What to Eat During Chemotherapy — A Guide for the Indian Kitchen

Outside food carries a higher infection risk when your immune counts are reduced, because you have less control over preparation hygiene. During the weeks when your counts are at their lowest — usually the first one to two weeks after each cycle — home-prepared food is the safer choice. Ask your team whether they have given you specific neutropenic precautions, because the level of caution depends on which drugs you are receiving and how low your counts actually drop.

There is no single amount that applies to everyone, and your team may give specific guidance based on which drugs you are receiving — some chemotherapy drugs need more flushing through the body than others. Signs you may not be getting enough fluid include darker-than-usual urine, dizziness, or passing much less urine than usual. Coconut water, buttermilk, and diluted juice all count toward your fluid intake. If vomiting is stopping you from keeping fluids down, call your team rather than trying to manage at home.

Loss of appetite is very common during chemotherapy and usually varies through the cycle — worse in the days immediately after treatment and better as your body recovers before the next cycle. If it has been severe or lasted throughout a cycle without improvement, mention it at your next visit or sooner if eating has stopped altogether. There are medicines that can help with appetite, and a dietitian can suggest foods that are easier to get down even when nothing sounds appealing.

No food or diet has been shown to make chemotherapy more or less effective. Claims that a particular diet treats or fights cancer are not supported by current evidence from ASCO, ESMO, or ICMR. What nutrition does affect is how well your body tolerates treatment and recovers between cycles — which is the practical reason it matters. Some extreme elimination diets can worsen nutritional depletion and make treatment harder to complete, so ask your team before making any major dietary change.

Yes — taste changes are a recognised side effect of many chemotherapy drugs and usually improve after treatment ends. Cold or room-temperature food is often more tolerable than hot food when this happens. Some people find metallic taste is reduced by using glass or stainless steel utensils rather than metal ones. If taste changes are making it very hard to eat anything at all, tell your team — a dietitian can suggest alternatives more likely to be tolerable during treatment.
