每天一粒DHA ，你投资什么，你就有什么样的回报

吃DHA的宝宝，智商比同龄人高7%-10%

眼睛亮，翻身动作灵活，

6个月抓握快，学龄前可以认识400-600个字。

发展没有可逆性，

不要错过今天，让孩子赢在起跑线上!

补充DHA，从孕期开始

因为大脑发育最最关键是阶段是

怀孕3个月--宝宝出生6岁

要知道，这个阶段是大脑发育的高峰期!

DHA是宝宝大脑发育不可缺少的营养素,这个观点已被大部分的妈妈们熟知。那么昂贵的DHA到底是什么东西?到底发挥着什么样的作用呢?我们来重新简明梳理一下。DHA 学名：二十二碳六烯酸，俗名 ：脑黄金DHA：是长链多不饱和脂肪酸的一种，在成熟的哺乳动物中占大脑脂质的10%。在我们人类的大脑皮层中脂质的20%，视网膜的50%都由DHA构成。它和蛋白质、糖类、其他脂类共同构成我们的中枢神经系统，是极为重要的脑部营养素。

缺乏DHA对婴幼儿的危害：

1、DHA是婴幼儿神经细胞发育过程中重要的营养成分，与其成长过程中的反应灵敏程度有很大关系。

2、缺少DHA，会导致儿童(尤其是婴幼儿)的学习能力下降，同时患神经系统疾病的机率也较高。

3、婴幼儿脑和视网膜发育过程迟缓或受阻，造成智力低下，视力障碍。

4、婴幼儿DHA严重缺乏者，将会对迅速发育的中枢神经系统造成不可逆转的严重危害。

5、缺乏DHA的婴幼儿体质虚弱，语言能力较差，说话时间迟缓

6、DHA、ARA的缺乏对于人体组织器官的发育，尤其是大脑和神经系统发育可能会产生严重不良影响。

7、DHA在视神经细胞及视网膜组织中的含量高达40-47，是婴幼儿和儿童视觉系统发育不可缺少的脂肪酸;补充DHA的婴儿在52个星期后，视觉明显比其他未进食DHA的健康婴儿灵敏。

8、DHA可以加速骨骼增长，防止骨质疏松。DHA可以减少妇女产后神经衰弱及产后抑郁症的发生。

9、国际营养组织建议，在怀孕期间，每天DHA的摄入量需增加300毫克，满足胎儿大脑和视觉神经发育对DHA的需求。

10、DHA是婴幼儿神经细胞发育过程中重要的营养成分，与其成长过程中的反应灵敏程度有很大关系。

缺少DHA对孕妇的危害：

1、胎儿脑细胞成长和视网膜发育不正常，导致反应迟钝，产生弱智、弱视、失明。

2、胎儿无法正常进行自身中枢系统控制的代谢，可能引起畸形、胎死腹中，导致早产、流产等。

3、研究表明：出生时体重过轻，其中年时患心脏病、高血压、糖尿病的比例高。

4、妇女在怀孕期间，如果缺少DHA，会影响胎儿大脑及神经系统的正常发育。补充DHA的哺乳期妈妈，她们孩子的视觉和语言发展指数明显高于其他孩子。

孕妇和婴幼儿啥时候补DHA最好?

DHA虽好，但是一定要选择合适的补充时机，这样才能达到事半功倍的效果。

孕妈孕妈最佳服用DHA时间实在怀孕20周以后，因为这个阶段是胎儿大脑中枢神经元分裂和成熟的最快时期，此时适量补充DHA，可以帮助胎儿的大脑发育，使宝宝更聪明。

婴幼儿6个月—2岁是宝宝生长发育最迅速的年龄段，DHA可以产生大量促使大脑发育的至关重要的激素，以满足宝宝的发育需要。另外，宝宝摄入适量的DHA，可以促使他的手眼协调能力更好，而且这一作用在2岁时最为明显。

宝宝吃什么可以补充DHA？

母乳

初乳中DHA的含量尤其丰富。不过，母亲乳汁中DHA的含量取决于三餐的食物结构。

配方奶粉

指添加DHA的配方奶粉。

鱼类

DHA含量高的鱼类有鲔鱼、鲣鱼、鲑鱼、鲭鱼、沙丁鱼、竹荚鱼、旗鱼、金枪鱼、黄花鱼、秋刀鱼、鳝鱼、带鱼、花鲫鱼等，DHA含量高的部分又首推眼窝脂肪，其次则是鱼油。

干果类

核桃、杏仁、花生、芝麻等。其中所含的α-亚麻酸可在人体内转化成DHA。

DHA制品

市面上有两种，一种是从深海鱼类中提取，另一种是从深海微藻中提取。
