13 Foods You Need to Avoid If You Have Kidney Disease

Your kidneys in case you didn’t know filters blood, produces hormones, balances minerals and fluids, and removes waste from your urine. That’s quite a heavy load for those two bean-shaped organs and it’s up to you to keep them healthy by not overloading them. However, poor lifestyle and diet soon result in high blood pressure and diabetes that impact kidneys in a big way. Additional factors that cause kidney disease are alcoholism, hepatitis and heart disease. Once your kidneys are damaged and cannot function as well as they should, it becomes necessary to control what you eat simply because even certain healthy foods like bananas will exert a load on the kidney because of potassium content. There are several foods bad for kidneys and the dietary restrictions for the different stages of kidney disease are different and your doctor can advise you on a new diet. That being said, in general here are the main foods to avoid in kidney disease.


1 Dark-Colored Colas

As one of the foods to avoid in kidney disease, colas are a drink no doubt but they contain additive phosphorous one of the main kidney disease foods to avoid. In addition, colas contain calories and additives all bad for the kidney. Additive phosphorous is absorbed faster in our body than natural phosphorous which is why you need to avoid it completely.

3Canned Foods

Canned foods include soups, veggies, tuna, meats and beans and although they cost less, they are among foods bad for kidneys. This is because of the high sodium content due to salt being added as a preservative for longer shelf life. What you can do is to look for low sodium or no added salt varieties. To remove salt in canned foods, drain and rinse them thoroughly. This decreases salt content considerably.

4Whole-Wheat Bread

While whole wheat bread is usually recommended as a healthy nutritious choice over refined flour bread, it isn’t the same for those with kidney disease. The main reason is the high potassium and phosphorous content because more bran in bread means more potassium and phosphorous making brown bread one of the foods bad for kidney disease. A 30 gram serving of whole wheat bread contains 57 mg of phosphorous and 69 mg of potassium whereas white bread contains only 28 mg of both.
