More and more people are suffering from allergic problems such as eczema, asthma, and allergic rhinitis. Allergies have become an unavoidable topic for people every year. In addition to avoiding allergens and medication, a scientifically sound nutritional strategy is the third pillar in preventing and treating allergies. Today, let's explore together how to help allergy sufferers alleviate symptoms and improve their quality of life through daily dietary adjustments. Allergies can manifest in various ways when the immune system overreacts to typically harmless substances such as dust mites, pollen, mold, and certain foods. The symptoms of allergies can be mild or severe - from repeated sneezing to fatal shock, from skin rashes to the risk of suffocation. This lurking health "assassin" affects almost all age groups, from infants to adults. Allergic symptoms vary greatly: from sneezing, nasal congestion, wheezing in the respiratory tract, to eczema and urticaria on the skin, to abdominal pain and diarrhea in the digestive tract, and in severe cases, it may even trigger life-threatening systemic allergic reactions - severe allergic reactions. The close relationship between allergies and nutrition has been overlooked. Nutritional intervention plays a multidimensional role in allergy management: strengthening barrier function, nutrients such as vitamin A can maintain the integrity of the skin and mucous membranes, and reduce allergen invasion. Regulating immune balance with probiotics, Omega-3 and other ingredients can regulate immune responses and avoid excessive inflammatory reactions. Quercetin and other plant compounds can alleviate allergic symptoms by inhibiting histamine release and reducing discomfort such as sneezing and itching. Preventing severe attacks with balanced nutrition can enhance the overall resistance of the body and reduce the risk of severe allergic reactions. The four major nutrients build an anti allergy wall. Food is also known as "good medicine". In daily diet, there are four major categories of nutrients that are particularly important for allergy patients. They together form the 'nutritional backbone' of an anti allergy diet. The vitamin family is the guardian of the mucosal barrier. Among them, vitamin C plays a key role in tissue repair and immune system operation, and has been proven to improve allergy or asthma symptoms. Vitamin C is present in various fresh vegetables and fruits, such as guava, kiwi, and bell peppers, but it should be noted that high-temperature cooking can damage their activity; Vitamin A can maintain the integrity of human epithelial mucosal cells and reduce the invasion of allergens. If you are concerned about excessive intake of vitamin A directly, you can choose ingredients rich in beta carotene, such as dark green, orange, and red vegetables and fruits. When consumed in moderation with oil, it can increase absorption rate; Vitamin D has a good effect on regulating immunity and reducing inflammation. There are relatively few natural sources, mainly found in egg yolks, animal liver, deep-sea fish, and mushrooms that have been exposed to sunlight. Moderate sunlight exposure is also an important way to obtain vitamin D. Omega-3 fatty acids are a natural anti-inflammatory defender. Omega-3 fatty acids have significant anti-inflammatory effects, can reduce the production of inflammatory substances during inflammation and allergies, and can also prevent bronchial constriction and improve asthma. Deep sea fish are a high-quality source of natural Omega-3, and it is recommended to consume them 2 to 3 times a week. Vegetarians can choose flaxseed, walnuts, etc. Master of regulating gut immunity with probiotics. 60% of the immune system is in the gut, and a healthy gut also has a relatively stable immune system. Probiotics, as beneficial bacteria, can help us adjust the gut microbiota and reduce the risk of allergic reactions. Fermented dairy products with added live bacterial preparations and naturally fermented foods such as kimchi and natto are good dietary sources of probiotics. It is worth noting that long-term use of antibiotics and a high sugar diet can disrupt the balance of gut microbiota and increase the risk of allergies. Phytochemical anti allergy special forces. Among them, quercetin can inhibit the secretion of histamine by mast cells during allergic attacks, thereby reducing allergic symptoms such as sneezing, runny nose, and skin itching. Onions, apples, tomatoes, grapes, and berries are all rich in quercetin. Polysaccharides are mainly found in mushroom like foods such as shiitake mushrooms, shiitake mushrooms, and black fungus. They can activate the immune system, regulate immune function in both directions, and help improve and prevent allergic symptoms. Wen/He Yuan (Beijing Shijitan Hospital) (News Agency)
