An exploration of the idea that tangible change could be made in the world when norms are unsettled rather than reinforced or left untouched. Bloom focuses on creating a space for the individual to re-define the outdated, toxic norms surrounding masculinity to explore ‘what men can be’. This is tied into questioning ‘what food can be’ — now and in the future — in relation to the norm of consuming animal food products in western societies. In collaboration with people who have actively reduced their meat consumption or identify as plant based or vegan, I have aspired to use my practice as a visual communicator to illustrate connections and reveal hidden narratives of these individuals who are already challenging these norms as change agents within society. The outcome is the Bloom Box — an interactive box containing their stories visualised with ‘out of the norm’ plant foods.

The demand and consumption of food products created by the livestock- and fishing industries, have a major environmental impact, affecting climate change, biodiversity, and ecosystems. Yet, there seems to be a lack of public awareness of the direct impact one’s choice of food has on the environment, which suggests that more effective efforts are needed in order to introduce the concept to consumers. By the influence of a post-humanist perspective, this thesis investigates how the environmental impact of consuming animal-based food is communicated by Swedish environmental non-governmental organizations, and how the organizations are actively working to change consumers’ dietary habits by selecting more sustainable options. The research has focused on the external communication channels of the organizations, where verbiage and imagery have been analyzed in context, by using an analytical perspective of a constructionist view of communication, of where I acknowledge that communication has changed in our digital society. The findings indicated that the organizations are showing clear efforts and willingness of communicating the environmental impact of consuming animal-based food, although these efforts remain quite limited. The promotion of a plant-based diet as a way to help mitigate climate change was also communicated to a fair extent, but the organizations seemed to be privileging the preferences of consumers for animal-based food products over the actual need for them. Given that scientific evidence has shown that human consumption of animal-based food products has a major environmental impact, the overall produced knowledge by the organizations’ communication of consuming such products is still lacking. This suggests that more effective communication efforts are still needed, given the severity of the issue, which requires a drastic social change in eating habits as currently practiced in developed nations, in order to effectively mitigate climate change.

As the population of the world increases and cities grow in size, we are faced with remarkable societal problems regarding sustainable food security for the generations to come. In this paper, I present and discuss HAVE (Hydroponic Agricultural Vertical Environment), a research-through-design project that explores the design of an interactive open-source vertical kitchen garden. HAVE is designed as a shareable platform, that aims to lower the barriers of entry of getting started with home gardening, to provide an option for people to play an active role in working towards a more sustainable, resilient society. By simplifying the design of a computer-assisted garden, I present an engaging interactive system that is cheap and easy to build and maintain. With HAVE as a case study, this project also aims to expand upon how plant-based interfaces can be implemented in future design work, and builds upon the topics of calm technology and material computing. As such, this paper discusses the opportunities and challenges of designing plant-based interfaces, also in relation to how people care for and interact with plants. It is my hope, that HAVE may act as a conversation piece that addresses societal challenges regarding future agriculture practices, while contributing to the academic discussion and debate on the topics of plant-based interfaces, design for social innovation, and tangible computing, and the field of interaction design in general.

The hepatitis B virus (HBV) is a common virus, with two billion people infected worldwide. It causes approximately 600,000 deaths each year, despite the availability of an effective vaccine since 1982. Maize as a platform for oral vaccination can supply a heat stable vaccine, which does not require syringes or trained personnel to administer. The Hepatitis B Surface antigen was transformed into maize and this seed was used to evaluate expression levels through the breeding process. The transgene was transferred into two elite maize inbreds by backcrossing. Highest expressing ears were selected each generation until approximately 99% commercial parent was obtained with a single gene coding for the vaccine present. Selected individuals were crossed to create hybrid plants. This work was done to create high expressing high yielding lines that could be used as a plant-based oral vaccine for Hepatitis B.

In the recent years, the consumer choices have been focused on health-promoting plant-based food and their preferences are oriented towards regional foodstuff from local productions. Therefore, an important factor for vegetables grown Trentino-Alto Adige (Italy) is to point out the added value of alpine farming to evaluate the nutritional values of farming products. Omics technologies (e.g. genomics, transcriptomics, proteomics and metabolomics) are aimed at investigating the assessment of different pools of molecules and how they are translated into the structure, function, and dynamics of a biological system or systems in order to provide a comprehensive characterization of a specific organism. Research use the omics techniques to exhaustively understand the functionality of food components. Several sophisticated chromatographic methods, spectroscopic techniques and chemometric tools are applied to give an insight into a comprehensive overview of the intrinsic quality, typicality and regionality of specific plant-based foods in the present PhD thesis: apples and potatoes. The quality of these foods is evaluated by quantifying the secondary metabolites to investigate their nutraceutical values. The aim of this PhD project is to use several analytical techniques (LC-MS, UV-VIS) that are capable of comprehensively characterizing the food metabolome with particular emphasis on those components with high nutritional values. The data analysis and data handling of omics data requires advanced bioinformatic, statistical, and chemometric tools. Potatoes and apples are chosen as target matrices for these studies for their relevance in the local economy and for the peculiar chemical composition of particular interest for their health-promoting proprieties. The information is acquired using several sophisticated chromatographic and spectroscopic techniques, such as ultra-high performance liquid chromatography coupled with triple quadrupole mass spectrometry (UHPLC– MS/MS) and UV/VIS. It is integrated to chemometric approaches (principal component analysis (PCA), partial least square regression (PLS), and data fusion) to achieve a comprehensive targeted chemical characterization. The sampling procedures gathers, in the case of the potatoes study, reference cultivars that may be found in the common retailers of Trentino/Alto-Adige and different production areas, the apples of 22 cultivars were harvest from the fields of the Laimburg Research Centre (Vadena, Italy) to guaranty comparability of the obtained data. Our results may be used as solid foundation for a reliable evaluation of apples and potatoes healthy "potential" value based on cutting-edge techniques, which are capable of providing comprehensive data regarding the alpine food quality parameters with high efficiency and reliability

