Oxalate <25 mg/serving
Oxalate 25-99 mg/serving
Oxalate ≥100 mg/serving
Mangold's cousin — beet greens — deserve their own warning. While beet roots are moderate oxalate (48 mg), beet greens can exceed 200 mg per serving. The oxalate concentrates in the leaves, same as spinach and chard. If you buy beets with the greens attached, cook the root and discard or compost the greens unless you're specifically tracking and accounting for the oxalate. Beet greens are not a salad ingredient for kidney stone patients.
