。 EPA成分能防止脂肪沉积在血管壁内,抑制动脉粥样硬化的形成和发展,增强血管的弹性和韧性。因此它还能有效地防止血栓的形成,预防中风。\x0d\x0a 据专家介绍,深海鱼可增强机体免疫力,提高自身免疫系统战胜癌细胞的能力。在英国、美国和一些发达的国家中,它已被用来辅助治疗糖尿病、类风湿性关节炎等疾病。 此外,多吃深海鱼对老年人的视网膜有保护作用,主要是因为鱼肉中含有丰富的—3脂肪酸,对老年人的视网膜有保护作用。因此营养专家建议如果老人有条件,最好能一周吃一次深海鱼。
