Using herbs and spices to improve dietary quality in college students

Assessing the Feasibility and Potential Efficacy of Herbs and Spices for Improving Dietary Quality and Adherence to the Dietary Guidelines for Americans in College Students With Poor Dietary Quality: A Pilot Study

NA · University of Nevada, Las Vegas · NCT07082348

This pilot will try using an herbs-and-spices nutrition program with college students who have poor diets to see if it improves their dietary quality, gut health, and cardiometabolic measures.

What this trial studies

This single-arm pilot will enroll 30 college students with poor dietary quality in a 6-week Herbs and Spices Nutrition Program (HSNP) delivered in two cohorts of 15 at UNLV. The intervention combines Dietary Guidelines-focused nutrition education with practical strategies for incorporating herbs and spices into regular meals. Investigators will measure feasibility and acceptability, pre- and post-intervention dietary intake and diet-quality scores, cardiometabolic markers, and gut microbiome measures. The study will also document implementation barriers to inform a larger, controlled trial if results are promising.

Who should consider this trial

Good fit: College students aged 18–39 with a Rapid Prime Diet Quality Score of 12 or below, BMI between 18.5 and 40 kg/m2, who can maintain current lifestyle habits and attend in-person visits at UNLV are ideal candidates.

Not a fit: People with allergies to herbs or spices, significant gastrointestinal disease, current antibiotic or probiotic use, unstable chronic metabolic conditions, recent major cardiac events, or who are pregnant or nursing are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, the program could help college students improve their dietary quality and potentially produce modest improvements in gut microbiome composition and cardiometabolic risk markers.

How similar studies have performed: There is limited prior work specifically testing herbs-and-spices programs in college populations, though small studies suggest herbs and spices can improve meal palatability and related dietary behaviors.
