Throughout the system in a healthy individual, enzymes and all the nutritional substances from vitamins to amino acids etc. work together in a collaborative manner in order to promote and maintain a healthy body. Since the various nutritional substances synergistically work together, a weakness in one group of substances tends to interfere in the efficiency of other substances throughout the system. A deficiency in a specific enzyme can cause poor performance by other nutrients, which are dependant on the enzyme. Metabolic enzymes play a key role in running bodily processes. They also repair damage and decay as well as heal tissues.
Digestive enzymes serve to assimilate carbohydrates, proteins and fats in the body.
Raw food enzymes begin the process of food digestion and aid the body's digestive enzymes. There of four categories of plant enzymes , one of which is cellulase. Plant food is a persons' only source for cellulase, as the body cannot produce it. Cooking food can and often does destroy important plant enzymes. They are quite sensitive to heat and are the first nutrients to be destroyed during cooking.
