This paper proposes an interdisciplinary framework that combines different methodologies to measure the risks and benefits related to dietary patterns and to assess the impact of possible regulations influencing food consumption. First, we briefly review the relevant methodologies within the field of health-economics. Based on the gaps identified in this review, we proposed a framework allowing an integrated application of quantitative health impact assessment (HIA) using disability‒adjusted life year (DALY) and cost‒benefit analysis (CBA) calibrated with measures capturing consumers preferences, such as willingness to pay (WTP) and purchase intent (PI). We applied the framework to a case study focusing on the lentil market to test the feasibility of the methodology and we discuss options for model extensions and their limits. We estimated annual DALYs attributable to an increase in the consumption of lentils (scenarios with or without food substitutions), and measured welfare variations and the impact of regulatory instruments, such as subsidies and taxes. Results showed that a hypothetical increase of 30% or more in the consumption of lentils would not be socially accepted as an immediate market reaction, even if lentils are considered a food substitute to reduce the consumption of unprocessed red meat. Our framework is useful to streamline regulatory interventions as it supports the evaluation of impacts of various regulatory instruments, relevant for policies governing consumers' awareness or impacting consumers' choice via incentives. Furthermore, it provides a starting point for further interdisciplinary discussions on holistic assessment supporting food systems change.
本文提出了一个跨学科框架,该框架结合了不同方法来衡量与饮食模式相关的风险和益处,并评估可能影响食品消费的法规的影响。首先,我们简要回顾了健康经济学领域的相关方法。基于此次回顾中发现的差距,我们提出了一个框架,允许综合应用使用伤残调整生命年(DALY)的定量健康影响评估(HIA)和通过诸如支付意愿(WTP)和购买意愿(PI)等反映消费者偏好的指标校准的成本效益分析(CBA)。我们将该框架应用于一个以小扁豆市场为重点的案例研究,以测试该方法的可行性,并讨论模型扩展的选项及其局限性。我们估计了因小扁豆消费增加(有或无食物替代的情景)导致的年度DALYs,并衡量了福利变化以及补贴和税收等监管工具的影响。结果表明,即使小扁豆被视为减少未加工红肉消费的食物替代品,小扁豆消费假设性地增加30%或更多作为即时市场反应也不会被社会接受。我们的框架有助于简化监管干预措施,因为它支持评估各种监管工具的影响,这些影响与管理消费者意识或通过激励措施影响消费者选择的政策相关。此外,它为关于支持食品系统变革的整体评估的进一步跨学科讨论提供了一个起点。
