Carrots are interesting because their oxalate changes with preparation. Raw carrots run about 30 mg per serving — into Caution territory. But cooked carrots drop lower, as some oxalate leaches into the cooking water. A handful of baby carrots as a snack is fine. A massive carrot juice cleanse is not. The bigger picture with carrots: they're rich in beta-carotene and fiber, and the oxalate is moderate enough that you don't need to eliminate them. Just don't make them your primary vegetable if you're watching oxalate closely.

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 Carrots (Raw) at 30 mg per serving, at the high end of the family. Related forms in this family: Carrots (Steamed or canned) (9 mg).
