In 1975 a national sample of consumers was questioned about their knowledge of nutrition, beliefs about food, and their shopping behavior. Findings indicate a particular need for education related to facts about iron, thiamin, riboflavin, and vitamins A and D. Consumers with low knowledge tended to have less education, lower income, and less prestigious occupations. Of these variables, educational achievement level had the strongest association to low nutrition knowledge. Using an index based on the three socioeconomic variables, low knowledge was more often present among the male and older shoppers, with age having the stronger association. Association of the three indices of nutrition knowledge, food beliefs, and reported shopping behavior were found to be positive and linear.
1975年，对全国范围内的消费者样本进行了调查，询问他们的营养知识、对食物的看法以及购物行为。调查结果表明，特别需要开展有关铁、硫胺素、核黄素以及维生素A和D相关知识的教育。营养知识匮乏的消费者往往受教育程度较低、收入较少且职业声望较低。在这些变量中，教育成就水平与低营养知识的关联最为紧密。根据这三个社会经济变量构建的指数显示，男性和年龄较大的购物者中营养知识匮乏的情况更为常见，年龄与低营养知识的关联更为紧密。研究发现，营养知识、食物看法和报告的购物行为这三个指数之间的关联是正向且呈线性的。
