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 โ€” commonly 30-50% for plant foods โ€” 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 Carrots (Steamed or canned) at 9 mg per serving, at the low end of the family. Related forms in this family: Carrots (Raw) (30 mg).
