Researchers in Japan clarified the mechanisms of action in a type of isothiocyanate found in papaya known as BITC, that underlies the relationship between cell cycle regulation and appropriate cell death. When cancerous cells die on schedule, they are no longer a problem. The researchers established that BITC exerted cancer cell killing effects that were greater in the proliferating cells than in the quiescent cells. Cancer cells that are proliferating are much more dangerous than cancer cells that are in a state of dormancy. (Forum of Nutrition, 2009)
Enzymes from papaya digest proteins including those that protect tumors
Research has shown that the physical and mental health of people is highly dependent on their ability to produce proteins they can use effectively. However, as people age, they produce less of the enzymes needed to effectively digest proteins from food and free needed amino acids. They are left with excessive amounts of undigested protein which can lead to overgrowth of unwanted bacteria in the intestinal tract, and a lack of available amino acids.
Eating papaya after a meal promotes digestion, and helps prevent bloating, gas production, and indigestion. It is quite helpful after antibiotic use to replenish friendly intestinal bacteria that were the casualties in the war against the unwanted bacteria. When the intestinal tract is well populated with friendly bacteria, the immune system is strengthened, and can better protect against flu and cancer.
Being a proteolytic enzyme, papain is able to destroy intestinal parasites, which are composed mostly of protein. To rid the body of intestinal parasites, half a cup of papaya juice can be alternated each hour for twelve consecutive hours with the same amount of cucumber or green bean juice.
Papaya contains fibrin, another useful compound not readily found in the plant kingdom. Fibrin reduces the risk of blood clots and improves the quality of blood cells, optimizing the ability of blood to flow through the circulatory system. Fibrin is also important in preventing strokes. Proteolytic enzymes containing fibrin are a good idea for long plane rides to minimize the potential of blood clots in the legs. People who sit at a desk all day might want to use proteolytic enzymes too.
Proteolytic enzymes are able to digest and destroy the defense shields of viruses, tumors, allergens, yeasts, and various forms of fungus. Once the shield is destroyed, tumors and invading organisms are extremely vulnerable and easily taken care of by the immune system.
Undigested proteins can penetrate the gut and wind up in the bloodstream where they are treated by the immune system as invaders. If too many undigested proteins are floating around, the immune system becomes overburdened and unable to attend to the other tasks it was meant to do. Proteolytic enzymes can digest these rogue proteins, freeing up the immune system
