Exploring the use of alternative diets in people living with cancer.

There is significant use of alternative diets by people living with cancer, with data suggesting this has continued to increase since the 1980s. Commonly used alternative diets include the ketogenic diet, Gerson therapy, alkaline diets and fasting diets. This article explains the latest trends in relation to alternative diets, discusses the reasons why people may want to use these and examines their hypothesised mechanisms of action. The author outlines and critically reviews the evidence underpinning the use of such diets in those living with cancer, and suggests that this remains weak. The article also explores the challenges that nurses may experience when a person living with cancer wishes to adopt an alternative diet, and provides practical advice and recommendations on nutrition.

Providing optimal nursing care for patients undergoing enteral feeding.

Enteral feeding is defined as the intake of food directly into the gastrointestinal (GI) tract. Enteral feeding tubes can also be used to administer medicines. Patients who may require enteral feeding include those who are unconscious, or those with neurological swallowing disorders, upper GI obstruction, GI dysfunction or malabsorption. There are several routes that can be used for enteral feeding including gastrostomy, post-pyloric, nasogastric, continuous pump and bolus feeding. When undertaking enteral feeding, nurses and other healthcare professionals should be aware of the potential complications such as tube blockage and infection. This article examines the various enteral feeding routes, discusses the administration of medicines, and details the common complications associated with enteral feeding.
