If you have chronic kidney disease or are starting treatment with dialysis, you will need to make adjustments to your diet to support your kidney function, reports Medline Plus. A good diet for the kidneys should contain a healthy balance of electrolytes, minerals and fluids. Seek out a dietician who specializes in diets for kidney function, according to Medline Plus. You can also follow certain dietary guidelines in order to promote your own kidney health.
Step 1
Reduce your phosphorous intake. Your kidneys play a role in controlling the levels of phosphorous in your bloodstream, reports the Mayo Clinic. If your kidneys aren't functioning properly, this could lead to an uncontrolled spike in your body's phosphorous levels, which in turn can elevate calcium and cause bone disease. While you can't avoid dietary phosphorous altogether, you can steer clear of foods high in phosphorous, such as milk, whole grains, dried beans and peas, organ meats, milk chocolate, and nuts and nut butters.
Step 2
Watch your potassium levels. Medline Plus reports that although your heart relies on normal levels of potassium to maintain its steady beat, impaired kidneys may fail to regulate potassium, resulting in a buildup. This can cause potentially unsafe heart rhythms. You can support a healthy balance of potassium by choosing wisely among fruits and vegetables. Medline Plus suggests avoiding fruits such as oranges, nectarines, kiwis, raisins, bananas and cantaloupes, as well as vegetables like asparagus, winter squash, potatoes, tomatoes and cooked spinach.
Step 3
Restrict your sodium intake. Even for people with healthy kidneys, too much sodium can result in water retention and bloat. When your kidney function is impaired,reports the National Kidney Foundation, your body retains extra sodium and fluid. Not only can this cause swelling and puffiness, but it can also lead to elevated blood pressure, shortness of breath, and fluid accumulation around your heart. You should limit or avoid table salt, salt seasonings, and foods high in sodium.
Step 4
Enjoy carbohydrates. Unless you're overweight, carbohydrates are actually a benefit to your kidney health, reports Medline Plus. Carbohydrates are a good source of energy, and in cases where your doctor has instructed you to limit protein, carbohydrates can be a good way to recoup lost calories. Medline Plus suggests getting your carbs through fruits, grains, vegetables, and even high-calorie treats like pies, cookies, and cakes, provided they are low in dairy, chocolate, nuts and bananas.
Step 5
Get plenty of iron. According to Medline Plus, people with kidney disease will need to increase their intake of iron. Some foods rich in iron include beef, pork, chicken, kidney and lima beans, and cereals especially fortified with iron.
