Effect of Anti-inflammatory (ITIS) Diet in Rheumatoid Arthritis

Effect of Anti-inflammatory (ITIS) Diet in Rheumatoid Arthritis

to study the effect of anti-inflammatory diet on clinical and biological outcomes in rheumatoid arthritis

The investigators would like to evaluate how inflammation occurs in the joints of subjects with arthritis, and identify molecules and bacteria that can predict whether a rheumatic subject will flare. Blood, urine and stool will be evaluated in the laboratory and compared to their own samples after changes in diet. This is an exploratory study, which is meant to gather preliminary data about the quick effects of changes in diet and treatment on molecules in blood/urine and bacteria in stools. These studies can provide clues to the cause of disease and might ultimately lead to new therapies.

Inclusion Criteria:

• patients diagnosed of rheumatoid arthritis
• without changes in treatment in the last 3 months

Exclusion Criteria:

• food allergies
• pregnancy
