The kidneys are part of the urinary tract, working to rid the body of waste and excess fluid. Most people are born with two kidneys, but it is possible to function normally with only one. Like all organs, the kidneys are susceptible to cancer. While several types of cancer may strike, renal cell carcinoma is by far the most common. If you have kidney cancer, your physician may recommend a special diet.
Kidney Cancer Dietary Factors
While no direct correlation between diet and kidney cancer has been proven, some physicians encourage their patients to avoid excessive alcohol intake and high-protein diets as a way to help prevent kidney cancer. A healthy immune system can also help to prevent cancer, and eating a diet rich in vegetables, whole grains and fruits is beneficial to the immune system.
Kidney Cancer Diet
A healthy diet is important during cancer treatment. Eat the recommended five to nine servings of fruits and vegetables each day by choosing a variety of produce. Choose whole grains when possible and replace some animal protein with plant protein, such as nuts, seeds, beans and peas. Ask your physician if you should increase or decrease your total protein intake. While protein is good for your immune system, too much of it can put a strain on your kidneys. You may be instructed to reduce your salt intake, as sodium is also taxing for the kidneys.
Dietary Modifications After Kidney Removal
If you have a cancerous kidney removed, it is natural to feel protective of the remaining kidney. While there are no specific guidelines for eating with one functioning kidney, it is wise to avoid excess animal protein and alcohol. Ask your physician if you should modify your total fluid intake.
Fighting Obesity
Obese individuals with kidney cancer are often advised to lose weight, but this should be done gradually to avoid additional emotional stress. If you are told to lose weight during cancer treatment, make sure that you continue to eat an adequate amount of carbohydrates, protein, healthy oils, vitamins and minerals while consuming fewer total calories. Seek the services of a registered dietitian if needed.
Coping With Treatment Side Effects
Kidney cancer treatment can cause you to feel nauseated, lose weight and feel extremely tired. If you experience nausea or a loss of appetite, try to eat several small meals each day along with snacks. Choose foods you enjoy and avoid smelling cooking aromas when possible. Encourage yourself by saying "just five bites" and reward yourself with a good book, a talk with a friend or a relaxing bath. If you feel too fatigued to cook, choose sandwich foods or products that can be microwaved such as soup or frozen dinners.
