Arthritis symptoms include joint pain and inflammation, according to the NHS.
Restricted movement and having warm, red skin over the affected joint could also be a sign of the condition.
There’s currently no cure for arthritis, but there are ways to help reduce symptoms.
Eating more raspberries could help to slow down the condition’s progress, according to a nutritionist.
“Raspberries have amazing anti-inflammatory properties that may alleviate symptoms of arthritis,” said nutritionist Dr Josh Axe.
“That’s why raspberries make a great addition to any arthritis diet plan.”
Raspberries contain polyphenols that have anti-inflammatory effects, studies have claimed.
Anthocyanins and ellagitannins could both provide relief to painful joints, said US scientists.
Raspberries could also help to improve your heart’s health.
Its anti-inflammatories boost blood flow around the body and to vital organs.
You could also lower your risk of some cancers by eating more raspberries, studies have claimed.
The fruit contains an acid that could have anti-tumour and chemopreventative properties.
Arthritis symptoms could also be reduced by taking painkillers, or non-steroidal anti-inflammatory drugs, the NHS said.
Eating a healthy, balanced diet could ease some of the joint pain caused by the condition.
Regular exercise can reduce stiffness and increase muscle strength.
If you’re overweight, losing a few pounds could really help you to cope with arthritis, the NHS added.
