The human breast milk, an inexhaustible source of health and well-being
1 litre of milk of woman makes an average of 670 kcal (2 720 kJ), it is said that cow's milk.
The main sugar of milk of woman is lactose which, thanks to the lactase enzyme present in the intestinal cells, is split into glucose and galactose. The galactose enters the composition of cérébrosides n é cessaires the synthesis of myelin. . Cow's milk contains less lactose than milk.
The milk of woman also includes many oligosaccharides which only some are known at this time.
Their role is still misunderstood but it is likely to encourage the development of an intestinal microbial flora (lactobacillus bifidus) prot ge è the intestinal mucosa against bacterial attack.
If the wealth of both fat milk (cow and woman) is substantially identical, it is not the same for the proportion of unsaturated fatty acids. A liter of milk of woman makes two to nine times more unsaturated fatty acids (linoleic acid and arachidonic) a litre of milk (cow) industrial semi-skimmed milk. These fatty acids are essential for the synthesis brain and the human body is not known to produce them.
In addition, cow's milk makes two times less iron than breast milk of women.
The levels of both zinc milk (woman and cow) are identical, but this metal is present in human milk in a specific form which explains the exclusive role of milk woman in the prevention and treatment of acrodermatitis enteropathica (hereditary disease resulting from a deficiency in zinc and whose manifestations are mainly gastrointestinal and skin).
Compared to cow's milk, the levels of vitamins are at higher rates in breast milk. "
