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

小麦中被称为“”水化合物可能占到一个人 FODMAP 摄入量一半。

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、难以区分零食棒中选择一种，这些零食棒要么含有纯麸质，要么含有一种叫 FODMAP，要么两者都没有，另一种是安慰剂棒。

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，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。
