Verified step by step guidance

1. Understand the biological context: Kidney stones are solid deposits formed in the kidneys, often composed of calcium oxalate. Diet plays a significant role in preventing their formation or recurrence.
2. Analyze the options: A high-oxalate diet can increase the risk of kidney stone formation because oxalate binds with calcium to form calcium oxalate stones. Foods high in oxalate include spinach, rhubarb, and nuts.
3. Consider the role of sodium: A diet low in sodium is beneficial because high sodium intake can increase calcium excretion in urine, which may contribute to stone formation.
4. Evaluate hydration: Adequate hydration is crucial for kidney stone prevention as it dilutes urine, reducing the concentration of stone-forming substances.
5. Assess calcium intake: A diet moderate in calcium is recommended because dietary calcium can bind oxalate in the gut, preventing its absorption and reducing the risk of stone formation.
