进化有利于在食物来源有限的条件下具有上级认知和身体能力的个体,因此可以通过间歇性饮食能量限制(ER)和锻炼来优化大脑功能。这种充满活力的挑战参与神经元中的适应性细胞应激反应信号传导途径,涉及神经营养因子、蛋白质伴侣、DNA修复蛋白、自噬和线粒体生物发生。通过抑制适应性细胞应激反应,暴饮暴食和久坐不动的生活方式可能会增加阿尔茨海默氏症和帕金森氏症,中风和抑郁症的风险。需要政府、家庭、学校和医生的共同努力,才能成功地实施将ER和运动结合在一起的大脑健康生活方式。
Evolution favored individuals with superior cognitive and physical abilities under conditions of limited food sources, and brain function can therefore be optimized by intermittent dietary energy restriction (ER) and exercise. Such energetic challenges engage adaptive cellular stress response signaling pathways in neurons involving neurotrophic factors, protein chaperones, DNA repair proteins, autophagy and mitochondrial biogenesis. By suppressing adaptive cellular stress responses, overeating and a sedentary lifestyle may increase the risk of Alzheimer’s and Parkinson’s diseases, stroke, and depression. Intense concerted efforts of governments, families, schools and physicians will be required to successfully implement brain-healthy lifestyles that incorporate ER and exercise.
