Chemotherapy is one of the most utilized methods to treat cancer. This method destroys cells by targeting fast-dividing cells; unfortunately, it cannot distinguish between cancerous and healthy cells. Chemotherapy impacts healthy cells of all kinds in the body, specifically those lining the GI tract, oral cavity, and immune cells.
It is for these reasons that patients undergo side effects of nausea, anorexia, fatigue, oral lesions, weight loss and the like. Nutrition is vital in overcoming the negative side effects and regaining health and strength to heal.
A well-planned diet during chemotherapy can help maintain body weight, preserve muscle mass, reduce the risk of infection, and improve overall quality of life.1 And it’s also great news for Indian patients; our food culture provides so many nurturing, soothing and healing choices to cater to chemotherapy recovery.
Why Nutrition Matters During Chemotherapy
Cancer and its treatment increase the body’s demand for energy and nutrients. Malnutrition is reported in 40–80% of cancer patients and is associated with poorer treatment outcomes, reduced tolerance to chemotherapy, and increased complications.2 Good nutrition can allow the body to heal damaged tissues, fight off illness and provide the patient with less fatigue to cope with their chosen treatment plan.
The goal of nutritional support during chemotherapy is not weight loss or strict dieting. It is about eating enough of the right foods to keep the body strong.
Key Nutritional Needs During Chemotherapy
During chemotherapy, the body requires higher amounts of certain nutrients:
- Protein: Essential for tissue repair and immune function. Protein needs are increased to 2–2.0 g per kg of body weight per day during cancer treatment.3
- Calories: Intake adequate in calories can prevent loss of weight and can prevent loss of muscle. Maintaining muscle and weight can also prevent the worsening of treatment intolerance.
- Antioxidants and Micronutrients: Whole foods can provide effective vitamins and minerals as well as be good sources of antioxidants. Inflammatory response can be moderated with good immune defense as a result of fruits and vegetables with higher amounts of vitamins A, C, and E, zinc, and selenium. This can be preferable to high dose vitamin and mineral supplementation during treatment.
- Fluids: Good hydration can also help in the management of nausea and help in the prevention of constipation. This is also important in helping the kidneys while ensuring the chemotherapy is able to be effectively metabolized within the body.
Indian Foods That Support Chemotherapy Recovery
The following foods, commonly found in Indian households, are particularly beneficial during chemotherapy:
-
Dal (Lentils and Legumes)
Moong dal, masoor dal, and toor dal contain easily digestible proteins. Moong dal khichdi combines rice and lentils and is a nourishing food for a chemotherapy patient. Lentils are a good source of iron and folate, both of which are depleted during treatment.5
-
Curd (Dahi) and Buttermilk (Chaas)
Plain, homemade curd is a rich source of protein and probiotics. Chemotherapy can disrupt the gut microbiome, leading to diarrhoea or constipation. Probiotics help restore gut health and improve digestive comfort.6 A mix of roasted cumin and buttermilk is creamy, refreshing, and light on the stomach.
-
Turmeric (Haldi)
Curcumin, which is found in turmeric, has been extensively studied for its ability to act as an anti-inflammatory agent and also as an antioxidant. Curcumin has also been studied to help in treating cancer.7 A pinch of haldi in either warm milk or dal would easily fulfill the requirements of including haldi in the daily diet. Warning: high-dose curcumin should not be taken without the advice of a doctor.
-
Khichdi and Soft Rice Preparations
Khichdi is a wholesome meal which provides all the necessary nutrition elements like carbohydrates, proteins, and some fat in a very easily digestible form. It can even be enhanced by adding Ghee in order to make it more calorie-rich or using veggies to add vitamins to it. Patients who suffer from mouth ulcers or problems while swallowing find the well-cooked Khichdi very soothing.
-
Coconut Water and Homemade Soups
The Coconut water is a great natural electrolyte-rich drink which assists in hydration and restores the loss of minerals in case of vomiting and diarrhoea.8 Tomato soup, lauki soup, and spinach soups prepared at home provide great nutrition.
-
Banana, Papaya, and Soft Seasonal Fruits
Bananas that have ripened are easy on the stomach, high in potassium, and can be eaten comfortably even if there are ulcers in the mouth. Papayas help in digesting food, provide vitamin C, and contain folic acid. Soft fruits should be preferred instead of raw fruits and those with peels.9
-
Ghee (Clarified Butter)
For people having difficulty losing weight, ghee acts as an excellent source of fat calories. Just one teaspoon of ghee in dal, rice, and khichdi can provide enough calorie boost while not adding much volume to the amount of food consumed, especially when appetite is low.
Foods to Use with Caution
Chemotherapy reduces immunity. Some types of food can have more chances of bacteria infection and need to be either avoided or prepared with extra care:
- Raw sprouts, salads, and fruits that haven’t been peeled
- Unpasteurized milk and dairy products
- Vendor food and street food in general
- Too spicy and oily food since it might cause more nausea and indigestion
Practical Tips for Managing Eating During Treatment
- Consume small meals every 2 to 3 hours
- When in trouble, opt for warm, easy-to-swallow food
- Consume plenty of water, coconut water, chaas, and light soup
- Avoid eating favorite foods when nauseated because you might develop aversion towards it later
- Get help from a registered dietitian with creating a personalized meal schedule
Conclusion
Good nutrition is not a substitute for medical treatment but it is an essential part of the recovery journey. With thoughtful food choices, Indian patients undergoing chemotherapy can manage side effects more effectively, maintain their strength, and support their body through treatment. If you are unsure where to begin, a clinical dietitian can guide you with a plan that is practical, culturally appropriate, and tailored to your specific needs.
