What you eat and drink are important not only for prevention, but also during your fight against colorectal cancer and into your survivorship.

As you move from diagnosis to treatment and surgery, your dietary needs will change. After surgery, you will be on a “low residue” diet. This is a diet low in fiber. It will minimize the amount of work for your colon and rectum. Think “white bread and white rice, not whole grain bread and brown rice,” and avoid foods like raw vegetables, nuts and seeds, whole grain products, beans, fried meats.

For a more detailed list of what to eat and what not to eat, visit the American Cancer Society.

You may not feel like eating or drinking during treatment. Foods may taste differently, and side effects like mouth sores or cold sensitivity might make it hard to eat. It’s important to make sure you get proper nutrients and combat unwanted weight loss.
