Context: There is an ongoing debate about whether and how fructose is involved in the pathogenesis of nonalcoholic fatty liver disease (NAFLD). A recent experimental study showed an increased intrahepatic triglyceride (IHTG) content in mice deficient for aldolase B (aldo B−/−), the enzyme that converts fructose-1-phosphate to triose phosphates. Objective: To translate these experimental findings to the human situation. Design: Case-control study. Setting: Outpatient clinic for inborn errors of metabolism. Patients or Other Participants: Patients with hereditary fructose intolerance, a rare inborn error of metabolism caused by a defect in aldolase B (n = 15), and healthy persons matched for age, sex, and body mass index (BMI) (n =15). Main Outcome Measure: IHTG content, assessed by proton magnetic resonance spectroscopy. Results: IHTG content was higher in aldo B−/− patients than controls (2.5% vs 0.6%; P = 0.001) on a background of lean body mass (median BMI, 20.4 and 21.8 kg/m2, respectively). Glucose excursions during an oral glucose load were higher in aldo B−/− patients (P = 0.043). Hypoglycosylated transferrin, a surrogate marker for hepatic fructose-1-phosphate concentrations, was more abundant in aldo B−/− patients than in controls (P < 0.001). Finally, plasma β-hydroxybutyrate, a biomarker of hepatic β-oxidation, was lower in aldo B−/− patients than controls (P = 0.009). Conclusions: This study extends previous experimental findings by demonstrating that aldolase B deficiency also results in IHTG accumulation in humans. It suggests that the accumulation of fructose-1-phosphate and impairment of β-oxidation are involved in the pathogenesis.

Wageningen : Wageningen Food & Biobased Research (Report / Wageningen Food &amp; Biobased Research 1966) - ISBN 9789463950404 - 23
This report provides the technical results of the second dry run transporting mangoes and avocados from Haiti to the US. For both fruits, temperature has been registered from the moment of harvest till arrival at destinations. Also logistical data like planning preparing the test, time needed for each step, and quality of fruits has been analysed, following the procedures as presented in the Standard Operational Procedures for both fruits. The process was organised together with the two new partners Haiti Mango Consortium and Agriledger, both contracted by MCI for the next phase of exporting fruits to the US. After an introduction chapter, technical observations and remarks are provided for both mango and avocado in the next two chapters, with a concluding last chapter afterwards that provides overall analysis, lessons learned and recommendations. Based on the lessons learned the Standard Operation Procedures (SOPs) will be updated. A major change will be that Collection Points will be introduced as transport from tree to truck cannot be controlled by project partners. SOPs will be updated over the coming months June-July 2019.

The first week of PNIPA-WUR IV, organized between the 11th and the 15th of February, 2019, WUR staff helped the PNIPA team to redesign the Rapid Appraisal of Agricultural Innovation System (RAAIS) methodology and apply it to activate innovation networks. In addition, assistance was provided for preparing the October 2019 symposium, introducing the MSP guide and selecting tools, starting the PNIPA partnership component for professional education in the P&A sector and general advise and coaching for the program.The second week of PNIPA-WUR IV, organized between the 18th and the 22nd of February, 2019, consisted of two interlocked components. During the first part of the week a core team of PNIPA prepared to run an innovation network workshop with key stakeholders and actors of the Paiche valuechain in the Department of San Martin. A methodological tool, consisting of RAAIS and MSP elements, was tailored to PNIPA needs. PNIPA experts were trained in the methodology and facilitation skillsrequired to run the workshop. During the second part of the week the PNIPA team ran the workshopwith more than 20 stakeholders, representing different segments of the Paiche sector in San Martin. As a result of the workshop, key actors in the Paiche sector committed themselves to be part of aninnovation network with clearly defined work plans and activities. The continuous reflexive evaluationof the PNIPA team has generated a tailored approach to run an innovation network workshop that supports actors in a particular value chain or sector to plan strategic activities geared to tackle the critical constraints that are limiting the development of the sector a particular area. The methodologysupports the emergence of networks of actors working together to innovate, strengthen and develop aparticular sector or priority domain.

Alkali activated binder - Ionic behaviour - Lignocellulose - Moisture content - NMR - Reaction kinetics

This study investigates the suitability of alkali activated binders to replace Portland cement for lignocellulosic mineral-binder composite, aiming to lower the CO2 footprint. The effects of wood composition on the reaction kinetics of the binders and the formation of the reaction products are studied using isothermal calorimetry and ion chromatography. The ionic behaviour analysis of Ca2+ and Na+ ions in the binders shows that in presence of wood, a neutralisation of OH ions and reduction of Ca2+ and Na+ ions during the first 24 h of curing take place, which alters the formation of C-A-S-H and N-A-S-H gels and influences the final composite performance. Moreover, the position of water absorbed by wood with different moisture levels is investigated by using T2 relaxometry Time Domain (TD) NMR to understand the required water amount for the binder reaction as well as the liquid uptake of the wood and occurring ion migration. The results show that a hybrid binder consisting of 70% alkali activated material and 30% cement applied without NaOH pre-treatment results in a composite with excellent mechanical performances and reduced environmental impacts of 61.5% compared to a pure cement system.

