Frequently asked questions
Do the three names mean three different food ratings?
Luffa, sponge gourd and si qua are listed together in the checked source. This page follows that combined naming, using one set of references.
Does the range note make every luffa recipe low FODMAP?
It describes the raw vegetable. Sauces, fillings and other ingredients in a prepared dish need their own consideration.
Should I aim to eat the full 500 g range?
The source's upper range note is not a portion target. Choose a meal amount in context rather than treating a food-testing statement as a prescription.
