The purpose of this study was to assess whether the availability of a product sample of an unfamiliar low-fat or fruit and vegetable products stimulates choice for this product among food neophobic young adults. The study had a 2 (experimental vs. control group) by 4 (low-fat bread spread, low-fat cheese, fruit juice, fruit and vegetable juice) between subjects design with a pre-and post-experiment questionnaire. The study was conducted in restaurant rooms of several educational institutions in the Netherlands among a convenience sample of 197 food neophobic young adults aged 17-25 years. A small bite or sip-sized sample of the target product was provided as an intervention. The effect measure was choice of either an unfamiliar healthful food product or a traditional food product. Offering a sample of an unfamiliar healthful food product resulted in 51% of the participants in the experimental group choosing this product vs. 36.4% in the control group. Providing food product samples seems to be a promising strategy in healthy diet promotion programs for food neophobic young adults to increase first-time trial of unfamiliar low-fat and fruit and vegetable products.
本研究旨在评估提供一种不熟悉的低脂或果蔬产品的样品是否会刺激食物厌恶型年轻成年人选择这种产品。研究采用 2（实验组与对照组）×4（低脂面包酱、低脂奶酪、果汁、果蔬汁）被试间设计，并在实验前后采用问卷进行调查。该研究在荷兰几所教育机构的餐厅房间内进行，方便选取了 197 名 17-25 岁的食物厌恶型年轻成年人作为研究对象。实验干预是提供目标产品的一小口或一小口大小的样品。衡量指标是选择不熟悉的健康食品或传统食品。提供不熟悉的健康食品样品后，实验组有 51%的参与者选择了这种产品，而对照组只有 36.4%。提供食品样品似乎是针对食物厌恶型年轻成年人的健康饮食推广计划中的一种很有前途的策略，可增加他们首次尝试不熟悉的低脂和果蔬产品。
