La leche es un líquido secretado blanco que contiene nutrientes producidos por las glándulas mamarias de hembras de los mamíferos. Contiene casi todos los nutrientes necesarios para mantener la vida.[1] Es la principal fuente de nutrición para los mamíferos desde los primeros días de su vida hasta que son capaces de digerir otros tipos de alimento. Uno de los ingredientes más importantes en la leche es el calcio, responsable del crecimiento de fuertes huesos y dientes.[2]
The milk also has a role in immunity. Substances present in human milk are able to kill intestinal protozoa such as Giardia lambia and, in addition, has the function of protecting infants against this and other infections.[3] Breast milk contains immunological substances that confer passive immunity for the child, such as IgA, lactoferrin, lysozyme, macrophages and other antibodies.[4]
The milk in its natural state contains approximately 87% water, 3.5% of fat, 3.6% protein, 4.9% carbohydrates (lactose) and minerals like calcium and phosphorus. The amount of water is reduced to approximately 4% when in the form of milk powder.[5] Milk is also a source of vitamins C (human milk 3.8 mg/100ml and cow milk 1.5 mg/100ml) and D (human milk 0.8 μg/100ml and cow milk 0.15 μg/100ml).[6] Lactose is a disaccharide found naturally only in milk and its derivatives and it is composed of galactose linked by a β 1-4 glycosidic bond to glucose.[7]
