[The challenge of nutrition in palliative care: Eating and drinking - beneficial even at the end of life?].

Food and nutrition play a major role in our lives. They include physical, psychological as well as cultural and social aspects. Illnesses increase the risk of altered food intake/absorption - of malnutrition. This applies in particular to palliative situations. The causes of malnutrition can be diverse. Malnutrition often leads to reduced performance and can therefore have a major impact on the quality of life and independency of patients. The aim of nutritional therapy interventions is therefore to maintain or improve the quality of life of patients with a life-threatening illness. The initially defined goals can change as the disease progresses. At the beginning of a life-threatening illness, adequate nutritional interventions are usually very effective. However, the benefits of nutritional therapy often change as the disease progresses and they often lose importance. For this reason, decision-making is an important process: Depending on the phase of illness, the prognosis and the patient's preferences, the nutritional therapy interventions needs to be reconsidered in regard of indication, individual benefit and the desired treatment goal on a regular base. As every medical intervention, nutritional therapy must regularly be adapted to the treatment goal if necessary.
