背景资料:钾(K)是人体中参与血压调节、肌肉收缩和神经传递的必需矿物质和主要细胞内电解质。钾的主要饮食来源包括水果和蔬菜,淀粉类根和块茎,以及全谷物。本研究的目的是评估和报告:(i)全球国家粮食系统中钾的充足性,(ii)量化食物组的贡献,以及(iii)探索1961-2017年期间的时空趋势。研究方法:结合1961-2017年的食物供应和人口统计数据、钾组成和钾需要量数据,估算了国家、地区、大陆和全球人均膳食钾供应量(DSK)、钾充足摄入量(AIK)和钾充足率(KSR)。结果和讨论:全球平均值± SD。DSK(mg人均-1 d-1)从1961年的2984 ± 915增加到2017年的3796 ± 1161。不同地理区域和不同年份之间的DSK差异很大,东亚地区的增幅尤其大,DSK从<3000 to >5000 mg/人-1天-1增加。根和块茎是钾的最大膳食来源,在大多数地区提供高达80%的DSK。在全球范围内,在整个57年期间,基于2006年医学研究所AIK建议的人口加权KSR &lt;1,而基于2019年美国国家科学院和2016年欧盟AIK建议的人口加权KSR&gt;1。KSR ≥ 1表示DSK充分,KSR &lt; 1不表示钾缺乏风险。结论:由于缺乏K的推荐每日摄入量(RDA),本研究使用了DSK:AIK的比例(即,KSR)来评估膳食钾充足率。因此,膳食钾充足率的估计对所使用的AIK参考值高度敏感,并且基于不同的机构和年份,这差异很大。为了量化膳食钾缺乏的风险,弥合数据差距以建立钾的RDA应该是全球研究的优先事项。
Background: Potassium (K) is an essential mineral and major intracellular electrolyte involved in the regulation of blood pressure, muscle contraction and nerve transmission in humans. Major dietary sources of K include fruits and vegetables, starchy roots and tubers, and whole grains. The aim of this study was to assess and report: (i) the sufficiency of K in national food systems globally, (ii) to quantify the contribution from food groups, and (iii) to explore spatial and temporal trends in the period of 1961–2017. Methods: Food supply and demography (1961–2017), K composition and K requirement data were combined to estimate per capita human dietary supplies of potassium (DSK), adequate intake of K (AIK) and K sufficiency ratio (KSR) at national, regional, continental and global levels. Results and Discussion: Globally, the mean ± SD. DSK (mg capita−1 d−1) increased from 2984 ± 915 in 1961 to 3796 ± 1161 in 2017. There was a wide range in DSK between geographical regions and across years, with particularly large increases in east Asia, where DSK increased from <3000 to >5000 mg capita−1 day−1. Roots and tubers contributed the largest dietary source of K, providing up to 80% of DSK in most regions. At the global level, throughout the 57-year period, the population-weighted KSR was <1 based on the 2006 Institute of Medicine AIK recommendation, while it was >1 based on the 2019 National Academies of Science and the 2016 European Union AIK recommendation. While KSR ≥ 1 shows sufficiency of DSK, KSR < 1 does not indicate K deficiency risk. Conclusion: Due to the absence of a Recommended Daily Allowance (RDA) for K, this study used the ratio of DSK:AIK (i.e., KSR) to assess dietary K sufficiency. Estimates of dietary K sufficiency are, therefore, highly sensitive to the AIK reference value used and this varied greatly based on different institutions and years. To quantify the risk of dietary K deficiency, bridging the data gap to establish an RDA for K should be a global research priority.
