16 Foods to Eat or Avoid for Psoriatic Arthritis

Inflammatory autoimmune condition like psoriatic arthritis is an ailment in which the immune system attacks the joints and causes symptoms like joint pain and stiffness.

There is no known cure for psoriatic arthritis. But adhering to a treatment plan and changing your lifestyle to include eating an anti-inflammatory diet and exercising will help reduce inflammation and ease your symptoms.

Regardless of your disease, maintaining a nutritious diet is a good idea. People with psoriatic disease select a wide range of meals that provide a variety of nutrients, eat frequently to combat the fatigue linked to the condition and watch portion sizes. Your weight can influence your ailment and how well your therapy works.

Mentioned are 16 foods that may benefit or harm people with psoriatic arthritis.

Foods to Eat for Psoriatic Arthritis

These are the foods to consume with Psoriatic Arthritis.

Whole Grains

Whole grains are rich in fiber and can support normal blood cholesterol levels. Examples include brown and wild rice, whole-wheat pasta, quinoa, barley, and bulgur wheat.

Psoriatic arthritis may make high blood cholesterol, one of the main risk factors for heart disease, even more likely. High blood lipids level like cholesterol exacerbate inflammation of the blood vessel wall.

Doctors advise women to aim for 25 grams of fiber daily, while men should aim for 38 g.


Anti-inflammatory Omega-3 fatty acids, abundant in salmon, can alleviate joint pain and swelling symptoms and help prevent heart disease, diabetes, and stroke.

To safeguard your heart health, doctors advise eating salmon and other fatty fish, such as albacore tuna, mackerel, herring, and lake trout, at least twice a week.

Cherries and Berries

Anthocyanins are phytonutrients found in cherries and berries, especially dark types like blueberries, blackberries, and raspberries, which reduce inflammation. Eating cherries (sweet and sour) may help reduce inflammation in the body. Vitamin C-rich foods like strawberries and raspberries can help reduce your chances of developing high cholesterol and blood pressure.


Flavonoid in apples, quercetin, has been shown to alter inflammatory reactions by preventing the generation of prostaglandins, which are inflammatory substances that induce pain. Pectin, a type of soluble fiber abundant in apples, fills you up and prevents snacking, which is significant because reducing inflammation in the body is associated with weight reduction.


It is another nutritional powerhouse to include in a psoriatic arthritis diet that reduces inflammation. Kale has a variety of flavonoids with a range of antioxidant and anti-inflammatory benefits in addition to being high in fiber and vitamins A, C, and K.


The phytochemical capsaicin in hot and sweet bell peppers has a potent anti-inflammatory effect. Substance P, the chemical in the body that causes inflammation and pain signals from the central nervous system, is decreased by capsaicin.

This numbing phytochemical causes the body to release endorphins, which are endorphins' equivalent of opiates. Salicylates are chemical substances similar to aspirin and are found in red peppers.

Olive oil

Another essential component of an anti-inflammatory diet is extra-virgin olive oil. Monounsaturated fat, antioxidants, and oleocanthal—a substance that has anti-inflammatory and pain-relieving properties similar to ibuprofen—are all present in olive oil. C-reactive protein and other inflammatory markers can be decreased by oleic acid.

Add two to three teaspoons of extra-virgin olive oil to your daily salad dressings and snacks.


Although you may only think of garlic as a flavoring agent, it is also a vegetable with powerful anti-inflammatory phytonutrients.

Strong-flavored vegetables, such as garlic, contain these phytonutrients. Use fresh garlic only, as preservatives frequently added to powdered or bottled garlic may lessen some of its anti-inflammatory effects.


Turmeric is an anti-inflammatory food. The compound curcumin in this spice has long been utilized in Ayurvedic medicine as an antioxidant and digestive aid. Researchers found that turmeric may help manage oxidative and inflammatory disorders, including arthritis and pain.

Turmeric is used in sauces, cheese, chips, and even tea.


Nuts contain polyunsaturated and monounsaturated fats, which lower cholesterol and prevent heart disease, a condition for which persons with psoriatic arthritis are at high risk. Moreover, nuts are a great source of magnesium and other nutrients that might help reduce inflammation.

Alpha linoleic acid, an omega-3 fatty acid that reduces inflammation, is abundant in walnuts. Almonds and cashews are two nuts that are rich in magnesium.


Yogurt and other fermented foods include probiotics, which help the gut grow healthy bacteria. Probiotics in the diet may help reduce disease formation in the body.

Black and Green Tea

The antioxidants in green and black tea may be more effective than those in many fruits and vegetables. In addition, tea contains potent anti-inflammatory substances called polyphenols that reduce the generation of nitric oxide, a factor in inflammation.

The most well-known polyphenol is epigallocatechin-3 gallate (EGCG), a substance found to lower cyclooxygenase-2 (COX-2), a significant inflammatory enzyme in arthritis, from its active state.

Foods to Avoid with Psoriatic Arthritis

While picking the correct items to include in an anti-inflammatory diet is crucial, avoiding some foods is just as critical. These are the foods to avoid with Psoriatic Arthritis.

Processed Meats

Processed foods and fatty red meats are at the top. Prime rib, bacon, sausage, bologna, and hot dogs contribute to the body's inflammatory process and weight gain. While weight increase encourages inflammation and even lessens the effectiveness of some medications for psoriatic arthritis, this can spiral out of control.

Due to pain and inflammation, many patients with psoriatic arthritis may be overweight and less likely to exercise, which increases the risk of heart disease.

Sugary Drinks and Foods

Inflammation is caused by refined sugars in soda, juice, chocolate, sweets, and other baked products. Eating more sugar makes you gain weight and additional strain on your joints, and raises your risk for heart disease and stroke.

Look for sources of sugar on food labels, such as fructose or sucrose, by reading the labels. Instead, eat some fresh fruit as a snack to satiate your sweet taste.


Milk contains a lot of calcium, which is essential for strong bones. Yet, some people lack the enzyme necessary to digest milk products. Milk may contain hormones and medicines that can alter your body's immunological response, even if you can tolerate them. As a result, drinking dairy may cause you to have gastrointestinal issues.

Avoid using dairy products and replace them with calcium-rich foods like oranges, spinach, and almonds.


Individuals with psoriatic arthritis may experience an aggravation of symptoms from eating certain nightshade foods, such as eggplant, potatoes, and tomatoes. Solanine frequently included in certain foods, maybe the culprit.

If you discover that nightshade vegetables are problematic, avoid them in favor of kale and other leafy greens, which have anti-inflammatory properties without aggravating your symptoms.


Diets are highly customizable. A diet plan that is perfect for one person might not suit the other person. Weight loss and a balanced diet help reduce the effects of psoriatic arthritis, regardless of the foods you consume or avoid.
