Our global food system lacks the critically needed micronutrients to meet the daily requirements of the most at-risk populations. Diets also continue to shift toward unhealthy foods, including the increased intake of salt. While most countries exceed the WHO's recommended levels, sodium does play an essential physiological role. Table salt and other salt-containing condiments, such as bouillon, also have cultural importance, as they are used to enhance the flavor of foods cooked at home. Given their universal consumption across income classes and both urban and rural populations, these condiments are an integral part of the food system and should, therefore, be part of its transformation. Fortification of salt and salt-containing condiments can play a catalytic role in the delivery of population-wide nutritional and health benefits. With relatively consistent levels of intake across the population, these condiments hold high potential for delivering micronutrients beyond iodine while also reducing concerns related to high micronutrient intake, particularly so in countries where the industries are relatively consolidated. As a flexible and complementary strategy to an evolving food system, fortification levels can also be adjusted over time to ensure micronutrient delivery targets continue to be achieved as the system improves, whether through lower intakes of sodium in line with WHO recommendations, enhanced consumption of nutrient-dense foods, and/or broader adoption of biofortified crops. Future areas of innovation are required to realize this vision, including developing affordable salt substitutes to meet cost requirements of consumers in low-and middle-income countries, improving the stability and bioavailability of the micronutrients in condiments so that delivery targets can be reached without affecting sensory attributes, and the development of efficient systems for monitoring population intake and micronutrient status to inform fortification program design and management. Rather than being considered antithetical to the transformation, multiply-fortified salt and bouillon can strengthen our ability to meet the cultural, sensory, nutritional, and health needs of an evolving food system.
我们的全球食物系统缺乏满足高危人群日常需求的关键微量营养素。饮食也继续向不健康的食物转变,包括增加盐的摄入量。虽然大多数国家的盐摄入量超过了世界卫生组织的建议水平,但钠确实在生理上起着重要作用。食盐和其他含盐分的调味料,如肉汤,也具有文化意义,因为它们被用来增强在家烹饪的食物的味道。鉴于这些调味料在收入阶层、城乡人口中普遍消费,它们是食物系统不可或缺的一部分,因此应该成为其转型的一部分。盐和含盐分的调味料的强化可以在提供全民营养和健康益处方面发挥催化作用。由于人群中摄入量相对一致,这些调味料在提供除碘以外的微量营养素方面具有很高的潜力,同时还可以减少与高微量营养素摄入相关的担忧,特别是在那些行业相对集中的国家。作为一个不断发展的食物系统的灵活和补充策略,强化水平也可以随着时间的推移进行调整,以确保随着系统的改善,继续实现微量营养素的输送目标,无论是通过遵循世界卫生组织建议降低钠的摄入量,增加营养密集型食物的消费,还是更广泛地采用生物强化作物。为了实现这一愿景,需要创新未来领域,包括开发负担得起的盐替代品,以满足低收入和中等收入国家消费者的成本要求,提高调味料中微量营养素的稳定性和生物利用度,在不影响感官属性的情况下达到输送目标,以及开发有效的系统来监测人群的摄入量和微量营养素状况,为强化计划设计和管理提供信息。多重强化盐和肉汤不仅不会对转型产生反作用,反而可以增强我们满足不断发展的食物系统的文化、感官、营养和健康需求的能力。
