Patients with colorectal cancer may have a variety of nutrition-related symptoms, such as weight loss, anorexia, and taste changes, which affect their health. 

Therefore, good nutrition is essential to reduce symptoms and improve quality of life. A diet consisting of foods that will maintain a healthy weight and prevent the advancement of cancer may be useful for cancer patients.[1]


Certain foods and drinks may be harmful during and after colorectal cancer treatments and so should be avoided. Such food include: [2]


  • Foods and drinks which are high in simple sugars like candy and sugary desserts

  • Foods that are high in saturated fats and trans fats like lamb, butter, pork, and processed snacks

  • Caffeine

  • Greasy and fried foods

  • Carbonated drinks and soda. [2]


According to the National Cancer Institute, cancer patients should limit the consumption of foods high in saturated fat and sodium. High sodium foods include packaged and processed foods such as canned soups, crackers, pasta, frozen entrees, and condiments. Many snacks and bakery products contain sources of sodium and trans-fat and should therefore also be avoided. [1]


A juicy burger out of the grill can seduce the taste buds, but this can be bad news for the colon. Scientists know that regular red meat, such as beef, pork, and lamb; can increase the risk of colorectal cancer. This may be due to the meat itself or the formation of carcinogenic substances when cooking at high temperatures. [3


Some studies have shown that people who consume red meat frequently with eggs, cheese, and other fatty foods, as well as refined starches, were almost twice as likely to develop rectal or colon cancer as their peers who favored a plant-based diet. [4]

In addition to foods high in fat and sodium, alcohol and tobacco should also be avoided in patients with colon cancer. [1]


Processed meats are smoked, dried, salted, or preserved with added chemicals. Think of hot dogs, bacon, ham, bologna, and packaged meat. Eating this type of meat can often increase the risk of colorectal cancer, so it is also advisable not to consume processed meat. [3]
