If you’re dealing with osteoarthritis (OA) of the knees, here’s some good news: research published in the journal says that a diet rich in fruits and vegetables has been shown to help reduce inflammation and pain in your joints.
Read on to learn about how food can help your OA.
Food and OA
Inflammation produces free radicals, the cell-damaging molecules that are formed in response to toxins and natural bodily processes. The synovium (the cushion between knee joints) is as prone to free radical damage as the skin, eyes, or any other body tissue.
Antioxidants protect the body from free radicals. from the and Clinical Rheumatology has shown that certain antioxidants may help prevent arthritis, slow its progression, and relieve pain. Being at a healthy weight is a critical component to managing OA of the knees.
Avoiding extra body fat doesn’t just take weight off your knees. Body fat is metabolically active, so it’s capable of producing hormones and chemicals that actually increase levels of inflammation.

While absorbing sunlight before applying sunscreen is your best source of vitamin D, you can also enjoy these vitamin D-rich foods:

Beta carotene is another powerful antioxidant that helps destroy free radicals before they can cause excessive damage to joints. Beta carotene is easy to identify because it gives fruits and vegetables, such as carrots, their bright orange color. Other excellent sources include:
- cruciferous vegetables such as Brussels sprouts, collard greens, mustard greens, and chard
- greens such as romaine lettuce and spinach
- sweet potatoes
- winter squash
- peppermint leaves

Omega-3 fatty acids
The healthiest fats for people with OA, or other inflammatory disorders, are omega-3 fatty acids. While some foods increase levels of inflammation in the body, omega-3s actually work to decrease inflammation by suppressing the production of cytokines and enzymes that break down cartilage.
Foods with the highest amount of omega-3 fatty acids are:
- salmon, either wild, fresh or canned
- mackerel, but not king mackerel
- rainbow trout
- Pacific oysters
- omega-3-fortified eggs
- ground flax seed and flaxseed oil

Bioflavonoids such as quercetin and anthocyanidins are both forms of antioxidants. The anti-inflammatory effects of quercetin may be similar to those of nonsteroidal anti-inflammatory medications (NSAIDs) such as aspirin (Bayer) and ibuprofen (Advil, Midol). Good sources of quercetin include:
- red, yellow, and white onions
- cherry tomatoes
- black currants
- cocoa powder
- green tea
- apples with skin

Some spices have anti-inflammatory effects, too. Among the most promising are ginger and turmeric. Grate fresh ginger into stir fries, add it to salad dressings, sip ginger tea, and add to high-fiber, low-fat muffins.
Turmeric is a mustard-yellow spice from Asia that’s the main ingredient in yellow curry. A study cited in the journal has shown that curcumin may help osteoarthritis by suppressing inflammatory body chemicals. Curcumin is a major active component of turmeric.
