Cornmeal is a pantry staple in cornbread, polenta, tortillas, and crispy coatings — but its fiber content changes dramatically depending on how the corn is milled. This Cornmeal Fiber Per 100g Calculator shows exactly how much dietary fiber is in whole-grain, bolted, degermed, and self-rising cornmeal, scaled from a standard 100-gram reference to whatever amount your recipe calls for.
Choose the cornmeal type that matches the bag in your kitchen, enter your portion in grams or ounces (or tap a quick-fill preset like 1 cup or 1 tablespoon), and the calculator returns fiber per 100 g, total fiber in your serving, and the percentage of the daily fiber value based on the 28 g FDA reference. It is a practical companion for meal planning, macronutrient tracking, and anyone comparing stone-ground cornmeal with refined supermarket corn products.

How This Calculator Works
Cornmeal fiber values come from the USDA FoodData Central nutrient database, which reports dietary fiber per 100 grams of dry cornmeal. The calculator applies a simple proportion: total fiber = (fiber per 100 g ÷ 100) × serving weight in grams. If you enter ounces, it first converts to grams using the standard factor 1 oz = 28.3495 g. The % Daily Value uses the FDA reference of 28 g of fiber per 2,000-calorie diet. Because cornmeal is dry, these numbers apply to uncooked cornmeal; once you make cornbread or polenta, water dilutes fiber per cooked weight, so the fiber per 100 g of cooked product will be lower.
Whole-grain stone-ground cornmeal retains the bran and germ, so it provides about 7.3 g of fiber per 100 g — nearly double the fiber of degermed cornmeal, which has most of the bran removed to extend shelf life.
Reference Fiber Values
The values below are typical figures for dry cornmeal as listed in common USDA entries. Exact numbers vary slightly by brand and grind, so check the nutrition label when precision matters.
| Cornmeal type | Fiber per 100 g |
|---|---|
| Whole-grain (stone-ground) | 7.3 g |
| Bolted (partially sifted) | 4.0 g |
| Degermed, enriched | 3.9 g |
| Self-rising (degermed) | 3.9 g |
Worked Examples
Example 1 — Whole-grain cornbread batter: A recipe calls for 122 g (about 1 cup) of whole-grain cornmeal. Total fiber = 7.3 g ÷ 100 × 122 g = 8.9 g. That serving provides 8.9 ÷ 28 × 100 = 32% of the daily fiber value.
Example 2 — Degermed cornmeal coating: You use 45 g (about 3 tablespoons) of degermed cornmeal for oven-fried chicken. Total fiber = 3.9 g ÷ 100 × 45 g = 1.8 g, or 6% DV. The same weight of whole-grain cornmeal would give 3.3 g, a noticeable difference if you are tracking fiber.
Tips & Common Mistakes
- Weigh cornmeal with a kitchen scale instead of measuring cups; cup volumes can vary by 20% depending on scooping, sifting, and grind size.
- Plain cornmeal without the words whole-grain or stone-ground on the package is almost always degermed, so expect the lower fiber value.
- Do not confuse cornmeal with masa harina. Masa is made from nixtamalized corn (soaked in lime water) and has a different nutrient profile and fiber content.
- Remember that the calculator reports fiber for dry cornmeal only. If you mix cornmeal with flour, milk, eggs, or other ingredients, the fiber per 100 g of the final batter or baked good will be lower.
For medical or therapeutic meal planning, consult a registered dietitian. Individual fiber needs vary, and the 28 g reference is a general guideline, not a personal target.
Frequently Asked Questions
Why does whole-grain cornmeal have more fiber than degermed? Whole-grain cornmeal keeps the bran and germ during milling; degermed cornmeal removes them to extend shelf life, which also removes most of the fiber and several vitamins. Enrichment adds back some B vitamins and iron, but not fiber.
Is cornmeal gluten-free? Pure cornmeal is naturally gluten-free. However, if you have celiac disease, look for a package that explicitly says gluten-free, because some facilities process cornmeal on shared equipment with wheat.
How does fiber in cornmeal compare with oats or wheat flour? Whole-grain wheat flour has about 12 g of fiber per 100 g, rolled oats about 10 g, and brown rice flour about 4.5 g. Stone-ground cornmeal at 7.3 g sits in the middle, making it a reasonable whole-grain choice for gluten-free baking.
Can I use this calculator for corn flour or grits? The values apply to dry cornmeal. Corn flour is more finely ground and may be milled from the whole kernel or degermed corn; grits are coarser and often degermed. Check the individual product label or a specific USDA entry for those foods.
