THERE IS no DOUBT that maternal milk is superior to the one of cow, reason why the maternal lactation is due to advise, although artificial milk, that the industry prepares nowadays with a composition similar to the one of human milk, are without a doubt in conditions for guaranteeing to the boy a suitable feeding.
At the moment one grows up to a high one I number of children with artificial milk, fundamentally milk of cow more or less modified, with satisfactory and even optimal results.
It seems that it can be deduced of it that human milk and the vaccine could be considered equivalent.
Nevertheless, in fact, this conclusion is not totally certain.
At great length let us see the differences between two milk and their meaning in relation to the feeding of the boy.
Proteins.
Human milk has a protein content of 12 grams by liter; the vaccine of about 35 grams If it is analyzed which are the proteins contained in both types of milk, is observed that the cow milk has a much more high casein content that the human one.
The casein is the protein of the milk that forms the clot.
The part that is floating in maternal milk, this is, the serum of milk, contains the lactalbumin and the lactoglobulina.
In absolute terms, the amounts of these proteins in both milk are similar. Nevertheless, in relative terms, human milk upper has a content in lactalbumin and lactaglobulin.
This difference in the protein composition of both milk is important for different reasons. From the point of view of the digestion, the greater casein content of bovine milk is responsible for the formation in the stomach of greater clots, whereas human milk gives rise to smaller clots.
The digestive enzymes find greater difficulty at the time of attacking the clots of the cow milk, that are therefore more difficult to digest.
On the other hand, the coagulated mass that forms the cow milk advances slowly by the intestine, reason why the water and the lactose are reabsorbed to a great extent in the first portions of the intestine and, therefore, they do not reach the colon.
The clot that forms maternal milk, however, can cross the thin intestine quickly. In this way, the water and the lactose arrive at the colon, fact this one that facilitates the presence of a more beneficial intestinal flora for the human organism.
The difference between maternal and bovine milk also talks about to the composition of proteins in both types of milk, that is to say, to its content in amino acids.
In the boy fed with cow milk, the different composition from this discharges to place to numbers of total plasmatic amino acids more from the hospital, to an excess of certain amino acids and a deficiency of others.
Thus for example, in the bred children with cow milk much more high numbers of tirosina are registered that those that is observed in the children who take maternal milk, with negative consequences on the central nervous system.
On the contrary, the cow milk is poor in bullfighting and cístina. Finally, the greater protein content of the cow milk supposes greater work for the kidneys.
Sugars.
Human milk and the milk of cow contain he himself sugar, the lactose.
Nevertheless, more lactose in the human milk exists much (7 grams by liter) that in the cow milk (4.8 grams by liter).
The lactose is disaccharide, that is to say, a sugar constituted by two simple sugar molecules (monosaccharides): one of glucose and another one of galactic.
The importance of an elevated lactose presence in human milk is double.
On the one hand, it is very probable that it constitutes a positive factor for the development of a more favorable intestinal flora for the organism.
By another one, the galactic (that, like is saying, is one of both monosaccharides of the lactose) is essential for the synthesis of the cerebrosides ones, complex substances that comprise of important structures of the nervous system. ~ nervous system is not mature at the moment of the birth.
Therefore, it is important that this system receives through the feeding the necessary substances for its development.
In effect, one has demonstrated that in many species of mammals it exists a parallelism between the amount of the lactose content of milk and the speed of growth of the central nervous system.
Fats.
Inasmuch as it concerns to fats, great difference between the milk of cow and human milk does not exist in quantitative terms.
In effect, the greasy content is equivalent to 3.8 grams in human milk and to 3.7 grams in the cow milk.
However, yes differences as far as the qualitative composition exist. Most important of them it consists of the presence in the human milk of an amount of linoleic acid much more elevated that in the cow milk.
The linoleico acid is the only fatty acid that must be present, since the boy is not able to synthesize it, but he needs it for his metabolism.
Another data that is possible to emphasize is the fact that the relation between insaturades fatty acids and saturated fatty acids is different in two milk: in effect, human milk is richer in insaturades fatty acids.
This relation conditions a more or less high cholesterol content in the plasma, that, as well, has great importance in relation to the aterosclerosis appearance.
The natural lactancy, to the chest, is the ideal modality For the growth, also psychological, of the boy
