Breast milk

The best food for the newborn

Breast milk is the most recommendable food for the newborn, as it provides all the nutrients but above all contains them in the right proportions. This is valid for all mammals; cow's milk will therefore be ideal for the needs of the calf but it will not be the same for those of the newborn.

In the woman, as well as in the cow, we can distinguish three different moments of lactation. From the first day after the birth until the fifth - sixth day, the so-called colostrum is produced, a milk particularly rich in proteins and mineral salts; this is because the baby, immediately after giving birth, accuses a physiological decline mainly due to the loss of fluids, since in the last nine months he had lived in an aqueous environment. Furthermore, birth represents a traumatic event and as such leads to an increase in energy expenditure. The child therefore needs to recover energy quickly, through a milk, colostrum, rich in proteins, mineral salts but also and above all in antibodies, such as immunoglobulins, lactoferrin, white blood cells and lysozyme.

Since its immune system is not yet effective enough to deal with them on its own, the antibodies help the young organism to fight the environmental pathogens it comes into contact with. Breast milk therefore represents a very important and irreplaceable food which, in addition to the aforementioned immune action, positively stimulates the functionality of the baby's digestive organs.

After the first five or six days after delivery, breast milk begins to change its composition. For this reason we no longer speak of colostrum but of transition milk; the quantity of proteins and mineral salts is reduced, while the percentage of sugars and lipids becomes more generous. These variations are very important because the energy needs of the newborn, understood as calories per kg of body weight, are maximum in the first month of life.

Fifteen days after giving birth, the milk has reached a standard composition, which will be maintained until weaning. This milk, defined as mature, is rather rich in lipids and carbohydrates, but with a lower percentage of proteins and mineral salts.

Colostrum, Transition Milk, Mature Milk

THREE TYPES OF BREAST MILK are distinguished:

COLOSTRO: produced from the 1st to the 6th day of the child's life, it is extremely rich in nutritional factors such as proteins, mineral salts and oligosaccharides; it also contains antibodies, white blood cells, lysozyme and complement factor.
TRANSACTION MILK: produced from the 6th to the 14th day: it increases the percentage of fats and lactose (therefore the caloric intake) and decreases the percentage of proteins and minerals.
RIPE MILK: produced from the 15th day onwards.

If for the baby breast milk represents an irreplaceable food, breastfeeding is particularly useful for the new mother:

sucking in fact stimulates the production of a hormone, called oxytocin, which acts by contracting the uterus and helping it to return to physiological conditions.
The production of milk leads to a moderate increase in energy expenditure (a natural aid to regain the line after the months of pregnancy).
Breastfeeding also seems to protect the mother from osteoporosis and according to some studies would also reduce the risk of breast cancer (however, these are epidemiological data, to be taken with statistical significance).

Properties of breast milk

Nutritive: presence of proteins, lipids, mineral salts and sugars in quantities and proportions adequate to the needs of the infant. The only element slightly deficient is iron; it must be said, however, that during the prenatal period the baby builds up stocks that allow him to face the long breastfeeding period without going against specific deficiencies. In addition, iron deficiency in breast milk could be a strategy developed by nature to protect the overgrowth of harmful bacteria in the intestine, such as"Escherichia coli which depends on it, facilitating that of the symbiotic lactobacilli that protect the baby's organism from infections.
Breast milk is ascribed a preventive role in the onset of premature obesity. The concentration of fats in fact tends to increase towards the end of the feed, inducing a feeling of satiety in the baby. This, of course, does not happen when feeding artificial milk. .
Anti-infectious: the nutritional aspect of breast milk can be approached, even if not perfectly equaled, by artificial milks. The properties that are in no way reproducible are the immune ones. Thanks to the presence of white blood cells, anti viral antibodies and specific antibodies, breast milk protects the newborn from pathogens present in the external environment; moreover, the content of lactoferrin, lysozyme and immunocompetent cells favors the development of beneficial intestinal bacteria, helping the little one to eradicate the pathogens responsible for gastroenteritis (colic of the newborn);
Anti-allergic: linked to the presence of immunoglobulins (IgA); with rare exceptions, there are no cases of allergy to breast milk. On the contrary, breastfeeding seems to protect the baby from food allergies in adulthood; this is because it delays the first contact with food, giving the immune system time to develop.
In addition to the absence of economic weight, breast milk has the power to improve the mother-child relationship and is always ready for use, fresh and at body temperature.

For all these reasons, unlike what happened between the 1960s and 1970s, the importance of breastfeeding and breast milk is strictly protected by legislation, including in advertising matters.
