Nutrition in Survivorship Care

In recent years, the attention on the role of diet and physical activity in the health status of cancer survivors has increased. The progress in early diagnosis and treatment of cancer has led to a continually increasing number of cancer survivors, which is associated with a corresponding growth in the need for effective posttreatment management programs. Several nutritional guidelines have been published for cancer survivors to achieve a better prognosis and quality of life. In 2018, the World Cancer Research Fund (WCRF) updated its previous extensive systematic review of the evidence linking food, nutrition, and related factors to cancer incidence. It also addressed the issue of cancer survivors and concluded that due to the lack of sufficient research evidence, they should be encouraged to follow the recommendations for primary prevention. Currently, there is still insufficient research evidence regarding the effects of diet, weight, and nutrition on the risk of cancer recurrence. The research in this area, unlike for primary prevention, is often inconclusive and the WCRF report remains the most authoritative source of evidence.