Food systems in low and middle income countries are changing rapidly in response to economic and market developments, environmental impacts, and dietary changes. Within this context, informed policy and sustainable development processes are needed to shape climate-smart and resilient food systems for food and nutrition security at farming household level. This research project aimed to a) explore the complexity of the contextual dynamics in which smallholder farming households operate; and b) contribute to a better conceptual understanding of commercial food production strategies in relation to consumption choices. A literature review was conducted, exploring both scientific and grey literature, in parallel to consultation rounds with a multidisciplinary team of agronomists, economists, nutritionists and international development specialists to explore existing insights, align available expertise, and find common ground on how to create a useful framework that would fit the specific interests and expertise of each of the actors involved. Key elements for our framework were preliminary drawn from existing frameworks. A number of - non-exclusive - pathways were identified. These include subsistence-oriented production for the household’s own consumption (source of food), whereby women – as producers as well as care takers - are seen as the crucial agents for household food security and health outcomes; production for sale in markets (source of income); and agricultural policies (national and global), affecting a range of supply and demand factors that establish the price of marketed food and non-food crops (food price policies). The important characteristics for the framework for viable commercial agriculture and consumption of nutritious foods evolve around different aggregation levels: the individual (gender and power dynamics), the household (household food production, income generation, food purchase choices, care practices, access to health care), the community (employment opportunity, collaboration, microfinance, care and social (infra)structure), and the regional/nation (price and trade policy) level.

Consumer Behaviour - Food Waste Prevention - Impact Assessment - ICT Tools - Apps
It is part of the EU research project REFRESH, which aims to contribute to the goal of reducing food waste across Europe. A literature search in 2018 resulted in only twelve papers that focus on the topic of apps in relation to consumers’ sustainability behaviour. The scarce evidence indicates that apps can be effective in raising consumer awareness indicated, but not much is known about the effects of using apps on food waste behaviour of consumers. Therefore, two subtasks were executed within task 1.5: an inventory of available ICT tools and a consumer focus group study. Via an online search in 2016 & 2017, suggestions from REFRESH project partners and tools mentioned in publications, an inventory was made of existing ICT based tools for food management and waste reduction by consumers. The functionalities of these apps were analysed for the different phases of the household food logistics. The aim of this inventory was to give an overview of existing apps and examples of the diversity of functionality of the apps. Based on the criteria of a high number of installations or novelty, three apps from this inventory were selected for use in the consumer focus group study. All apps had different features. The aim of the focus group discussion was to gain insight in how consumers experienced the use of the apps and to what extent using the apps led to a change in self-reported behaviour.

Food systems undergo rapid changes in response to economic and market forces, andenvironmental and dietary changes. This study aimed to disentangle adaptation strategies infarm households balancing interests in the commercial aspects of farming and the consumptionof nutritious foods. The area of interest was Central Myanmar, Pakokku region. A literature-basedframework was used to identify entry points for adaptation strategies at the farm household level.A purposive sampling strategy was used to select smallholders (<5 acres), engaged in market-orientedagriculture (10 years). In 14 households, in-depth interviews were conducted, using a life courseperspective depicting the household history in relation to agricultural developments and householdfood and nutrition security. The narratives of smallholders confirmed that household food andnutrition security was grounded in mixed livelihood strategies, including migration. Diet qualitydepended largely on income. Supportive strategies were a frugal lifestyle, responsible use of resources,participation in community activities, and different forms of social innovation. The study shows howthe understanding of local diets provides insights in entry points for nutrition-sensitive agriculture,and suggests a need for alternative adaptation strategies, replacing those promoting specializationand intensification, for more holistic solutions that reinforce the flexibility and resilience of farmers.
Capturing Social Innovations in Agricultural Transformation from the Field: Outcomes of a Write-Shop
Peters, Bram ; Herens, M.C. ; Brouwers, J.H.A.M. - \ 2018
Sustainability 10 (2018)12. - ISSN 2071-1050
The aim of this project was to explore the theme of social innovation for nutrition-sensitive and sustainable agriculture, resulting in examples of improved production and consumption of nutritious food. Social innovation refers to the generation and implementation of new ideas about how people organize interpersonal activities, or social interactions, to meet one or more common goals and in the process change basic routines, resources, and decision-making processes. In the country context of Myanmar, this research aimed to capture a variety of social innovation cases related to processes of agricultural transformation. Through the method of a collaborative case study write-shop, Myanmar-specific social innovations were identified, illustrating various forms of social innovation across the cases with citizen engagement processes. The write-shop method, in combination with the embedded expertise of development practitioners, proved to be a promising approach to identify niche innovations, distil insights, reframe actions, and promote critical thinking among different actors.
