According to several studies, red and processed meat cause inflammation, which may aggravate arthritis symptoms.
Diets high in processed and red meats, for example, have high levels of inflammatory markers such as interleukin-6 (IL-6), C-reactive protein (CRP), and homocysteine.
The above-mentioned research of 217 patients with RA discovered that red meat frequently exacerbated RA symptoms. In addition, research of 25,630 participants found that eating a lot of red meat may be a risk factor for inflammatory arthritis.
Plant-based diets that omit red meat, on the other hand, have been found to alleviate arthritic symptoms.
