848. 鱼油EPA或干扰脑部受损修复

from 知为谁 · host 知为谁

一项来自南卡罗来纳医科大学的新研究挑战了鱼油有益大脑的传统观念,指出其中的EPA脂肪酸可能在特定情况下产生负面影响。科学家通过实验发现,对于遭受反复轻度颅脑损伤的群体,过量摄入EPA会削弱脑血管的修复能力,并可能诱发与认知衰退相关的蛋白质堆积。研究强调,虽然另一种成分DHA通常被认为有益,但EPA在损伤环境下的代谢脆弱性可能导致血管稳定性下降,进而妨碍愈合。这项发现提醒公众,营养补充剂的效果高度依赖于个体的生理背景,盲目服用并非万全之策。该成果不仅为精准营养学提供了新思路,也为深入理解慢性脑损伤的康复机制奠定了基础。内容来源:https://www.cell.com/cell-reports/pdf/S2211-1247(26)00213-5.pdfhttps://www.sciencedaily.com/releases/2026/04/260426012303.htm
