How much fiber is in oat milk?

Oat Milk delivers 1.2 grams of dietary fiber in a typical 1 cup serving, which makes it a small amount of fiber. That covers roughly 4% of a 28 gram daily reference intake, so it adds gently toward your fiber goal for the day.

Of that total, about 0.2 g is soluble fiber (which forms a gel in the gut and helps with cholesterol and blood-sugar) and 1 g is insoluble fiber (which adds bulk and supports regularity).

USDA FoodData Central FNDDS 2021-2023; FDC ID 2705412; total dietary fiber nutrient 1079. Total fiber is from USDA FNDDS; soluble and insoluble grams are category-based estimates, not lab-measured values.
