Tips and advice on choosing milk

Of course, the most useful is the fresh milk.But not everyone can afford to buy it.When purchasing a product in markets or in stores, follow the rules described below.

  • When buying village milk, you need to be sure of the cleanliness of both the animal and its owner.
  • In the store choose a pasteurized( not sterilized!) Product, because the first has a more gentle treatment, which allows you to save all the useful properties to the maximum.
  • Never buy a product called "milk drink".From real milk there is nothing.It is made from dry mixes, so no such product will bring any benefit.
