2010 年美国膳食指南建议 50 岁以上人群、非裔美国人和患有慢性疾病的人将钠摄入量限制在 1500 毫克/天。指南建议所有其他人每天摄入的钠摄入量低于 2300 毫克，钾摄入量低于 4700 毫克。使用基于线性规划的食物模式模型测试了满足钠和钾指南同时保持饮食营养充足的理论可行性。 2001-2002 年全国健康和营养检查调查的膳食数据被用来为 6 个年龄性别组创建优化的食物模式。线性规划模型确定了建模食物模式的钾和钠含量的边界条件，这也与其他营养目标兼容。线性规划模型还试图确定钠和钾的含量，两者都与 Na 与 K 的比率 0.49 一致，并且与现有饮食习惯的偏差最小。这 6 组食物模式是在饮食研究食品和营养数据库中所有食物的钠含量全面降低 10% 之前和之后创建的。模型分析表明，2010 年膳食指南中的钠含量与钾含量指南和营养充足的饮食不相容，即使在将所有美国食品的钠含量降低 10% 后也是如此。可行性研究应在向公众发布膳食指南之前或同时进行。
The 2010 US Dietary Guidelines recommended limiting intake of sodium to 1500 mg/d for people older than 50 years, African Americans, and those suffering from chronic disease. The guidelines recommended that all other people consume less than 2300 mg sodium and 4700 mg of potassium per day. The theoretical feasibility of meeting the sodium and potassium guidelines while simultaneously maintaining nutritional adequacy of the diet was tested using food pattern modeling based on linear programming. Dietary data from the National Health and Nutrition Examination Survey 2001-2002 were used to create optimized food patterns for 6 age-sex groups. Linear programming models determined the boundary conditions for the potassium and sodium content of the modeled food patterns that would also be compatible with other nutrient goals. Linear programming models also sought to determine the amounts of sodium and potassium that both would be consistent with the ratio of Na to K of 0.49 and would cause the least deviation from the existing food habits. The 6 sets of food patterns were created before and after an across-the-board 10% reduction in sodium content of all foods in the Food and Nutrition Database for Dietary Studies. Modeling analyses showed that the 2010 Dietary Guidelines for sodium were incompatible with potassium guidelines and with nutritionally adequate diets, even after reducing the sodium content of all US foods by 10%. Feasibility studies should precede or accompany the issuing of dietary guidelines to the public.
