合理节食者美国老年研究所动物实验证明,限制饮食可极大地延长动物的生命。研究者们认为,限食可使机体的免疫力保持年轻化,推迟中枢免疫器官——胸腺的衰老。并可使自由基反应水平降低,减少引起衰老的物质——脂褐素在心脑等脏器的积聚。更为重要的是,限食可使哺乳动物体温降低,代谢减慢,从而使寿命延长。适度肥胖者美国某大学成人病研究所的安德鲁斯教授等发现,适当肥胖者其寿命更长,原因在于其抵抗疾病的能力比消瘦者更强。
Reasonable dieters American Institute of Aging animal experiments show that limiting the diet can greatly extend the life of animals. Researchers believe that food restriction can keep the body’s immune system rejuvenated, postponing aging of the central immune organ, the thymus. And can reduce the level of free radical reaction, reducing the material that causes aging - lipofuscin accumulation in heart and brain and other organs. More importantly, food restriction reduces mammalian body temperature, slows metabolism, and prolongs life expectancy. Moderately obese Professor Andrews of the Institute of Adult Diseases at a University in the United States found that those who are properly obese have a longer life expectancy because of their ability to resist illness more than those who are overweight.
