Maresa Anna Temmen untersucht auf Grundlage der Theorie der kognitiven Hierarchie die Konsumbereitschaft fur In-vitro-Fleisch und pflanzenbasierte Fleischersatzprodukte in Deutschland. Hierzu werden unter anderem ernahrungspsychologische Einflussfaktoren genutzt, die sich auf moralische und ideologische Einstellungen zum Fleischkonsum beziehen. Die Ergebnisse der quantitativen Online-Fragebogenstudie zeigen, dass die Konsumbereitschaft fur In-vitro-Fleisch und pflanzenbasierte Fleischersatzprodukte in der deutschen Bevolkerung relativ hoch ist und stutzen die Theorie der kognitiven Hierarchie: Entsprechend konnen eine universalistisch gepragte Wertestruktur, eine geringe soziale Dominanzorientierung, eine geringe Auspragung von Speziesismus und karnistischer Dominanz sowie eine geringe Unterstutzung von Rechtfertigungsstrategien fur den Konsum von Fleisch Grunde fur eine hohe Konsumbereitschaft von In-vitro-Fleisch und pflanzenbasierten Fleischalternativen sein. Die Studie zeigt, dass tiefliegende Personlichkeitsvariablen wie Werte und Wertorientierungen einen Einfluss auf spezifischere Einstellungen nehmen, die wiederum einen Einfluss auf die Konsumbereitschaft von Fleischalternativen haben.

Lebensmittel sind Mittel zum Leben. Die Art und Weise ihrer Erzeugung betrifft uns alle. Weitgehend unbemerkt von der offentlichen Wahrnehmung hat sich in den vergangenen Jahrzehnten ein System der Agrar- und Ernahrungsindustrie entwickelt, das uns mit einer Fulle von Nahrungsmitteln mit zu niedrigen Preisen versorgt.Die unerwunschten Nebenwirkungen und externen Kosten dieses Systems wurden jedoch lange Zeit ausgeblendet. Enorme Umwelt- und Klimabelastungen, Verlust der Biodiversitat, tierschutzrelevante Missstande und ein anhaltendes Hofsterben beschreiben nur unzulanglich das wahre Ausma an Schadwirkungen. Im Interesse des Gemeinwohls konnen diese nicht langer hingenommen werden. Allerdings stehen die Komplexitat der Sachverhalte und vielfaltige Partikularinteressen einfachen Losungen entgegen.Dieses Fachbuch liefert eine umfassende systemische Analyse aus sehr unterschiedlichen Perspektiven und erlautert, wie es zu dieser Entwicklung hat kommen konnen. Es wird aufgezeigt, welche grundlegenden Veranderungen in allen Bereichen erforderlich sind, um uber eine evidenzbasierte Qualitatserzeugung einen Ausweg aus dem zerstorerischen Streben nach Kostenminimierung zu finden. Fachkrafte der Agrar- und Ernahrungsindustrie und der involvierten wissenschaftlichen Fachdisziplinen, einschlielich der Veterinarmedizin, sowie Entscheidungstrager in politischen Institutionen, Berufsverbanden und NGOs konnen dieses Wissen fur eine zukunftsfahige Neugestaltung des Lebensmittelsektors nutzen.
