要想宝宝在胎内发育好,孕妇的营养很重要,膳食要富有蛋白质、维生素、矿物质,摄入的热量要够,由于胎儿发育需要的营养是全面的,因而孕妇的营养也要全面,不要挑食、偏食,应该是平衡膳食。鱼的蛋白质丰富,远远高于肉类,含有人类需要的各种必需氨基酸,属优质蛋白,而且易消化,其消化率高达85～95%。鱼还含有丰富的维生素A、D,矿物质含量也高,常见的钙、磷、铁、锌、碘、钾、镁、氟化物等均很多。鱼的脂肪含量不多,但质量高,其他动物脂肪多是饱和脂肪酸,而鱼油多为不饱和脂肪酸,不仅可以预防心血管病,而且有利于神经系统发育。因此,怀孕的妈妈应多吃鱼。近年来,营养学的一大进展是发现鱼油中大量的多烯不饱和脂肪酸具有健脑、补脑、促进智力发育的作用。这些多烯不饱和脂肪酸包括22碳6烯酸(DHA)和20碳4烯酸(EPA)等,人体不能自身合成,必须从食物中摄取,属必需脂肪酸。这些营养物 To the baby in the fetal development well, the nutrition of pregnant women is very important, the diet should be rich in protein, vitamins, minerals, intake of enough heat, due to the nutritional needs of the fetus is comprehensive, so the nutrition of pregnant women should also be comprehensive, not Picky eaters, partial eclipse, it should be a balanced diet. Fish protein rich, far higher than the meat, contains all kinds of essential amino acids human needs, is a high-quality protein, and digestible, its digestibility as high as 85 to 95%. Fish is also rich in vitamins A, D, mineral content is also high, common calcium, phosphorus, iron, zinc, iodine, potassium, magnesium, fluoride, etc. are many. Fish fat content is small, but high quality, other animal fat and more saturated fatty acids, and fish oil mostly unsaturated fatty acids, not only can prevent cardiovascular disease, but also conducive to nervous system development. Therefore, pregnant mothers should eat more fish. In recent years, a major progress in nutrition is found in fish oil, a large number of polyunsaturated fatty acids with brain, Bunao, and promote the role of intellectual development. These polyunsaturated fatty acids include 22 carbon 6 acid (DHA) and 20 carbon 4 acid (EPA), the body can not synthesize their own, must be taken from the food, is an essential fatty acid.
