Food value chains (FVC) have become an important framework for the assessment of interventions to improve nutritional outcomes during the past decade, and recent literature indicates considerable agreement about FVC importance and potential impact pathways. Despite the usefulness of the FVC framework, the majority of studies reviewed provide only conceptual models or descriptive analyses of linkages with nutrition, limiting their usefulness for quantitative assessment of intervention impacts. Fewer than five studies of 113 reviewed measure the impacts of FVC interventions on nutritional outcomes or provide study protocols for that purpose. In addition to randomized controlled trials, comparative analysis and systems modeling methods will provide relevant evidence about the effectiveness of FVCs for improvement of nutrition.
食品价值链（FVC）在过去十年中已成为评估改善营养结果干预措施的重要框架，最近的文献表明，人们对 FVC 的重要性及其潜在影响途径有相当程度的共识。尽管 FVC 框架很有用，但所审查的大多数研究仅提供了与营养相关的概念模型或描述性分析，限制了它们在定量评估干预措施影响方面的有用性。在所审查的 113 项研究中，只有不到五项研究衡量了 FVC 干预措施对营养结果的影响，或为此目的提供了研究方案。除了随机对照试验外，比较分析和系统建模方法将为改善营养的 FVC 的有效性提供相关证据。
