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.

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.

Nobody should get all their fiber from one food. Gut bacteria respond to variety, and the fiber calculator shows a mixed day that reaches your number.

Frequently asked questions

How much fiber is in brown rice?
1/2 cup cooked of brown rice, about 98 grams, contains 1.6 grams of dietary fiber. That is 1.6 grams of fiber per 100 grams and 6% of the 28 gram daily value.
Is brown rice high in fiber?
Not especially. Brown Rice has 1.6 g per serving, which ranks 32 of 41 grains in the FiberUp database. It still counts toward plant diversity, but the fiber in a meal will come from elsewhere.
Is the fiber in brown rice soluble or insoluble?
About 13% of the fiber in brown rice is soluble (0.2 g) and 87% is insoluble (1.4 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.
How many servings of brown rice would reach a daily fiber goal?
It would take about 16 servings to reach 25 g (the adequate intake for adult women) and 24 servings to reach 38 g (adult men). Spreading fiber across several foods is easier and better for gut bacteria diversity.

Values are per typical serving from USDA FoodData Central and standard references, rounded to one decimal. Actual fiber varies with variety, ripeness, and preparation. This is general nutrition information, not medical advice.
