A nutritious and balanced diet plays a therapeutic role for cancer patients. During cancer treatment, the body undergoes several changes—lower immunity, fatigue, digestive issues, weight loss, or weight gain. Eating the right foods helps strengthen immunity, provides energy, supports tissue repair, and reduces treatment complications.
Helps maintain a healthy weight
Reduces weakness and fatigue
Improves immunity against infections
Supports healing and recovery
Enhances the body’s response to treatment
Minimizes side effects like nausea, constipation, or appetite loss
Improves overall quality of life
Dr. Ruchir Bhandari recommends a tailored diet plan based on a patient’s type of cancer, treatment phase, and nutritional deficiencies.
Below are detailed, practical, and easy-to-follow diet guidelines recommended by Dr. Ruchir Bhandari:
Cancer and its treatment may weaken the immune system. Therefore, immunity-enhancing foods must be a regular part of the diet.
Fresh fruits like oranges, papaya, strawberries, apples, pomegranate
Vegetables like spinach, broccoli, carrots, capsicum, beetroot
Whole grains such as oats, quinoa, millets
Nuts and seeds including almonds, walnuts, chia seeds, flaxseeds
Turmeric, ginger, garlic, and herbs
Green tea and herbal teas
These foods provide antioxidants, vitamins C, E, A, and minerals that protect the body from infections and inflammation.
During cancer treatment, the body requires more protein to repair tissues and maintain muscle strength.
Eggs
Fish & chicken (for non-vegetarians)
Paneer, tofu, and soy products
Lentils, legumes, and beans
Greek yogurt or curd
Peanut butter
Protein shakes (only under doctor guidance)
Dr. Bhandari emphasizes that protein intake should be consistent throughout the day to prevent weakness and muscle loss.
Healthy fats are necessary for maintaining energy levels and supporting cell function.
Olive oil
Mustard oil
Avocados
Chia seeds
Walnuts
Fatty fish like salmon (if allowed)
Avoid saturated and trans fats found in deep-fried and packaged foods.
Cancer treatments often cause dehydration, especially due to vomiting, diarrhea, or excessive sweating.
Drink at least 8–10 glasses of water
Include ORS or electrolyte-rich fluids
Coconut water
Fresh soups and broths
Herbal teas
Fruit-infused water
Avoid sugary drinks, packaged juices, and carbonated beverages.
Many cancer patients suffer from appetite loss, nausea, or bloating. Small portion meals given at regular intervals are easier to digest and help maintain energy levels throughout the day.
Breakfast
Mid-morning fruit
Lunch
Evening snack
Light dinner
Bedtime drink (warm milk or herbal tea)
This method supports digestion and prevents weakness.
Cancer treatment impacts the digestive system. Easily digestible foods reduce strain on the stomach and gut.
Porridge
Khichdi
Boiled vegetables
Upma or daliya
Mashed potatoes
Soft chapatis
Soups and broths
Spicy, oily, or very fibrous foods should be avoided if digestion is weak.
Different colors indicate different nutrients. A rainbow diet ensures complete nutrition.
Red: tomatoes, watermelon, apples
Green: spinach, broccoli, cucumbers
Yellow: mangoes, corn, bananas
Orange: carrots, oranges, sweet potatoes
Purple: blueberries, grapes, brinjal
These help fight inflammation, boost immunity, and support healing.
Highly processed foods contain harmful additives, preservatives, and unhealthy fats that may worsen inflammation.
Packaged snacks
Excess salt
Pickles
Fried food
Bakery items
Excess sugar
Aerated drinks
A clean and natural diet is highly beneficial for cancer recovery.
Cancer patients are more vulnerable to infections. Hence, food safety becomes extremely important.
Wash raw fruits and vegetables thoroughly
Store food properly
Avoid raw or undercooked meat
Do not consume stale food
Use clean utensils and filtered water
Ensure proper hand hygiene
Prioritize fresh, hygienic, and well-cooked meals.
Lifestyle plays an equally important role as diet in improving treatment results and maintaining emotional well-being. Below are lifestyle practices that Dr. Bhandari strongly recommends to patients.
Exercise helps reduce fatigue, boosts mood, and strengthens the body.
Morning or evening walks
Light stretching
Yoga
Deep breathing exercises
Low-impact aerobics
Patients should start slow and increase activity gradually based on stamina.
Fatigue is common during cancer treatment. Adequate rest helps the body recover.

Use a comfortable pillow and mattress
Good sleep enhances immunity and recovery.
Stress affects immunity and overall health. Patients must adopt calming practices.

Emotional health significantly supports physical recovery.
Dr. Bhandari strictly advises avoiding:

Chemical fumes
Polluted environments
These can weaken the immune system and interfere with treatment.
A strong emotional support system helps keep anxiety and depression away.
Spend time with family and trusted friends
Join cancer support groups

Routine check-ups help monitor progress, adjust treatment, and manage side effects. Dr. Bhandari emphasizes that patients should never skip follow-up appointments.
Good hygiene prevents infections and ensures overall well-being.
Regular bathing
Clean clothing
Sanitizing hands frequently
Oral care to prevent mouth sores
