How much fiber is in brown rice?
Brown Rice has 1.6 g of fiber per 1/2 cup cooked (98 g). That is 6% of the 28 g daily value and a moderate amount for a grain. Per 100 g it works out to 1.6 g, which ranks 32 of 41 grains in the FiberUp database. About 13% of that fiber is soluble and 87% insoluble. It would take 16 servings to reach the 25 g adequate intake for women and 24 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.
About brown rice and fiber
A half cup of cooked brown rice provides 1.6 grams of fiber, which is modest but five times what white rice offers. The bran layer is where the fiber lives.
