How much fiber is in whole wheat bread?

Whole wheat bread delivers 2 grams of dietary fiber in a typical 1 slice serving, which makes it a small amount of fiber. That covers roughly 7% of a 28 gram daily reference intake, so it adds gently toward your fiber goal for the day.

Of that total, about 0.3 g is soluble fiber (which forms a gel in the gut and helps with cholesterol and blood-sugar) and 1.7 g is insoluble fiber (which adds bulk and supports regularity).

USDA FoodData Central; total dietary fiber nutrient 1079. Soluble and insoluble grams are category-based estimates, not lab-measured values.
