Because excessive dietary sodium intake is a major contributor to hypertension, a reduction in dietary sodium has been recommended for the US population. Using the National Health and Nutrition Examination Survey (NHANES) 2007-2010 data, we estimated current sodium intake in US population ethnic subgroups and modeled the potential impact of a new sodium reduction technology on sodium intake.
NHANES 2007-2010 data were analyzed using The National Cancer Institute method to estimate usual intake in population subgroups. Potential impact of SODA-LO® Salt Microspheres sodium reduction technology on sodium intake was modeled using suggested sodium reductions of 20-30% in 953 foods and assuming various market penetrations. SAS 9.2, SUDAAN 11, and NHANES survey weights were used in all calculations with assessment across age, gender and ethnic groups.
Current sodium intake across all population subgroups exceeds the Dietary Guidelines 2010 recommendations and has not changed during the last decade. However, sodium intake measured as a function of food intake has decreased significantly during the last decade for all ethnicities. "Grain Products" and "Meat, Poultry, Fish, & Mixtures" contribute about 2/3rd of total sodium intake. Sodium reduction, using SODA-LO® Salt Microspheres sodium reduction technology (with 100% market penetration) was estimated to be 185-323 mg/day or 6.3-8.4% of intake depending upon age, gender and ethnic group.
Current sodium intake in US ethnic subgroups exceeds the recommendations and sodium reduction technologies could potentially help reduce dietary sodium intake among those groups.
由于过量的膳食钠摄入是高血压的主要促成因素，因此建议美国人群减少膳食钠摄入。利用2007 - 2010年美国国家健康与营养检查调查（NHANES）的数据，我们估算了美国人群各亚组当前的钠摄入量，并模拟了一种新的钠减少技术对钠摄入量的潜在影响。
使用美国国家癌症研究所的方法分析2007 - 2010年NHANES的数据，以估算人群亚组的通常摄入量。采用SODA - LO®盐微球钠减少技术，假设953种食物的钠减少量为20% - 30%，并考虑各种市场渗透率，模拟其对钠摄入量的潜在影响。所有计算均使用SAS 9.2、SUDAAN 11以及NHANES调查权重，并按年龄、性别和种族进行评估。
所有人群亚组当前的钠摄入量均超过《2010年膳食指南》的建议，且在过去十年中没有变化（然而，以食物摄入量为函数衡量的钠摄入量在过去十年中对所有种族而言均显著下降）。“谷物制品”和“肉类、家禽、鱼类及混合食品”约占总钠摄入量的三分之二。据估计，采用SODA - LO®盐微球钠减少技术（市场渗透率为100%），根据年龄、性别和种族的不同，钠减少量为每天185 - 323毫克，即摄入量的6.3% - 8.4%。
美国各亚组当前的钠摄入量超过了建议量，钠减少技术可能有助于降低这些人群的膳食钠摄入量。
