Lettuce is one of the most widely consumed vegetables in the world, commonly eaten fresh in salads, sandwiches, wraps, and as a garnish in various dishes. Consequently, it is a very promising vehicle to deliver vitamins, such as folate (vitamin B9), to a specific population using biofortified varieties generated by conventional or molecular breeding. A new genetically modified lettuce was generated with increased folate content. However, some issues related to public perception regarding this technology should still be evaluated. The aim of this study was to analyze whether consumers are willing to accept a folate-biofortified GM lettuce that could become available to the Brazilian market. A questionnaire involving several issues regarding lettuce consumption was answered by 2,391 people from almost all Brazilian states. When informed that the folic acid biofortified lettuce is a transgenic plant, 46.1% of respondents stated that they would eat it and 30.5% stated that it would be a possibility. This study demonstrated that if there is any explanation regarding the advantage in relation to the use of biotechnology, like enrichment with folic acid, the number of people who accept it increases.
生菜是世界上消费最广泛的蔬菜之一，通常在沙拉、三明治、卷饼中新鲜食用，或作为各种菜肴的配菜。因此，它是一种非常有前途的载体，可以使用传统或分子育种产生的生物强化品种向特定人群输送维生素，如叶酸（维生素 B9）。一种新的遗传修饰生菜的叶酸含量增加了。然而，关于这项技术的一些与公众认知相关的问题仍有待评估。本研究旨在分析消费者是否愿意接受一种叶酸生物强化的 GM 生菜，这种生菜可能会进入巴西市场。一个涉及生菜消费的几个问题的问卷由来自巴西几乎所有州的 2391 人回答。当被告知富含叶酸的生菜是转基因植物时，46.1%的受访者表示他们会吃，30.5%的受访者表示这是一种可能性。这项研究表明，如果有任何关于使用生物技术（如富含叶酸）的优势的解释，那么接受它的人数就会增加。
