Trends in eiwittransitie kunnen regionaal verschillen. In groeiende economieën verschuiven diëten wereldwijd van plantaardige naar dierlijke eiwitten. In veel economisch ontwikkelde regio's gebeurt echter het tegenovergestelde vanwege de zorg voor milieu en gezondheid. Wij onderzochten de relatie tussen vijf drijvende krachten en eiwittransitietrends zoals deze worden ervaren door jongvolwassenen in ontwikkelde regio's in China (Shanghai) en Nederland (Amsterdam, lees: de Randstad). De onderzochte drijvende krachten waren: milieubewustzijn; het beleid; cultuur; geld; en gezondheid. De gegevens zijn verkregen door 200 vragenlijsten te laten beantwoorden in beide regio's. De resultaten geven aan dat jongvolwassenen in Shanghai meer dierlijke eiwitten consumeren dan plantaardige eiwitten, maar dat er een verandering naar plantaardige eiwitten is ingezet, terwijl de trend van jongvolwassenen in Amsterdam om plantaardig eiwit te consumeren al verder ontwikkeld is. De rangschikking van de drijvende krachten in Shanghai was Geld＞ Milieubewustzijn＞ Gezondheid＞ Cultuur＞ Beleid, en in Amsterdam Gezondheid＞ Milieubewustzijn＞ Geld＞ Beleid＞ Cultuur. Eiwitkeuzes in de voeding van jongvolwassenen worden dus in Shanghai door andere drijvende krachten bepaald dan in Amsterdam

Duurzaamheidsbalans: verschillende onderzoeksrapporten laten zien dat Europese grondstoffen voor eiwit in veevoer milieuvriendelijker zijn dan soja uit Zuid-Amerika. Het is daarom vanuit milieu-oogpunt wenselijk om meer regionaal geteeld eiwitrijk veevoer te gebruiken in Nederland.Ketenaanpak: De Raad meent dat voor het oplossen van de geïdentificeerde knelpunten een ketenaanpak essentieel is. Niet slechts één partij heeft de oplossing. Momenteel ontbreekt verbinding en kennis in de keten. Voor deze verbinding is het nodig dat alle betrokken partijen met elkaar open het gesprek aangaan en elkaar betrekken bij het oplossen van ieders knelpunten.Voornaamste knelpunten 1. HANDEL: Door afspraken zoals Blair House agreement en GATT is eiwit van buiten de EU goedkoop en is een achterstand opgelopen in kennis over en ervaring met Europese eiwitteelt. 2. TEELT: De teelt van eiwitgewassen is relatief onbekend bij Nederlandse boeren, rassen zijn verouderd of onvoldoende beschikbaar en het saldo is in veel gevallen nog te laag, waarbij positieve effecten onbekend of ondergewaardeerd zijn.3. VERWERKING en 4. SCHAAL: Regionaal eiwitrijk veevoer is onvoldoende beschikbaar, vooral omdat verwerkingsmogelijkheden nog beperkt zijn en de kleinere schaal extra kosten met zich mee brengt. Dit maakt tevens investeringen onaantrekkelijk.5. MARKT: Regionaal geteeld eiwit leidt als gevolg van een hogere kostprijs tot duurder veevoer. Het halen van een meerprijs bij de consument voor producten geproduceerd met regionaal veevoer lukt (nog) niet, mede omdat er onvoldoende bewustzijn is over de problematiek. Maatschappelijke organisaties, retail en de overheid spelen hierin een rol.

More and more people worldwide live in urban areas, and these areas face many problems, of which a sustainable food provision is one. In this paper we aim to show that a transition towards more sustainable, regionally organized food systems strongly contributes to green, livable cities. The article describes a case study in the Dutch region of Arnhem–Nijmegen. Partners of a network on sustainable food in this region were interviewed on how they expect the food system to develop, and in design studies possible futures are explored. Both the interviews and the designs give support to the idea that indeed sustainable food systems can be developed to contribute to green livable cities. They show that the quality and meaning of existing green areas can be raised; new areas can be added to a public green system, and connections with green surroundings are enforced. They also show that inhabitants or consumers can be stimulated to become so called food citizens, highlighting that the relation of food systems and livable cities is a very close one.

