Certain foods support kidney health by reducing inflammation and providing essential nutrients. Apples, berries (like blueberries and strawberries), bell peppers, and cabbage are rich in antioxidants that help protect kidneys. Fish high in omega-3 fatty acids, such as salmon, can reduce inflammation. Garlic helps reduce sodium intake as a natural flavoring, and onions provide nutrients that support kidney health. Foods like cauliflower and olive oil are also kidney-friendly.
