When you have cancer, what you eat may not seem important. Cancer treatments and their side effects, and just having cancer can change the way you eat and how your body uses nutrients. It can be difficult for you to eat well.

Why should I eat healthy?

You’ll feel better during and after treatment if you eat healthy, cancer-fighting foods. Healthy eating also helps you heal. Some cancer treatments work better if you’re well-nourished and are getting enough calories and protein, according to the American Cancer Society.

Healthy eating can relieve common eating problems. If you have nausea and vomiting from chemo, for example, you’ll feel better if you:

  • Eat small meals and snacks 6 to 8 times a day.
  • Eat dry foods, like crackers, toast, dry cereals, or breadsticks.
  • Eat foods and drink liquids at room temperature.
  • Avoid foods with strong odors.
  • Avoid hot, spicy, greasy, fried, high-fat, or very sweet foods.

Other eating problems that healthy eating can help relieve include:

  • Changes in appetite and weight loss
  • Constipation
  • Diarrhea
  • Fatigue
  • Sore mouth or throat
  • Unwanted weight gain

Which foods will help me fight cancer?

Whole foods are packed with cancer-fighting phytochemicals and nutrients. They include vegetables, fruits, whole grains, nuts, and legumes. Try to eat:

  • Lots of vegetables and fruit
  • Moderate amounts of whole grains and plant protein, like nuts, beans, lentils, tofu, and tempeh
  • Moderate portions of fish, poultry, lean meats, and non-fat or low-fat dairy foods

The American Cancer Society suggests eating at least 2 1⁄2 cups of vegetables and fruits a day, including dark-green and deep-yellow vegetables and citrus fruits. Soup is an easy way to eat more vegetables. You can make enough for a few meals and freeze it.

How can I eat healthy when I’m too tired to cook? 

Try these ready-to-eat, high-calorie, high-protein foods:

  • Avocado
  • Canned tuna or chicken
  • Cheese
  • Dried fruits
  • Guacamole
  • Hard-boiled eggs
  • Hummus on whole-grain crackers or bread
  • Liquid nutritional supplements
  • Ice cream (low sugar)
  • Nuts
  • Peanut butter and almond butter (natural with no sugar added)
  • Pudding (low sugar)
  • Yogurt

Should I buy organic vegetables and fruits?

Organic vegetables and fruits, grown without pesticides and synthetic fertilizers, are safer than conventionally grown food and often more nutritious. But organic food is expensive.

Buy organic when it matters most. Follow the Environmental Working Group’s annual Shopper’s Guide to Pesticides in ProduceTM:

  • The Dirty DozenTM list highlights what you should buy organic: the vegetables and fruits with the highest levels of pesticide residues.
  • The Clean FifteenTM list highlights foods with no pesticide residues or minimal amounts of pesticide residues. You don’t need to spend extra money on the organic versions of these foods.

How can I make healthy food taste good?

Healthy eating can be delicious too. Start with ingredients rich in the nutrients that you need to thrive. Use herbs and spices to add flavor to food and help fight cancer. For example, add:

  • Garlic, red pepper flakes, and olive oil to spinach
  • Sesame, ginger, and garlic to red cabbage and kale

Other Recommendations for Healthy Eating

The American Cancer Society also recommends:

  • Limiting high-fat foods, especially those from animal sources. Choose low- or no-fat dairy products. Bake or broil foods to reduce fat.
  • Limiting salt-cured, smoked, and pickled foods

The American Institute for Cancer Research recommends:

  • Avoiding processed meats
  • Limiting red meat (like beef, pork, and lamb) to three portions per week (12-18 ounces)
  • Not drinking alcohol

Your cancer care team can help you customize your strategies for healthy eating based on your needs.
