Nutrition and Cancer

Nutrition is important in both the prevention and treatment of cancer. That's why we have a clinical dietitian specializing in diet and cancer.  For more information, please call 859-260-4499.

Eating Tips for Cancer Prevention

The American Cancer Society advises everyone to help lower cancer risk by following these guidelines:

  • Choose most of the foods you eat from plant sources (grains, vegetables and fruit)
  • Limit intake of high fat foods/meats
  • Be physically active and maintain a healthy body weight
  • Limit intake of alcohol

Eating Tips for Patients with Cancer

Central Baptist Hospital's Cancer Care Center staff recommends that patients with cancer eat differently than they did before they were diagnosed. Cancer patients need to shift their focus away from healthy eating for prevention to increasing their intake of high calorie foods - especially foods that also provide protein, vitamins and minerals.

Taking in extra calories is important, because cancer cells use carbohydrate, protein and fat differently than normal cells, resulting in increased nutrient and calorie needs. Cancer cells can also send false chemical signals that cause loss of appetite. Finally, cancer treatment can alter the ability to ingest, digest and absorb food, as well as the ability to eliminate waste. For all these reasons, nutrition assessment is a key part of cancer care. Cancer patients should be evaluated to identify their individual nutrition needs.

Here are some tips for helping with some of the common eating problems cancer patients face:

Poor Appetite

  • Practice good mouth care.
  • Rest before meals.
  • Eat in a comfortable position in a relaxed, quiet place.
  • Don't drink a lot of fluid before and during meals.
  • Eat small meals 5-6 times a day.
  • Make the meal you can eat the best (often breakfast) your biggest meal.
  • Avoid bad odors.
  • Try to pick foods you like that have a lot of nutrition, like high protein shakes.
  • Increase movement/activity as much as you can.

Weight Loss (to increase calories)

  • Be sure to have snacks/supplements handy.
  • Use liquid supplements or shakes for the fluid you need to take medicine.
  • Try a variety of supplements, such as instant breakfast, to find those you like. IF TOLERATED ADD:
    • A tablespoon or two of milk powder.
    • Pasteurized egg substitute to shakes.
    • Carbohydrate powder.
  • Just one teaspoon of butter or margarine will add 45 calories to any food. Mix it into soups, vegetables, mashed potatoes, cooked cereals, rice batter for quick breads.
  • Add honey or extra sugar (white or brown) to cereal.
  • Use extra whipped cream, marshmallows, dry fruit or chopped nuts on top of desserts and in baked goods and puddings.
  • Try peanut butter as a spread on slices of apple, celery, pears, banana and other fruits.
  • Use sour cream, yogurt or blenderized cottage cheese on vegetables such as potatoes, beans, carrots, squash or as a dip for fruits and vegetables.

"Feeling Full" (early satiety)

  • Take beverages at least 30 minutes before and at the end of meals.
  • Eat small meals and try to eat foods with the most nutrition (meats and dairy products) first. Don't fill up on gelatin and sherbet.
  • Remember that breakfast may be your best meal. Include eggs, dairy products when possible or try eating some dinner items in the morning.
