Symptoms of milk protein intolerance

Nutritious substances in life are definitely good, but good does not necessarily mean suitable for everyone. For example, milk protein is generally very helpful to the body, but some people in life are not adapted to it. What does it mean to be inadaptable? What are the symptoms of inadaptability? The following article will talk about the symptoms of milk protein intolerance.

Also known as milk protein. It is a general term for a mixture of many kinds of proteins in milk. It is mainly composed of two parts: casein and whey protein. The former is the protein precipitated from milk at 20°C and pH 4.6, and the remaining protein dissolved in whey is called whey protein. Whey protein includes β-lactoglobulin, α-lactalbumin, serum albumin, immunoglobulin and other trace proteins, such as copper, zinc-superoxide dismutase, etc. Except serum albumin and immunoglobulins which come from blood, all caseins and whey proteins are synthesized by milk-secreting cells in the mammary gland. With the determination of amino acid sequences of most milk proteins, many variants of milk proteins have been discovered. Milk protein is mainly used as a food additive.

Cow's milk protein intolerance refers to an abnormal immune response induced by proteins in milk (mainly whey protein and casein) mediated by IgE, non-IgE or mixed. IgE-mediated immune responses are mediated by mast cells and alkaliphils. Non-IgE mediated immune response caused by eosinophilia.

If you have symptoms of milk protein allergy or lactose allergy, you can make the following judgments and treatments:

1. If you suspect lactose intolerance, you can test the lactose in the stool or the galactose in the urine, which is very convenient. There is also a hydrogen breath test, which is not suitable for infants. If you are lactose intolerant, you need to eat lactose-free milk powder or add lactase.

2. If you suspect you have a milk protein allergy, you can perform a skin prick test, food provocation test, etc. Treatment requires dietary avoidance, and if there is no improvement, feeding with deeply hydrolyzed protein or amino acid formula milk is required.
