Rheumatoid arthritis (RA) is an autoimmune condition that can be affected by certain dietary choices. The foods that are most likely to aggravate RA symptoms include those belonging to the nightshade family, which is where tomatoes and potatoes fall. These foods contain alkaloids, which some studies suggest may exacerbate inflammation and pain in those with rheumatoid arthritis.

While the other food groups listed can have varying effects on individuals, they are generally not associated with aggravating RA. Berries and nuts, for instance, contain antioxidants and healthy fats that can support reducing inflammation. Citrus fruits and dairy, while sometimes contentious in their potential impact on inflammation, do not have as strong a correlation with RA symptoms as nightshades do. Whole grains and legumes are known to provide beneficial nutrients and fiber that may support overall health rather than provoke joint issues.

Thus, the inclusion of tomatoes and potatoes in the diet is particularly noteworthy for individuals with rheumatoid arthritis and may offer insight into dietary management of the condition.
