摘要
近年来,生酮饮食和酮体因其影响特定能量代谢和恢复线粒体稳态的能力而受到广泛关注,这有助于阻碍包括糖尿病和神经退行性疾病在内的许多代谢疾病的进展。生酮饮食由高脂肪和低碳水化合物组成,这使得身体葡萄糖被剥夺并依赖替代来源(酮体)获取能量。它最初是为治疗癫痫而设计和补充的,后来,它对许多产生能量的生化途径的影响使其成为许多代谢疾病的高度分类食品补充剂,甚至用于健康个体的健美和卡路里限制。在已报道的对一系列疾病的治疗作用中,神经退行性疾病,尤其是阿尔茨海默病,由于生酮饮食对这种疾病的更高益处而引起了许多研究人员和临床医生的关注。阿尔茨海默病的复杂病理和多重影响因素使得探索其治疗策略成为一项艰巨的任务。包括阿尔茨海默病在内的神经系统疾病的能量剥夺迅速发展是一种普遍现象。酮体稳定线粒体能量代谢的能力使其成为合适的干预剂。在这篇综述中,我们将讨论关于酮体/生酮饮食治疗阿尔茨海默病的各种研究进展,并详细阐述在其治疗作用期间受到影响的机制。
关键词: 生酮饮食、神经退行性疾病、阿尔茨海默病、代谢疾病、β-羟基丁酸 (BHB)、内皮功能障碍。
