Sweet potato delivers 3.8 grams of dietary fiber in a typical 1 medium baked 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, an estimated 0.8 g is soluble fiber (which forms a gel in the gut and helps with cholesterol and blood-sugar) and an estimated 3 g is insoluble fiber (which adds bulk and supports regularity).
