Butter is made from cream, and cream is dairy — which means zero oxalate. Use butter freely on toast, in cooking, and in baking. The saturated fat content is a cardiovascular consideration (separate from kidney stones) but for oxalate tracking, butter is a non-issue. It also adds a small amount of calcium. Margarine and plant-based butter alternatives vary by brand — most are low-oxalate, but check the ingredients for nut oils or seed concentrates if you're being extremely careful.
