Micronutrient deficiencies represent a largely invisible, but often devastating, form of malnutrition that is particularly prevalent among WFP's beneficiary populations already lacking sufficient food. Known effects of micronutrient deficiencies include impaired physical and mental growth among children, iron-deficiency anemia, maternal mortality, low adult labor productivity and blindness. WFP makes important, often pioneering contributions to overcoming such deficiencies through: Careful attention to micronutrients in needs assessment and ration planning, Delivering fortified foods, particularly to nutritionally-vulnerable groups, on an increasingly large scale, Promotion and use of locally-produced and fortified commodities in more than a dozen low income, food deficit countries, Advocacy for fortification at national and international policy levels. Important activities in local processing and fortification have recently taken place in countries like Zambia, Angola, Bangladesh, India, Nepal, and in the context of the regional southern Africa drought emergency. Each case demonstrates that where micronutrient deficiencies are an operational concern local fortification is possible, albeit challenging. Several ongoing assessments of the impact of such initiatives suggest important nutritional benefits. That said, challenges remain in terms of technical and managerial capacity constraints, the need for systematic compliance with procurement specifications and quality control, clearer policies on micronutrient content labeling, and the need for cash resources to support many aspects associated with local processing and fortification activities.
微量营养素缺乏是一种在很大程度上无形但往往具有毁灭性的营养不良形式,在粮食计划署那些本就缺乏足够食物的受益人群中尤为普遍。微量营养素缺乏的已知影响包括儿童身心发育受损、缺铁性贫血、孕产妇死亡、成年人劳动生产率低下以及失明。粮食计划署通过以下方式为克服此类缺乏状况做出了重要且往往具有开创性的贡献:在需求评估和配给计划中仔细关注微量营养素;越来越大规模地提供强化食品,尤其是向营养脆弱群体提供;在十几个低收入缺粮国家推广和使用当地生产的强化商品;在国家和国际政策层面倡导强化措施。最近,赞比亚、安哥拉、孟加拉国、印度、尼泊尔等国以及在南部非洲区域干旱紧急情况的背景下,都开展了当地加工和强化方面的重要活动。每个案例都表明,尽管存在挑战,但在微量营养素缺乏成为实际问题的地方,当地强化是可行的。对这些举措影响的几项正在进行的评估显示出重要的营养益处。话虽如此,在技术和管理能力限制、系统遵守采购规格和质量控制的必要性、关于微量营养素含量标签的更明确政策以及支持与当地加工和强化活动相关许多方面所需的资金资源方面,挑战依然存在。
