How much fiber is in green beans?
Green Beans have 2.7 g of fiber per 1 cup (110 g). That is 10% of the 28 g daily value and a moderate amount for a vegetable. Per 100 g it works out to 2.5 g, which rank 21 of 60 vegetables in the FiberUp database. About 30% of that fiber is soluble and 70% insoluble. It would take 10 servings to reach the 25 g adequate intake for women and 15 for the 38 g for men. Source: USDA FoodData Central.
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.
