背景：遵守饮食指南意味着在日常饮食中加入多种食物和营养素，以较少或较大的量摄入。可行性研究可以帮助确定一个营养指南是否与另一个营养指南相冲突。对于一半的美国人来说，2010年的钠饮食指南被设定为1500 mg/d。目的：测试1500 mg/d的钠目标与营养充足的饮食的兼容性。方法：2010年进行的分析使用了美国联邦营养成分和饮食摄入量数据库，使用线性规划技术为六个性别年龄组建立了食物模式的模型。食物模式的设计符合27种营养素的营养标准，因为平均钠含量从2001-2002年国家健康和营养调查(NHANES)中观察到的水平逐渐降低到1500毫克/天。结果：对于50岁的成年人来说，2300毫克/天的钠目标与营养充足的饮食是一致的，但需要与当前的饮食模式有很大的偏差。每天1500毫克的目标是不可行的，也没有得到任何数学解。理论上可以达到的营养充足的最低钠食物模式是果汁、坚果和种子的含量非常高，但谷物和肉类的钠含量很低。结论：遵守2010年的钠盐指南将要求与当前的饮食行为有很大的偏差和/或深刻地改变美国的食品供应。(Am J Prev Med 2012；42(2)：174-179)(C)2012年美国预防医学杂志
Background: Compliance with dietary guidelines means incorporating multiple foods and nutrients into everyday diets, to be consumed in smaller or larger amounts. Feasibility studies can help determine whether one nutrient guideline comes into conflict with another. For one half of the U. S. population, the 2010 dietary guidelines for sodium were set at 1500 mg/d.Purpose: To test the compatibility of the 1500 mg/day sodium goal with nutrient-adequate diets.Methods: Analyses, conducted in 2010, used U. S. federal nutrient composition and dietary intake databases to create modeled food patterns for six gender-age groups using linear programming techniques. The food patterns were designed to meet nutritional standards for 27 nutrients as the mean sodium content was progressively reduced from levels observed in the 2001-2002 National Health and Nutrition Examination Survey (NHANES) down to 1500 mg/day.Results: For adults aged < 50 years, the 2300 mg/day sodium goal was consistent with nutrient-adequate diets but required large deviations from current eating patterns. The 1500 mg/day goal was not feasible and no mathematical solution was obtained. The lowest-sodium food patterns that were nutrient-adequate and theoretically achievable were very high in fruit juices, nuts, and seeds but were low in grains and meats.Conclusions: Compliance with the 2010 sodium guidelines will require large deviations from current eating behaviors and/or a profound modification of the U. S. food supply. (Am J Prev Med 2012; 42(2): 174-179) (C) 2012 American Journal of Preventive Medicine
