Frequently asked questions

How much fiber is in rye bread?

1 slice of rye bread, about 32 grams, contains 1.9 grams of dietary fiber. That is 5.9 grams of fiber per 100 grams and 7% of the 28 gram daily value.

Is rye bread high in fiber?

Not especially. Rye Bread has 1.9 g per serving, which ranks 28 of 41 grains in the FiberUp database. It still counts toward plant diversity, but the fiber in a meal will come from elsewhere.

Is the fiber in rye bread soluble or insoluble?

About 32% of the fiber in rye bread is soluble (0.6 g) and 68% is insoluble (1.3 g). Soluble fiber forms a gel that slows digestion and feeds gut bacteria; insoluble fiber adds bulk and speeds transit.

How many servings of rye bread would reach a daily fiber goal?

It would take about 14 servings to reach 25 g (the adequate intake for adult women) and 20 servings to reach 38 g (adult men). Spreading fiber across several foods is easier and better for gut bacteria diversity.

Values are per typical serving from USDA FoodData Central and standard references, rounded to one decimal. Actual fiber varies with variety, ripeness, and preparation. This is general nutrition information, not medical advice.
