Sleepwalking into arthritis isn’t inevitable. And some changes can show up faster than most people expect.

In this episode, Dr Karan Rajan speaks with Professor Tamiko Katsumoto about why arthritis rates are rising, the differences between rheumatoid arthritis and osteoarthritis, and what the best evidence says about reducing joint inflammation, including a lifestyle medicine intervention where benefits were seen as early as 8 weeks (with the primary endpoint at 16 weeks).

This isn’t about “miracle cures.” It’s about stacking the odds in your favour: Diet quality, fibre, fermented foods, weight and metabolic health, sleep, stress, movement. And how these interact with inflammation, the gut, and joint symptoms.

In this episode, we cover:

∙ RA vs OA: Classic symptom patterns and why they’re treated differently

∙ Why treatments for osteoarthritis can feel limited (and why lifestyle is still worth discussing)

∙ “Food as medicine” and why joints are a symptom you can actually feel change

∙ The “Plants for Joints” study: What changed at 8 weeks and what the 16-week endpoint showed

∙ The gut-joint axis: Gut barrier, microbial diversity, and immune regulation

∙ Why some patients flare on ultra high meat / fibre-free approaches (and what to do instead)

∙ Practical “build my plate” guidance for joint and inflammation support
