How much fiber is in rolled oats?

Rolled oats delivers 4 grams of dietary fiber in a typical 1 cup cooked serving, which makes it a moderate source of fiber. That covers roughly 14% of a 28 gram daily reference intake, so it adds gently toward your fiber goal for the day.

Of that total, about 1.6 g is soluble fiber (which forms a gel in the gut and helps with cholesterol and blood-sugar) and 2.4 g is insoluble fiber (which adds bulk and supports regularity).
