Interpretive Summary:

Technical Abstract: Higher consumption of whole grain foods is associated with reduced risk of cardiovascular disease, diabetes, and obesity in observational studies; yet, in intervention studies, the effect of whole grains on intermediate markers of risk are mixed. This may be due to the variability in study design, differences in composition of different grains, degree of processing, and the definition of the whole grain intervention. Therefore, the aim of this project was to use evidence mapping to capture and summarize the methodological differences in whole grain intervention studies. We conducted a reproducible search in OVID Medline using a broad list of whole grain keywords to identify potentially relevant intervention studies. The search extended from inception of the Medline database (1946) to November 2015 and was restricted to human interventions published in English. After a two-step screening process, which included abstract and then full text screening, we identified 170 relevant publications which described a total of 180 whole grain interventions. Over half (57%, n=102) were acute interventions, lasting
