Dietary choices are particularly important for controlling weight and reducing the burden on the joints

It is widely believed that what we eat plays a significant role in the onset of conditions such as arthritis. The old adage about being what one eats has led many to draw direct connections between their plate and their joint pain.

However, this assumption may be more fiction than fact.


Contemporary medical understanding indicates that dietary choices have a rather restricted influence on both the prevention and treatment of the most prevalent forms of arthritis.

While maintaining a nutritious diet certainly supports overall well-being, the evidence suggests that food plays a limited part in arthritis management for the majority of sufferers.

That said, some dietitians warn that dietary factors may still exacerbate symptoms.

Reema Kanda, a dietitian at Hoag Orthopaedic Institute, told GB News: "Overly processed foods are going to be some of the biggest triggers for those with arthritis."

She explained that inflammation represents the primary consequence of consuming such foods.

Crucially, the expert noted that isolated instances of poor dietary choices are not the culprit.

"Regular consumption of highly processed foods will cause the effects to occur. The pattern is more harmful than any one individual food," Kanda stated.

This suggests that those concerned about their joint health ought to focus on their overall eating habits rather than fretting over occasional indulgences.

When considering arthritis management, dietary choices become particularly relevant for controlling weight and reducing the burden on the joints.

Kanda stressed this connection, noting that what we eat plays a substantial role in managing body mass and thereby alleviating physical strain on our skeletal system.

Yet rheumatoid arthritis presents an altogether different challenge.

"However, when we talk about Rheumatoid arthritis, we begin talking about autoimmune complications which have their own set of hurdles," the dietitian explained.

For those with this autoimmune variant, inflammation poses a considerably greater threat, and dietary choices can produce more pronounced effects on symptoms and overall condition.

Kanda expressed surprise at tomatoes appearing on lists of foods to avoid for arthritis sufferers.

"I am actually pretty shocked to hear that tomatoes are showing up on people's avoid list," she remarked.

For those who do experience sensitivities, dairy products tend to be among the more straightforward items to identify and remove from one's diet.

Nevertheless, the dietician urged caution against hasty decisions regarding food elimination.

"I encourage people not to jump to conclusions, though, and cut out food so quickly. Definitely begin to track potential symptoms, but always then check in with a medical professional just to make sure you are on the right track," Kanda advised.
