I am often asked by psoriasis patients: What should I pay attention to in terms of diet? Do I need to avoid eating during treatment or in general? Psoriasis is a chronic skin disease with inflammatory characteristics. Patients with psoriasis should eat a reasonable diet, maintain a balanced nutrition and improve the body’s immunity. Because psoriasis is an immunodeficiency disease, it is helpful to improve immunity for early recovery from psoriasis. And adequately replenishing the body with the required nutrients and enhancing resistance is an important way to improve immunity. So what should psoriasis patients pay attention to in their diet? In life psoriasis diet should be reasonable, comprehensive and balanced to provide the necessary nutrients, enhance the immune system, increase resistance, in daily life, eat more fresh vegetables and fruits, but also more exercise to improve their immunity and prevent relapse. Vitamin A is also very important for the formation of connective tissues. Zinc promotes the action of vitamin E and carotene; vitamin C, which promotes collagen synthesis, anti-inflammatory, consolidates connective tissues and maintains healthy muscles and skin; B vitamins, which are involved in the metabolism and synthesis of substances, help other nutrients to function and relieve patients’ stress and tension. When the body is deficient in vitamin A and B vitamins, it is easy to cause rough skin. Therefore, you should eat more food and fruits that contain vitamins, water and fats. In addition to actively cooperating with doctors in treatment, psoriasis patients should also pay attention to the taboo in daily life: avoid alcohol, seafood and spicy food. There are different opinions about avoidance of mouth. Some people believe that avoidance of mouth should depend on individual differences, and avoidance of mouth will cause the body to lose a lot of nutrients, which is not conducive to the improvement of the disease.
