It’s important to get enough nutrition before, during, and after your cancer treatment. Getting enough nutrition can help you:

  • Maintain your strength
  • Keep your weight stable
  • Fight infection
  • Have fewer side effects
  • Heal after surgery

Read through this resource at least once before your treatment. You may also want to use it as a reference during and after your treatment. You can use the links in the “Navigate this article” area to the right to help you find the information that’s most useful at different times during your treatment.

Clinical dietitian nutritionists are also available to help you plan your diet during and after treatment. They can help make sure you get enough nutrition. To make an appointment with a clinical dietitian nutritionist, call 212-639-7312 or ask a member of your healthcare team to help you.

About Your Nutrition During Treatment

It’s important to follow a well-balanced diet so you get enough nutrition during your treatment. This will help keep your weight stable and maintain your muscles and strength.

Your clinical dietitian nutritionist will write down your nutritional needs in the box below. Keep them in mind when planning your meals.

  • You need _______________ calories per day
  • You need _______________ grams of protein per day
  • You need _______________ ounces of fluid per day

Tracking your weight

Tracking your weight during treatment is important. Weigh yourself about every 3 to 5 days, or as often as your clinical dietitian nutritionist asks you to. It’s best to weigh yourself around the same time each day. Make sure you’re wearing the same amount of clothes each time and using the same scale.

It’s normal to lose weight during your treatment. Your clinical dietitian nutritionist will work with you to help keep you from losing too much weight. If you’re losing too much weight, or need help with your diet, make an appointment with a clinical dietitian nutritionist.

Side Effects During Treatment

Tips for managing common side effects

Taste changes or lack of taste

If you have taste changes or lack of taste:

  • Try adding marinades, herbs, or spices to your food. Don’t add these to your food if you also have mouth sores or painful swallowing.
  • If you have a metallic taste in your mouth, use plastic utensils and avoid drinking out of cans.
  • It’s best to limit or avoid some of your favorite foods during treatment. They may not taste as you remember them. This might make you connect these foods to negative thoughts in the future.

Mouth sores and painful swallowing

If you have mouth sores, painful swallowing, or both:

  • Try eating soft, bland foods. You can read about these in the “Soft and Bland Foods” section.
  • Avoid steaming hot foods and drinks.
  • Don’t eat acidic fruits (such as oranges, grapefruits, lemons, or limes) or drink acidic fruit juice.
  • Don’t eat spicy foods.
  • Don’t eat foods with rough textures, such as toast or crackers.
  • Rinse your mouth every 4 to 6 hours, or more often for comfort. Use 1 of the following liquids:
    • One quart (4 cups) of water mixed with 1 teaspoon of salt and 1 teaspoon of baking soda
    • One quart of water mixed with 1 teaspoon of salt
    • One quart of water mixed with 1 teaspoon of baking soda
    • Water
    • A mouthwash with no alcohol or sugar

To rinse, swish and gargle the liquid for 15 to 30 seconds, then spit it out.

If these tips don’t help your mouth pain or painful swallowing, tell your healthcare provider. They can prescribe a medication to help.

You can also ask your healthcare provider for a referral to a swallowing specialist. They can recommend foods and liquids that are safe and easy to swallow.

For more information about painful swallowing and mouth care during treatment, read the following resources:


If you feel too tired to make a whole meal, try eating foods that are ready-made or that cook quickly. You can also try single-serving items, such as yogurt, cottage cheese, hard boiled eggs, tuna salad, canned creamy soups, or a pre-cooked rotisserie chicken.

Decreased appetite

If you don’t feel hungry, try these tips:

  • Eat small meals often and avoid large, heavy meals. For example, have 6 smaller meals during the day instead of 3 large ones.
  • Eat foods high in calories and protein. Read the section “Increasing Your Calorie and Protein Intake” for more information.
  • Eat in a pleasant environment, such as in front of a window or another place you enjoy.
  • Eat with friends and family if you find it helpful.
  • Read the section “Making nutritional shakes to increase protein and calories” for ideas to get more nutrition.
  • If you’re having trouble eating enough, talk with a member of your healthcare team.

Thick mucus

If you have thick mucus in your throat:

  • Sip on clear liquids during the day. These can include water, non-acidic fruit juice, sports drinks, broth, Ensure® Clear, or Boost® Breeze.
  • Drink warm water or warm tea with honey.
  • If you don’t have mouth sores, try gargling with club soda.

Dry mouth

If your mouth is dry:

  • Choose soft, moist foods, such as watermelon, yogurt, and pudding. For more ideas, read the “Soft and Bland Foods” section.
  • Suck on ice pops.
  • Add gravies, sauces, applesauce, or other liquids to your foods.
  • Have a spoonful of warm soup or other liquid between mouthfuls of food.
  • Try foods made with gelatin, such as mousses or Jell-O®. They tend to slide down your throat more easily.
  • Always carry a bottle of water with you. You can also try carrying a small, clean spray bottle filled with water. Spray water in your mouth throughout the day to keep it moist.
  • Try eating sugar-free mints or lemon drops or chewing sugar-free gum to make more saliva.
  • Sip on fruit nectars such as pear, peach and apricot, and drink papaya juice.
  • Talk with your healthcare provider about trying an over-the-counter (not prescription) saliva supplement.
  • Avoid alcoholic drinks and drinks with caffeine.
  • Avoid mouthwashes that contain alcohol.
  • Avoid eating dry, starchy foods such as toast, crackers, or dry cereal.