Background: Polyphenols are secondary metabolites produced by plants to defend themselves from environmental stressors. We explored the effect of Wolffia globosa ‘Mankai’, a novel cultivated strain of a polyphenol-rich aquatic plant, on the metabolomic-gut clinical axis in vitro, in-vivo and in a clinical trial. Methods: We used mass-spectrometry-based metabolomics methods from three laboratories to detect Mankai phenolic metabolites and examined predicted functional pathways in a Mankai artificial-gut bioreactor. Plasma and urine polyphenols were assessed among the 294 DIRECT-PLUS 18-month trial participants, comparing the effect of a polyphenol-rich green-Mediterranean diet (+1240 mg/polyphenols/day, provided by Mankai, green tea and walnuts) to a walnuts-enriched (+440 mg/polyphenols/day) Mediterranean diet and a healthy controlled diet. Results: Approximately 200 different phenolic compounds were specifically detected in the Mankai plant. The Mankai-supplemented bioreactor artificial gut displayed a significantly higher relative-abundance of 16S-rRNA bacterial gene sequences encoding for enzymes involved in phenolic compound degradation. In humans, several Mankai-related plasma and urine polyphenols were differentially elevated in the green Mediterranean group compared with the other groups (p < 0.05) after six and 18 months of intervention (e.g., urine hydroxy-phenyl-acetic-acid and urolithin-A; plasma Naringenin and 2,5-diOH-benzoic-acid). Specific polyphenols, such as urolithin-A and 4-ethylphenol, were directly involved with clinical weight-related changes. Conclusions: The Mankai new plant is rich in various unique potent polyphenols, potentially affecting the metabolomic-gut-clinical axis.

Restricting animal-based products from diet may exert beneficial effects on weight status; however, less is known about such a diet and emotional health. Moreover, personality traits, for example high neuroticism, may contribute to restrictive eating habits and potentially confound diet-health associations. We aim to systematically assess if restrictive dietary intake of animal-based products relates to lower weight and higher depressive symptoms, and if differences in personality traits play a significant role. Cross-sectional data from the baseline LIFE-Adult study were collected from 2011–2014 in Leipzig, Germany (n = 8943). Main outcomes of interest were dietary frequency of animal-derived products in the last year measured using a Food Frequency Questionnaire (FFQ), body-mass-index (BMI) (kg/m2), and the Center of Epidemiological Studies Depression Scale (CES-D). Personality traits were assessed in a subsample of n = 7906 using the Five Factor Inventory (NEO-FFI). Higher restriction of animal-based product intake was associated with a lower BMI, but not with depression scores. Personality, i.e., lower extraversion, was related to higher frequency of animal product intake. Moreover, personality traits were significantly associated with depressive symptoms, i.e., higher neuroticism, lower extraversion, lower agreeableness, lower conscientiousness, and with higher BMI. These findings encourage future longitudinal studies to test the efficacy of restricting animal-based products as a preventive and therapeutic strategy for overweight and obesity.

Background: Rare plants that contain corrinoid compounds mostly comprise cobalamin analogues, which may compete with cobalamin (vitamin B12 (B12)) metabolism. We examined the presence of B12 in a cultivated strain of an aquatic plant: Wolffia globosa (Mankai), and predicted functional pathways using gut-bioreactor, and the effects of long-term Mankai consumption as a partial meat substitute, on serum B12 concentrations. Methods: We used microbiological assay, liquid-chromatography/electrospray-ionization-tandem-mass-spectrometry (LC-MS/MS), and anoxic bioreactors for the B12 experiments. We explored the effect of a green Mediterranean/low-meat diet, containing 100 g of frozen Mankai shake/day, on serum B12 levels during the 18-month DIRECT-PLUS (ID:NCT03020186) weight-loss trial, compared with control and Mediterranean diet groups. Results: The B12 content of Mankai was consistent at different seasons (p = 0.76). Several cobalamin congeners (Hydroxocobalamin(OH-B12); 5-deoxyadenosylcobalamin(Ado-B12); methylcobalamin(Me-B12); cyanocobalamin(CN-B12)) were identified in Mankai extracts, whereas no pseudo B12 was detected. A higher abundance of 16S-rRNA gene amplicon sequences associated with a genome containing a KEGG ortholog involved in microbial B12 metabolism were observed, compared with control bioreactors that lacked Mankai. Following the DIRECT-PLUS intervention (n = 294 participants; retention-rate = 89%; baseline B12 = 420.5 ± 187.8 pg/mL), serum B12 increased by 5.2% in control, 9.9% in Mediterranean, and 15.4% in Mankai-containing green Mediterranean/low-meat diets (p = 0.025 between extreme groups). Conclusions: Mankai plant contains bioactive B12 compounds and could serve as a B12 plant-based food source.

One of several ways mankind can collectively do in order to fight the climate crisis and contribute to the mitigation of greenhouse gas emissions is by switching to a more plant-based diet. Serious games and various gamification tools have been used to raise awareness of current problems and motivate individuals to shift to a more “pro environmental” behaviour. This study focuses on the perceived potential of a gamified application to make dietary changes, as well as on the perceived usefulness of gamification as a tool to achieving a certain goal. In order to seek answers to the aforementioned questions a prototype was developed and an online survey was conducted. The results show that there is a potential of this specific product to help people transitioning towards a more plant-based diet. However, more studies ought to be conducted in order to see the true benefits of it.
