Breast milk – as the first food for the newborn, whether human or mammal – contains all the essential nutrients that the newborn requires. Breast milk is a whole food in the sense that the baby is fully nourished by it. Its composition changes and is therefore adapted to the needs of the growing infant. Milk is a healthy food both for children and adults, but can trigger intolerances (to lactose) or food allergies. While milk is one of the basic foods in European countries, in Asian countries it is drunk very rarely or not at all. Asians have no lactase, the enzyme required in order to digest milk. In terms of nutrients, besides the easily digestible milk protein, milk provides lactose, valuable B vitamins and vitamin D. It is also an important source of calcium and other minerals. Fresh unprocessed milk, the raw milk, contains enzymes and microorganisms by nature. These help digestion and contribute to developing and maintaining a health gut microbiota. The specific fatty acid composition of the milk is particularly sensitive and is highly dependent on the cows' feed and the way they are kept [1]. Studies show that milk from cows that are kept extensively and eat a lot of grass but only small amounts of concentrates has a higher content of polyunsaturated fatty acids and conjugated linoleic acid compared to milk from cows ...
