Onion salt
Is onion salt low FODMAP?
Onion salt is high FODMAP and best avoided during the elimination phase.
Salt blended with onion powder, and dried onion stays high in fructans at tiny amounts. Swap in the green tops of spring onions or chives plus plain salt for a milder onion note.
FODMAP subgroups to watch
Onion salt contains fructans that can drive SIBO symptoms.
SIBO note
Watch this one for ISO (hydrogen sulfide overproduction). Onion salt contains sulfur compounds, and ISO patterns can be more sensitive to these, especially in larger servings.
