Nutrition Tips During Cancer Treatment by Oncologist

 Cancer treatment can be physically and emotionally draining. During this challenging journey, one often-overlooked yet crucial aspect of healing is nutrition. Maintaining a healthy, balanced diet during cancer therapy not only supports the body’s strength and immunity but also improves treatment outcomes and enhances quality of life.

At Action Cancer Hospital, experienced Medical Oncologists in Delhi emphasize the importance of tailored nutrition strategies for every patient, depending on their type of cancer, treatment plan, and individual nutritional needs.

In this blog, we bring you expert-approved nutrition tips during cancer treatment, directly from leading oncologists and nutritionists.




Why Nutrition Matters During Cancer Treatment

Cancer treatments like chemotherapy, radiation, immunotherapy, and surgery can cause various side effects such as:

  • Loss of appetite

  • Nausea and vomiting

  • Diarrhea or constipation

  • Taste changes

  • Weight loss or gain

  • Fatigue and weakness

These side effects can lead to malnutrition, further weakening the body. A good nutrition plan helps:

  • Improve immune function

  • Maintain muscle strength

  • Promote faster healing and recovery

  • Increase energy levels

  • Reduce complications from treatment

  • Enhance tolerance to therapy

That’s why oncologists at Action Cancer Hospital work closely with dietitians to guide patients through personalized nutrition plans.


1. Eat Small, Frequent Meals

Loss of appetite is a common issue during cancer treatment. Instead of sticking to three large meals a day, try eating 5–6 small meals spaced throughout the day. This helps:

  • Maintain calorie intake

  • Prevent nausea

  • Keep energy levels stable

Tip: Keep healthy snacks handy like roasted nuts, yogurt, or boiled eggs.


2. Stay Hydrated

Dehydration can worsen fatigue and affect kidney function, especially during chemotherapy. It is vital to drink at least 8–10 glasses of water daily, unless otherwise advised by your doctor.

Recommended fluids:

  • Coconut water

  • Herbal teas

  • Vegetable broths

  • Oral rehydration solutions

Avoid caffeinated or sugary drinks as they may worsen dehydration.


3. Focus on Protein-Rich Foods

Protein is essential for healing tissues and maintaining muscle mass. Include a good source of protein with every meal.

Protein-rich foods include:

  • Eggs

  • Paneer (cottage cheese)

  • Chicken or fish (if non-vegetarian)

  • Lentils and legumes

  • Tofu or soy products

  • Milk and dairy

Patients undergoing radiation or chemotherapy are especially advised by Medical Oncology to increase protein intake to help repair damaged tissues.


4. Incorporate Fruits and Vegetables

Colorful fruits and vegetables provide antioxidants, vitamins, and fiber. These help:

  • Reduce inflammation

  • Boost the immune system

  • Improve digestion

Top picks:

  • Berries (rich in antioxidants)

  • Carrots and spinach (beta-carotene)

  • Tomatoes (lycopene)

  • Broccoli and cauliflower (cruciferous vegetables)

Important: Wash thoroughly or steam lightly to kill any bacteria, especially when immunity is low.


5. Limit Processed and Sugary Foods

While cravings are normal, try to avoid excessive intake of:

  • Refined sugars

  • Processed snacks

  • Fried and oily foods

  • Carbonated drinks

These can lead to weight gain, inflammation, and interfere with treatment.

Oncologists at Action Cancer Hospital often warn against "empty calories" and recommend replacing them with nutrient-dense options.


6. Manage Taste Changes

Cancer treatment can alter your sense of taste and smell. If food starts tasting metallic or bland:

  • Use herbs and natural spices (like ginger, lemon, basil)

  • Marinate meats or vegetables to enhance flavor

  • Use plastic utensils instead of metal

  • Try cold or room-temperature foods if warm food causes nausea


7. Combat Nausea Naturally

To fight nausea caused by chemotherapy:

  • Eat dry crackers or toast in the morning

  • Sip on ginger tea or peppermint tea

  • Avoid strong-smelling or greasy foods

  • Eat slowly and in a calm environment

Consult a Medical Oncologist in Delhi for anti-nausea medications if it becomes severe.


8. Include Whole Grains for Energy

Whole grains are a great source of complex carbohydrates, providing sustained energy throughout the day.

Good options:

  • Brown rice

  • Oats

  • Whole wheat rotis

  • Quinoa

  • Barley

Avoid refined flour (maida), which offers little nutrition.


9. Watch for Food Safety

Cancer treatments often weaken the immune system. Follow strict food safety practices to avoid infections:

  • Wash fruits and vegetables thoroughly

  • Avoid raw meat, eggs, or seafood

  • Eat freshly cooked meals

  • Store leftovers properly

  • Reheat food until steaming hot

At Action Cancer Hospital, dietitians educate patients about safe cooking practices, especially during periods of low immunity.


10. Customize Your Diet Plan

There is no one-size-fits-all diet for cancer patients. Your nutritional needs may vary based on:

  • Type of cancer

  • Stage of treatment

  • Weight changes

  • Digestive issues

  • Pre-existing conditions (like diabetes or kidney issues)

That’s why consulting a Medical Oncologist in Delhi, along with a registered dietitian, is the best way to get a personalized meal plan.


Bonus Tips from Oncologists at Action Cancer Hospital

  • Before chemotherapy sessions, eat a light meal to avoid nausea.

  • During radiotherapy, consume foods rich in vitamins A, C, and E for skin repair.

  • Post-surgery, opt for easy-to-digest soft foods like khichdi, soups, or fruit purees.

  • For weight loss, use high-calorie shakes or smoothies with bananas, peanut butter, and milk.


Conclusion

Proper nutrition during cancer treatment plays a key role in how well you respond to therapy and recover. While treatments focus on fighting the disease, a balanced diet fuels your body to withstand the process.
