For people receiving treatment for kidney cancer, proper nutrition is the first step in managing, as cancer treatments such as surgery and others might take a toll on the well-being of your body. A balanced diet is hence the fuel to help prepare ourselves to cope with the symptoms and side effects of the treatment.
Know which foods you should prefer, what to eat more of, and the dietary changes you could expect during the course of the treatment.
What to Eat
Plenty of Fruits and Vegetables
These are rich in antioxidants, vitamins, and fiber, which help boost the immune system and aid digestion. Choose a variety of colors to get a broad spectrum of nutrients. Wash them thoroughly before consumption.
Starchy Foods
Include whole grains like brown rice, oats, quinoa, and whole wheat roti. These provide sustained energy and are rich in fiber, which helps maintain bowel regularity.
Fibre
Adequate fiber from fruits, vegetables, and whole grains helps prevent constipation, a common side effect of pain medications and reduced physical activity. However, if you have specific kidney-related dietary restrictions, consult your doctor before increasing fiber intake.
Unsaturated Fats
Choose healthy fats from sources like olive oil, avocados, nuts, and seeds. These fats support heart health and help absorb fat-soluble vitamins.
Proteins
Protein is essential for healing and maintaining muscle mass. However, cancer treatment may decrease the potential functioning of the kidneys, especially if one of the kidneys had to be removed. Consuming high-protein diets will require the kidneys to work harder to remove urea, a waste product from protein breakdown.
To know the right amounts and types of protein to include in your diet, it is recommended to speak to a nutritionist or doctor. Opt for lean sources like eggs, fish, skinless poultry, tofu, and legumes in moderation.
Saturated Fats
Limit foods high in saturated fats such as red meat, butter, ghee, and full-fat dairy. These can increase the risk of heart disease, which is a concern for patients with compromised kidney function.
Fluids
Staying hydrated is crucial, but fluid intake may need to be adjusted based on your kidney function. If you have one kidney or reduced kidney function, your doctor may advise limiting fluids. Always follow medical guidance on daily fluid intake.
How to Manage Common Side-Effects
The side effects from your cancer treatment greatly influence how you eat. Here are some common problems and tips to overcome them:
Poor Appetite
You might not feel like eating during cancer treatment due to loss of appetite. Still, it is very important to get the nutrition you need.
- Eat small, frequent meals throughout the day.
- Choose high-calorie, high-protein foods like cheese, eggs, and nut butters.
- Try smoothies, milkshakes, or soups if solid food is unappealing.
- Eat in a pleasant environment and consider eating with family or friends.
Nausea
Nausea can make eating difficult. Try these tips:
- Eat dry, bland foods like toast, crackers, or rice.
- Avoid strong-smelling or greasy foods.
- Sip ginger tea or lemon water.
- Rest with your head elevated after eating.
Constipation
Caused by painkillers, dehydration, or inactivity.
- Drink plenty of fluids (as allowed).
- Eat fiber-rich foods like oats, apples, and spinach.
- Stay physically active with light walking.
Food Safety
Cancer treatment can weaken your immune system, making you more prone to infections. Practice good hygiene when preparing meals:
- Thoroughly wash all vegetables, fruits, and other raw foods.
- If including meat, cook it thoroughly. Meats should not be pink, and eggs should not be runny.
- Refrigerate leftovers immediately if you plan to use them later.
- Avoid eating food from outside; home-cooked food is preferred.
NOTE: It is always better to speak to a clinical nutritionist or dietitian regarding the components of your diet, as everyone has a different condition. Other existing diseases must be considered before recommending a diet plan.
