That’s why what you eat can help manage pain. So, is there a certain psoriatic arthritis diet you should follow?
While certain foods like fish high in omega-3 fatty acids can help lower inflammation, other options like processed foods or foods that contain sugar can cause flare-ups.
Rheumatologist Binita Sapkota, MD, explains how your diet can impact psoriatic arthritis, what foods to eat and avoid — and if following certain diets can be beneficial.
When it comes to psoriatic arthritis management, what you eat plays a key role.
You want to focus on eating anti-inflammatory foods, as they can help reduce a flare-up. And maintaining a healthy weight is important as well, as any extra weight puts more stress on your joints.
“Obesity is a known risk factor for causing psoriatic arthritis,” says Dr. Sapkota. “Obesity can increase trauma in the joints and in areas where tendons insert into the joint. Weight management is a very important component in the management of psoriatic arthritis.”
Here are some foods to eat when you have psoriatic arthritis:
Studies have shown that eating omega-3 fatty acids can help those with psoriatic arthritis decrease their joint tenderness and joint redness and how often they need to use over-the-counter pain relievers.

“Foods that are high in omega-3 fatty acids have been found to have antioxidant properties, as well as anti-inflammatory properties,” notes Dr. Sapkota. “Consuming omega-3 fatty acids is also good for your heart health and your general health.”
Foods that are high in omega-3 fatty acids include:
You also want to consider adding fruits and vegetables, as well as other foods, that are high in antioxidants to your diet. Antioxidants are known to help decrease the amount of oxidative stress that comes from chronic inflammation.
Foods that are high in antioxidants include:
Additionally, eating whole grains that are high in fiber can be helpful in managing your psoriatic arthritis. Research shows that for people with psoriatic arthritis, there’s a connection between weight, blood sugar and chronic inflammation.
Dr. Sapkota states that high-fiber whole grains are digested slowly, which helps reduce any blood sugar spikes.
Foods that are good sources of whole grains include:
“People with psoriatic arthritis have different types of gut bacteria compared to the general population,” explains Dr. Sapkota. “A high-fiber diet can promote healthy gut flora. And a high-fiber diet helps maintain a healthy weight, which is helpful for those with psoriatic arthritis.”
Are there certain foods that cause psoriatic arthritis flare-ups? Yes. Dr. Sapkota suggests avoiding the following foods:
“These types of foods are known to increase inflammation and they can also cause an increase in your weight, which is not good for psoriatic arthritis,” Dr. Sapkota adds.
It can be overwhelming to think about changing your eating habits.
Is there one recommended diet for psoriatic arthritis management? While certain diets can provide guidance on what foods to eat or avoid, Dr. Sapkota says it’s hard to find a one-size-fits-all solution when it comes to treating psoriatic arthritis.

“There’s no single diet that fits everyone with psoriatic arthritis,” she says. “I would recommend trying one type of diet and avoiding certain foods to find which one works best for you.”
For example, some people might be sensitive to gluten, so following a gluten-free diet may help with their symptoms. Other may have an intolerance to dairy and need to avoid products that contain dairy.
“It’s all an individual approach and you have to figure out which one helps you the best and follow that,” she emphasizes.
Overall, Dr. Sapkota doesn’t recommend the keto diet, which involves eating red meat. “Red meat is considered highly inflammatory.”
But in general, she’s a fan of the Mediterranean diet, which includes plenty of nuts, fruits and vegetables.
When it comes to managing your psoriatic arthritis through what you eat, Dr. Sapkota says her best advice is to avoid foods like red meat, sugar and processed foods that can cause inflammation and lead to a flare-up.
“Avoiding those foods tends to help everyone with psoriatic arthritis,” she says. “After that, you can try to identify certain triggers and eliminate those types of food from your diet.”
And don’t get too hung up on sticking to certain diets — whether it’s a vegetarian diet or the paleo diet. It’s best to keep it simple and focus on what you’re eating rather than the plan you’re following.

“Just try to include healthy food in your diet and avoid foods that you find that your symptoms are triggered by,” Dr. Sapkota encourages.
And when it comes to eating better, exercise like walking or swimming also plays a role in managing your psoriatic arthritis symptoms.
“Both diet and exercise are linked with obesity and weight,” she adds. “Not only does exercise help with strengthening your muscles, but it also decreases the stress in your joints and helps you reach a healthy weight.”
