High FODMAP
Onions
Avoid during the elimination phase of the diet.
Onions deliver a pungent, aromatic flavor and a layered structure that softens and sweetens beautifully during cooking. They contain extremely high levels of fructans that rapidly ferment in the colon and provoke severe digestive distress. Consuming any standard portion frequently triggers intense bloating, cramping, and altered motility patterns. Strict elimination remains absolutely essential for individuals managing sensitive digestive function.

sticky_note_2 Clinical Notes
Remove all fresh, caramelized, and powdered onions from recipes, broths, and spice blends to prevent symptom flares. Substitute with green onion tops, fennel, and asafoetida to simulate aromatic depth without triggering fermentation. Always check restaurant menus and packaged foods thoroughly, as onion powder remains a hidden trigger in sauces, dips, and seasonings. Infuse oils with whole onions and remove completely before cooling to capture flavor without fructan transfer.
