This booklet has been written for people affected by cancer or those wishing to reduce their risk of cancer. It contains general guidance and is not meant to be prescriptive. Everyone has unique nutritional requirements that depend, amongst other things, on genetic make up, medical history, stage of treatment, current state of health, and lifestyle, as well as tastes and preferences. The guidelines can be adapted to suit your own tastes and needs. If you have special dietary needs or problems with eating, swallowing, digestion, or weight loss you should seek further advice from a nutritionally-qualified health professional who has experience of working with people affected by cancer.
