Scant evidence is available on the relationship between preferences for organic, local, sustainable, and nonprocessed foods (ie, alternative food production practices) and dietary quality. This cross-sectional study examined the characteristics and dietary behaviors (eg, consumption of fruits, vegetables, fast food) of young adults who reported placing low, moderate, or high importance on alternative food production practices. A diverse sample of 1,201 students at a 2-year community college and a 4-year public university in the Twin Cities, MN, completed the Student Health and Wellness Study survey in spring 2010. χ(2) tests examined differences in attitudes across demographic characteristics. Linear regression adjusted dietary intake across attitudes. About half (49%) of young adults placed moderate to high importance on alternative production practices, and few demographic differences across attitudes were found. Young adults who placed high importance on alternative production practices consumed 1.3 more servings of fruits and vegetables (P<0.001), more dietary fiber (P<0.001), fewer added sugars (P<0.001), fewer sugar-sweetened beverages (P=0.001), and less fat (P=0.025) than those who placed low importance on these practices. Young adults who placed high importance on alternative food production practices also consumed breakfast approximately 1 more day per week and fast food half as often as those who placed low importance on these practices (P<0.001). Study findings suggest that nutrition messaging around social and environmental implications of food production practices may be well received by this age group. Experimental studies are needed to investigate whether attitudes toward alternative production practices can be manipulated to improve dietary quality.
关于人们对有机食品、本地食品、可持续食品和非加工食品(即替代食品生产实践)的偏好与饮食质量之间的关系,目前相关证据有限。本横断面研究调查了报告对替代食品生产实践低度、中度或高度重视的年轻成年人的特征和饮食行为(如水果、蔬菜、快餐的消费)。明尼苏达州双子城的一所 2 年制社区学院和一所 4 年制公立大学的 1201 名学生参加了 2010 年春季的“学生健康与健康研究”调查。卡方检验用于检验人口统计学特征下的态度差异。线性回归根据态度调整饮食摄入量。大约一半(49%)的年轻人对替代生产实践非常重视,而且态度之间的人口统计学差异很小。高度重视替代生产实践的年轻人比低度重视的年轻人多吃 1.3 份水果和蔬菜(P<0.001)、更多膳食纤维(P<0.001)、更少添加糖(P<0.001)、更少含糖饮料(P=0.001)和更少脂肪(P=0.025)。高度重视替代食品生产实践的年轻人每周大约多吃 1 天早餐,而且吃快餐的频率比低度重视这些实践的年轻人低一半(P<0.001)。研究结果表明,围绕食品生产实践的社会和环境影响的营养信息可能会受到这一年龄组的欢迎。需要进行实验研究,以调查对替代生产实践的态度是否可以被操纵以改善饮食质量。
