美国的几位科学家用豚鼠做了如下的实验:将豚鼠分成两组,即实验组与对照组。他们用缺乏蛋白质的食物喂养实验组的豚鼠,用含有丰富蛋白质的食物喂养对照组的豚鼠。结果是:实验组的豚鼠无论在学走路还是走迷宫等方面的反应都不如对照组。由此可知,智力确实与营养有极大的关系。在大脑皮层中,含有大量的神经元和神经胶质细胞,它们担负着思维、学习、记忆、判断等功能。若孩子在母体怀孕期和哺乳期缺乏营养,那么脑细胞(包括神经元和神经胶质细胞)的发育就会大大减慢。这样,孩子的智力发展也会受到限制。但令人费解的是:一些营养很丰富、经常以营养品代食的孩子,长大后并不见得聪明。如果我们告诉他也是得了“营养不良症”时,他 Several scientists in the United States used guinea pigs to do the following experiments: The guinea pigs were divided into two groups, the experimental group and the control group. They fed guinea pigs in the experimental group with protein-poor food and those in the control group with protein-rich foods. The result is: the guinea pigs in the experimental group are not as good as the control group in terms of learning to walk or maze. This shows that intelligence does have a great relationship with nutrition. In the cerebral cortex, contains a large number of neurons and glial cells, they are responsible for thinking, learning, memory, judging and other functions. If the child is deprived of nutrition in the mother’s pregnancy and lactation, the development of brain cells (including neurons and glial cells) will be greatly slowed down. In this way, children’s intellectual development will be limited. However, it is puzzling that some children who are very nutritious and often replace their diet with nutrition products do not need to be smart when they grow up. If we tell him that he also got “malnutrition”, he
