Scientists have proven that smoking and coffee consumption directly increase the risk of various types of arthritis. The research was published in the journal nutrients.
Osteoarthritis and rheumatoid arthritis cause the cartilage in joints and bones to deteriorate. They are the reason why more than 500 million people have pain and difficulty walking.
In this study, researchers tested whether there was a cause-and-effect relationship between various lifestyle habits and arthritis risk. To do this, they used a Mendelian randomization method that assessed the existence of an association between, for example, mutations associated with a love of coffee and mutations responsible for arthritis risk. This approach allows us to exclude environmental influences and focus on the existence of a direct biological link between the disease and coffee consumption.
In the study, the presence of arthritis was evaluated using MRI. Scientists have found a cause-effect relationship between coffee drinking, smoking, and an increased risk of osteoarthritis and rheumatoid arthritis.
The quality of the included studies was rated as high and the risk of bias as low, supporting the strength of the data and the results of the new analysis. The results suggest that people prone to osteoarthritis and those already diagnosed should consider reducing their smoking and coffee consumption.
