How much fiber is in sweet potato?

Sweet Potato delivers 4.5 grams of dietary fiber in a typical 1 medium serving, which makes it a moderate source of fiber. That covers roughly 16% of a 28 gram daily reference intake, so it adds gently toward your fiber goal for the day.

Of that total, about 1.3 g is soluble fiber (which forms a gel in the gut and helps with cholesterol and blood-sugar) and 3.2 g is insoluble fiber (which adds bulk and supports regularity).

USDA FoodData Central FNDDS 2021-2023; FDC ID 2709697; total dietary fiber nutrient 1079. Total fiber is from USDA FNDDS; soluble and insoluble grams are category-based estimates, not lab-measured values.
