The Role of Nutrition in Psoriasis Management

Proper nutrition plays a crucial role in managing psoriasis by supporting overall immune function and reducing inflammation. Incorporating nutrient-rich foods into your diet can help alleviate symptoms and promote skin health while avoiding certain trigger foods can further aid in minimizing flare-ups. You can read about the best and worst foods for psoriasis below:

Foods to Avoid with Psoriasis

Certain foods have been shown to exacerbate psoriasis symptoms and trigger flare-ups. It’s essential to limit or avoid the following foods to better manage your condition:

  • Processed Foods: Highly processed foods, such as sugary snacks, fast food, and pre-packaged meals, often contain trans fats and high levels of sugar and salt. These additives can promote inflammation and worsen psoriasis symptoms.
  • Alcohol: Excessive alcohol consumption can weaken the immune system and contribute to inflammation, potentially leading to psoriasis flare-ups.
  • Red Meat: Saturated fats in red meat are high, which can cause inflammation in the body and worsen psoriasis symptoms.
  • Dairy Products: Some individuals with psoriasis may experience problems from dairy products, particularly full-fat kinds because they can cause inflammation.
  • Nightshade Vegetables: Tomatoes, peppers, eggplants, and potatoes belong to the nightshade family and may exacerbate inflammation in certain individuals.
  • Refined Grains: Foods made from refined grains, such as white bread, white rice, and pasta, have a high glycemic index and can lead to spikes in blood sugar levels, potentially triggering inflammation and worsening psoriasis symptoms.
  • Artificial Additives: Foods containing artificial additives, preservatives, and food colourings can contribute to inflammation and may aggravate psoriasis in some individuals. It is important to choose whole, minimally processed foods.
  • High-Sugar Beverages: Sugary sodas, energy drinks, and excessive fruit juices are sources of added sugars that can promote inflammation and impact overall health, potentially influencing psoriasis flare-ups.
  • Shellfish: Certain shellfish, such as shrimp and crab, are high in iodine, which has been linked to exacerbating psoriasis symptoms in some people. Monitoring your intake of iodine-rich foods may be beneficial.

By avoiding these additional foods and following a balanced diet rich in anti-inflammatory options, you can help manage your psoriasis and reduce the risk of flare-ups.

On the other hand, incorporating nutrient-rich foods into your diet can have a positive impact on psoriasis management. Include the following foods in your meal plan:

  • Colourful Fruits and Vegetables: Vibrant fruits and vegetables are packed with antioxidants and vitamins that support a healthy immune system. Berries, citrus fruits, spinach, and kale are excellent choices.
  • Whole Grains: Foods like quinoa, brown rice, and whole wheat bread are full of fibre and nutrients that may help to improve gut health and possibly lessen inflammation.
  • Nuts and Seeds: Walnuts, flaxseeds, and chia seeds are sources of healthy fats and may have anti-inflammatory effects.

  • Avocado: High in monounsaturated fats and antioxidants, avocado can help reduce inflammation and promote skin health.
  • Sweet Potatoes: Beta-carotene, which the body transforms into vitamin A, can be found in abundance in sweet potatoes. Vitamin A is necessary for keeping skin healthy and may aid with psoriasis symptoms.
  • Broccoli: Sulforaphane, a chemical with potential anti-inflammatory properties that may be helpful for psoriasis, is present in broccoli.
  • Berries: Blueberries, strawberries, and raspberries are rich in antioxidants and vitamins, which can support a strong immune system and contribute to overall skin wellness.
  • Ginger: Due to its anti-inflammatory characteristics, ginger may help lessen psoriasis-related irritation. It can be used in recipes or drunk as herbal tea.
  • Olive Oil: Extra virgin olive oil is a healthy source of monounsaturated fats and antioxidants, such as polyphenols, which may have anti-inflammatory effects and support skin health.

Remember, while these foods may offer potential benefits for psoriasis management, it’s important to consult with a healthcare professional or registered dietitian before making significant changes to your diet, especially if you have any underlying medical issues or are taking any drugs. A balanced and varied diet, along with medical guidance, can play a key role in managing psoriasis symptoms.

Food Triggers for Psoriasis: Understanding Your Body

While there are general guidelines regarding foods to avoid and include in a psoriasis-friendly diet, it’s crucial to recognize that individual responses to foods may vary. Keeping a food diary can help you identify specific triggers that worsen your psoriasis symptoms. If you notice a pattern between certain foods and flare-ups, consider eliminating or reducing those foods from your diet. It’s important to note that triggers can vary from person to person, so what may cause a flare-up for one individual may not affect another. Additionally, it’s recommended to consult with a healthcare professional or registered dietitian who specializes in psoriasis to get personalized advice and guidance on managing your diet.
