Onions
Onions serve as a sodium-free flavour enhancer for renal-diet dishes. They offer vitamin C, manganese, and B vitamins like folate and prebiotic fibres that support gut health. Sautéing onions with garlic, olive oil, and herbs adds flavour without compromising kidney health. A small onion (70 grams) contains 3 mg of sodium, 102 mg of potassium, 20 mg of phosphorus, and 0.8 grams of protein. [8]
