许多动物和人类研究表明,膳食补充非消化性碳水化合物(NDC)可改善食欲调节和体重。这些积极的代谢作用与结肠微生物群通过NDC发酵提高短链脂肪酸(SCFA)的产量有关。在主要的SCFA中,丙酸盐对游离脂肪酸受体2(FFAR 2)具有最高的亲和力,其在结肠L细胞上表达,并且在刺激时分泌厌食激素。因此,增加结肠丙酸盐是改善食欲调节的一个有吸引力的目标,作为BBSRC DRINC计划的一部分,我们开发了一种新的膳食分子,菊糖丙酸酯,我们证明它可以增加人类结肠丙酸盐水平。我们在人类志愿者中对菊糖丙酸酯的进一步研究表明,提高结肠丙酸水平的饮食干预可能是改善人群食欲调节和体重管理的一种策略。
A number of animal and human investigations have demonstrated that dietary supplementation with non‐digestible carbohydrates (NDC) improves appetite regulation and bodyweight. These positive metabolic effects have been linked to the elevated production of short chain fatty acids (SCFAs) through fermentation of NDC by the colonic microbiota. Of the principle SCFAs, propionate has the highest affinity for free fatty acid receptor 2 (FFAR2), which is expressed on colonic L‐cells and upon stimulation secretes anorectic hormones. Augmenting colonic propionate is therefore an attractive target to improve appetite regulation and, as part of the BBSRC DRINC initiative, we developed a novel dietary molecule, inulin‐propionate ester that we demonstrate increases colonic propionate levels in humans. Our further studies with inulin‐propionate ester in human volunteers suggest that dietary interventions that enhance colonic propionate levels may be a strategy to improve appetite regulation and weight management at the population level.
