This study was designed to examine the effects of various kinds of information on willingness to ingest novel foods in individuals varying in the extent to which they reported that nutritional concerns affected their food choices. Male and female volunteers ranging in age from 10 to 79 (N = 401), saw six familiar and six novel foods, and received no information, taste likability information, general nutrition information, or specific nutrition information about the whole set of foods. They rated their willingness to taste each food, with the clear implication that their willingness ratings would determine which foods they would taste later in the study. On a separate questionnaire, they also rated the factors influencing their food everyday choices, and these ratings were used to compute an "importance of nutrition" score for each individual. Results indicated that older subjects were generally more willing to try novel foods than younger ones, that general nutrition information was effective for high school and college students, and that specific nutrition information was influential for young adults. It was also found that general nutrition information increased willingness to taste novel food in subjects for whom nutrition is important and decreased such willingness in subjects for whom nutrition is not important.
本研究旨在考察各类信息对不同个体摄入新食物意愿的影响,这些个体报告营养问题影响其食物选择的程度各不相同。年龄在10至79岁之间的401名男女志愿者,观看了六种熟悉的食物和六种新食物,并分别接受了关于这组食物的无信息、口味喜好信息、一般营养信息或特定营养信息。他们对品尝每种食物的意愿进行评分,这显然意味着他们的意愿评分将决定他们在后续研究中会品尝哪些食物。在一份单独的问卷中,他们还对影响其日常食物选择的因素进行评分,这些评分用于计算每个个体的“营养重要性”得分。结果表明,年长的受试者通常比年轻受试者更愿意尝试新食物;一般营养信息对高中生和大学生有效;特定营养信息对年轻人有影响。研究还发现,一般营养信息会增加营养对其很重要的受试者品尝新食物的意愿,而降低营养对其不重要的受试者的这种意愿。
