MILK! The most controversial product

It is impossible to imagine the history of mankind without milk. The first food that we try in our life left a mark in religion, politics, culture, economics, medicine ... Many myths about the creation of the world go back to milk. The ancient Greeks, for example, believed that the Milky Way appeared when the goddess of femininity hera shed milk during the feeding of Hercules - every drop became the star of our galaxy. The word galaxy itself comes from the Greek yaka - milk.
millennias do not subside disputes around the use of milk by man. Do I need to feed babies with breast milk, and if so, who should feed them - mother or nurse? Which animal is better? Is pasteurization evil or good? How to feed cows and goats? How do hormones, antibiotics and genetically modified cereals affect milk?
