在胎儿期,脑的发育成长需要各种养料,其中以总热量和蛋白质最为重要。如果总热量和蛋白质的供应不足发生在脑细胞繁殖增生时期,或者在某一分区正在形成期间,那么,这些脑细胞的繁殖就会遭受严重影响,而且后天很难弥补。所以,妇女孕期必须注意饮食调养,注意进食清淡于和又具有丰富蛋白质、热能及多种营养的食物,如米、面、鸡蛋、瘦肉、鱼类、新鲜蔬菜、水果、动物肝脏等等。 另外一个重要问题,是脑神经最怕供氧不足,即缺氧。脑细胞的生长和发育,随时需要氧气。而氧气是由血液所提供。据测定,每分钟脑的耗氧量达到45毫升,占全身耗氧量的27％左右。如果氧的供应不足,轻者脑细胞受损,重者脑细胞死亡。这对智力的影响是相当 In the fetus, the development of the brain needs a variety of nutrients, of which the total calories and protein is the most important. If the total calories and protein deficiencies occur during the proliferation of brain cells, or during the formation of a subarea, the reproduction of these brain cells will be severely affected, and the acquired diseases are difficult to make up for. Therefore, women must pay attention to diet during pregnancy, pay attention to eating light and rich in protein, heat and a variety of nutritional foods such as rice, flour, eggs, lean meat, fish, fresh vegetables, fruits, animal liver and so on. Another important issue is that the brain is most afraid of oxygen deficiency, that is, hypoxia. The growth and development of brain cells, need oxygen at any time. And oxygen is provided by the blood. It is determined that the brain’s oxygen consumption per minute reached 45 ml, accounting for about 27% of systemic oxygen consumption. If the lack of oxygen supply, light brain cells damaged, severe brain cell death. This has a considerable impact on intelligence
