Foods for Health, a nutrition education and research program sponsored by the National Heart, Lung, and Blood Institute and Giant Food, Inc., was designed to demonstrate the feasibility of cardiovascular nutrition education at the point of purchase, specifically, in the supermarket. To evaluate the program's effectiveness, measures of consumer awareness, knowledge, and food purchases were determined before, during, and after the campaign. The program was conducted in the Washington, D.C., area, with Baltimore, Maryland, area stores serving as controls. At the conclusion of the campaign, Washington shoppers showed a significant increase in knowledge scores, while these scores decreased in the Baltimore area. The gain in correct knowledge scores for Washington shoppers compared with Baltimore shoppers was 9% for food fat and cholesterol content and 11% for the relationship between dietary fat and blood cholesterols levels. The food sales data indicate no apparent differences attributable to the intervention. Issues that might account for the lack of a significant change in food purchases, such as cost and the markets' individual sales promotion campaigns, are discussed, and recommendations for the design of future projects are made.
“健康食品”是一项由美国国立心肺血液研究所和巨人食品公司赞助的营养教育与研究项目，旨在证明在购买点，特别是在超市进行心血管营养教育的可行性。为评估该项目的效果，在活动前、活动期间和活动后分别对消费者的认知、知识和食品购买情况进行了测量。该项目在华盛顿特区地区开展，以马里兰州巴尔的摩地区的商店作为对照。在活动结束时，华盛顿的购物者知识得分显著提高，而巴尔的摩地区的这些得分却下降了。与巴尔的摩购物者相比，华盛顿购物者在食品脂肪和胆固醇含量方面的正确知识得分提高了9%，在膳食脂肪与血液胆固醇水平之间的关系方面提高了11%。食品销售数据表明，干预措施没有造成明显差异。文中讨论了可能导致食品购买量没有显著变化的问题，如成本和市场的个别促销活动，并对未来项目的设计提出了建议。
