Digestive System
Digestion, Absorption & Gastrointestinal Physiology
Digestive System includes the tract and accessory organs processing food, broader than the alimentary tube alone.
Digestion breaks food into smaller absorbable components; absorption moves them across the gastrointestinal barrier into the body. Transport, storage and tissue use follow. These steps are connected but distinct. For an athlete, a large amount printed on a label establishes intake, not necessarily rapid delivery to muscle or the final amount used. Avoid treating digestion, uptake and performance as interchangeable outcomes.
Chewing, mixing and gut movements alter food's exposed surface, while enzymes hydrolyze suitable bonds using water. Physical particle reduction differs from molecular hydrolysis, and nutrients do not all need the same enzymes. Chewing prepares a bolus, but no magical chew count or finer texture guarantees complete symptom-free absorption. Food structure, preparation and the rest of the digestive process still matter.
A digestive enzyme accelerates particular reactions according to bond type, environment and substrate access. One enzyme cannot necessarily break every food component. Some are made as precursors and activated later to limit inappropriate injury. Separate normal physiology from supplement effects: an enzyme's presence in the body does not itself prove that additional intake improves digestion or sports performance in someone without a relevant deficiency.
For example, record amount, food form and time before training when assessing a meal; neither a label value nor one blood peak alone establishes complete absorption and use.
