牛奶過敏是由牛奶蛋白引起的一種免疫系統反應。當身體錯誤地認為牛奶蛋白是人體的有害物質，身體就會製造對付牛奶蛋白的抗體。當下一次的身體接觸到牛奶或含牛奶的乳製品，免疫系統會釋放出大量的化學物質，包括組織胺和抗體來保護身體。這些化學物質會引發一連串的過敏症狀。而這些過敏症可影響嬰兒的皮膚，胃，呼吸和血壓。
   選用牛奶配方的嬰兒，可以切換大豆蛋白配方的豆奶。但如果嬰兒不耐大豆，就應該選擇低過敏性配方或自由氨基酸配方，因為當中的蛋白質被分解成更小的微粒，所以這些低過敏性配方或自由氨基酸配方是可以減少引發過敏性的反應。 食用母乳的嬰兒，牛奶中的蛋白質可能是從母親轉移到過敏的嬰兒，因此，哺乳期的母親應該戒掉奶類食品，停止牛奶蛋白由母乳輸送給嬰兒。  抗組織胺藥是非常有效地可以減輕過敏的反應，如皮膚瘙癢。而含有類固醇的藥膏雖然是對濕疹很有功效，但長時間使用，可能會令皮膚受損。  把牛奶戒掉6個月是一個非常漫長的過程，但它的確是一個最有效的方法去減少牛奶過敏引起的過敏症狀。然而，當飲食缺乏牛奶的時候，就要給身體補充一些營養以滿足身體營養的需求。 第一項要注意的是在飲食中得到足夠的鈣。牛奶的替代品，如豆漿，可以選擇加鈣的豆漿。當嬰兒開始進食固體食物，應選擇含有高鈣的食物。包括綠色蔬菜（西蘭花，椰菜），有軟骨的魚（三文魚和沙丁魚）和海洋（蠔和蝦）。 身體一旦缺乏維生素 D就不能吸收鈣質。維生素 D的來源包括：雞蛋，動物肝臟，和陽光。 
 Milk allergy is an immune system response to milk protein that the body mistakenly believes is harmful. Once the immune system decides that milk protein is harmful, it creates specific antibodies to it. The next time the individual drinks milk or consumes dairy products containing milk, the immune system releases massive amounts of chemicals, including histamine and antibodies, in order to protect the body. These chemicals trigger a cascade of allergic symptoms. Anaphylaxis can occur and affect the baby's skin, stomach, breathing, and blood pressure.  For formula-fed infants, you may switch to soy-protein based formula. If infants cannot tolerate soy, you should choose a hypoallergenic formula or free amino-acid based formula, in which the proteins are broken down into smaller particles so that the formula is less likely to trigger an allergy reaction. For breastfed infants, the milk protein may be transferred from the breastfeeding mother to an allergic infant, therefore lactating mothers should put on an elimination diet to stop the milk protein crossing to the breast milk.  Antihistamine drugs are very effective in calming down the allergy reactions, such as itching. Creams containing steroids are useful for eczema but prolonged use of them may damage the skin. 
 Although eliminating milk in the diet for 6 months is a very long process, it is the most effective way to reduce allergy symptoms caused by milk allergy. However, without milk in the diet, the nutritional needs of the body need to be met. The first concern is to get enough calcium in the diet. For milk substitute, such as soy milk could be chosen with added calcium. When babies are ready to begin eating solid foods as a complement to milk, foods containing excellent sources of calcium should be chosen. This includes green vegetables (broccoli, cabbage), fish with soft, edible bones (salmon and sardines), and seafood (oysters and shrimp). Calcium can not be absorbed without Vitamin D. Sources of Vitamin D include eggs, liver, and sunlight.  我們現已登陸facebook！全新HK BioTek專頁將配合facebook全新打咭功能，為會員提供不同優惠。除此之外，HK BioTek將繼續透過本平台，提供不同健康資訊。關注健康的您絕對不容錯過，請按此獲得詳細資料。HK BioTek is now on facebook!
