Protein Found In Meat Linked To Increased Risk Of Arthritis

A recent study published in the Journal of Clinical Investigation has linked the protein tryptophan, found primarily in meat and dairy products, to an increased risk of developing arthritis. When tryptophan is broken down by gut bacteria, it produces a compound that triggers an inflammatory response, leading to rheumatoid arthritis or spondyloarthritis. The study found that a diet rich in plant-based fibers and lean meats, such as the Mediterranean diet, could help shift the microbiome towards a healthier state and reduce inflammation associated with tryptophan breakdown.

While the study is groundbreaking in highlighting the inflammatory effects of tryptophan breakdown, previous research has also linked meat consumption to arthritis. Conversely, studies have shown that plant-based diets can alleviate the symptoms of rheumatoid arthritis, and lower disease risk in general. More research is needed to further explore the connection between diet and arthritis, with an emphasis on how to balance tryptophan breakdown towards anti-inflammatory pathways to reduce the risk of arthritis development.
