How the form changes the number: preparation is the real variable across this family. Boiling leaches a meaningful share of soluble oxalate into the cooking water — commonly 30-50% for plant foods — while raw and dry-heat forms keep essentially all of it, so the same base food can land in different brackets depending on how it is cooked. This page tracks Broccoli (Raw) at 9 mg per serving, at the high end of the family. Related forms in this family: Broccoli (Boiled or steamed) (4 mg), Broccoli (Frozen) (1 mg).
