摘要

尽管越来越多的证据表明间歇性禁食(IF)对代谢健康有益,但很少有研究调查IF的影响是否与年龄有关。一项新的研究调查了IF对幼年(2个月)、中年(8个月)和老年(18个月)雄性C57BL/6N小鼠的影响,发现年龄影响IF对葡萄糖稳态的影响。更准确地说,虽然短期IF(5周)改善了所有年龄组的葡萄糖稳态,但长期IF(10周)仅改善了中老年小鼠的葡萄糖稳态,对年轻小鼠没有观察到的益处。进一步的实验表明,长期IF对青春期小鼠实际上是有害的,因为干预会损害α-和β细胞的增殖,导致胰岛功能和胰岛素分泌减少。这些结果表明,虽然短期IF显示出有希望的代谢益处,但由于潜在的年龄依赖性副作用,建议长期IF更加谨慎。原文献:Matta L.等。Cell rep 44, 115225 (2025)
