Eating the right food choices is often the first step in preventing and mediating many illnesses. After all, what we eat has a definite effect on our medical conditions. The same situation applies to psoriasis, with many foods triggering its flare-up. If so, most patients are looking for suggestions regarding the best diet for psoriasis prevention. Additionally, knowing the foods that trigger psoriasis can help prevent the severity of the psoriasis symptoms, reducing discomfort, and helping manage the condition. Here, the article will discuss the foods that must be prevented when suffering from psoriasis, including:

  • Dairy products and red meat
  • Gluten
  • Processed foods
  • Nightshades
  • Alcohol intake
  • What foods can you consume in psoriasis?
  • Fatty fish
  • Heart-healthy oils
  • Nutritional supplements

Dairy products and red meat

Eggs, dairy products, and red meat are rich in polyunsaturated fatty acids, including arachidonic acid. Research proves that the by-products of this acid may result in the creation of psoriatic lesions. If so, people who have psoriasis must avoid red meat, processed meats, bacon, sausage, egg-based dishes, and other dairy products.


Having a gluten-free diet can reduce the severity of psoriasis symptoms. Most autoimmune diseases may cause celiac disease responding to the gluten found in proteins. If so, psoriasis patients with heavy gluten intakes may experience increased markers on their bodies. Gluten sensitivity may lead to further complications as well. Thus, for any psoriasis patient with gluten sensitivity, the best choice is to remove gluten-rich foods from their diet completely. They must avoid foods like wheat, malt, rye, barley, noodles, pasta, baked goods, sauces, condiments, and beverages made from these products.

Processed foods

High intake of processed foods causes increased calorie consumption, leading to obesity. Additionally, you may suffer from metabolic syndrome and other chronic health conditions. These conditions may cause serious inflammation resulting in psoriasis flareups. The best diet for psoriasis avoids meats, canned vegetables and fruits, and any processed sugar intake such as caffeinated drinks.


Nightshades contain solanine that can trigger serious psoriasis inflammation in many people. The consumption of nightshades thus leads to serious psoriasis flareups. Therefore, it is important to avoid eggplants, potatoes, peppers, and tomatoes.

Alcohol intake

Alcohol is a serious psoriasis trigger as it disrupts your immune system. Drinking heavy quantities of alcohol can cause psoriasis flareups due to its impact on your immunity.

What foods can you consume in psoriasis?

Anti-inflammatory diets are the best choice for people who have psoriasis. Moreover, such diets are naturally full of antioxidants and can help reduce oxidative stress. The best diets comprise fruits, vegetables, and other natural foods like berries. Additionally, you may consume brussels sprouts, broccoli, cauliflower, kale, arugula, spinach, strawberries, raspberries, and blueberries apart from other dark fruits.

Fatty fish

A diet high in fatty wish will have a serious anti-inflammatory effect on your body. The fish contains omega-3s that reduce the inflammatory substances in your body. So, adding sardines, cod, trout, and salmon to your diet can help reduce psoriasis.

Heart-healthy oils

Olive oil, flaxseed oil, coconut oil, and safflower oil are all rich in antioxidants and omega-3 acids. Consequently, they help in the reduction of inflammation in the body.

Nutritional supplements

You may consume nutritional supplements such as vitamin D, vitamin B-12, and others as suggested by your doctor to reduce psoriasis. These nutrients help to reduce the severity of psoriasis-related inflammation.


To conclude, eating the right food can help reduce the symptoms of psoriasis. Try avoiding foods that may lead to inflammation or gluten reaction. Instead, I prefer food with anti-inflammatory effects due to the high quantity of useful anti-oxidants. Let us know in the comments section if our article was helpful.
