Difference between lactose intolerance and milk protein allergy
1. Etiology: Milk protein allergy is caused by the immune response of human immune system to milk protein, while lactose intolerance is caused by the inability of human digestive system to fully digest and absorb lactose.
2, symptoms: milk protein allergy can appear in skin, digestive tract, respiratory tract and other aspects, lactose intolerance will mainly appear digestive tract symptoms, the most common is persistent diarrhea.
3. Diagnosis: It should be based on diet-related medical history, and there are many auxiliary examination methods to assist the diagnosis.
What about lactose intolerance?
1. Drink milk in batches
People who are lactose intolerant can divide a box of 250 ml milk into three parts to drink. Although this will be a bit troublesome, it can effectively reduce lactose intolerance.
2, milk to yogurt
Lactose in the same amount of yogurt is less than milk 1/3, so people's tolerance to yogurt naturally becomes better, and they can drink the same amount of yogurt instead.
3. Eat lactase before drinking milk.
In foreign countries, many supermarkets will put lactase beside the shelves selling milk, which is for people who are lactose intolerant. Eat lactase first, then drink milk. This method is worthy of reference.
Step 4 choose lactose-free dairy products
Shuhua milk and lactose-free milk powder are both dairy products that remove lactose from milk. Both calcium and protein are found in lactose-free dairy products. In fact, lactose in milk can promote the absorption of calcium. Don't choose lactose dairy products unless you are too sensitive to lactose.
How to treat infant milk allergy?
Through the detection of allergens, if the baby is really allergic to milk protein, how should it be fed and treated? Avoid foods containing milk. Infants with milk allergy should adopt diet exclusion therapy, that is, strictly avoid eating food containing milk ingredients in the next 3-6 months. Not only ordinary formula milk powder can't drink ordinary formula milk, but also foods containing milk protein, such as cream cake, bread, salad dressing, colostrum and milk candy, until the result of "exclusion-excitation test" turns negative. So, how should breast-fed babies and formula-fed babies arrange their diet? Breastfeeding? Although breastfeeding mothers can't drink milk. Although breast-fed babies are unlikely to be allergic, there is also the possibility of milk protein allergy. If the baby is allergic to milk, the mother should avoid dairy products in her diet for 4 days. If the baby's allergic symptoms are relieved, the mother should continue not to eat dairy products and supplement calcium when necessary to avoid calcium deficiency.
skill
Babies without diarrhea symptoms can drink formula powder containing lactose. Parents who are allergic to milk protein will naturally be more cautious when taking care of them. Many parents will have such questions when they see this: Can the special formula powder containing lactose be given to the baby who is allergic to milk protein? The first thing to understand is that there are three basic substances in formula milk powder: protein, fat and carbohydrate. Protein is the center to distinguish amino acid formula, deep hydrolysis formula, moderate hydrolysis formula and ordinary formula. However, many companies will remove lactose when producing deep hydrolysis and amino acid formula powder, because they are worried that the baby will not be tolerant of lactose. Now another study says that not all children who are allergic to milk protein will be lactose intolerant, so some special formula powders add lactose back. Secondly, parents need to understand that lactose intolerance and milk allergy are two different things. Glucose and galactose combine to form lactose. This disaccharide cannot be directly absorbed by the human body. An enzyme must cut them off. This enzyme is called lactase. Lactase is located on the surface of small intestinal mucosa. If the intestinal mucosa is normal, lactase will exist, and lactose molecules can be cut into glucose molecules and galactose molecules, and then absorbed into the blood by the intestinal mucosa to generate energy. If allergies cause intestinal damage, formula powder containing lactose should not be used. If the small intestine functions normally, it can be considered. In other words, if a child's allergic symptoms are only skin manifestations such as eczema, or respiratory manifestations such as asthma, such a baby can drink special formula containing lactose, but as long as the allergic baby has diarrhea or bloody stool, it cannot be drunk.
