Diet for Psoriasis and Psoriatic Arthritis

Diet for Psoriasis

Diet plays an important role in the treatment of Psoriasis. Certain food items such as red meat, alcohol, refined carbs, and simple sugars may exacerbate the condition.

On the other hand, a diet high in fiber, low in saturated fats, and high in vitamin D, vitamin B12, and selenium may improve the condition [Ref].


Psoriasis is an autoimmune disease. It is often seen as dry, and itchy, with red thick skin accompanied by silvery scales.

Your treating doctor may be recommending you the medications and ointment but it’s also a fact that diet plays a major role in the relief. Yes, what you put in your tummy plays a major role in psoriasis.

Does going gluten-free makes your psoriasis better?

Gluten is the general name for the protein found in wheat, rye, and barley. It is found in many foods including bread, soups, pasta, etc. To many people’s surprise, going gluten-free doesn’t reduce the severity.

There is one exception if you are suffering from “celiac disease” where the body mounts an inflammatory reaction to gluten, then a gluten-free diet can help in reducing severity.

Does losing weight improve psoriasis?

Does taking dietary supplements help your psoriasis?

Taking supplements may seem like a great idea. Larger studies have failed to show any evidence that shows help in psoriasis.

Fish oil and vitamin D may help improve your condition. In fact, vitamin D derivatives are used as topical medicines for the treatment of psoriasis.

The truth of Yogurt and Psoriasis:

The simple answer is yes, yogurt helps with psoriasis. Dairy products are considered a common food allergen due to the lactose and casein content of milk and dairy products.

These components of milk require extra effort to be properly digested, and psoriasis is an autoimmune disease associated with impaired gut health. So, people with psoriasis have trouble processing it and undigested lactose and casein which are caused by an impaired immune system perceived, making the symptoms worse.
