🥛 Calcium-Rich Dairy & Eggs — Protective Foods for Kidney Stones

Dairy and eggs form the safest corner of the database: nearly every item measures under 5 mg of oxalate, and most are at zero. Dairy also delivers the two things a stone diet needs most — calcium that binds oxalate in the gut, and fluid volume. The calcium-in-food (not calcium-supplement) message from the NKF and AUA is exactly why this category is foundational: milk, yogurt, and cheese protect against stones while being effectively oxalate-free. For stone patients, this is the category to build meals around rather than restrict.

The calcium-stone story is a reversal of intuition: dietary calcium is protective, not harmful. Calcium binds oxalate in the gut, so less reaches the kidneys. The NKF and AUA guidance is to get calcium from food — roughly 1,000-1,200 mg daily — rather than from supplements taken away from meals, since supplement calcium in isolation can move risk the wrong way. This category lists the foods that deliver that protective calcium alongside their oxalate data.

Among the 12 dairy & eggs foods shown here, the list is ranked by oxalate per serving so the safest options are immediately visible — scan the top of the grid for daily staples and treat the lower entries as portion foods.
