The diet and nutrition of chronic kidney disease

2012-09-11 11:48

Low salt or sodium

Most people must limit the amount of salt in the diet, because it will aggravate the blood pressure and kidney disease. Even if you do not put salt in cooking, the diet may still be high in sodium. You can replace the salt with some safe herbs to flavor your foods. Generally, we should keep away from foods in high salt include:

Most of canned foods and frozen foods

Most processed meats, such as sausage, ham and cold cuts

Some snakes, such as crackers and chips

Some salty seasonings, such as teriyaki sauce or soy sauce

Most importantly, when go shopping in the markets, we need pay more attention to the labels of the foods. Some labels, such as low sodium, sodium free, unsalted or no salt added, we can put them in our shopping cart.

Low fat

For the patients with chronic kidney disease, you should be careful to use the cooking oil. Make sure to use the monounsaturated and polyunsaturated fats (such as safflower oil or olive oil), and limit the cholesterol foods, such as yolk, animal giblets and seafood. Talk to your doctor about the foods that you can eat.

Low potassium

Generally speaking, proper sodium in your blood can help our hearts beating steadily. However, if your kidneys are not functioning well, excess potassium will build up in your body and even lead to death. Therefore we need choose right foods and observe the intake of potassium. We can find potassium in many foods, such as fruits or vegetables.

Fruits: you can eat fruits, such as apples, peaches, watermelon, berries, pears, grapes, and so on.

You can not eat fruits, like kiwis, bananas, prunes, cantaloupe, nectarines, oranges, honeydew, etc.

Vegetables: you can eat vegetables, such as onion, lettuce, cucumber, broccoli, celery, eggplant, zucchini, and so on.

You can not eat vegetables, like potatoes, tomatoes or tomato sauce, asparagus, avocado, and so on.

Calcium and phosphorous.

Calcium is an important mineral in the body. However, in the early stages of chronic kidney disease, phosphorous levels in the blood can become too high, which will trigger the low calcium. So in this condition can cause your bones weaker and more likely to break. Therefore, we need to monitor the food we eat in our daily life.

Some dairy foods we can eat include (lower in phosphorous): cream cheese, brie cheese, ricotta cheese, tub margarine.

Some foods we can not eat include (higher in phosphorous): cheese, milk, or yogurt, etc.

At the same time, we should take calcium supplements to prevent the bone disease, and control the balance of phosphorous in the body with vitamin D.

Fine protein and low protein

Getting the right amount of protein is important to your overall health and how well you feel. The function of protein include: build muscles, repair tissue, and fight infections. Meantime, the proper intake of protein can also decrease too much waste in the body and may help the kidneys to work well and longer. In the daily life, we can get protein from eggs, milk, cheese, fish, chicken, and lean meats.

As for the right amount of protein, you should ask your doctor carefully and eat these foods prescribed by your dietitian.


There is no need to limit the amount of water even in the early stage of chronic kidney disease. One needs to monitor the water intake while kidneys are being worse or in during the dialysis. Because in the dialysis time, too much water will build up in the body and cause difficulty in breath (shortness of breath). Besides, keep away from foods that contain lots of water, such as watermelon, grapes, tomatoes or ice cream, etc.

Usually, you can feel less thirsty, if you eat less salty foods or stay cool on hot days.
