Perspective: Key Considerations When Developing and Publishing Dietary Interventions for Human Clinical Trials.

ABSTRACT

A key guiding principle in the 2020-2025 Dietary Guidelines for Americans emphasizes the need for individuals to choose eating habits that allows for personal, cultural, and traditional preferences while establishing a high-quality diet. This concept becomes a daunting task given the need to reduce the consumption of foods higher in saturated fat, sodium, and/or added sugar-which are typically found in familiar, highly palatable foods most-often liked and consumed in the United States. Similarly, in nutrition intervention studies, adherence to healthier dietary patterns is typically low because of many factors, including reduced taste, flavor, and familiarity to the study foods. Increasing evidence illustrates the promising role of herbs and spices to maintain acceptability of healthier food options for nutrition interventions. This perspective article was informed by a Satellite Session presented at the American Society for Nutrition's annual meeting, Nutrition 2023, entitled, "Developing Culturally Appropriate Recipes for Human Clinical Trials," which explored several proposed best practice guidelines when developing nutrition interventions to improve dietary adherence and acceptability within clinical trials. The session also highlighted a need to include sufficient detail concerning the types and amounts of specific foods included within nutrition interventions in combination with preparation methods and study recipes, including herbs and spices, to improve intervention reproducibility and translatability for future research, dietary guidelines, and clinical practice.
