Abstract
飲食中的糖化終產物 (dietary advanced glycation end products, dAGEs) 主要源自於梅納反應。具代表性之 dAGEs 如羧甲基賴胺酸 (Nε-carboxymethyllysine, CML) 、羧乙基賴胺酸 (Nε-carboxyethyllysine, CEL) 及甲基乙二醛-氫咪唑酮 (methylglyoxal derived hydroimidazolone, MG-H1)。近來有研究顯示 dAGEs 的攝取可能會導致體內代謝產物以及腸道菌相之改變,且 dAGEs 的攝入與許多代謝慢性疾病具有正相關性。有鑑於此,本研究利用代謝體學探討 dAGEs對於高脂高果糖飲食誘發小鼠肥胖過程中所造成之健康影響。本研究首次證明給予 CEL 和 MG-H1 會顯著降低高脂高果糖飲食小鼠的體重,但給予加熱飼料會導致高脂高果糖飲食小鼠體重顯著的增加。血清生化分析的結果顯示,與高脂高果糖飲食組相比,給予 dAGEs 會明顯增加 LDL/HDL 比值。在代謝體學分析之結果顯示,給予 MG-H1 以及加熱飼料會導致高油脂飲食小鼠體內代謝產物異常,特別是脂質代謝產物。在腸道菌代謝物結果中,發現dAGEs顯著提升次級膽汁酸之合成,特別是給予MG-H1。另一方面,腸道菌相的結果顯示,dAGEs 會改變厚壁菌門與擬桿菌門的比值,進而導致體內腸道健康失衡。在相關性分析結果中,發現小鼠體內 AGEs與Bacteroidetes呈現負相關性;而與Faecalibaculum呈現正相關性,同時 Faecalibaculum 也與次級膽汁酸以及血脂指標物質呈現正相關性。綜合以上實驗結果,本研究證實飲食中的 dAGEs 會對於肥胖小鼠健康造成不良影響,特別是干擾體內脂質代謝,此不良影響與腸道菌相之改變有關。
