How much fiber is in banana?
Banana has 3.1 g of fiber per 1 medium (118 g). That is 11% of the daily value and a good amount for a fruit.
Soluble vs insoluble
The split is approximate and comes from USDA SR Legacy analyses where available. Soluble fiber dissolves into a gel and is the type most linked to cholesterol and blood sugar effects. Insoluble fiber adds bulk and keeps things moving.
