60年前,美国生理学家克莱夫·马克·凯和他的助手发现:大量减少老鼠食物中所含的热量,老鼠的寿命反而延长三分之一,由过去的3岁变为4岁。不仅如此,减少饮食的老鼠看上去显得年轻,很少罹患和衰老有关的疾病。这一发现引起了各国医学界的关注。 最近,瑞士的研究人员用减少热量摄入等特殊措施,使老鼠、苍蝇的寿命延长了1.2倍。美国国立老年研究所的查理·巴劳斯博士用大白鼠实验证实,从16月龄(相当于人类45岁)开始,把大白鼠的食物摄入量减少一半,可使其寿命延长三分之一。由此,人们推论,从中年
Sixty years ago, the American physiologist Clive Mark Kay and his aides found that a significant reduction in the calories contained in rat food resulted in a one-third longer life expectancy for mice, from the age of 3 to 4 years. Not only that, diet-reduced mice appear young, but seldom suffer from aging-related diseases. This discovery has drawn the attention of medical circles in various countries. Recently, Swiss researchers used special measures such as calorie intake to extend the lifespan of mice and flies by a factor of 1.2. Dr. Charlie Barrows of the National Institute of Aging has shown in rat experiments that starting from 16 months of age (45 years old), reducing the food intake in rats by half will extend the life expectancy by a third one. From this, people reasoned that from middle age
