孕妇的饮食禁忌大全孕妇的饮食禁忌大全 孕妇在饮食方面的禁忌很多,这里是妈妈说为孕妈妈们做的一个总结。希望对你有所帮助。 一、不宜高脂肪饮食 大量医学研究资料证实,乳腺癌、卵巢癌和宫颈癌具有家族遗传倾向。如果孕妇长期高脂肪膳食,势必增加女儿罹患生殖系统癌瘤的危险。 医学家指出,脂肪本身虽不会致癌,但长期多吃高脂肪食物,会使大肠内的胆酸和中性胆固醇浓度增加,这些物质的蓄积能诱发结肠癌。同时,高脂肪食物能增加催乳激素的合成,促使发生乳腺癌,不利母婴健康。 二、不宜高蛋自饮食 医学研究认为,蛋白质供应不足,易使孕妇体力衰弱,胎儿生长缓慢,产...

孕妇的饮食禁忌大全 孕妇在饮食方面的禁忌很多,这里是妈妈说为孕妈妈们做的一个。希望对你有所帮助。 一、不宜高脂肪饮食 大量医学研究资料证实,乳腺癌、卵巢癌和宫颈癌具有家族遗传倾向。如果孕妇长期高脂肪膳食,势必增加女儿罹患生殖系统癌瘤的危险。 医学家指出,脂肪本身虽不会致癌,但长期多吃高脂肪食物,会使大肠内的胆酸和中性胆固醇浓度增加,这些物质的蓄积能诱发结肠癌。同时,高脂肪食物能增加催乳激素的合成,促使发生乳腺癌,不利母婴健康。 二、不宜高蛋自饮食 医学研究认为,蛋白质供应不足,易使孕妇体力衰弱,胎儿生长缓慢,产后恢复健康迟缓,乳计分泌稀少。故孕妇每日蛋白质的需要量应达9O-100 克。但是,孕期高蛋白饮食,则可影响孕妇的食欲,增加胃肠道的负担,并影响其他营养物质摄入,使饮食营养失去平衡。研究证实,过多地摄入蛋白质,人体内可产生大量的硫化氢、组织胺等有害物质,容易引起腹胀、食欲减退、头晕、疲倦等现象。同时,蛋白质摄入过量,不仅可造成血中的氮质增高,而且也易导致胆固醇增高,加重肾脏的肾小球过滤的压力。有人认为,蛋白质宜过多地积存于人体结缔组织内,可引起组织和器宫的变性,较易使人罹患癌症。 三、不宜高糖饮食 意大利比萨国家研究院的医学家们发现,血糖偏高组的孕妇生出体重过高胎儿的可能性、胎儿先天畸形的发生率、出现妊娠毒血症的机会或需要剖腹产的次数,分别是血糖偏低组孕妇的3倍、7倍和2倍。另一方面,孕妇在妊娠期肾排糖功能可有不同程度的降低,如果血糖过高则会加重孕妇的肾脏负担,不利孕期保健。大量医学研究明,摄入过多的糖分会削弱人体的免疫力,使孕妇机体抗病力降低,易受病菌、病毒感染,不利优生。 四、不宜高钙饮食 孕妇盲目地进行高钙饮食,大量饮用牛奶,加服钙片、维生素D等,对胎儿有害无益。营养学家认为,孕妇补钙过量,胎儿有可能得高血钙症,出世后,患儿会囟门太早关闭、颚骨变宽而突出、邱粱前倾、主动脉窄缩等,既不利健康地生长发育,又有损后代的颜面健美。一般说来,孕妇在妊娠前期每日需钙量为 800毫克,后期可增加到1100毫克,这并不需要特别补充,只要从日常的鱼、肉、蛋等食物中合理摄取就够了。 有些孕妇为了使胎儿健康活泼,盲目地大量服用鱼肝油和钙质食品。这样对体内胎儿的生长是很不利的。因为长期大量食用鱼肝油和钙质食品,会引起食欲减退、皮肤发痒、毛发脱落、感觉过敏、眼球突出,血中凝血酶原不足及维生素C代谢障碍等。同时,血中钙浓度过高,会出现肌肉软弱无力、呕吐和心律失常等,这些对胎儿生长都是没有好处的。有的胎儿生下时已萌出牙齿,一个可能是由于婴儿早熟的缘故;另一个可能是由于孕妇在妊娠期间,大量服用维生素A和钙制剂或含钙质的食品,使胎儿的牙滤泡在宫内过早钙化而萌出。因此,孕妇不要随意服用大量鱼肝油和钙制剂。如果因治病需要,应按医嘱服用。 五、不宜过度咸食 有些孕妇由于饮食习惯嗜好咸食,尤其是北方居民较严重,多咸食。现代医学研究认为,吃盐量与高血压率发病有一定关系,食盐摄人越多,高血压病的发病率也越高。众所周知,妊娠高血压综合症是妇女在孕期才会发病的一种特殊疾than ? 5mm; elevation deviation was less than ? 5mm work surface height difference is not more than 3mm on the one end to the other end; wrong tooth at the joint is less than 1mm.

Side rail mounting: side rail installation take each side rail on two points. During the installation process, use tensioner to adjust the side rail. Side rail hole top center within the scope of the work is less than +2~-1mm, scope of work at a 4-to-2; wrong tooth less than 1mm at the joint work surface flatness 2mm lateral curvature RADIUS is less than ? 5mm sealing plate surface distortion is less than 1mm. Reinforcement process of adjustment is completed, in order to prevent tank deformation or displacement, welded tank side of the door, then welded reinforcing side, lap length is not less than 100mm.

Mode with the side rail. Grid slot bi-directional gate leaf on a car lift and lower grille blade adjustment is completed with pin connection, then try connecting rod.

