What Food Should Psoriasis Patients Avoid


Psoriasis is a chronic skin condition that affects millions of people worldwide. It can cause significant discomfort and impact a person’s quality of life. However, managing psoriasis symptoms can be made easier with the proper diet. At Valley Skin Institute, we believe in a holistic approach to managing psoriasis, which includes guidance about diet.

Understanding Psoriasis

Psoriasis is an autoimmune condition that speeds up the life cycle of skin cells, causing them to build up rapidly on the skin’s surface. The extra skin cells form scales and red patches that are sometimes painful. While the exact cause of psoriasis is unknown, it’s thought to be genetic and related to an immune system issue with T cells and other white blood cells, called neutrophils, in your body.

The Role of Diet in Psoriasis

The role of diet in managing psoriasis, an autoimmune condition, is essential. The state of the body’s internal environment, primarily determined by what we consume, significantly influences psoriasis.

Diet plays a crucial role in managing psoriasis. Certain foods can trigger psoriasis flare-ups, while others can help reduce symptoms. An anti-inflammatory diet, rich in fruits, vegetables, lean proteins, and healthy fats, can help manage inflammation and ease psoriasis symptoms.

Foods to Avoid for Psoriasis Patients

Certain foods have been identified as potential triggers for psoriasis flare-ups. Here’s a list of foods that psoriasis patients might consider avoiding:

  • Processed Foods: Processed foods often contain high levels of unhealthy fats and sugars, which can increase inflammation. Inflammation is a key player in psoriasis flare-ups, making processed foods a potential trigger.
  • Red meat: Like processed foods, red meat is high in saturated fats, which can promote inflammation. Opting for leaner proteins, like fish or chicken, might be a better choice for individuals with psoriasis.
  • Dairy Products: Dairy products can also trigger inflammation. Some individuals with psoriasis might find their symptoms worsen after consuming dairy.
  • Gluten: Gluten, a protein found in wheat and other grains, can trigger inflammation in some individuals, particularly those with a sensitivity or intolerance to it. Some people with psoriasis have reported symptom improvement after adopting a gluten-free diet.
  • Alcohol: Alcohol can dehydrate the skin and trigger psoriasis symptoms. It also interferes with specific psoriasis treatments, posing a potential double threat.
  • Nightshade Vegetables: Some people find that nightshade vegetables, like tomatoes, peppers, potatoes, and eggplants, can trigger their psoriasis. This is thought to be due to a compound in these vegetables called solanine, which can cause inflammation.

Everyone is different, and what triggers one person’s psoriasis might not affect another’s. It’s always a good idea to keep a diary to identify potential food triggers and discuss them with your healthcare provider.

Healthy Alternatives for Psoriasis Patients

While certain foods can trigger psoriasis symptoms, others can help manage them. Here are some healthier alternatives that can be beneficial for individuals with psoriasis:

  • Fruits and Vegetables: These are packed with antioxidants that can help reduce inflammation, a key factor in managing psoriasis. They also provide essential vitamins and minerals that can boost overall skin health.
  • Lean Proteins: Lean proteins, such as fish, chicken, and tofu, are less likely to promote inflammation than red meat. Fish, particularly fatty fish like salmon and mackerel, also contain omega-3 fatty acids known for their anti-inflammatory properties.
  • Whole Grains: Whole grains, like brown rice and oatmeal, are high in fiber, which can help manage weight and reduce inflammation. They also contain B vitamins, which are beneficial for skin health.
  • Healthy Fats: Foods rich in healthy fats, such as avocados, nuts, and seeds, can help reduce inflammation. Olive oil is also a good source of heart-healthy monounsaturated fats.

Remember, everyone’s body responds differently to different foods. It’s essential to monitor your symptoms and adjust your diet accordingly.
