What are the dietary taboos caused by pityriasis rosea?

At present, the specific pathogenesis of pityriasis rosea is not completely clear. The most recognized trigger in the academic community is the activation of human herpes virus types 6 and 7, which are mostly related to short-term decline in immunity.； There is actually no unified "taboo list" in diet. The core principle is to avoid foods that make you uncomfortable, and there is no need to blindly abstain from eating them.

Some studies also believe that allergies, specific drug stimulation, and bacterial infections may also induce pityriasis rosea. However, the proportion of such cases is very low, and there is currently insufficient evidence to support a unified conclusion. Most of the patients I usually meet in the outpatient clinic have experienced staying up late, working overtime in preparation for exams, and catching colds in different seasons before they got sick. Just like the junior student who came here a while ago, he stayed up five nights in a row to catch up on his competition work, and he just caught a cold and had a low fever for two days. Immediately after the symptoms receded, a light red oval patch appeared on my chest with fine scales. I checked the viral antibodies and found out that the latent herpes virus had been activated. To put it bluntly, when your immunity is "offline", the "little viruses" hidden in the body will seize the opportunity to come out and cause trouble.

Many people's first reaction when they get a rash is to stop eating all "fat foods". They dare not touch seafood, beef, mutton, and mangoes. In fact, there is really no need to be so nervous. In the past, the traditional view did recommend that patients avoid such highly allergenic foods, but in recent years, more and more clinical data show that as long as you do not have allergic reactions when eating these foods, and the rash does not become redder or more itchy after eating, you can eat them normally. I once met a young man who only dared to eat plain boiled vegetables and rice for three weeks after the onset of the disease. He felt weak and weak. When he came for a follow-up examination, the rash had not healed at all. When I asked, I found out that he was not allergic to these foods at all. Instead, his immunity was not boosted due to long-term nutritional deficiencies, which slowed down his recovery. Later, he was allowed to eat normally, and the rash was completely gone in less than two weeks.

Of course, it doesn’t mean that you can make anything casually. Alcohol and particularly spicy food will dilate blood vessels in the skin. Regardless of whether you have allergies or not, eating them will most likely aggravate the redness and itching. It is better to avoid touching them as much as possible during the rash. If you are a person with allergies and feel the itching becomes more severe after eating foods such as seafood and mango, you can just avoid them for the time being. You don’t have to stop eating them for the rest of your life. You can still eat normally after the rash subsides. The disease itself is self-limiting, and most people will resolve it on their own in 6-8 weeks. There is no need to worry too much, and eating well and resting is better than anything else.
