What do studies say about Ballaststoffe Senioren?

The provided context does not contain specific studies on fiber in seniors. In general, evidence supports that adequate fiber intake in older adults promotes digestive health, prevents constipation, and may reduce risk of cardiovascular disease and type 2 diabetes. The German Nutrition Society recommends 30 g daily, but many seniors fall short. Gradual increase and sufficient hydration are important to avoid bloating or discomfort. In certain conditions (e.g., IBS, diverticulitis), fiber type should be tailored. Since the context lacks direct references, the evidence is marked as unclear.
