进化规律显示,随着年龄的增长,大脑的变异与萎缩是自然的生理现象。一般认为,45—65岁是人的初老期,身体形态与切能即逐渐出现衰老现象;65岁以上为老年期;这期间大脑的萎缩会加剧。但是也不能因此任其自然衰老变异,而应坚持“可变论”观点,努力从食物上保证大脑供给,发挥食物功能优势,养育大脑,保持智力。 Evolutionary law shows that with age, brain variation and shrinking is a natural physiological phenomenon. Generally believed that 45-65 years old is the first period of human aging, body shape and cut that aging phenomenon is gradual; more than 65 years of age for the elderly; during this period the brain will shrink. However, we should not allow ourselves to change its natural aging. Instead, we should stick to the “variable theory” and try our best to ensure the supply of food from our food, give full play to the functional advantages of our food, raise the brain and maintain our intelligence.
