Zusammenfassung
Patienten befolgen häufig eine oder mehrere Krebsdiäten. Diese Diäten erfordern oft unnötige Nahrungseinschränkungen und können für die Patienten – unabhängig von ihrem Krankheitszustand – zu negativen Folgen führen. Es fehlt nicht nur an wissenschaftlichen Erkenntnissen zur Untermauerung solcher Empfehlungen, sondern die Diäten können oft auch das Risiko einer Mangelernährung erhöhen. Deshalb sind patientenzentrierte Beratungen notwendig, um das Bewusstsein für die Folgen von Krebsdiäten zu schärfen und eine informierte Entscheidungsfindung zu fördern. Falls zeitliche Beschränkungen solche Gespräche verhindern, ist es dennoch wichtig, die Entscheidungsfindung der Patienten zu steuern, indem man ihnen geeignetes, wissenschaftlich fundiertes Informationsmaterial zur Verfügung stellt und/oder auf eine qualifizierte Ernährungstherapie verweist.
Abstract
Patients often follow one or more cancer diets. These diets often require unnecessary food restrictions and can lead to negative consequences for the patients regardless of their disease state. There is not only a lack of scientific evidence backing such recommendations, but often the diets can increase the risk for malnutrition. Patient-centered consultations are therefore necessary to increase awareness about the consequences of cancer diets and encourage informed decision making. If time restrictions prevent such consultations, it is still important to steer patient’s decision making by providing them with appropriate, scientifically sound informational material and/or encourage them to seek medical nutrition care from a qualified professional.
