8 Diet and Nutrition Tips During Cancer Treatment from the Best Oncologist in Pune

Navigating cancer is a life-changing journey, not only for patients but also for their families and caregivers. During this challenging time, taking care of your body with the right nutrition becomes more important than ever. Food is not just a source of energy—it is essential for building strength, boosting immunity, managing side effects, and speeding up recovery while undergoing treatment.

Malnutrition affects 20-70% of cancer patients globally. Good nutrition isn’t just a theory—it’s proven. Following a balanced, healthy diet can help those undergoing cancer treatment tolerate therapies better and improve their overall quality of life. Let’s explore top 8 diet and nutrition tips during cancer treatment from the best oncologist in Pune, designed to guide and support patients at every step of their journey.

Why Nutrition Matters in Cancer Care

Did you know that what you eat directly affects how your body handles cancer treatment? Nutrition fuels your immune system, helps your tissue repair, and gives you the energy you need to fight back against cancer and regain your health. Leading doctors stress the importance of nutrition during treatment. Good nutrition can help you maintain your strength, prevent infections, and recover faster—key factors for anyone undergoing chemotherapy, radiation, or surgery. Treatments can be tough on the body, often causing side effects like nausea, fatigue, taste changes, or loss of appetite. The right foods can help you manage these challenges, making the journey smoother. With this foundation, let’s explore eight easy-to-follow diet and nutrition tips.

8 Diet and Nutrition Tips For Cancer Patients

1. Prioritize Protein-Rich Foods

Proteins are the building blocks your body needs for tissue repair, immune function, and to fight infections. Chemotherapy and radiation can break down your muscles and tissues, but eating enough protein supports healing and muscle maintenance.

What to eat: Eggs, fish, lean chicken, turkey, dals, beans, lentils, and tofu. Even milk, paneer, and yogurt are excellent protein sources. Including protein in every meal helps you keep your strength up—especially important if you’re losing weight.

If there are days your appetite is low, try adding a scoop of protein powder to your soups or smoothies for an extra boost. Mixing dals and grains also increases the protein quality of the meal. If you face difficulty chewing, try soft foods like well-cooked dals, scrambled eggs, or curd. Always consult your nutritionist or doctor before introducing supplements.

2. Stay Hydrated

Water is your best friend. Treatments may cause dehydration or leave you feeling tired. Drinking enough fluids can prevent headaches, constipation, and fatigue. Try water, clear soups, herbal teas, coconut water, or homemade fruit juices (without too much sugar). Broths are gentle on upset stomachs and help keep you hydrated. Carry a water bottle so you remember to sip throughout the day.

Sometimes you may not feel thirsty, but your body still needs fluids—set reminders or keep a colorful bottle nearby as a visual cue. If plain water tastes bland, infuse it with fresh fruit slices or herbs like mint for a gentle flavor. Dehydration can also make side effects worse, so make hydration part of your routine, even taking small sips often throughout the day. If you have vomiting or diarrhoea, increase your fluid intake as advised by your doctor.

3. Eat Small, Frequent Meals

Loss of appetite or nausea is common during treatment. Instead of forcing yourself to eat three big meals, try having smaller, more frequent meals. This approach is less overwhelming and can help maintain energy levels. Good snacks include: Fresh fruit, nuts, cheese, yogurt, whole-grain crackers, or energy balls made from dried fruit and seeds. Listen to your body—eat what feels right at that time.

You might find food more appealing when it’s nicely plated or served at room temperature, which can reduce smells that might trigger nausea. If mornings are harder, eat your biggest meal when you feel best during the day. Don’t hesitate to ask family or caregivers for help preparing easy-to-grab nutrient-rich snacks. Keep a snack box handy for between-meal hunger pangs—even a few bites at a time are helpful.

4. Include a Variety of Fruits and Vegetables

Fruits and vegetables provide antioxidants, important vitamins, and fiber. They help the body fight infections, repair cells, and regulate digestion. Oncologists often recommend a “rainbow diet”—filling your plate with colorful fruits and veggies to get a range of nutrients.

Tip: Choose seasonal, locally available fruits and vegetables. Wash them thoroughly to remove pesticides and reduce infection risks, especially important when immunity is low.

Blend fruits into smoothies or add finely chopped veggies to dals and parathas if you have trouble chewing. Cooking vegetables slightly can make them easier to digest without losing too many nutrients. If raw salads are discouraged due to low immunity, opt for steamed or cooked alternatives. The goal is to enjoy different colors—each color offers unique benefits your body needs while healing.

5. Limit Processed and Sugary Foods

Processed snacks, sugary drinks, and ready-made foods can weaken your immune system and fuel inflammation, making it harder for your body to heal. Reading food labels can help you spot hidden sugars and unhealthy fats. Home-cooked meals allow you to control ingredients and avoid preservatives. Craving sweets? Try dates, figs, or a homemade fruit salad for a healthier treat. Gradually reducing processed foods will not only support your immune system but can also help manage treatment side effects better.

Choose instead: Whole grains (like brown rice, oats, whole wheat bread), fresh fruits, and wholesome homemade meals. Limit biscuits, chips, colas, packaged juices, and sweets.

6. Manage Side Effects with Tailored Foods

Side effects differ from person to person. Adjusting your diet can help you feel better:

• For nausea: Sip ginger tea or eat plain dry crackers.
• For mouth sores: Opt for soft foods like pureed soups, smoothies, curd, soft rotis, or rice.
• For constipation: Go for fiber-rich options—whole grains, fresh fruits like papaya, prunes, figs, and drink more water.

If you experience diarrhea, avoid high-fiber or spicy foods and consult your doctor for suitable options. Keeping a food diary may help you identify triggers for discomfort so you can adjust your meals. Always inform your nutritionist or doctor about persistent symptoms—they can personalize your eating plan for better comfort and relief. Remember: gentle, soothing foods can make mealtimes more pleasant during tough days.

7. Focus on Immune-Boosting Foods

Certain foods naturally help support your immune system, critical during treatment.

Include: Oranges, lemons, and guavas (rich in vitamin C); mushrooms, fatty fish, and egg yolks (vitamin D); leafy greens and nuts (zinc); and probiotic foods like curd or buttermilk. These foods can help reduce your risk of infections and promote faster recovery.

Try adding lemon juice to salads or sipping on a glass of chaas (buttermilk) between meals. For vitamin D, sunlight is also beneficial; consider short, safe exposure as recommended by your doctor. If you’re not able to eat certain foods, discuss safe alternatives or supplements with your healthcare team. A well-nourished body is better able to handle the demands of treatment and healing.
