 Diet plays a central role in the regulation of chronic inflammation. However, until the investigators developed the dietary inflammatory index DII there had been no scientifically valid way to relate what individuals eat to the capacity of foods consumed to modulate inflammation. The DII provides a tool that will form the basis of a counselinginstructional system aimed at helping patients and their providers to control chronic, systemic inflammation by improving the diet with specific, actionable dietary recommendations, counseling, and expert instruction. The goal of this study is to test the applicability of a DII mobile tool and associated counseling measures in clinical practice.
