People who are undergoing treatment for renal cancer require proper nutrition and a healthy diet to help them remain strong. It is common to lose weight during treatment for renal cancer. As a result, a healthy diet is essential because of the strenuous treatment schedule, chemotherapy, or any surgery that they might have to undergo. These can have a deep impact on the immune system.

People with renal cancer often lose their appetites or their taste for certain foods might change. They must consume a healthy and well-balanced diet to fight the symptoms of this disease. The nutritional requirements depend on the treatment process and the stage of cancer. There are certain foods to eat and certain foods to avoid with renal cancer.

Foods to eat with renal cancer

• Fruits and vegetables
  People with renal cancer should eat lots of fruits and vegetables as they are high in soluble fiber and provide vitamins and minerals. They also help lower cholesterol levels and control blood sugar.
• Whole grains and starch
  Whole grains and starchy foods are essential for people suffering from renal cancer. Starchy foods, such as whole-wheat bread, brown rice, and whole-wheat pasta, are great sources of energy. These foods also contain high fiber, iron, and vitamin B.
• High-calorie foods
  People undergoing treatments for renal cancer tend to lose weight. It is necessary to consume high-calorie and high-protein foods, such as peanut butter, milkshakes, sauces, gravies, meats, cheeses, and whole milk to keep them strong and healthy.

Foods to avoid with renal cancer
Certain foods can increase the risk of renal-related complications. It is necessary to eat the following foods in moderation or avoid them altogether.

• Foods high in salt
  Salt can interrupt the fluid balance and lead to high blood pressure. Foods to avoid with renal cancer are processed, canned food, salty snacks, and deli meats as they are high in sodium.
• Foods high in phosphorus
  Phosphorous, a chemical component, is important to maintain bone strength. But, it may build up in the bloodstream and cause symptoms such as itching and joint pain. High-phosphorus foods such as seeds, nuts, beans, and processed bran cereals should be avoided.
• Excessive water
  Over hydrating may also cause problems for people with renal cancer as their body is unable to absorb excess fluid. Though everyone needs to drink plenty of water, people with cancer patients should not consume liquids in excessive amounts.

Renal cancer treatments can weaken the immune system. It is necessary to have a balanced, nutritious diet that helps you to feel stronger, healthier, and energetic. The foods to avoid with renal cancer, which are mentioned above, should be noted for your safety. Raw foods such as sushi, shellfish, and vegetable sprouts should also be avoided.
