How Does Diet Affect Osteoarthritis
At Peak Health Physiotherapy, we see lots of people suffering from osteoarthritis.
One of the key things we strive to educate our clients about is the significant impact that diet can have on your osteoarthritis.
There’s more to your recovery than just medication and rehab – what you eat, the state of your gut health, and even the supplements you choose play a vital role.
Before we dive into the specifics of nutrition, it’s important to address a critical factor that often goes hand in hand with osteoarthritis: obesity.
Obesity and Osteoarthritis
Obesity is not just a number on the scale – it has real implications for your joint health. Excess weight not only increases the mechanical load on your joints but also triggers the release of pro-inflammatory substances called adipokines, which can worsen osteoarthritis symptoms even in joints that aren’t weight-bearing
Studies have shown that:
- A reduction in BMI by as little as two units can reduce the risk of developing osteoarthritis by up to 54% over ten years.
- Increasing BMI over time is linked to a faster decline in cartilage volume, impairing joint function.
- Even modest weight loss (around 5% of body weight) can noticeably reduce pain and inflammation, with greater improvements as weight loss increases.
At Peak Health Physiotherapy, we combine physiotherapy with tailored dietary advice to help our clients achieve a healthier weight, relieve joint pressure, and improve overall function.
Why Your Diet Matters
Food can play a pivotal role in reducing inflammation and easing joint pain.
Research shows that incorporating nutrient-dense foods into your daily routine can help your joints feel more comfortable and support better mobility.
Here’s a closer look at some of the dietary elements we often recommend:
Fruits and Berries
- Blueberries and Strawberries:
Even a small portion of freeze-dried berries is linked to reduced pain and improved mobility. Packed with antioxidants, they help combat oxidative stress—a known contributor to joint inflammation. - Pomegranate Juice:
A daily glass may help reduce joint stiffness and support smoother movement. Rich in polyphenols, pomegranate juice can help neutralise inflammatory markers and protect your cartilage. - Passion Fruit Extract:
Early research suggests that passion fruit peel extract might offer pain relief and improved joint function, providing an alternative way to manage discomfort.
Protein, Dairy, and Fish – The Building Blocks for Strong Joints
- Milk and Full-Fat Dairy:
Regular milk drinkers may have a lower risk of developing knee osteoarthritis. Full-fat dairy is a good source of calcium, vitamin D, and other essential nutrients that support joint health. - Soy and Milk Proteins:
Whether you’re a fan of dairy or prefer plant-based options, both soy and milk proteins provide the building blocks your joints need for repair and maintenance. - Meat in Moderation:
While moderate red meat consumption has been linked in some studies to a lower risk of joint issues, it’s best to limit processed meats that can trigger inflammation. - Fish and Omega-3 Fatty Acids:
Fatty fish such as salmon, mackerel, and sardines are excellent sources of omega-3s, renowned for their anti-inflammatory properties. Regular consumption of fish, or the use of omega-3 supplements if needed, can help reduce joint inflammation and improve mobility.
Vitamins and Minerals
Vitamins are essential for maintaining joint health and reducing inflammation:
- Vitamin C: Adequate intake is linked to a reduced risk of osteoarthritis progression and aids in cartilage repair.
- Vitamin E: This antioxidant can help alleviate symptoms by reducing oxidative stress.
- Vitamin K: Low levels have been associated with a higher risk of joint space narrowing and other osteoarthritis-related changes.
- Vitamin D: Crucial for bone health, low levels are common in people with osteoarthritis.
- Magnesium: Emerging evidence suggests that proper magnesium intake supports joint health and may help lower pain levels.
The Gut-Joint Connection
It might seem surprising, but your gut health has a lot to do with the condition of your joints.
Our gut is home to trillions of bacteria that not only help digest food but also support our immune system.
Some bacteria produce substances that can either calm or increase inflammation—and chronic inflammation is a major factor in osteoarthritis.
Feed Your Gut Right
- Fibre-Rich Foods:
Whole grains, fruits, vegetables, legumes, and nuts are excellent sources of fibre. These foods keep your gut bacteria happy, encouraging them to produce anti-inflammatory compounds that benefit your joints. - Phytonutrients:
Naturally occurring compounds in plant foods help reduce overall inflammation and support the healing process.
Overall Dietary Patterns
It’s not just about individual foods—it’s the overall pattern of what you eat:
- The Standard Western Diet:
Often high in red and processed meats, sugars, and refined grains, this diet can lead to increased inflammation and worsen joint pain. - A Healthier Alternative:
Adopting a balanced eating plan—such as the Mediterranean diet—rich in fruits, vegetables, whole grains, lean proteins, and healthy fats (like olive oil) can be a game changer. This approach not only supports joint health but also helps maintain a healthy weight and boost your mood.
Supplements for Osteoarthritis
In addition to dietary adjustments, certain supplements may further support joint health.
Research has investigated a range of supplements, with varying results. Some that have shown promise include:
- Glucosamine and Chondroitin:
Clinical studies suggest that these supplements (commonly taken as 1500mg of glucosamine and 800–1200mg of chondroitin daily) may offer modest improvements in joint pain and function for some individuals. - Collagen Hydrolysate:
Supplementing with around 10g per day has been linked to improvements in joint comfort, reduced pain, and enhanced mobility in several trials. - Boswellia Serrata Extract:
Used at doses around 338mg daily, Boswellia extract has demonstrated reductions in pain and stiffness, likely due to its anti-inflammatory properties. - Omega-3 Fatty Acids:
As noted earlier, omega-3s from fish oil can reduce joint inflammation and support overall joint function. - Probiotics:
Some strains of probiotics may help modulate the gut microbiome and reduce systemic inflammation, although further research is needed to confirm their benefits specifically for osteoarthritis.
Remember, supplements should complement, not replace, a balanced diet and physiotherapy programme. Always consult a healthcare professional before adding new supplements to your routine.
