  • Oat protein nanofibril–iron hybrids offer a stable, high-absorption iron delivery platform for iron fortification
    Item type: Journal Article
    Zhou, Jiangtao; Gowachirapant, Sueppong; Zeder, Christophe; et al. (2025)
    Nature Food
    Iron deficiency and anaemia affect two billion people globally. Iron fortification can help to treat anaemia, but most current fortificants are limited by low absorption and/or poor sensory properties. Here we introduce oat protein nanofibrils (OatNF) carrying ultrasmall iron nanoparticles that are engineered to carry iron in ferrous or ferric form. In a prospective cross-over stable-isotope absorption trial in young iron-deficient women (n = 52), OatNF reduced with sodium ascorbate carried mainly ferrous iron and showed high fractional absorption with water and with polyphenol-rich food, showing 1.76- and 1.65-fold higher absorption, respectively, compared with ferrous sulfate. When sodium hydroxide was used as the reducing agent, OatNF carried mainly ferric iron, which was also well absorbed and featured good sensory properties in reactive food matrices. OatNF hybrids offer a plant-based strategy for delivering highly bioavailable iron for food fortification.
  • Policy framing, design and feedback can increase public support for costly food waste regulation
    Item type: Journal Article
    Fesenfeld, Lukas; Rudolph, Lukas; Bernauer, Thomas (2022)
    Nature Food
    Stricter regulation of food waste reduction is widely presumed to increase food prices, which could render its implementation politically unfeasible. Here we empirically tested whether specific policy framing, design and feedback could help ensure public support despite potential food price increases. We used survey experiments with 3,329 citizens from a high-income country, Switzerland. A combined framing and conjoint experiment shows that messages emphasizing national or international social norms in favour of reducing food waste (policy framing) can increase public support for more ambitious reduction targets. Also, most citizens support food waste regulation even if this leads to substantial increases in food prices, but only if such policies set stringent reduction targets and are transparently monitored (policy design). Finally, a vignette experiment reveals that voluntary industry initiatives do not crowd out individuals’ support for stricter governmental regulation, but potentially crowd in support if industry initiatives are unambitious (policy feedback).
  • Multi-model assessment identifies livestock grazing as a major contributor to variation in European Union land and water footprints
    Item type: Journal Article
    Vanham, Davy; Bruckner, Martin; Schwarzmueller, Florian; et al. (2023)
    Nature Food
    Food systems are the largest users of land and water resources worldwide. Using a multi-model approach to track food through the global trade network, we calculated the land footprint (LF) and water footprint (WF) of food consumption in the European Union (EU). We estimated the EU LF as 140–222 Mha yr−1 and WF as 569–918 km3 yr−1. These amounts are 5–7% of the global LF and 6–10% of the global WF of agriculture, with the EU representing 6% of the global population. We also calculated the global LF of livestock grazing, accounting only for grass eaten, to be 1,411–1,657 Mha yr−1, and the global LF of agriculture to be 2,809–3,014 Mha yr−1, which is about two-thirds of what the Food and Agriculture Organization Statistics (FAOSTAT) database reports. We discuss here the different methods for calculating the LF for livestock grazing, underscoring the need for a consistent methodology when monitoring the food LF and WF reduction goals set by the EU’s Farm To Fork Strategy.
  • A pocket-sized device enables detection of methanol adulteration in alcoholic beverages
    Item type: Journal Article
    Abegg, Sebastian; Magro, Leandro; van den Broek, Jan; et al. (2020)
    Nature Food
    Alcoholic drinks contaminated, either accidentally or deliberately, by methanol claimed at least 789 lives in 2019, mostly in Asia. Here, a palm-sized, multi-use sensor–smartphone system is presented for on-demand headspace analysis of beverages. The analyser quantified methanol concentrations in 89 pure and methanol-contaminated alcoholic drinks from 6 continents and performed accurately for 107 consecutive days. This device could help consumers, distillers, law-enforcing authorities and healthcare workers to easily screen methanol in alcoholic beverages.
  • The political economy of taxing meat
    Item type: Other Journal Item
    Fesenfeld, Lukas Paul (2023)
    Nature Food
    Taxing meat could benefit the environment, animal welfare and public health. However, such demand-side policies often face political obstacles, and politicians fear public backlash; strategic policy framing and design offer leeway.

  • Post-farmgate food value chains make up most of consumer food expenditures globally
    Item type: Journal Article
    Yi, Jing; Meemken, Eva-Marie; Mazariegos-Anastassiou, Veronica; et al. (2021)
    Nature Food
    Progress towards many United Nations Sustainable Development Goals depends on interventions in food value chains, yet data and methods have thus far limited the production of cross-nationally comparable estimates of food value chains’ magnitudes. Here we develop a standardized method and data series to estimate the distribution of consumer food expenditures between value-added activities on farms and in the post-farmgate value chain. Using data from 61 countries over 2005–2015, representing 90% of the global economy, we show that farmers receive, on average, 27% of consumer expenditure on foods consumed at home and a far lower percentage of food consumed away from home. That figure consistently falls in the 16–38% range for middle- and high-income countries and falls significantly as incomes rise. The large and growing post-farmgate food value chain merits greater attention as the world grapples with the economic, environmental and social impacts of food systems.

  • Regional conditions shape the food-energy-land nexus of low-carbon indoor farming
    Item type: Journal Article
    Weidner, Till; Yang, Aidong; Forster, Florian; et al. (2022)
    Nature Food
    Modern greenhouses and vertical farming projects promise increased food output per unit area relative to open-field farming. However, their high energy consumption calls for a low-carbon power supply such as solar photovoltaic and wind, which adds to cost and overall land footprint. Here we use geospatial and mathematical modelling to compare open-field and two indoor farming methods for vegetable production in nine city-regions chosen globally with varying land availability, climatic conditions and population density. We find that renewable electricity supply is more costly for greenhouses per unit energy demand satisfied, which is due to the greater fluctuation in their energy demand profile. However, greenhouses have a lower energy demand per unit food output, which makes them the least land-intensive option in most of the analysed regions. Our results challenge the land-savings claims of vertical farming compared with open-field production. We also show that regionalizing vegetable supply is feasible in most regions and give recommendations based on the regional context.
