What bread has the most fiber?

Of the sliced breads we checked against their current labels in October 2026, Carbonaut Gluten Free White Bread lists the most: 15 grams of fiber per 34-gram slice, mostly from resistant tapioca or potato starch, psyllium and inulin. Hero Seeded Bread lists 12 grams, and Nature’s Own Life Keto Soft White 10.

Is Ezekiel bread high in fiber?

Food for Life’s Ezekiel 4:9 Sprouted Whole Grain Bread lists 3 grams of fiber per 34-gram slice. That makes it a “good source” of fiber under FDA rules rather than “high” in fiber, which takes about 5.6 grams. Its fiber comes from sprouted grains and legumes, with no added fiber.

Why is keto bread so high in fiber?

Because most of its flour is replaced with a starch or fiber that resists digestion, such as resistant or modified wheat starch, along with oat fiber or inulin. These count as dietary fiber on the label, which is how a 28-gram slice can list 9 or 10 grams of fiber and 30 to 40 calories.

What counts as “high fiber” on a label?

Under FDA rules, a label can call a food “high” in fiber, or an “excellent source,” when a standard serving has 20 percent or more of the Daily Value, about 5.6 grams.

How much fiber should you eat a day?

The Daily Value on US labels is 28 grams of fiber, for a 2,000-calorie diet, according to the FDA. Most adults eat far less: about 16 grams a day on average, according to USDA’s What We Eat in America survey.

Is added fiber as good as the fiber in whole grains?

Both count on the label, and the FDA counts an added fiber only after accepting evidence that it has a health benefit. They are not identical, though: some added fibers, like chicory root fiber (inulin), ferment quickly, and in studies of healthy adults larger doses caused gas in many people.

The Fiber Rankings

The Highest-Fiber Breads, Ranked

Labels use different servings, one slice or two, so we ranked every bread per slice. We started from every bread filed with the USDA, added the big sellers the file misses and checked each one against its current label.

The top of this list is a new kind of bread. Every loaf at 8 grams a slice or more gets most of its fiber from an added starch or fiber built to resist digestion: resistant or modified wheat starch, resistant tapioca or potato starch, oat fiber, inulin. Most of them are sold as keto or low-carb bread. Carbonaut’s gluten-free white leads at 15 grams in a 34-gram slice, and Hero’s seeded bread lists 12.

Breads built on whole grains and seeds land lower. Silver Hills’ The Big 16 and Trader Joe’s European Grains & Seeds both list 4 grams a slice, and Ezekiel 4:9, often called the high-fiber loaf, lists 3.

Slices differ a lot in size, from 23.5 grams to 60, so each row shows the weight: Mestemacher’s 7 grams come in a 60-gram slice, Carbonaut’s 15 in 34 grams.

Where the fiber comes from

On a Nutrition Facts label, “dietary fiber” adds up two kinds of fiber. One is fiber that is, in the FDA’s words, “intrinsic and intact” in plants: the bran on a wheat kernel, the hull of a flaxseed, whole oats. The other is fiber that has been isolated or made and then added, such as chicory root fiber (inulin), soluble corn fiber, oat fiber or polydextrose. The FDA counts an added fiber only once it has accepted evidence of a benefit, such as lower blood glucose or cholesterol or more frequent bowel movements.

Both kinds count the same toward the number on this page, but they do not always behave the same. Some added fibers ferment fast: in a study of healthy adults, 10 grams of oligofructose, a short-chain form of inulin, noticeably increased gas and other symptoms, and at 20 grams a day of short-chain FOS, six of the eight people in a small Paris study reported excess gas. That is why each product here is tagged “Whole-food fiber” or “Added fiber.” The tag is not a verdict on either kind; it tells you what the number is made of.

All but two of the 20 breads here add an isolated fiber or a resistant starch; the exceptions are Silver Hills’ The Big 16 and Trader Joe’s European Grains & Seeds.

How we built this ranking

We started from all 205 sliced breads in USDA’s FoodData Central Branded Foods database (the April 30, 2026 release), the labels manufacturers and retailers file with the government. We removed impossible records, grouped flavors of the same product (134 product lines) and took the top 30 by fiber on the filed label.

Those records are often years old, and 15 of the top products had been discontinued or could not be found on sale. So we also checked 43 widely sold products in the same aisle that the government file misses or lists under old names. Every product was then checked on October 11, 2026 against the nutrition label its brand, or a major retailer, shows today, and the 20 here are ranked by that current label. Nothing is filled in from memory or from an old record. Regional supermarket store brands (7 records) are left out because most readers cannot buy them; many are close copies of the national products here.

Ranked by grams of dietary fiber per slice, as printed. Serving sizes differ between brands, so each row shows the serving. Labels change: if a package in front of you says something different, the package wins, and we would like to hear about it at editor@guthealthtimes.org.
