Carbohydrates in wheat called " fructans" could account for as much as half of a person's FODMAP intake.

小麦中被称为“果聚糖”的碳水化合物可能占到一个人 FODMAP 摄入量的一半。

And they had them try 1 of 3 different, indistinguishable snack bars that had either pure gluten or a FODMAP called fructan or neither, a placebo bar.

他们让受试者从三种同的、难以区分的零食棒中选择一种，这些零食棒要么含有纯麸质，要么含有一种叫做果聚糖的 FODMAP，要么两者都没有，另一种是棒。

The human intestine can't break down or absorb fructans, so they make their way to the large intestine or colon, where they're fermented by bacteria, producing short-chain fatty acids and gases.

人体肠道无法分解或吸收果聚糖，因此它们会进入大肠或结肠，在那里被细菌发酵，产生短链脂肪酸和气体。
