If you have chronic kidney disease, you'll need a diet that helps improve the function of your weakened kidneys. There's no cure for kidney disease, but you can slow down the progression of its symptoms by making some suitable dietary adjustments. Keep in mind that some individuals may need to limit their intake of potassium and phosphorus. With some time and effort, you can find a healthy diet that meets your needs. Remember, there isn't a one-size-fits-all diet, so it's essential to consult your doctor and a nutritionist to find the right plan for you.
Steps
Eat suitable foods

Select the right types of vegetables. When dealing with kidney disease, it's important to be cautious in choosing vegetables. Vegetables are a vital part of a healthy diet, but not all of them are safe for those with kidney issues. Generally, you should avoid vegetables high in potassium if you have kidney problems.
- Appropriate vegetables include: broccoli, cabbage, cauliflower, carrots, eggplant, lettuce, cucumbers, celery, onions, peppers, zucchini, and summer squash.
- Avoid potatoes, avocados, asparagus, pumpkins, winter squash, and cooked spinach, as these contain high levels of potassium.
- If you need to limit potassium, be sure to avoid high-potassium vegetables like potatoes. Instead, opt for lower-potassium vegetables like cucumbers and radishes.

Choose the Right Type of Fruit. You should be cautious when selecting fruits with high potassium content. While fruits are an essential part of a diet for those with kidney disease, it's important to choose the right types of fruit for your health.
- Low-potassium fruits include: grapes, cherries, apples, pears, berries, plums, pineapples, tangerines, and watermelon.
- Avoid oranges and orange products like orange juice. It's also wise to stay away from kiwi, peaches, dried plums, cantaloupe, honeydew, raisins, and in general, dried fruits.
- If you need to limit your potassium intake, opt for fruits that are low in potassium, such as blueberries and raspberries.

Consult Your Doctor About Your Protein Needs. Protein is an important part of your diet, but you must be careful about the amount of protein you consume when you have kidney disease. Too much protein can increase the workload on your kidneys. However, you may feel fatigued if you don't get enough protein. Protein generates waste in the body, and the kidneys help eliminate this waste, so excess protein intake can place unnecessary stress on the kidneys. Your doctor may recommend a low-protein diet. However, during dialysis, you might temporarily need to increase your protein intake.
- Find out the amount of protein you're allowed to consume daily and stick to it.
- Limit high-protein foods to about 140–200 g per day or less if advised by your nutritionist. High-protein foods include: red meat, poultry, seafood, and eggs.
- Pay attention to the protein content in other foods. Remember that protein is also found in milk, cheese, yogurt, noodles, beans, nuts, bread, and cereals. You need to track your total daily protein intake.
- Eat smaller portions of protein at dinner. Fruits, vegetables, and carbohydrates should make up the bulk of your meal. A serving of protein should not exceed 85 g, roughly equivalent to a deck of cards.
- High-protein foods may play an important role during dialysis, so consult your doctor if you're undergoing or will undergo dialysis. You may need to eat higher-protein foods during this period. Many doctors recommend eating eggs or egg whites as a suitable protein source during dialysis.

Prepare Healthy Meals. When it comes to slowing down or treating kidney damage, the way you prepare your meals is crucial. In general, it's important to learn how to cook healthier meals.
- Use a non-stick pan to reduce the amount of butter and vegetable oil, which add unnecessary calories and fats. Choose healthy fats like olive oil instead of butter or vegetable oil.
- When eating, remove fat from meat. Also, consider removing the skin when eating poultry.
- Try baking, stir-frying, or boiling your food instead of frying it.
Avoid Certain Types of Food

Closely Monitor Your Sodium Intake. Sodium, commonly known as salt, can be harmful when you have kidney disease. Cutting back on salt every day is extremely important. Reducing sodium also helps decrease fluid buildup in the body and control blood pressure, which in turn aids in treating kidney disease.
- Look for foods labeled "no added salt," "sodium-free," or "low-sodium."
- Check the product labels for the amount of sodium contained in each item. Choose products with less than 100 mg of sodium per serving.
- Do not add salt when cooking, and avoid adding salt to your food. If you have a salt shaker on the table, put it away to avoid the temptation of sprinkling extra salt while eating. Avoid salt substitutes unless your doctor or nutritionist approves.
- Avoid salty foods like salted crackers, chips, popcorn, bacon, deli meats, sausages, salted meats, canned meats, and canned fish.
- Steer clear of foods containing MSG.
- Cut back on eating out. Restaurant food tends to have more sodium than food cooked at home.

