Psoriatic arthritis affects millions of people worldwide, causing inflammation and pain in the joints and skin. While there is no cure for psoriatic arthritis, proper nutrition can help manage symptoms and improve overall health.

This article will explore the role of nutrition in managing psoriatic arthritis, including which foods to eat and which to avoid.

What is Psoriatic Arthritis?

Psoriatic arthritis is a type of arthritis that affects people with psoriasis, a chronic skin condition. It often causes joint pain, stiffness, and swelling, as well as skin lesions.

The exact cause of psoriatic arthritis is unknown, but it is believed to be an autoimmune condition that occurs when the body’s immune system mistakenly attacks healthy cells and tissues.

How Nutrition Impacts Psoriatic Arthritis

Nutrition plays an important role in managing psoriatic arthritis, as certain foods can help reduce inflammation and pain in the joints and skin while others can exacerbate symptoms.

For example, a diet high in fruits, vegetables, whole grains, and lean protein can help reduce inflammation and improve overall health, while a diet high in processed and fried foods, saturated and trans fats, and sugar can increase inflammation and worsen symptoms.

Foods to Eat

When managing psoriatic arthritis with nutrition, it is important to focus on whole, nutrient-dense foods that contain anti-inflammatory compounds. Some examples of foods to eat include:.

Fruits and vegetables: These are rich in antioxidants and other anti-inflammatory compounds that can help reduce inflammation in the body. Some good options include leafy greens, berries, citrus fruits, and cruciferous vegetables like broccoli and cauliflower.
Whole grains: These provide fiber and other nutrients that can help reduce inflammation and improve gut health. Examples include quinoa, brown rice, and whole wheat bread.
Lean protein: This is important for building and maintaining muscle, and can also help reduce inflammation. Good sources of lean protein include chicken, turkey, fish, and legumes.
Healthy fats: Certain fats, such as omega-3 fatty acids, have been shown to have anti-inflammatory effects. Good sources of healthy fats include fatty fish like salmon, nuts and seeds, and avocado.
Probiotic foods: These contain beneficial bacteria that can help improve gut health and reduce inflammation. Good sources of probiotics include yogurt, kefir, sauerkraut, and kimchi.

Foods to Avoid

When managing psoriatic arthritis, it is important to avoid foods that can worsen inflammation and symptoms. Some examples include:.

Processed and fried foods: These are often high in unhealthy fats and sugar, which can increase inflammation. Examples include fast food, chips, and pastries.
Saturated and trans fats: These are found in red meat, butter, and other dairy products, and can increase inflammation in the body. It is important to limit these foods and choose lean protein and healthy fats instead.
Sugar and refined carbohydrates: These can cause spikes in blood sugar and increase inflammation. Examples include candy, soda, and white bread.
Alcohol: This can worsen inflammation and may interact with certain medications. It is important to limit alcohol consumption and talk to your doctor about whether it is safe for you.
Nightshade vegetables: Some people with psoriatic arthritis have reported that nightshade vegetables like tomatoes, peppers, and eggplant can worsen symptoms. While there is limited scientific evidence to support this, it may be worth avoiding these foods if you notice that they worsen your symptoms.

Supplements for Psoriatic Arthritis

In addition to eating a healthy diet, certain supplements may also help manage psoriatic arthritis. Some options to discuss with your doctor include:.

Fish oil: This supplement contains omega-3 fatty acids, which can help reduce inflammation in the body.
Curcumin: This is a compound found in turmeric that has been shown to have anti-inflammatory effects.
Probiotics: These supplements contain beneficial bacteria that can help improve gut health and reduce inflammation.
Vitamin D: This vitamin plays a role in immune function and may help reduce inflammation in the body. However, it is important to talk to your doctor about whether you need a supplement, as too much vitamin D can be harmful.

Conclusion

While there is no cure for psoriatic arthritis, proper nutrition can help manage symptoms and improve overall health.

Eating a diet rich in fruits, vegetables, whole grains, and lean protein can help reduce inflammation and pain in the joints and skin, while avoiding processed and fried foods, saturated and trans fats, and sugar can worsen symptoms. In addition, certain supplements may also help manage psoriatic arthritis, but it is important to talk to your doctor before starting any new supplements.
