Coconut Flour Nutrition: What USDA Data Shows for GF Baking
Coconut flour has earned a permanent spot in gluten-free pantries, but its reputation often outpaces a clear understanding of what is actually inside the bag. The USDA FoodData Central database gives us a precise, brand-neutral baseline to work from. What the numbers reveal is a flour with a genuinely unusual nutritional architecture — one that explains why recipes behave so differently when you swap it in for rice flour, almond flour, or any conventional wheat-based product.
The Full Nutritional Picture
The table below presents every nutrient value recorded in the USDA dataset for coconut flour, per 100 g of flour. These are the only figures discussed throughout this article.
| Nutrient | Amount per 100 g | Unit |
|---|---|---|
| Protein | 16.1 | g |
| Total Fat | 15.3 | g |
| Carbohydrate (by difference) | 58.9 | g |
| Fiber, total dietary | 34.2 | g |
| Calcium (Ca) | 36.0 | mg |
| Iron (Fe) | 8.02 | mg |
| Magnesium (Mg) | 248 | mg |
| Potassium (K) | 2090 | mg |
| Sodium (Na) | 46.9 | mg |
| Zinc (Zn) | 3.7 | mg |
The Fiber Story: Why 34.2 g Changes Everything
The single most structurally significant number in that table is the dietary fiber content: 34.2 g per 100 g. That means more than one-third of coconut flour by weight is fiber. To put that in practical baking terms, a flour this dense with fiber behaves almost like a sponge at a molecular level. Fiber particles absorb liquid aggressively and hold onto it throughout mixing, baking, and cooling.
For the gluten-free baker, this creates an immediate and very common problem: dryness and crumbling. Recipes developed for wheat flour or even for rice flour assume a much lower fiber load, so the liquid ratios simply do not translate. Most experienced coconut flour bakers end up using roughly a quarter of the volume they would use with other flours and dramatically increasing eggs or other liquids to compensate. The fiber is not a flaw — it is the defining characteristic of the ingredient — but it demands that you treat coconut flour as its own category rather than a straightforward substitute.
On the positive side for gluten-free eaters, that 34.2 g of fiber contributes real staying power. High-fiber foods tend to slow the digestive process, which supports a more gradual energy release compared with low-fiber flours. In general educational terms, this is one reason coconut flour baked goods are often described as more filling than their counterparts made with starchier flours — a quality that many GF bakers actively seek out.
The Fat Profile: 15.3 g and What It Means for Texture
At 15.3 g of fat per 100 g, coconut flour carries a meaningful fat content relative to most grain-based flours. This fat comes from the dried coconut meat and, while the USDA dataset does not break out fatty acid types within this particular entry, the presence of this level of fat has direct textural consequences.
Fat in baked goods contributes tenderness, moisture retention, and a richer mouthfeel. In coconut flour recipes, the endogenous fat in the flour itself acts as a partial built-in shortening. This is one reason that well-formulated coconut flour muffins or pancakes can achieve a surprisingly tender crumb even when added fat in the recipe is kept modest. It also means the flour has a shorter shelf life than very low-fat alternatives — the fat can go rancid if the flour is stored improperly. A cool, dry pantry or sealed container in the refrigerator is the practical recommendation.
The interplay between that 34.2 g of fiber and 15.3 g of fat is what gives coconut flour baked goods their distinctive dense-but-moist texture when the recipe is balanced correctly, and a dry, crumbly, almost gritty texture when it is not. The fiber pulls in liquid; the fat holds the crumb together. Getting those two forces in equilibrium is the central challenge of coconut flour baking.
Minerals Worth Noting
Coconut flour is not just about fiber and fat. The mineral profile in the USDA data is notably rich, and for gluten-free eaters who may have reduced dietary variety, these numbers are worth understanding.
- Potassium: 2090 mg per 100 g — an exceptionally high figure. Potassium is among the most abundant minerals in coconut flour by this dataset.
- Magnesium: 248 mg per 100 g, a mineral that is frequently under-consumed in Western diets.
- Iron: 8.02 mg per 100 g, meaningful given that iron deficiency is a documented concern in some individuals following a gluten-free diet who have reduced their intake of fortified grain products.
- Zinc: 3.7 mg per 100 g, another mineral that can be harder to source in quantity from a restricted diet.
- Calcium: 36.0 mg per 100 g — present, though modest relative to the other minerals listed.
Because typical recipes use a small volume of coconut flour, the absolute mineral contribution per serving will be lower than these per-100-g values suggest. Still, the density of these nutrients makes coconut flour a more micronutrient-rich choice than many highly refined GF flour alternatives.
About This Data
All figures in this article come from USDA FoodData Central (fdc.nal.usda.gov), the official U.S. government food composition database. The specific entry used is “Flour, coconut,” FDC ID 2515382, with data retrieved on 2026-07-17. It is important to note that nutrient values can vary meaningfully between brands and production batches depending on the variety of coconut used, drying methods, and processing conditions. The USDA values represent a scientifically measured reference point, not a guarantee for every package you purchase.
How to Use This in Your Kitchen
- Start with less flour. Because of the 34.2 g fiber content, coconut flour absorbs dramatically more liquid than other flours. Begin with a proven coconut-flour-specific recipe rather than attempting a direct volume substitution.
- Add more eggs or liquid. The fiber’s water-binding capacity means most successful coconut flour recipes call for a higher ratio of eggs or other liquids to flour than you are used to. This is not a mistake in the recipe — it is a requirement of the fiber profile.
- Let the batter rest. Allowing the batter to sit for a few minutes before baking gives the fiber time to fully hydrate, which produces a more even texture in the finished bake.
- Store carefully. The 15.3 g fat content means the flour can oxidize. Keep it sealed, away from heat and light.
- Expect satiety. The high fiber and fat combination means portions are genuinely filling, which can be helpful for managing appetite throughout the day.
Frequently Asked Questions
Why does my coconut flour bread always turn out dry and dense?
The 34.2 g of dietary fiber per 100 g causes coconut flour to absorb a very large volume of liquid. If you are using a recipe designed for a lower-fiber flour and simply substituting coconut flour, the flour is drawing far more moisture than the recipe accounts for. Use recipes written specifically for coconut flour, or expect to substantially increase your liquid and egg quantities.
Is coconut flour high in carbohydrates?
The total carbohydrate figure is 58.9 g per 100 g by the USDA data. However, of those 58.9 g, 34.2 g is dietary fiber. Fiber is counted within total carbohydrates in standard nutrition labeling but is not digested and absorbed in the same way as sugars and starches. The net digestible carbohydrate content is therefore considerably lower than the headline carbohydrate number suggests.
Does coconut flour provide meaningful protein for a GF diet?
At 16.1 g of protein per 100 g, coconut flour is a comparatively protein-rich flour. For gluten-free bakers looking to increase protein in their baked goods without adding protein powder, this is a genuine advantage over many starch-heavy GF flour blends.
What makes the mineral content of coconut flour stand out?
The potassium content of 2090 mg per 100 g is particularly striking, alongside 248 mg of magnesium and 8.02 mg of iron. These are nutrients that can be harder to obtain in sufficient quantities on a restricted gluten-free diet, making coconut flour a nutritionally denser option than many of its GF counterparts — even accounting for the small quantities typically used per recipe.