Most healthcare providers will prescribe medication to treat nausea or keep it from happening. If you have nausea, you can also follow the guidelines below to help manage it.

  • Don’t eat spicy foods.
  • Don’t eat high-fat foods, especially fried foods, such as donuts, french fries, pizza, and pastries.
  • Avoid laying down right after you eat.
  • If the smell of food bothers you, try eating your food at room temperature or cold. Avoid foods that are too hot. They often have a stronger smell that can make nausea worse.
  • Eat small, frequent meals. For example, have 6 smaller meals during the day instead of 3 large ones.
  • Take your time eating and chew your food well to make it easier to digest.
  • Don’t drink large amounts of liquids at once. This will keep you from getting too full. Getting too full can make nausea worse.
  • Try sipping on ginger tea, ginger ale, non-alcoholic ginger beer, or sucking on candies containing real ginger. Ginger may be soothing and help with nausea.
  • Try eating low-fat, starchy foods. These foods may be less likely to make you feel nauseous. For example, try rice, white toast, crackers, cheerios, melba toast, or angel food cake.
  • Try eating salty foods, such as pretzels or saltine crackers.

Other treatment tips

  • It’s important to keep your mouth clean during your treatment. Brush your teeth regularly. Follow the guidelines in the resource Mouth Care During Your Cancer Treatment for other ways to help you take good care of your mouth.
  • If your doctor prescribed you medication for pain, nausea (feeling like you’re going to throw up), or both, you should talk to your doctor about the best time to take it. Some doctors recommend taking these medications before meals.

Feeding tube placement

If your side effects are keeping you from getting enough nutrition or putting you at risk of choking, you may need to have a feeding tube placed. A feeding tube can be placed during or after your treatment.

If you have a feeding tube, work with your clinical dietitian nutritionist, or Gastroenterology (GI) Nutrition doctor to make sure you’re getting enough nutrition and fluids. They will give you a diet to follow.

Increasing Your Calorie and Protein Intake

It’s important to eat enough calories and protein during your cancer treatment so you can maintain your weight. Remember that these are general tips. Everyone is different so it’s important to try the tips that work best for you.

  • Poultry, meat, eggs, beans, nuts and nut butters, and dairy products are all good sources of protein. You should try to choose foods that are high in protein in all your meals and snacks.
  • Nuts and nut butters, avocados, olive or canola oils, and whole fat dairy products are good sources of calories. Adding them to your diet can help you increase the number of calories you eat.
  • If you’re having trouble keeping your weight the same, choose drinks that have calories instead of water. Examples are fruit juices, fruit nectars, and liquid nutritional supplements, such as Ensure®.
    • If you have diabetes, talk with your doctor or clinical dietitian nutritionist before doing this. They may tell you to limit or avoid sugary drinks to help control your blood sugar.
  • It’s important to stay hydrated and drink a lot of fluids during and after your treatment. If you want to know how much fluid you should be drinking each day, talk with your clinical dietitian nutritionist.

Homemade nutritional shakes

Making shakes or smoothies is a great way to increase the number of calories and protein you get each day. Toward the end of your treatment, you may be only drinking shakes, depending on how you’re feeling.

The following chart has examples of different bases and mix-ins you can use to make shakes. You should choose one of the liquid nutritional supplements listed in the table below as a base and add in whatever mix-ins you’d like to increase your calories, if needed. If you prefer, you can drink the liquid nutritional supplements on their own.

Use this chart to keep track of how many shakes you’re drinking per day. Your clinical dietitian nutritionist will tell you how many servings of each you should have per day.

Nutrition Guidelines After Treatment

Even when your treatment ends, your side effects may get worse or continue for some time. To help with this, keep changing your diet as needed to make eating and drinking easier. It’s important to eat well and stay hydrated so your body can heal. To heal properly, your body will need more calories and protein. Some people will need to be on a liquid diet, soft diet, or both to get the nutrition they need. Keep drinking your homemade shakes or liquid nutritional supplements to help you meet your nutrition needs.

Start adding pureed or soft solid foods to your diet 1 month after your treatment has finished. You can start adding them earlier if you feel ready, and if your doctor tells you it’s okay. You can start by eating ¼ cup soft solid or puréed food at least 3 times per day. You should also take nutritional supplements to meet the rest of your nutrition needs. Talk with your clinical dietitian nutritionist if needed.

You can also continue to meet with your clinical dietitian nutritionist once your treatment is over.
