Chemotherapy is a powerful tool in the fight against cancer. But while it targets cancer cells, it can also affect the healthy cells in your body—especially those in your digestive system. That’s why eating the right foods during chemotherapy is more important than ever.

In this blog, we’ll help you understand what to eat and avoid during chemo, how to manage side effects like nausea and fatigue, and how to make mealtime easier and more nourishing.

Why Nutrition Matters During Chemotherapy

Chemotherapy can cause several side effects like:

• Loss of appetite
• Nausea and vomiting
• Mouth sores
• Diarrhea or constipation
• Fatigue

Good nutrition helps by:

• Supporting immune function
• Maintaining muscle mass
• Improving energy levels
• Promoting faster recovery
• Reducing risk of infections

Even if you’re not feeling hungry, your body still needs fuel to heal.

What to Eat During Chemotherapy

Here are some chemo-friendly foods that are gentle, nourishing, and supportive of healing:

1. Protein-Rich Foods

Your body needs extra protein to repair cells and maintain muscle. Try:

• Soft boiled eggs
• Chicken or turkey (boiled or grilled)
• Fish (like salmon for omega-3s)
• Paneer or tofu
• Greek yogurt or curd
• Lentils, dals, and sprouts

Tip: Add protein powders (doctor-approved) to smoothies for an easy boost.

2. Whole Grains

These provide long-lasting energy and help prevent constipation:

• Brown rice
• Whole wheat rotis
• Oats
• Quinoa
• Dalia (broken wheat)

3. Fruits and Vegetables

Choose low-acid, easy-to-digest fruits and well-cooked vegetables:

• Bananas, papayas, melons
• Applesauce
• Boiled carrots, pumpkin, bottle gourd
• Spinach or methi (well-cooked)

Eat the rainbow! It gives your body a mix of vitamins and antioxidants.

4. Healthy Fats

Support energy levels and absorb fat-soluble vitamins:

• Avocado
• Olive oil
• Flax seeds
• Nuts and nut butters (if not causing mouth sores)

5. Hydration Helpers

Chemotherapy can cause dehydration. Sip on:

• Coconut water
• Homemade soups and broths
• Buttermilk or chaas
• Herbal teas (like ginger or chamomile)
• ORS (oral rehydration solution) if prescribed

Foods to Avoid During Chemotherapy

These can cause dehydration and interfere with medications.

Bonus Tips to Manage Chemo Side Effects

• Nausea: Ginger tea, dry toast, small frequent meals
• Mouth sores: Eat soft, bland foods like khichdi, mashed potatoes, and cold curd
• Diarrhea: Stick to low-fiber foods like white rice, bananas
• Constipation: Drink more fluids, add soaked raisins or figs to your diet
• Fatigue: Plan meals ahead, ask for help, eat energy-dense snacks

Takeaway Message

During chemotherapy, food becomes more than just fuel—it becomes part of your healing journey. Focus on simple, wholesome, and soothing foods that keep your body strong and your spirits up. If you’re unsure, work with a clinical nutritionist or oncology dietitian to create a customized plan.
