Abstract
A systemic, inflammatory illness such as rheumatoid arthritis (RA) causes progressive cartilage and bone degradation in addition to joint involvement. Factors related to genetics and environment determine susceptibility to RA. In recent years, an increasing body of research has illuminated the pivotal role of diet and lifestyle in influencing the risk and progression of illnesses. Some nutrients, like polyunsaturated fatty acids, can combat inflammation. They also act as antioxidants, thus protecting against the onset of RA. Conversely, substances like salt and red meat have adverse effects, promoting the development and progression of RA through indirect mechanisms that impact gut microbiota and body composition. As we look ahead, potential supplementary therapies alongside the existing RA treatment regimen may manifest as specific dietary patterns and supplements. Promising candidates include the Mediterranean Diet (MD), vitamin D, and probiotics, which could potentially confer protective benefits. A poor level of education and low socioeconomic status, as well as smoking, an unhealthy diet, and obesity, have all been linked to an increased risk of RA in large epidemiological studies. Additionally, several lifestyle choices affect how well RA responds to antirheumatic medications. A worse treatment outcome is linked, among other things, to smoking, obesity, and insufficient physical activity. Therefore, RA sufferers must be urged to live a healthy lifestyle and eat well.
