What is cold-pressed oil? What is refined oil?
Basically, the oil have two ways to be produced. One is physical pressing method, one is using the chemical leaching method.The chemical leaching method utilizes various chemical refining processes and is refined at a high temperature. The advantage is that the oil yield is high. But the high temperatures in it destroy nutrients and may leave chemicals that are harmful to humans. Although the physical pressing method has a low oil yield, the physical method does not leave harmful chemicals and maintains most of the nutrients.
