How should I eat during chemotherapy?  Entry from Alexandra Rothwell, MPH, RD, CSO, CDN

As an oncology nutritionist, I meet with people throughout the stages of treatment, recovery, and survivorship. The relationship between food and cancer is an ever-developing and popular field, and because of this, the people I meet with tend to have many questions. The following are a few of the most common questions I’m asked.

Having a chemotherapy regimen prescribed is an incredibly daunting experience, and I’ve noticed that patients are often left with practical questions about leading their day-to-day lives during treatment periods. Amongst these concerns: do I need to change my diet? The answer to this question depends largely on the type of cancer being treated and the regimen prescribed, as diet changes should correspond with whichever treatment side effects are expected. My basic recommendation is to follow a regular, healthy diet, and manage nutritionally relevant side effects as they arise. To be prepared, it’s always a good idea to meet with a registered dietitian before treatment to determine whether you need to follow a particular diet right way (neutropenic, for example), learn some simple diet alterations for potential issues, and get written material to bring home with you. (You can also use this site to have a few good recipe ideas on hand.) I typically recommend following a bland/simple diet for one or two days leading up to and following infusion. (Most chemotherapy regimens have potential gastrointestinal side effects, such as nausea, diarrhea, or constipation, and eating a bland diet for the days surrounding infusion can help to lessen the extent of these effects.) Similarly, a tip I’ve learned from patients is to avoid favorite foods on the day of infusion. This helps to deter the formation of any negative associations with foods that you love to eat.

Over the past several years, cancer treatments and medicinal management of side effects have really been optimized, and sometimes, people are able to get through these treatments without feeling particularly ill or needing to change their diet at all. For this reason, I encourage patients to decrease anticipation of negative side effects. Not uncommonly, anticipation alone can cause the side effect (“anticipatory nausea” is a real thing). Sometimes too, an expectation of poor appetite or weight loss leads to overeating and unhealthy weight gain. (Interestingly, for some cancers and their treatments, it’s more common to gain weight than to lose it.)

It might be helpful to think of treatment periods as a time when you want to give yourself the best care possible – in a way, you want to create a spa-like environment for yourself. Recruit friends and family members to help. Give yourself nourishing, healthy, and comforting foods, exercise gently and regularly, get plenty of sleep, rest when fatigued, and try to rid yourself of burdensome stressors. For diet, I recommend a plant-based or Mediterranean style: rich in non-starchy vegetables and fruit, moderate but consistent amounts of healthy fats, moderate to limited intake of good quality animal products, and limited amounts of starch.

  • Hi bigleg. As you will notice in the subject line, this is an entry from Alexandra Rothwell. She is an oncology nutritionist who volunteers to write blog posts on our site at cookforyourlife.org.

    I repost our blog to healthunlocked as a way to spread our helpful information to people touched by cancer, and to others who find our advice useful.

    Thank you for the advice about the series. We have heard great things and some of our staff recommends it as well!

  • Our site absolutely does include fat in recipes. We make no restrictions unless a side-effect of cancer treatment creates that necessity. Our recipes are about feeling and being well, and aiding in the treatment of those touched by cancer. We actually recommend good fats as a necessary component of a healthy diet.

  • Hi bigleg. That's a great point, and something we've been working on adding to our menu bar. We are undergoing a full website redesign which includes Fat as an ingredient next to Proteins, vegetables, etc.

    However, we have written about all kinds of fats and you can find those by clicking "Pantry Basics" in the menu bar. Thanks for your input!

  • If the course of cancer is the food we eat and the environment we live in as an oncology nutritionist what do you suggest on food intake to avoid cancer?

    Last year in Singapore I discussed food for a stomach cancer person with an oncology nutritionist who had the cancer removed. Very interesting!

  • Hi bala, our website cookforyourlife.org deals with this a bit differently. Because our focus is on treatment rather than prevention, you can search recipes based on treatment type and side-effects caused by cancer treatment. Under the ingredients section, you can also search for articles written about certain foods and pantry basics.

    Hope that helps!
