Foods excessive in fructans

OK, buckle up: Lots of meals have fructans in them. They could be damaged down into two classes: Foods which have gluten in them and meals that don’t. In the everyday American food plan, the 2 greatest sources of fructans are wheat (which has gluten) and onions (which don’t). But there are many others that fall into these classes, too.

In the “has gluten” column are any typical bread merchandise, together with bread itself, together with pastries, pizza dough and so forth. High-fructan meals which have gluten in them embrace:

  • Wheat.

Because that’s the opposite factor: You could be ranges of fructan illiberal.
