Lactose-free milk: what are the benefits and harms of the drink and how is it made?
Today, the dairy industry, in addition to ordinary milk, offers the buyer a large selection of products that have undergone various processing to meet certain requirements. In addition to the normalized or reconstituted product, lactose-free milk can be found on sale, which occupies a separate segment in the line of the presented product range.
What it is?
Most often, lactose-free milk is sold by large supermarkets, since the product has not yet received widespread distribution. The product raises some concerns among buyers due to erroneous assumptions regarding its synthetic composition. In fact, when you get acquainted with this topic, you can understand that the product is completely natural, and the need for the presence of such products on the grocery shelves of stores is due to a number of physiological characteristics of the human body.
A perfectly healthy person can consume milk and dairy products without risk to health., and people diagnosed with lactase deficiency are limited in this. Indiscretion in such a matter for them is fraught with problems with digestion and disorders in the digestive tract.
Based on statistics, about 18-20% of the Russian population has lactose intolerance.
There are two problems that are closely related: milk allergy - an allergic reaction of the immune system to proteins in milk (proteins) and lactose intolerance, which occurs due to the body's reaction to milk protein as foreign - when there is difficulty digesting lactose, which is a natural sugar contained in milk. The consequences after taking milk or other dairy products in this embodiment are similar to signs of poisoning, in some cases skin rashes are observed.
Lactose intolerance is characterized by the characteristics of the body, due to which it is not able to digest saccharide. After lactose enters the stomach and intestines, its splitting does not occur. This is dangerous because milk sugar is a favorable environment for the reproduction and development of various bacteria in the body. This problem is especially acute in children, since these features affect slow growth and malfunctions of the gastrointestinal tract.
Carbohydrate intolerance to varying degrees with age occurs in the body of each person, progressing with aging. In some cases, the disease is not congenital, but develops after an intestinal infection.
Lactose-free milk can be cow, sheep or goat. On sale you can also find dairy products of this type, made from rice, soy or coconut raw materials.
Milk sugar is removed by membrane separation, resulting in the breakdown of lactose into glucose and galactose.
In addition, some companies make low-lactose milk, in such a product the content of the substance is no more than 0.01%.In terms of taste, lactose-free milk is sweeter than regular milk. This is due to the fact that the decomposed substances are simpler components, which contributes to their increased sweetness.
The composition of lactose-free milk is similar to the usual pasteurized product. It includes a fairly extensive complex of vital vitamins, organic acids, mineral components, among which it is worth highlighting beta-carotene, vitamin C and D, choline, B vitamins, nucleic acids. An important role in the composition is played by calcium and fluorine, sulfur, sodium and phosphorus. In addition, the product contains protein, which is important for the overall satiety of the body and the development of muscle mass.
The fat content, as a rule, remains unchanged, and is 1.5%. Lactose-free milk is considered low-calorie because it contains only 39 kcal.
The shelf life of the product depends on the manufacturer, but on average, it does not exceed 8 days from the date of manufacture. If milk is sold in a tetra pack, its shelf life is extended and is usually within a few months.
How do they receive?
The production of lactose-free milk has been mastered by some domestic and many foreign companies.
Today, several modern technologies are used to manufacture products.
- The process of fermented digestion of lactose. It involves the introduction of a special component into whole milk - lactase, which, interacting with lactose, breaks it down. As a result, the fat content of the product drops to the minimum values, due to this, about 98% of lactose is split.It should be understood that milk obtained in this way cannot be called a product completely freed from milk sugar, therefore manufacturers label it accordingly. As a rule, milk is positioned as low-lactose.
- Obtaining lactose-free milk is also carried out using a special fermented milk culture.
- The membrane filtration method involves the treatment of milk by ultrafiltration on a special membrane. The result of such work is the production of a low-lactose product, with an enzyme content of 0.01%. At the final stage, the final elimination of lactose occurs by lactase, which is taken from certain mushrooms.
What is useful?
Despite the high cost of lactose-free dairy products, the benefits of using the product for health reasons or based on other nuances justify its cost.
To get an objective picture of the effect of milk on the human body, it is worth considering the main positive features.
- First of all, it is necessary to note the main feature of the product - milk is hypoallergenic. This means that lactose, which is completely absent or in a minimal amount in its composition, will not provoke an allergic reaction after consuming the product.
- Despite the technological features of the manufacture of products, it retains all minerals and vitamins.
- According to reviews, a decrease in the content of glucose in milk has a positive effect on the process of digestion of the product. In addition, side effects such as flatulence, nausea, rash are excluded.
- When breastfeeding, the use of lactose-free milk can reduce the risk of digestive problems in infants.
- A balanced and enriched composition of the product, when introduced into the diet, will have a positive effect on the functioning of the digestive organs and metabolism, and help strengthen muscle tissue.
