Arugula
Arugula is a nutrient-dense green with low potassium levels, making it ideal for kidney-friendly salads and side dishes. Rich in vitamin K, manganese, calcium, and nitrates, arugula contributes to bone health and can lower blood pressure, which benefits individuals with kidney disease. A cup of raw arugula (20 grams) contains 5 mg of sodium, 74 mg of potassium, 10 mg of phosphorus, and 5 grams of protein.
