3. Try avoiding animal products.
In several studies, scientists have found psoriasis patients who avoid fatty red meats and dairy experience a reduction in psoriasis plaques. Metabolizing animal products (excluding fish) increases inflammation in our bodies, so sticking to veggies, fruits, and non-animal sources of protein cuts out this inflammation; plus, vegetables like carrots, garlic, onions, and broccoli contain high levels of antioxidants, which help to fight inflammation. However, you may want to stay away from the nightshade family of vegetables, like potatoes, tomatoes, and peppers, as they can increase inflammation.
