Diet - cancer treatment

Table of Contents

  • Add diced meat or cheese to sauces, vegetables, soups, and casseroles.
  • Add extra eggs or egg whites to foods. Never use raw eggs. They may be contaminated with salmonella, which is dangerous for everyone but especially those who are immune-suppressed. Raw eggs also contain a vitamin binder.
  • Add powdered milk to foods and beverages.
  • Consider using commercially available nutritional supplements. Make your own high-calorie shake by adding an instant breakfast drink mix to milk, fruit, cookies, peanut butter, or other favorite mixers.
  • Drink high-calorie beverages such as juices, milk, or sweetened drinks.
  • Eat smaller, but more frequent meals.
  • If you are unable to digest fat, talk to your health care provider about alternative fat sources. Supplements containing medium-chain triglycerides are often recommended for this purpose.
  • Increase fats in the diet to increase energy consumption, if you are tolerating fats. Add margarine or butter to breads and vegetables. Add gravies and sauces to foods in large amounts.
  • Increase protein and calories in the diet.
  • Snack throughout the day on calorie-dense foods such as nuts, hard candy, and dried fruits.

LACTOSE INTOLERANCE

Some cancer patients become unable to digest dairy products, which is called lactose intolerance. Symptoms include bloating, gas, and diarrhea immediately after eating lactose-containing foods.

People with lactose intolerance have trouble digesting the sugar in milk. Lactose intolerance is due to an inability to produce lactase, the enzyme that digests milk. The wall of the gastrointestinal tract produces this enzyme. You can take lactase to help you digest lactose products.

You can also buy lactose-free milk at most grocery stores. Cultured dairy products such as yogurt, cheeses, and buttermilk will contain less lactose, because the active cultures help to digest it.

You may be able to tolerate small amounts of lactose occasionally. Or, you may have to remove lactose entirely from your diet until you have fully recovered from your cancer therapy.

DUMPING SYNDROME

Surgery on the stomach may cause dumping syndrome. If you have dumping syndrome, food is "dumped" into the small intestine 10 or 15 minutes after being swallowed. Ordinarily, food is partially digested in the stomach, then released gradually into the digestive tract.

The presence of undigested food in the intestine leads to:

  • Abdominal fullness
  • Crampy abdominal pain
  • Feeling warm, dizzy, and faint
  • Nausea
  • Rapid pulse and cold sweats immediately after eating

Recommendations for dumping syndrome are:

  • Drink fluids 30 minutes before a meal or 30 - 60 minutes after a meal.
  • Eat smaller, more frequent meals.
  • Lie down immediately after eating.
  • Restrict refined carbohydrates and increase protein and fat in the diet.

LOSS OF APPETITE

If you are experiencing loss of appetite, adjust your diet to include any foods that appeal to you. Consider asking your doctor about appetite-stimulating drugs.
