Abstract：
Poor nutrition is one of the leading causes of non-communicable diseases (NCDs), especially in the WHO Region of the Americas (AMRO). In response, international organisations recommend front-of-pack nutrition labelling (FOPNL) systems that present nutrition information clearly to help consumers make healthier choices. In AMRO, all 35 countries have discussed FOPNL, 30 countries have formally introduced FOPNL, eleven have adopted FOPNL, and seven countries (Argentina, Chile, Ecuador, Mexico, Peru, Uruguay and Venezuela) have implemented FOPNL. FOPNL has gradually spread and evolved to better protect health by increasingly adopting larger warning labels, contrasting background devices for better salience, using \"excess\" instead of \"high in\" to improve efficacy, and adopting the Pan American Health Organization\'s (PAHO) Nutrient Profile Model to better define nutrient thresholds. Early evidence illustrates successful compliance, decreased purchases and product reformulation. Governments still discussing and waiting to implement FOPNL should follow these best practices to help reduce poor nutrition related NCDs. Translated versions of this manuscript are available in Spanish and Portuguese in the supplementary material.
摘要：
营养不良是导致非传染性疾病的主要原因之一，特别是在世卫组织美洲区域(AMRO)。作为回应,国际组织推荐包装前营养标签（FOPNL）系统，该系统清楚地提供营养信息，以帮助消费者做出更健康的选择。在AMRO,所有35个国家都讨论过FOPNL,30个国家正式推出FOPNL,11人采用了FOPNL，和七个国家(阿根廷，智利,厄瓜多尔,墨西哥,秘鲁,乌拉圭和委内瑞拉）已实施FOPNL。FOPNL已经逐渐传播和发展，通过越来越多地采用更大的警告标签来更好地保护健康。对比背景设备以获得更好的显著性，使用“过量”而不是“高”来提高疗效，并采用泛美卫生组织（泛美卫生组织）的营养概况模型来更好地定义营养阈值。早期证据表明成功合规，减少采购和产品重新配方。仍在讨论和等待实施FOPNL的政府应遵循这些最佳做法，以帮助减少与营养不良有关的非传染性疾病。该手稿的翻译版本在补充材料中以西班牙语和葡萄牙语提供。
