Food, Nutrition & Cancer
A complete, India-specific guide to eating during cancer treatment — how your diet should change from prevention through chemotherapy and beyond, built around the foods already in your kitchen.
There is no single cancer diet. What you should eat depends on which treatment you are having, what stage of it you are in, and how you are tolerating it.
Most nutrition advice online is written for a Western kitchen. This guide is built around Indian home cooking — dal, khichdi, idli, curd rice, paneer, eggs, chicken, and fish — the foods already in your kitchen.
What most patients want to know before they start
- There is no single "cancer diet" — it depends on your treatment and its stage.
- A few principles hold throughout: adequate protein, adequate calories.
- Food safety and staying hydrated matter at every stage.
- Blood sugar control matters — ask your team if this applies to you.
- Your everyday Indian kitchen is usually your best resource, not a special diet.
- Under-eating during treatment leads to muscle loss, worse fatigue, and can affect how well you tolerate your schedule.
