Patients with psoriasis often ask: Is it necessary to avoid eating and what should be avoided? My views are published here for your reference: 1. In general, there is no clear relationship between the condition or recurrence of psoriasis and diet, so there is no need to deliberately emphasize “avoiding food”; 2. Some doctors or so-called “doctors” make psoriasis patients avoid eating beef and mutton, seafood, spicy and other foods without evidence, which is not only unhelpful to relieve the disease, but also greatly reduces the quality of life of the patients and is undesirable; 3.A few patients find that their psoriasis will aggravate after eating certain foods or the itching will be more powerful. There are clear adverse effects, and these hobbies should be given up as far as possible.