Limit the amount of phosphorus intake. Phosphorus levels in the blood should be kept low if you have chronic kidney disease. Dairy products such as milk and cheese generally contain high amounts of phosphorus. It is best to reduce dairy consumption when dealing with chronic kidney disease.
- For dairy products, stick to your recommended portion size per day and opt for low-phosphorus alternatives. Choose items like cream cheese, fresh cheese, plant-based butter, animal butter, heavy cream, diluted fruit juices, Brie cheese, or non-dairy whipped cream.
- Since calcium is essential for strong bones, consult your doctor about calcium supplements. Many individuals with chronic kidney disease need calcium supplements to maintain their health.
- You should also limit consumption of nuts, peanut butter, seeds, lentils, organ meats, sardines, and processed meats like sausages and hot dogs.
- Avoid drinking soda and other sugary beverages containing phosphates or phosphoric acid.
- Avoid whole wheat bread and whole grain cereals.

Avoid fried foods. When you have kidney disease, it's important to stay away from fried foods. Frying increases unnecessary calorie and fat intake.
- When dining out, avoid ordering fried dishes. Ask the server for alternative options. For example, you could ask to have grilled chicken instead of fried in a sandwich.
- At family gatherings, such as holiday meals, opt for vegetables and fruits instead of fried chicken.
- When cooking at home, refrain from making fried dishes. If you have a deep fryer at home, it might be a good idea to give it away to someone else.
Monitor your fluid intake.

Consult with your doctor to see if moderate alcohol consumption is safe. Alcohol can be harmful to the kidneys. If your kidneys are already weakened, it's essential to avoid excessive alcohol intake. If your kidney disease has progressed, you may not be allowed to drink at all. Some people with kidney disease can occasionally have a drink, but you should speak to your doctor to determine the safe amount of alcohol.
- If your doctor permits alcohol, ensure you don't exceed the recommended limit each day and include this alcohol intake in your overall fluid consumption.
- Encourage friends and family not to drink alcohol when you're around. If you know a party will involve alcohol, avoid attending or ask others to limit their drinking around you.
- If you struggle with quitting alcohol, consider talking to a therapist about how to quit. You may also want to find support groups if you believe you have an issue with drinking habits.

Find ways to control your thirst. You may not need to limit your fluid intake initially, but many people need to cut back on fluids as kidney disease progresses. If you're on dialysis, fluids may accumulate between treatment sessions. Your doctor may set a daily fluid limit that you must follow. Look for methods to manage your thirst without drinking too much.
- Use smaller cups during meals. If eating at a restaurant, you can flip your cup over once you're done, signaling to the server that you don't need a refill, helping you avoid the temptation to drink too much.
- Try freezing fruit juice in ice cube trays. You can suck on these fruit ice cubes like frozen fruit pops to slowly ease your thirst. Remember to count this liquid as part of your total daily allowance.
- If you're limiting your fluid intake, consider using a water bottle to track your allowed amount each day. Fill the bottle and only drink from it. If you consume something that counts as liquid—like coffee, milk, jello, or ice cream—pour out an equivalent amount from your bottle. Don’t forget to account for liquids from canned fruits, vegetables, soups, and other sources.

Be cautious with sodas. Generally, you should avoid drinking sodas as they are unnecessary sources of calories and sugar. However, if you occasionally crave one, it's better to choose clear sodas like Sprite over darker ones like Coca-Cola and Pepsi.
Make sure to steer clear of sodas that contain phosphate or phosphoric acid. Additionally, sodas are high in sodium, and reducing your sodium/salt intake is important.

Limit your consumption of orange juice. Orange juice has a high potassium content. If you have chronic kidney disease, it’s best to avoid drinking orange juice. Instead, try grape, apple, or cranberry juice as alternatives.
Advice
- Stay positive. Stress can exacerbate kidney disease.
- Regular exercise is essential. Staying active can help slow down the progression of kidney disease. You should also consider lifestyle changes like quitting smoking to manage your kidney health.
- Avoid skipping meals or going too long without eating. If you’re not feeling hungry, try having 4 or 5 smaller meals instead of just one or two large ones.
- Do not take any minerals, supplements, or herbal products without first consulting your doctor.
- Keep in mind that you may need to adjust your diet as your condition changes. Be sure to visit your doctor regularly for check-ups and consult a nutritionist to make dietary adjustments if necessary.
- Changing your diet can be challenging. You may have to give up some of your favorite foods. However, following recommended changes is essential to maintain long-term health.
Warning
- If you don't reduce your sodium intake, you won't notice any improvement in kidney function.
