Eating a balanced diet that is rich in nutrients is crucial for maintaining healthy kidneys. Some foods that are good for kidneys include:

Fruits and Vegetables: Vitamins, minerals, and antioxidants are abundant in fruits and vegetables. They have a high potassium content and little sodium, which helps to keep blood pressure levels in a healthy range.

Whole Grains: Whole grains are a good source of fiber and help regulate blood sugar levels.

Lean Protein: Lean protein sources such as chicken, fish, and tofu are good for the kidneys as they are low in phosphorus.

Water: To keep your kidneys in good shape, you must drink water. Consuming lots of water aids in the body's detoxification process.
