How much oxalate is in potato, baked (russet)?

Stone-former territory. Rare, small, or avoided.
Boiling instead of baking removes a meaningful share of soluble oxalate.
Most clinicians suggest calcium-oxalate stone formers stay under 100 mg of oxalate a day (stricter plans use 50 mg) — and eat normal calcium with meals, which binds oxalate in the gut. Values are estimates from published analyses; they vary by variety and preparation, so trust the band, not the decimal.
