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.
