Food is a nodal point for multiple interconnected issues and concerns. The categories below highlight a few of the most critical, including food security and nutrition, water, governance and policy, and health issues.
Two letters in the journal Cell Metabolism respond to the recent paper by Hall et al., Ultra-Processed Diets Cause Excess Calorie Intake and Weight Gain: An Inpatient Randomized Controlled Trial of Ad Libitum Food Intake. See our Building Block on disagreements about ultra-processed foods here: What is ultra-processed food? And why do people disagree about its utility as a concept?
Fisheries often discard large quantities of unwanted catches at sea, but policies are being brought in to limit such discards. According to this paper, Northern gannets (seabirds) rely more on fishery discards in years when there are shortages in their natural prey (mainly mackerel) - shortages that may be due to pressure from fisheries. The paper argues that fishery discards are not an adequate substitute for natural prey.
This systematic review of taxes on sugar-sweetened beverages (SSBs) finds that the taxes are associated with a decrease in the amount of sugar-sweetened beverages that are bought and consumed. A 10% tax lead to a 10% decrease in purchase and intake levels, on average, although there was considerable variation between results in different locations.
This book examines the impacts that climate change is expected to have on food security and also explores the contribution to food security that could come from wild relatives of food crops.
This report from the UK’s Triodos Bank calls for a radical overhaul of the food system with a focus on environmental sustainability, healthy diets, and fair pay for farmers.
This report from UK supermarket Sainsbury’s sets out predictions for how the food system might be in the years 2025, 2050 and 2169. Near-term predictions include milk made from algae, and increased numbers of flexitarian eaters, while long-term predictions include farming in inhospitable landscapes such as deserts or Mars, and personal microchip implants that tell us exactly what nutrition we need.
This paper presents a newly developed open-source system for precision agriculture in lettuce production. The system, known as AirSurf, uses a lightweight manned aircraft to gather images of lettuce fields, then a deep learning algorithm assesses the state of the lettuce crops on a number of characteristics, including lettuce size and number per field.
According to this paper, households in the Netherlands wasted 41kg of solid food per person in 2016 - a 15% decline since 2010. Furthermore, 57 litres per person of potable liquids such as coffee, tea and milk are disposed of via the sink or toilet each year. Rice, bread, pasta, vegetables and pastries are among the food types most likely to be wasted (as a percentage of purchased quantity).
This paper sets out a new method to account for nutrition in the functional unit of life cycle assessments of single foods. The method accounts for the wider dietary context of each food type, which is found to affect the results relative to using either mass as a functional unit, or another nutrient-based functional unit that does not consider the dietary context.
This perspective piece argues that the definition of protein quality should be updated to reflect both environmental and nutritional concerns.
A joint investigation by the Guardian newspaper, Channel 4 News and the UK’s non-profit Bureau of Investigative Journalism has found that halving ammonia emissions from farms in the UK could save thousands of lives each year. However, a loophole in regulations means that ammonia emissions from beef and dairy farms do not have to be monitored.
This report from the European Academies Science Advisory Board outlines the connections between climate change and human health in Europe, recommends integrating health concerns into climate mitigation strategies, and suggests areas of priority for further research.
This report from US management consultancy AT Kearney identifies trends in the cultured meat and meat replacement sectors. It estimates that, by 2040, cultured meat and novel vegan meat replacements will together account for a greater market share than conventional meat.
This investor briefing from UK responsible investment charity ShareAction introduces the topic of childhood obesity and sets out the opportunities and risks it poses to investment portfolios.
This report from environmental NGO Greenpeace International documents the efforts of over 50 companies to demonstrate their progress towards ending deforestation by disclosing their cattle, cocoa, dairy, palm oil, pulp and paper and soya suppliers. No company was able to demonstrate significant action on eliminating deforestation, while those companies that do publish their suppliers all source from producers involved in deforestation.
According to this study of farmland birds in Finland, bird abundance is positively correlated with the nearby presence of organic animal farms, as well as the percentage of nearby field cover and the presence of natural grasslands.
