Nutrition During Chemotherapy

Woman drinking glass of water.During chemotherapy, the energy provided by a healthy diet can help you rebuild normal cells. It can also help you keep up your strength and fight infection. As a result, you may feel better and be more able to cope with side effects. Ask your doctor about your nutrition needs.

Drink plenty of fluids

  • Fluids help the body produce urine and decrease constipation. They help prevent kidney and bladder problems. They also help replace fluids lost from vomiting and diarrhea.

  • Try water, unsweetened juices, and other flavored drinks without caffeine. They flush toxins from the body.

Get enough calories

  • Calories are fuel. The body uses this fuel to perform all of its functions, including healing.

  • It’s OK to be lean, but be sure you are not underweight. If you are, try eating more calories.

  • Eat calorie-dense foods such as avocados, peanut butter, eggs, and ice cream.

  • If you need extra calories, add butter, gravy, and sauces to foods (if tolerated).

  • If you don’t need the extra calories, try to limit foods that are fried, greasy, or high in fat or added sugar.

Eat protein, fruits, and vegetables

  • Protein builds muscle, bone, skin, and blood. It helps your body heal and fight infection. It also helps boost your energy level.

  • Good protein choices include yogurt, eggs, chicken, lean meats, beans, and peanut butter.

  • Fruits and vegetables are full of important vitamins, minerals, and fiber to help your body function properly.

  • Try to eat a variety of vegetables, fruits, whole grains, and beans.

  • Ask your doctor about instant protein powder or other supplements.

Eating right during treatment

Side effects may make it a little harder to eat well on some days. The following tips will help you continue to get the nutrition you need:

  • Be open to new foods and recipes.

  • Eat small portions often and slowly.

  • Have a healthy snack instead of a meal if you are not very hungry.

  • Try eating in a new setting.

  • Physical activity, such as walking, can help increase your appetite. Try to be active for at least 30 minutes each day.

  • Boost your diet by getting the vitamins and minerals you need from fruits, vegetables, and whole grains.

  • If you live alone and are not up to cooking, ask your healthcare provider about Meals on Wheels or other outreach programs.

  • Sometimes, it is best to follow your appetitie. Eat when you are hungry, but when you ar enot, forcing yourself to eat can make you feel bad, nauseated, or even cause you to vomit.