Even in a less eventful year, it’s no easy feat: working to make our food supply healthy and sustainable. But 2020 brought a spate of new challenges. It was the year of Brexit, Black Lives Matter, and the COVID-19 pandemic. A year of hope and loss and solidarity, of masks and worries and Zoom calls. Of infection sweeping through the meatpacking industry and sometimes, of empty supermarket shelves. It was also the year that brought us the glimmering realisation that everything could be different. When so much has changed – how we work, who we spend time with, how far we venture from home – what all might be possible for food and for farming? In Flevo Campus’s latest collection of essays, thirteen journalists, scholars, and thought leaders from the US, the Netherlands, and the UK share insight into the question: How can we build resilience into our food supply – and grow more resilient ourselves? Every year, Flevo Campus publishes the best work on feeding the cities of today and tomorrow. This year’s edition includes essays by Stephen Satterfield, Charles C. Mann, Herman Lelieveldt, Hester Dibbits, Kelly Streekstra, Sigrid Wertheim-Heck, Anke Brons, Joris Lohman, Sebastiaan Aalst, Marian Stuiver, Frank Verhoeven, Emily Whyman, and Lenno Munnikes.

Due to the environmental and nutritional benefits of insects, their consumption would be one of the solutions to feed the growing human population. Despite the increasing interest in the use of insects as food and feed, consumer acceptance is the major obstacle to successful implementation in Western countries and we studied the factors that influence consumer acceptance in a group of university students from Germany and the Netherlands. In this exploratory research, a survey was conducted (n = 222). Socio‐demographic and psychological factors were established from a theoretical review. In addition, we elaborated on questions regarding information on the health and environmental benefits of consuming insects. Initially, the data obtained are presented through descriptive statistics. The influence of the socio‐demographic and psychological factors, and the information on the willingness to accept insects as animal feed and human food was analyzed using correlations and multiple linear regressions. Results showed more willingness to accept insects as animal feed than in human food. The acceptance among German and Dutch students seems to be driven by issues similar to those in other European countries, such as visual aspects and knowledge about the benefits. The effect of the information on willingness constitutes an important finding of this study, especially for the use of insects in animal feed, since most of the previous studies have focused on the use of insects as human food. Our data support the need to inform and educate consumers about the environmental and health benefits of entomophagy. We conclude that effective efforts to implement entomophagy could increase the level of familiarity with the insect food and inform (or educate) consumers about its benefits. Insights from this study are useful to address studies focusing on specific segments of possible early adopters and consequently addressing communication strategies in this market segmentation.

Understanding taste is key for optimizing the palatability of seaweeds and other non-animal-based foods rich in protein. The lingual papillae in the mouth hold taste buds with taste receptors for the five gustatory taste qualities. Each taste bud contains three distinct cell types, of which Type II cells carry various G protein-coupled receptors that can detect sweet, bitter, or umami tastants, while type III cells detect sour, and likely salty stimuli. Upon ligand binding, receptor-linked intracellular heterotrimeric G proteins initiate a cascade of downstream events which activate the afferent nerve fibers for taste perception in the brain. The taste of amino acids depends on the hydrophobicity, size, charge, isoelectric point, chirality of the alpha carbon, and the functional groups on their side chains. The principal umami ingredient monosodium l-glutamate, broadly known as MSG, loses umami taste upon acetylation, esterification, or methylation, but is able to form flat configurations that bind well to the umami taste receptor. Ribonucleotides such as guanosine monophosphate and inosine monophosphate strongly enhance umami taste when l-glutamate is present. Ribonucleotides bind to the outer section of the venus flytrap domain of the receptor dimer and stabilize the closed conformation. Concentrations of glutamate, aspartate, arginate, and other compounds in food products may enhance saltiness and overall flavor. Umami ingredients may help to reduce the consumption of salts and fats in the general population and increase food consumption in the elderly.
