Many low- and middle-income countries (LMICs) are experiencing a nutrition transition from traditional diets to high-energy, processed foods, increasing non-communicable disease risks. Digitalization of food systems plays a significant role in shaping this transition. This paper investigates the...

Community supported agriculture (CSA) is a format for provisioning food, usually vegetables, where consumers are involved, to various degrees, in the production process. In this study of survey data, we explore differences between CSAs in Norway and the UK in terms of organisational models and...

Background Obesity has become major public health problem around the world. Lifestyle interventions, Pharmacotherapy and bariatric surgery are the common intervention to reduce weight in clinical practice. This study aims to conduct an economic evaluation of Duodenal-Jejunal Bypass Sleeve (DJBS)...

Meat consumption has come under scrutiny due to its significant ecological footprint. Understanding the determinants of meat consumption is crucial for designing effective interventions to promote sustainable diets. Thus, using results from the representative survey conducted in Latvia, in 2023...

Over the last decade, there has been a growing demand for tools to support sustainable healthy lifestyles, including food choices. Through a survey, this study examined the influence of environmental nutrition information conveyed with aids such as nudges and traffic light labels through a...

We propose a theoretical model to study individual lifestyle choices related to calorie intake and physical activity, depending on personal fitness level and body weight. The model builds on the rational eating literature and can generate a variety of behaviors that are consistent with the...

This paper examines the link between dynamically inconsistent time preferences and individual food waste behavior. Food waste is conceptualized as unintentional outcome of choices along the food consumption chain. Capitalizing on a nationally representative longitudinal survey from Germany, we...

This paper uses restricted-access data from the Behavioral Risk Factor Surveillance System Survey to assess whether the sugar-sweetened beverage (SSB) tax levied in Seattle in 2018 led to declines in body mass index (BMI) and the rate of obesity. We implement an event-study design which compares...

This Knowledge Note presents two sets of analytical work to further our understanding of the links between public support in the agrifood sector and healthy diets. While the analytical work here is mostly suggestive, it paves the way for more in-depth research to unpack the relationship of...

Understanding when and why nudges work is crucial for designing interventions that consistently and reliably change behaviour. This paper explores the relationship between decision-making speed and the effectiveness of two nudges – carbon footprint labelling and menu repositioning – aimed at...

Purpose This study analyzes what type of influencer - microcelebrity or microinfluencer - is best suited to promoting healthy food brands and how that influence depends on consumers' healthy lifestyles. Design/methodology/approach An empirical study with a real healthy food brand was developed...

Most households in rural Africa are involved in smallholder farming, but off-farm employment is an important additional income source for many. Previous research has analyzed links between off-farm employment and wellbeing, but mostly at the household level, not considering that household...

This paper examines the link between dynamically inconsistent time preferences and individual food waste behavior. Food waste is conceptualized as unintentional outcome of choices along the food consumption chain. Capitalizing on a nationally representative longitudinal survey from Germany, we...

The consumption of whole grains has several health benefits, however, most US consumers - including young adults - do not meet the recommended consumption intake. To understand the underlying factors affecting the intention and consumption of whole grain pasta, a survey based on the Theory of...

This paper explores the relationship between decision-making speed and the effectiveness of two nudges - carbon footprint labelling and menu repositioning - aimed at encouraging climate-friendly food choices. Building on Kahneman's dual-process theory of decision-making, we examine whether these...

Fish stomach content is a compelling data source, as stomachs can provide information about diet of predators, distribution of prey fish, predator-prey preference or changes in diet over time. For instance, stomach samples have historically been used to inform the natural mortality of stock...

Interventions to decrease meat consumption are often only implemented for short periods of time, and it is unclear how they might have lasting effects. We combine student canteen consumption (over 270, 000 purchases made by over 4, 500 guests) and survey data (N 800) to study how a one-month...

Mitigating climate change requires large and, by historical standards, rapid changes to policy, business processes and individual behaviour. This report examines awareness of and perceived difficulty with individual behaviour change with respect to two actions associated with high levels of...

Resource scarcity, the effects of climate change, food insecurity, and health issues related to dietary choices have prompted policymakers to develop new strategies to encourage populations to opt for healthy and sustainable (HS) diets. In this context, nudging strategies are promising tools to...

Regulation of meat consumption appears to be a relevant public policy to limit diet-related greenhouse gas emissions. However, the real impact of such a policy (e.g., tax) on human health and nutrition remains uncertain, especially for underprivileged individuals. Based on representative data...

Rice-aquaculture is promoted in many countries as a system that could simultaneously improve land and water productivity and household diets and nutrition. However, studies evaluating the effects of rice-aquaculture adoption on household diets do not yet exist. Here, we address this research...
