脑的主要成分是蛋白质、脂类、以及对脑最有影响的硫胺素和尼克酸等维生素,故脑力劳动者的膳食应特别注意蛋白质和维生素的充足供应。而鸡蛋、牛奶、瘦肉等被称为优质蛋白并富含维生素和无机盐,这对花费大量脑力劳动的知识分子有增强大脑记忆力和防治神经衰弱的作用。如每日进食1～2个鸡蛋,就能满足人体对必需氨基酸的需要。 动物内脏营养丰富,利于健脑。肝、肾等动物内脏除富含蛋白质外,还含有丰富的维生素A、B_2和微量元素铁、锌、硒等,这些皆为人体易于缺乏又有健脑作用的营养素。 鱼虾等水产品比肉类更有健脑作用。鱼虾类含有丰富的牛磺酸,牛磺酸对脑细胞和脑神经的发育有重要作用,是健脑的重要物质。
The main components of the brain are proteins, lipids, and vitamins such as thiamine and niacin, which are most influential in the brain. Therefore, the mental worker’s diet should pay special attention to the adequate supply of protein and vitamins.
