孕妇营养补充的黄金时间

1、孕妇营养补充的黄金时间备孕期，叶酸先行在还没有怀孕之前， 就必须迈出营养补充的第一步了， 只有这样， 才能为胎儿提供一个良好的坏境，也利于受孕。专家建议，至少在孕前三个月男女双方都要每天坚持补充叶酸，建议剂量为 0.6 毫克至 0.8 毫克。叶酸属于维生素 B 族群，可预防胎儿神经管畸形及其它畸形、早产。 在孕前就坚持补充叶酸， 可使得怀孕时叶酸达到预防神经管畸形的理想浓度，保证宝增强自身的免疫宝的健康。 另外，备孕女性在补充叶酸的同时，也要适当补充各类维生素，力，给胎儿提供一个健康的母体，建议服用含有叶酸的复合维生素片，内含各类营养元素，方便健康。孕早期，重在均衡孕早期是指怀孕的一到十二周，

2、 叶酸补充仍然是补充的重点， 特别是怀孕后的三到六周， 是定要保证叶酸在这一时期内达到理想浓度。胎儿中枢神经发育的关键时期， 一定要保证叶酸在这一时期内达到理想浓度。另外， 在孕早期，早孕反应强烈，孕妇通常会出现恶心、呕吐、眩晕等妊娠反应，食欲不振，胎儿容易缺乏营养。这一时期的饮食最好以清淡为主，少食多餐，加上一些辅食。这个时期，要适量地补充维生素 A维生素C铁和锌。早孕反应使得血清维生素A的水平下降，而维生素 A对胎儿的心脏发育影响很大， 如果严重缺乏， 会增加胎儿心脏畸形的危险， 患先天性心脏病的概率增大，因而孕早期要补充维生素 A,尽量多吃含维生素 A丰富的食物，如胡萝卜、南瓜、 青椒、

3、小白菜、油菜、肝脏、鸡蛋、牛奶和海产品、豆类等。但维生素A 一定要适量补充，否则会早成中毒现象。此外，锌的补充也不可忽视，医学家们认为，锌能促进脑部发育，预防早产、流产及早期畸形，缺锌将影响细胞的分裂和再生。 因此孕妈在整个孕期内及哺乳期， 都应适当补锌。 动物性食物含锌量高于植物性食物，而且生物利用率也高，如肉类、动物内脏、鲜蛋、牛奶及鱼虾类、海带、银耳、豆制品、花生米等含锌量也很高。蔬菜中锌的含量普遍比较低，其中含锌量较高的有油菜、萝卜、韭菜、黄花、大白菜等。孕中期，贵在丰富孕中期指的是怀孕的第 13 周到第 27 周，是胎儿生长发育的关键时期， 对各类营养的需求量都会增加， 因此这个时期

4、一定要做到各类营养都有足量的补充。 碳水化合物、矿物质。包括热量、 蛋白质、 维生素、热量和蛋白质、 碳水化合物的获得相对容易， 但并不是孕期营养的全部，实际上， 孕妇和哺乳期妇女对所有维生素、 矿物质和微量元素的需要量较多， 但对热量的需要较少。 也就是说，营养的补充， 主要是要体现在维生素和矿物质的补充量增大上。传统的烹饪方法往往会造成营养的流失，过多的食用水果不但寒性太大外，还会造成妊娠期糖尿病。因此，丰富的维生素和矿物质的补充， 仅仅靠食物并不能很好的解决，而应该适当地服用营养补充剂。 如爱乐维复合维生素片， 内含孕期所需的各类营养要素，根据国际标准进行调配， 全球唯一经随机双盲临床验

5、证。 每日一片即可满足孕期营养需求，孕妈妈们可以放心服用， 不用担心各类营养的剂量问题。在正常饮食外以复合维生素片作为补充，可保证胎儿在生长发育的关键时期 获得充足的营养，健康发育。孕晚期，适量而精怀孕的最后3个月，胎儿生长很快，孕妇的胃口比以往都要好，并且认为要为胎儿多提供营 养，进食量也就随之增加。实际上，靠食用传统食物来补偿营养，其蛋白质、脂肪、糖分含 量都会远远超标，而维生素、矿物质的补充又不足。长此以往，会引起孕妇过度肥胖，引发 妊娠期糖尿病、妊娠高血压疾病等，而胎儿则会体型过大，造成难产。因此，各类食物和营 养成分的补充都要做到适量补充。同时，孕晚期孕妇对钙 url=httP：/w

6、/基因育根/url的需要量明显增加,因为胎儿牙齿、骨骼钙化需要大量的钙，孕妇要多喝骨头汤、虾皮汤，多吃芝麻、海带、动物肝脏、蛋等食物。供给充足的必需脂肪酸，孕晚期是胎儿大脑细胞增值的高峰，需要提供DHA的供给。但总的来说，各类营养要素都是不可 因此，孕妇在做到均衡饮食的前提下，充足的必需脂肪酸以满足大脑发育所需，多吃海鱼可利于 如上所述，孕妇在各个时期时期都有不同的营养重点, 或缺的，只是有些时期对某一营养要素的需求量更大。最好辅以复合维生素药片，全面地补充各类维生素和矿物质，保证整个孕期，宝宝能够健康 地成长发育，用全面的营养呵护宝宝的健康。Pregnant wom
