Enzyme is a kind of special protein with catalytic ability produced by organism itself. It maintains life and cell activity and is an important part of cells. Where there is life, there are enzymes. Without enzymes, there would be no life. Enzymes not only help the human body to digest and absorb, but also have the functions of metabolism, anti-inflammation, detoxification, activation and repair of cells, degrade the discomfort during drug treatment and the side effects of drugs on the human body, improve immunity and self-healing ability, adjust the balance of all aspects of the human body, and achieve the best health state. Practice has proved that eating a lot of fresh organic vegetables, sprouts and fruits raw can achieve the purpose of supplementing enzymes, improving health and prolonging life. Because the enzyme will be destroyed when the food is heated above 40℃, try to eat organic vegetables and fruits raw. For example, Japan has become the longest-lived country in the world, and a very important factor is the eating habits of Japanese people. Eating fresh vegetables and fruits raw can produce enzymes. The intake of foreign enzymes by human body can save the consumption of prototype enzymes in human body. The greater the amount of protoenzyme stored in human body, the healthier and longer people will live.
