INTRODUCTION
Nutrition plays a vital role throughout our lives. It lays important foundations in the womb and gives us vital building blocks during periods of rapid growth from infancy and through the teenage years. In adulthood, proper nutrition helps to maintain a strong immune system, provides us with energy and other vital nutrients for the day-to-day functions of our body, and can help to prevent and manage many diseases. Good nutrition has also been proved to help prevent most major cancers. And even during illness, nutrition continues to play an essential role in treatment of the disease and the eventual outcome. Scientific studies have demonstrated time and again that a good nutritional state during illness, including cancer, can help keep energy levels up, prevent weight and muscle loss, and improve immune functions. People who have a poor nutritional status have a higher risk of developing infections. Some studies have even shown that cancer treatments such as chemotherapy are not well tolerated and are in fact often stopped early in undernourished patients.
Although good nutrition is essential during illness and cancer therapy, there are several reasons why it is difficult to follow a healthy diet. Most people feel overwhelmed and confused when trying to find out what they should be eating suddenly every well-meaning family member, friend or colleague becomes an expert on nutrition. And trying to separate sound information from myths on the internet is nearly impossible. Then there are the supplements, herbs and other miracle remedies which will help and which will do more harm.
The aim of this book is to provide sound, evidence-based guidelines on what to eat during this stressful time. We will also give practical advice on what to eat to help manage some of the side effects often associated with cancer therapy. The information provided was accurate at the time of publication.
In addition, we look in detail at some of the most common cancers and what to eat when diagnosed with one of them, depending on what treatment is being used.
Seeing a loved one undergo cancer treatment is also an emotional, stressful time for family and friends. One of the ways of caring for and showing our support for the cancer sufferer is to provide food, but doing this can also be a challenging task, as many people are unsure what to cook. To help, this book is filled with tasty and healthful recipes that are also easy to prepare.
If you would like more information on what to eat, or if you need more support with your diet, contact your registered dietitian.
Please refer to the list at the back of the book for resources and organisations to consult for more information on other aspects of cancer and its treatment, besides nutrition, which is discussed here.
