Hi, I can understand your concerns. There is no need to worry too much about the health of your kidney. Any food which is healthy for your heart will be good for the kidney also. Just take care of the following things in your diet: 1. Eat food rich in antioxidants. These include red pepper, red cabbage, red leaf lettuce, cauliflower, cherries, strawberries, cranberries, blue berries, plum, apple, red grapes, onion and garlic. Try to take as many colored food items as possible. 2. In animal protein, try to take egg white and fish instead of meat. 3. Use olive oil and vegetable oil instead of butter, lard and shortening. 4. Make sure you take regular and adequate fluids. Prevent dehydration. 5. Limit sodium intake (about 2.5 g/day). In addition to these aspects of diet, please note that hypertension, diabetes and hypercholesterolemia can worsen kidney function. You need to get checked for these diseases regularly and control them if you already have any one of them. Regular exercise is important to prevent and control these three problems. Regular medical check-up (as per your Urologist s advice) is important to diagnose and treat any precipitating factors early. Checking 24 hours urinary protein can show early damage to kidney. Proteinuria is a marker of kidney damage. If this is found in follow-up, it can be treated with specific drugs. Be positive...Eat healthy...
