The present invention provides a method and products for establishing nutrient recognition and improving nutrient utilization and growth in a human or an animal by immunologically stimulating digestion or a gastric cascade within the gastrointestinal tract, by orally or parenterally immunizing the human or animal with an immunizing effective amount of an ingestible antigen or a mixture of ingestible antigens and orally reintroducing the antigen(s). Another aspect of the invention provides a method and products for preventing and treating gastrointestinal disease by immunologically stimulating a gastric cascade, namely, blood flow, production of mucus and release of digestion regulatory factors within the gastrointestinal tract of a human or an animal, by orally or parenterally immunizing the human or the animal with an immunizing effective amount of an ingestible antigen or a mixture of ingestible antigens and orally reintroducing the antigen(s). More generally, the invention provides a process, as well as products, for stimulating a gastric cascade in an animal or human. The gastric cascade is useful for preventing or treating gastrointestinal disorders, including ulcers, as well as for improving nutrient utilization, growth and/or resistance; the latter being inclusive within the term "gastrointestinal treatment".
