Finally, thanks to the advance of technology, scientists have concluded that most people succumb to disease and illness due to weakened immune systems.
Enzymes are responsible for the functions of every organ.
The body is a big efficient chemical factory and enzymes are needed for every chemical action and reaction. Every gene's program is associated with the actions of enzymes. Even vitamins and nutrients can't be used effectively without enzymes. The immune system's function is to fight off all foreign invaders in the body such as bacteria, viruses, carcinogens and other chemicals. It relies almost totally on enzymes to do its job.
