New Data Clarify Relationship Between Diet And Disease Activity
Intake of monounsaturated fatty acids and cholesterol influence disease activity in RA and OA respectively
In the TOMORROW study, daily intake of monounsaturated fatty acids as a component of the Mediterranean diet has been shown to be an independent predictor of remission in patients with RA; monounsaturated fatty acids might therefore be suppressing disease activity1
In another study, using an experimental animal model of OA, accumulation of LDL-cholesterol resulted in an increase in synovial thickening and ectopic bone formation, with excessive cholesterol levels shifting the balance towards increased cartilage damage2
Researchers have been exploring the link between diet and different types of arthritis since the 1930's.3 While the relationship between diet and arthritis is certainly complex, these two studies have highlighted the importance of addressing dietary intake of monounsaturated fatty acids and cholesterol when treating patients with RA and OA respectively.
Dietary intake of monounsaturated fatty acids independently predicts remission in RA Using the RA disease activity score calculator DAS28-ESR to categorise patients as having active disease or being in remission, dietary intake of monounsaturated fatty acids was shown to be an independent predictor of remission in patients with RA (Odds: 0.51; 95% CI = 0.25
