wieviel ballaststoffe hat eine banane — what can you do yourself?

A medium banana (about 100–120 g) contains roughly 2.6–3.1 g of dietary fiber. That's a moderate amount – compare to an apple (~2.4 g) or a serving of oatmeal (40 g, ~4 g). Bananas are a decent but not exceptional fiber source. What you can do yourself: Eat the banana when ripe but not overripe – as it ripens, insoluble fiber partially converts to soluble fiber, which is good for gut flora but slightly reduces total fiber. Pair it with other fiber-rich foods like nuts, seeds, or whole grains to boost your daily intake. The recommended daily fiber intake is 25–30 g (US/Europe), so one banana covers only about 10%. For more fiber, focus on a diverse plant-based diet. Safety note: For sensitive guts or IBS, less ripe bananas (higher resistant starch) may be better tolerated than very ripe ones. These values are based on standard nutrition databases, not a specific study. Evidence: practice-based.
