Researchers from the University of South Carolina Arnold School of Public Health’s departments of Health Promotion, Education, and Behavior, Epidemiology and Biostatistics, and Exercise Science as well as the Cancer Prevention and Control Program — all at the University of South Carolina — have completed a study examining the impact of a 12-month inflammation management intervention on the Dietary Inflammatory Index (DII®), inflammation and lipids. The study was led by associate professor Dr. Brie Turner-McGrievy, funded by a grant from the National Institute of Diabetes and Digestive Disorders and Kidney Diseases to Dr. James Hébert, Dr. Michael Wirth, and Dr. Nitin Shivappa, and published in Clinical Nutrition ESPEN.
With this study, the authors aimed to assess the feasibility (ability to recruit participants and develop the 12-month intervention), acceptability (retention of participants in the intervention), and impact on systemic inflammation and DII scores over a 12-month DII-based intervention.
The researchers recruited adults to participate in a self-selection trial (intervention: n = 61, in-person classes; control: n = 34, newsletters). Classes included participatory cooking and dietary recommendations focused on consuming a plant-based diet rich in anti-inflammatory foods (spices, vegetables, etc.). They analyzed changes in markers of inflammation, lipids, and DII using general linear models with repeated measurements.Friday Letter Submission
