Arthritis affects about 10 million people in the UK, according to the NHS.
Symptoms include joint pain, stiffness, muscle wasting and having warm, red skin over affected joints.
Regular exercise and watching your weight could help to prevent arthritis.
Eating nuts could also help to relieve joint pain, said Aetna International’s Director of Population Health, Dr Sneh Khemka.
“Arthritis is a tricky condition – it is difficult to predict the onset and severity of disease,” said Khemka.
“There are over 100 forms of arthritis; some are genetic, for example rheumatoid arthritis; whereas others are related to age, such as osteoarthritis.
“We can tackle arthritis by raising awareness of the symptoms and encouraging the adoption of healthy habits to help tackle these early and prevent disability.
“Nuts, including peanuts, walnuts, pistachio nuts all contain immune boosting vitamin and minerals and are beneficial to weight loss.”
Some nuts and seeds are a good source of healthy fats, protein and antioxidants.
Peanuts have the most protein, and they could help to lower heart disease risk, according to the Arthritis Foundation.
Walnuts are packed full of omega-3, and may reduce inflammation linked to arthritis.
Almonds, flaxseed and chia seeds could also help to relieve arthritis symptoms, the foundation said.
Eating a healthy, balanced diet could lower your risk of flare-ups, the NHS said.
If you’re overweight, losing weight can help you to copy with arthritis-related joint pain, it added.
Keeping active can help to reduce and prevent pain. It could also reduce stiffness, increase muscle strength and boost your range of movement.
Some painkillers and non-steroidal anti-inflammatory drugs could be used to treat arthritis.
