sind bananen ballaststoffreich — what symptoms are typical?

Bananas are not exceptionally high in fiber: a medium banana (≈100 g) provides about 2.6 g of fiber, which is modest compared to oat bran (10–15 g/100 g) or legumes (10–15 g/100 g). The DGE recommends 30 g/day. Typical symptoms of insufficient fiber intake include constipation, irregular bowel movements, bloating, and increased risk of diverticulosis. If fiber intake is suddenly increased (e.g., by eating many bananas), flatulence and abdominal cramps can occur due to fermentation of soluble fiber in the colon. The evidence for these symptoms comes from general nutritional observation and intervention studies, not from the provided knowledge base. Therefore, the evidence level is moderate.
