The Claim

Among adults with rheumatoid arthritis, greater improvements in the energy-adjusted dietary inflammatory index (e-DII) are associated with significantly higher intakes of omega-3 fatty acids, dietary fiber, vitamin A, vitamin E, folic acid, and beta-carotene, and these nutrient changes do not correlate with statistically significant improvements in patient-reported pain, physical function, or quality of life.

In plain English

In adults with rheumatoid arthritis, diets that reduce inflammation based on nutrient content are linked to higher intake of omega-3 fatty acids, fiber, and certain vitamins, but these dietary changes are not linked to measurable improvements in pain, physical function, or quality of life.

See the scientific wording

Among adults with rheumatoid arthritis, greater improvements in the energy-adjusted dietary inflammatory index (e-DII) are associated with significantly higher intakes of omega-3 fatty acids, dietary fiber, vitamin A, vitamin E, folic acid, and beta-carotene, but these nutrient changes do not correlate with statistically significant improvements in patient-reported pain, physical function, or quality of life.

Why this might work

When people eat more omega-3 fats, fiber, and antioxidants like vitamins A and E, their cell membranes change to produce fewer inflammatory signals, their gut lining becomes tighter to block harmful substances from entering the bloodstream, and their body neutralizes damaging molecules that trigger inflammation. This lowers overall inflammation in the body, but it does not reduce pain, improve movement, or boost quality of life.

  1. Study: Comparison of mediterranean and healthy eating guideline interventions on the dietary inflammatory index in rheumatoid arthritis: results from a dietary randomised controlled intervention trial

    People with rheumatoid arthritis who ate more healthy foods like fish, vegetables, and whole grains had less inflammation in their diet, but they didn’t feel less pain or move better afterward — just like the claim says.