Side rail mounting: side rail installation take each side rail on two points. During the installation process, use tensioner to adjust the side rail. Side rail hole top center within the scope of the work is less than +2~-1mm, scope of work at a 4-to-2; wrong tooth less than 1mm at the joint work surface flatness 2mm lateral curvature RADIUS is less than ? 5mm sealing plate surface distortion is less than 1mm. Reinforcement process of adjustment is completed, in order to prevent tank deformation or displacement, welded tank side of the door, then welded reinforcing side, lap length is not less than 100mm. Door installation: the lintel the installation focuses on family Center sill plane distance h is less than ? 3mm; work surface flatness of less than 2mm; combination of surface dislocation is less than 0.5mm surface distortion is less than 1.5mm. Mode with the side rail. Grid slot bi-directional gate leaf on a car lift and lower grille blade adjustment is completed with pin connection, then try connecting rod. After you check the accessories complete the fastening, hanging out the bottom opening and closing test in still water as a whole. 8.2.3 tainter and hinge installation Setup: Pivot fixed bearing installation ? orbit stitching, alignment ? arm splicing, installation connected with the headstock ? ? ? welding door leaf side connecting plates welded, water seal installation ? clean, and wipe off. 8.2.3.1 hinge installation and 的 30倍以上。由此判断铝的超量对人的大脑是极为不利的。在油条的制作时,须加入一定量明矾,而明矾正是一种含铝的无机物。炸油条时,每500克面粉就要用 15克明矾,也就是说,如果孕妇每天吃两根油条,就等于吃了3克明矾,这样天天积蓄起来,其摄入的铝相当惊人了。这些明矾中含的铝通过胎盘,侵入胎儿的大脑,会使其形成大脑障碍,增加痴呆儿的机率。 十五、孕妇不宜吃热性香料 八角茴香、小茴香、花椒、胡椒、桂皮、五香粉、辣椒等热性香料都是调味品,但孕妇食用这些热性香料则不适宜。妇女怀孕,体温相应增高,肠道也较干燥。而热性香料其性大热且具有刺激性,很容易消耗肠道水分,使胃肠腺体分泌减少,造成肠道干燥、便秘或粪石梗阻。肠道发生秘结后,孕妇必然用力屏气解便,这样就引起腹压增大,压迫子宫内的胎儿,易造成胎动不安、胎儿发育畸形、羊水早破、自然流产、早产等不良后果。所以,孕妇不宜吃热性香料。 十六、孕妇不宜多吃冷饮 孕妇在怀孕期,胃肠对冷的刺激非常敏感。多吃冷饮能使胃肠血管突然收缩,胃液分泌减少,消化功能降低,从而引起食欲不振、消化不良、腹泻,甚至引起胃部痉挛,出现剧烈腹痛现象。孕妇的鼻、咽、气管等呼吸道粘膜往往充血并伴有水肿,如果大量贪食冷饮,充血的血管突然收缩,血液减少,可致局部抵抗力降低,使潜伏在咽喉、气管、鼻腔、口腔里的细菌与病毒乘机而人,引起嗓子痛哑、咳嗽、头痛等。严重时能引起上呼吸道感染或诱发扁桃体炎。有人发现,胎儿对冷的刺激也极敏感,当孕妇喝冷饮时,胎儿会在子宫内躁动不安,胎动变得频繁。因此,孕妇吃冷饮一定要有所节制。 十七、孕妇不宜多吃山楂 大部分妇女怀孕后有妊娠反应,而且爱吃酸甜之类的东西。但要注意的是山楂果及其制品,孕妇以不吃为宜。现代医学临床证实:山楂对妇女子宫有收缩作用,如果孕妇大量食用山楂食品,就会刺激子宫收缩,甚至导致流产。因此,孕妇多吃山楂是不适宜的。 十八、孕妇忌食用过敏食物 众所周知,吸烟、喝酒、滥用药物对胎儿的危害很大。而孕妇食用过敏食物对胎儿发育的影响尚未引起人们的重视。事实上,孕妇食用过敏食物不仅能流产、早产、导致胎儿畸形,还可致婴儿多种疾病。 据美国学者研究发现,约有50%的食物对人体有致敏作用,只不过有隐性和显性之分。有过敏体质的孕妇可能对某些食物过敏,这些过敏食物经消化吸收后,可从胎盘进入胎儿血液循环中,妨碍胎儿的生长发育,或直接损害某些器官,如肺、支气管等,从而导致胎儿畸形或罹患疾病。因此,可从下面五个方面进行预防: (l) 以往吃某些食物发生过过敏现象,在怀孕期间应禁止食用。 (2) 不要吃过去从未吃过的食物,或霉变食物。 (3) 在食用某些食物后如发生全身发痒、出荨麻疹或心慌、气喘、或腹痛、腹泻等现象,应考虑到食物过敏,立即停止食用这些食物。 (4) 不吃易过敏的食物,如海产鱼、虾、蟹、贝壳类食物及辛辣刺激性食物。 than ? 5mm; elevation deviation was less than ? 5mm work surface height difference is not more than 3mm on the one end to the other end; wrong tooth at the joint is less than 1mm. Side rail mounting: side rail installation take each side rail on two points. During the installation process, use tensioner to adjust the side rail. Side rail hole top center within the scope of the work is less than +2~-1mm, scope of work at a 4-to-2; wrong tooth less than 1mm at the joint work surface flatness 2mm lateral curvature RADIUS is less than ? 5mm sealing plate surface distortion is less than 1mm. Reinforcement process of adjustment is completed, in order to prevent tank deformation or displacement, welded tank side of the door, then welded reinforcing side, lap length is not less than 100mm.
