People with knee arthritis in their 40s to 80s tend to eat foods that slightly spark inflammation, like processed meats and sugary snacks—but when you adjust for how much they eat overall, their diet is a bit less inflammatory than it first looks.

Assessment Explanation
The claim reports descriptive statistics (means and standard deviations) from a baseline assessment in a specific population. These values are observational and do not imply causation or intervention effects. The use of 'indicating' and 'suggesting' appropriately reflects probabilistic interpretation of population-level data. No overstatement is present, as the claim does not imply that the scores cause or prevent outcomes—only that they were measured. The values are consistent with published literature on DII in osteoarthritis cohorts.
More Accurate Statement
“Among adults aged 45–85 with knee osteoarthritis, the mean baseline dietary inflammatory index (DII) score was 0.58 (SD = 1.49), suggesting a pro-inflammatory dietary pattern, while the energy-adjusted DII (E-DII) score was -0.31 (SD = 1.41), indicating a modestly lower inflammatory potential after adjusting for total energy intake.”

The study measured how inflammatory people's diets were before starting any treatment, and the numbers it found were exactly the same as the ones in the claim — so the claim is backed up by the study.
