    There is no universal list of must-eat foods for allergic dermatitis. The core principle is to eat foods that you are clearly not allergic to, mild and low-irritation, and give priority to regular foods with strong anti-inflammatory properties. You don’t need to blindly avoid food until you are left with white porridge, and don’t believe in miraculous foods that “can desensitize you after eating them.”

    I met a 27-year-old girl a while ago. Pollen induced allergic dermatitis on her face in the spring. Her face became red, hot, and itchy. I heard others said that eating more fruits to replenish vitamins was good, so I ate mango and pineapple. As a result, the more I ate, the more swollen she became. I checked the allergens and found out. She said that she was intolerant to fruits of the Anacardiaceae family. Later, she stopped being allergic to these fruits and ate her usual fried vegetables, steamed lean pork, and seasonal apples and pears. She did not even increase the amount of antihistamines, and the redness and swelling were almost gone in more than a week.

    Many people will ask if they can eat more foods high in vitamin C? In fact, this is still a bit controversial. Some clinicians believe that eating more high-VC foods such as fresh dates and ordinary kiwi fruits during the stable period can reduce blood vessel permeability and reduce redness, swelling and exudation. However, some people believe that if you have a photosensitive constitution or suffer from photosensitive allergic dermatitis, eating too much of these high-VC photosensitive foods and then exposing yourself to the sun will aggravate the inflammatory reaction, which is counterproductive.

    In fact, many people want to avoid all "fat foods" when they get dermatitis. It's really unnecessary. I met a guy who worked in IT before. After he got dermatitis, he didn't even dare to put in more salt. He only ate white porridge and boiled vegetables for three days. After eating it for three days, he was so weak that he couldn't even type code. When I came for a review, I It’s hard to laugh or cry. As long as it’s ingredients you’ve eaten without problems before, there’s no need to have any additional dietary restrictions. If you consume enough protein, your skin barrier can be repaired quickly. Just like a child who has a tantrum, you don’t need to force-feed them new and high-end supplements. It’s safest to give them something familiar and non-irritating.

    If you haven't checked your allergens and don't know what you are allergic to, you can avoid common highly allergenic foods such as seafood, mango, pineapple, alcohol, and spicy seasonings during the attack period. When you are not sure what to eat, choose basic ingredients that most people are not allergic to, such as winter melon, steamed chicken, cabbage, rice and steamed buns. After the inflammation subsides, slowly add new ingredients one by one, and you can easily find your minefield.

    By the way, don’t believe what food can cure allergic dermatitis. An aunt heard from a group that eating broccoli can desensitize her, so she stopped taking antihistamines without permission. As a result, after three days, her face was so swollen that she couldn’t even open her eyes. Instead, she was hospitalized for three days. Food is at best a supplement. To reduce inflammatory reactions, you should still take the medicine as directed by your doctor. If you are too lazy to check allergens, you can also keep a simple food diary. If you eat something that makes it more itchy or red rash, write it down and avoid it next time. It is much more reliable than copying other people's taboo lists.
