What role does Glukose play in Darmgesundheit?

Glucose is a primary energy source for intestinal cells and gut microbes. In balanced amounts it supports gut barrier function, but excess glucose can promote dysbiosis (e.g., overgrowth of Proteobacteria) and increase intestinal permeability, potentially contributing to low-grade inflammation. Most evidence comes from animal models and in vitro studies; human trials directly linking glucose intake to gut health outcomes are limited and often confounded by overall diet. DNA-based claims (e.g., FADS2 variants) are not clinically actionable for glucose management. The role of glucose in gut health is mechanistically plausible but not robustly proven in humans. A whole-diet approach (fiber, polyphenols) is more evidence-based. Safety note: individuals with diabetes or IBS should monitor glucose intake under medical guidance.
