Many psoriasis patients ask questions about their diet when they come to the clinic, such as “should I avoid eating”, “what can and cannot be eaten” and so on. There have been controversies in the medical field regarding the diet of psoriasis patients. Some doctors believe that the principle of “avoidance of food” should be strictly followed, others believe that appropriate avoidance of food is sufficient, and still others believe that food should not be avoided and should be left to nature. My opinion on the patient’s diet is that it is important to abstain from eating, but it is also important to have a variety of foods. Avoidance of food should be adjusted according to the individual differences of the patient and the changes of the disease period. Psoriasis is divided into three periods: progressive, quiescent and receding. According to the different periods, the diet of patients can be adjusted appropriately. 1. Progressive phase: Old skin lesions do not fade, new skin lesions keep appearing, or the original skin lesions keep expanding. During this period, it is necessary to avoid alcohol, seafood, spicy and stimulating foods (such as strong tea, coffee, etc.). It is advisable to eat a light diet with fresh vegetables (such as cabbage, carrots, eggplant, bitter melon, loofah, etc.), fruits (such as apples, pears, oranges, etc.), and foods rich in protein (such as milk, eggs, etc.). 2.Static phase: Stable lesions, no new lesions, reddish halo, less inflammation, the condition begins to improve. At this time, the dietary restrictions can be relaxed, according to their own needs to adjust the diet. However, you should still eat more fresh green leafy vegetables and fruits, as well as foods rich in high protein, etc. 3, the receding period: the old rash continues to fade, the scales become thin, broken and even disappear. At this time, patients can adjust their diet according to their actual needs. In addition to the dietary advice given by the doctor, it is more important for the patient to decide according to his specific situation. For example, some patients eat apricots to aggravate their condition, while others eat them but are fine. Therefore, psoriasis patients should pay attention to “different from person to person” and “different from situation to situation” in terms of diet.
