The Dietary Guidelines for Americans 2010 provides authoritative advice on what Americans should eat to stay healthy. These guidelines provide a quantitative recommendation to consume 250 mg/d of (n-3) fatty acids (also known as omega-3 fatty acids). To achieve this goal, Americans would need to more than triple the amount of EPA and DHA currently consumed. This paper assessed the cost implications of increased levels of EPA and DHA from marine and nonmarine food sources using data from the 2007-2008 NHANES, USDA nutrient data base, and the USDA Center for the Nutrition Policy and Promotion food price data. Stearidonic acid (SDA)-enhanced soybean oil is a lower cost alternative to commonly consumed marine food as a source of EPA. In addition, given that SDA-enhanced soybean oil is intended to be used as an ingredient in a variety of products, this may enable consumers to increase consumption of EPA through commonly consumed foods.
《美国人的饮食指南 2010》就美国人保持健康应摄入的营养成分提供了权威性建议。该指南推荐每日摄入 250 毫克(n-3)脂肪酸(亦称欧米伽-3 脂肪酸)。为实现这一目标,美国人需要将 EPA 和 DHA 的摄入量增加两倍以上。本文利用 2007-2008 年国家健康和营养调查(NHANES)、美国农业部营养数据库以及美国农业部营养政策和推广中心食品价格数据,评估了从海洋和非海洋食物中增加 EPA 和 DHA 含量的成本影响。通过强化 Stearidonic 酸(SDA)的大豆油作为 EPA 的常见海洋食物来源的一种更廉价替代品,具有成本效益。此外,鉴于 SDA 强化大豆油旨在作为各种产品的成分,这可能使消费者能够通过常见食物增加 EPA 的摄入量。
