随着高科技的发展,从事脑力劳动与神经系统紧张性作业的人日益增多,如科学研究、工程设计、技术革新、写作、教学等活动都是从事繁重而紧张的脑力劳动;操作仪表、处理数据、使用电脑等工作均属于神经系统高度紧张的工作。在从事这些活动时,中枢神经系统调节机制进行着精细复杂的活动,结合此期的生理特点调整膳食极为重要。 医学专家通过研究,认为脑力劳动者易出现四种生理特点: 1.机体对缺氧缺血极为敏感 人脑是具有复杂机能和旺盛活动力的器官,脑细胞主要靠血液输送进来的葡萄糖通过氧化作用而提供热量,故脑组织对缺氧、缺血最敏感。当人进行脑
With the development of high technology, there are increasing numbers of people engaged in mental and nervous system work such as scientific research, engineering design, technological innovation, writing, teaching and other activities are engaged in heavy and tense mental work; operating instrumentation, processing Data, the use of computers and other work are all highly nervous nervous system work. In carrying out these activities, the CNS regulatory mechanism carries out elaborate and complex activities, and it is extremely important to adjust the diet according to the physiological characteristics of this period. Medical experts through the study, that mental health workers prone to four physiological characteristics: 1. The body is extremely sensitive to hypoxia and ischemia in the human brain is a complex function and strong activity of organs, brain cells mainly through the blood glucose fed through the oxidation Role and provide heat, so brain tissue hypoxia, ischemia most sensitive. When people carry on the brain