- Vitamins, micro and macro elements have a beneficial effect on the functioning of the cardiovascular system, strengthen teeth, nails and hair. In addition, there are improvements in the functioning of the nervous system, milk helps to get rid of insomnia. Of the main sources of health, it is worth highlighting calcium, which is found in lactose-free milk. It is known to act as a fundamental building block of the whole organism. Protein has a beneficial effect on metabolism, potassium contributes to the normalization of water balance. Of great importance is vitamin D, whose task is to ensure the productive process of assimilation of calcium by the body. Vitamin A is needed to strengthen immunity, visual acuity and healthy skin. B group vitamins are necessary for the functioning of hematopoietic organs, maintaining the nervous system, in addition, substances take an active part in the metabolism of BJU, regulate metabolic processes.
- A positive trend can be noted when the product is included in the diet of various diets, since the calorie content and carbohydrate content of milk are much lower compared to those of whole milk. With the introduction of lactose-free milk into the diet, the results from the diet will be more noticeable, and there will be no need to significantly reduce the consumption of products. There are a number of diets, for example, cottage cheese, where the product is prepared from lactose-free milk. They show great results.
- For women during pregnancy, milk is a very valuable product that affects the development of the fetus. Ordinary milk can be uncomfortable because the digestive system can't handle it at certain times. During this period, low-lactose or lactose-free milk will become an indispensable product.
- Lactose intolerance is common in children and newborns. Especially for this segment of consumers, lactose-free mixtures are produced to replace breast milk and provide good nutrition for a growing body. Among the main components of lactose-free baby food is glucose syrup, which is much easier to digest, a certain complex of fatty acids and nucleotides that contribute to good immunity to diseases.
For feeding babies, the product is available in powder form, in the form of dry mixes.
Contraindications and harm
Lactose-free milk belongs to the category of food products that do not pose a danger to the body. Unexpired store products, produced with strict observance of the entire complex of sanitary and hygienic measures, cannot be harmful to health.
Milk, even with a low lactose content, is not recommended for use if a person has an allergic reaction to cow's milk protein.
Separately, it is worth noting the possible harm associated with the use of various antibiotics and other drugs in modern animal husbandry that increase milk yield. Although these substances are usually destroyed by heat treatment, some constituents may still remain in the product.And with lactase deficiency, the enzymes present in the human gastrointestinal tract will not be enough to break down hormones of protein origin.
Recommendations for use
At the moment, the product is not so popular among buyers, since it appeared on the shelves relatively recently, in addition, foreign companies are mostly engaged in its production, the domestic manufacturer is only entering the market with similar products.
The main category of consumers of lactose-free milk is still people with lactose intolerance. Milk can be consumed in the normal state in which it is sold, in addition, it can be boiled, prepared on the basis of the product for desserts, cereals or pastries, added to drinks. Boiling is not a prerequisite prior to the introduction of the product into the diet. This is due to the fact that the entire technological cycle of manufacturing products takes place under antiseptic conditions, so the presence of bacteria or microorganisms hazardous to health in it is excluded.
In addition, it should be noted that milk is considered to be very susceptible to heat treatment. Under the action of high temperatures, a certain amount of protein coagulates, precipitating along with mineral salts, some vitamins in the product become less. Pathogenic microorganisms are destroyed during pasteurization, therefore, additional boiling of the product is not required, provided that it is not planned to cook any dish that requires boiling. And pasteurization is an obligatory stage of any process of release and production of milk and products containing milk.
Drinking a lactose-free product is recommended for general strengthening of the body, since its benefits for humans are similar to drinking regular pasteurized milk. Nutritionists advise to make the intake of dairy products daily, but at the same time observing some norms.
Amounts and portions vary according to age.
- For a child's body from birth to a year, whole cow's milk cannot be introduced into the diet. An exception is the presence of lactose intolerance, in which case lactose-free children's dry powders (mixtures) are used to feed the baby, which the baby receives in the norms indicated by the pediatrician.
- From one year to three years, the volume of milk in the daily diet of children is not more than 500 ml.
- As for the period from three to thirteen years, there are no restrictions regarding the amount of milk and dairy products consumed.
- It has been established that after the age of thirteen, processes occur in the human body, as a result of which the level of the content of such an enzyme as lactase is significantly reduced. Based on this feature, it is best to focus on sour-milk low-lactose products.
- A number of recommendations for an adult organism can be noted - up to the age of thirty, the optimal amount of milk consumed will be 2-3 glasses, after thirty the norm is reduced to two glasses, after forty-five - up to one glass of milk or fermented milk product per day.
Of course, the data described above are only advisory in nature., therefore, taking into account certain individual characteristics of the organism, they can change.The main factor to rely on in determining the amount of milk consumed is the general well-being of the body, as well as the absence or presence of various reactions of the body to dairy products.
In fermented milk products, such as cottage cheese or cheese, the amount of milk sugar is greatly reduced because the fermentation bacteria break down the disaccharide. That is why milk derivatives with serious lactose intolerance in humans will be an excellent and complete alternative to milk.
