What should I know about verdauung von eiweiss?

Protein digestion is a multi-step process. It starts in the stomach, where gastric acid denatures proteins and pepsin begins cleavage. In the small intestine, pancreatic enzymes (trypsin, chymotrypsin, elastase, carboxypeptidases) break proteins into smaller peptides and amino acids. Brush border enzymes on intestinal cells then split peptides into individual amino acids for absorption. Efficiency depends on stomach acid production, pancreatic function, gut health, and age. Some direct-to-consumer DNA tests claim to identify genetic variants affecting digestive enzymes, but the evidence is mostly weak and mechanistic. A healthy person with a balanced diet typically absorbs sufficient amino acids. Persistent symptoms like bloating or fullness after protein-rich meals warrant a medical check for enzyme insufficiency or other conditions. Supplements like betaine HCl or digestive enzymes are only justified in specific cases and not recommended for healthy individuals.
