People with psoriasis have an increased risk of being obese which translates to a higher incidence of heart disease. Red meats and dairy products contain arachidonic acid. The acid has inflammatory properties. The appearance of psoriasis symptoms are sometimes the result of exposure to allergens. Citrus fruits, such as lemons and oranges, are common allergens which can lead to an allergic reaction that triggers a flare-up.
Alcohol causes the blood vessels in the skin to open, which can make it easier for T cells to make their way into the skin's outer layer. An increase of T cells is thought to be responsible for the development of psoriasis symptoms, as stated by Everyday Health. Even light alcohol drinking can exacerbate the symptoms of the disease. Fish is considered one of the best foods to eat for psoriasis. Fish can help reduce inflammation which is important for a person with psoriasis.
