Arthritis sufferers warned to avoid eating two foods that ‘trigger pain’

47views

People with arthritis are being warned about two common fruits—apples and tomatoes—that could potentially worsen their symptoms.

Arthritis, a condition that causes joint pain, swelling, inflammation, and mobility issues, has no cure, but its symptoms can often be managed through lifestyle changes, including diet. While certain foods can help reduce inflammation, others may act as “pain triggers,” exacerbating the condition.

The NHS lists common arthritis symptoms as joint pain, tenderness, stiffness, inflammation, restricted movement, warm red skin over affected joints, and muscle weakness.

Diet plays a significant role in managing these symptoms, and the Physicians Committee has identified apples and tomatoes as potential triggers for arthritis pain. Both fruits contain solanine, a natural compound found in nightshade plants, which some studies suggest may worsen inflammation and joint pain in people with arthritis.

A 2013 study published in the *Arab Journal of Nuclear Sciences and Applications* explored the link between solanine and arthritis. The research, conducted on postmenopausal rats, found that solanine could exacerbate joint pain and tissue damage in those with arthritis.

The study recommended that individuals with arthritis, particularly older adults and postmenopausal women, avoid nightshade plants like tomatoes and potatoes to alleviate symptoms.

However, not all health organizations agree with this recommendation. The Arthritis Society Canada, for example, advises people to monitor how their bodies react to solanine-rich foods rather than eliminating them entirely. This approach recognizes that dietary triggers can vary from person to person.

In addition to dietary considerations, recent research has highlighted a potential new treatment for autoimmune forms of arthritis, such as rheumatoid arthritis.

A drug called Canagliflozin, commonly used to manage blood sugar in type 2 diabetes, has shown promise in influencing T-cells, which play a role in autoimmune diseases. By regulating these cells, the drug could provide relief for over 400,000 people in the UK living with rheumatoid arthritis and 50,000 with lupus.

For those managing arthritis, paying attention to diet and exploring new treatments can be key to reducing symptoms and improving quality of life.

While apples and tomatoes may be problematic for some, individual responses to food can vary, so it’s important to consult with a healthcare professional before making significant dietary changes.
