You found a paleo muffin recipe that calls for coconut flour, you only have almond flour, and the internet says “never swap them one for one.” That warning is right, and the reason is in the numbers. This paleo flour guide compares the six grain-free flours paleo cooks actually use, using USDA laboratory data, explains why each behaves the way it does in a bowl, and gives you a decision table and a blend you can keep in the pantry.
The quick version: The main paleo flours are almond, coconut, cassava, tapioca, arrowroot and chestnut. Almond flour is high-fat and low-carb (16 g carbs per 100 g). Coconut flour is about one-third fiber and very absorbent. Cassava, tapioca and arrowroot are starchy (87–89 g carbs per 100 g), more than wheat flour. Most paleo baking blends a nut flour with a starch.
Which flours count as paleo?
A paleo flour is ground from a nut, seed, root or tuber instead of a cereal grain or legume. Paleo excludes wheat, oats, rice, corn and bean flours because it excludes grains and legumes; the core rules are summarized by Harvard’s Nutrition Source. The six that show up in most paleo recipes:
- Almond flour: finely ground blanched almonds. Rich, moist, low in carbs.
- Coconut flour: dried, defatted coconut meat ground fine. Very high in fiber and very thirsty.
- Cassava flour: the whole cassava (yuca) root, dried and ground. The closest paleo flour to wheat in handling.
- Tapioca flour or starch: the extracted starch of the cassava root. Adds chew and stretch.
- Arrowroot flour: starch from arrowroot rhizomes. A neutral thickener and binder.
- Chestnut flour: ground dried chestnuts. Sweet, nutty and starchier than other nut flours.

How do paleo flours compare nutritionally?
The differences are large enough to change how a recipe turns out and how filling it is. All values come from USDA FoodData Central; almond, coconut, cassava and chestnut flours come from USDA’s newer Foundation Foods laboratory analyses.
| Flour | FDC ID | Calories | Protein (g) | Fat (g) | Carbs (g) | Fiber (g) | Net carbs (g) |
|---|---|---|---|---|---|---|---|
| Almond flour | 2261420 | 622 | 26.2 | 50.2 | 16.2 | 9.3 | 6.9 |
| Coconut flour | 2515382 | 438 | 16.1 | 15.3 | 58.9 | 34.2 | 24.7 |
| Chestnut flour | 2515377 | 385 | 5.3 | 4.6 | 80.5 | 8.7 | 71.8 |
| Cassava flour | 2512377 | 357 | 0.9 | 0.5 | 87.3 | 4.8 | 82.5 |
| Arrowroot flour | 170684 | 357 | 0.3 | 0.1 | 88.2 | 3.4 | 84.8 |
| Tapioca (pearl, dry) | 169717 | 358 | 0.2 | 0.0 | 88.7 | 0.9 | 87.8 |
| Wheat flour, all-purpose (not paleo; reference) | 790018 | 362 | 12.0 | 1.7 | 74.6 | 3.0 | 71.6 |
Per 100 g. Net carbs = total carbohydrate minus fiber, calculated here. Tapioca uses USDA’s dry pearl tapioca entry, the closest SR Legacy match for tapioca flour. Calories for Foundation entries use USDA’s Atwater general factors.
Three findings stand out:
- “Paleo” doesn’t mean low-carb. Cassava, arrowroot and tapioca carry 87–89 g of carbohydrate per 100 g, more than wheat flour’s 74.6 g. Use them for texture, not to cut carbs. If carbs matter to you, see how many carbs to eat on paleo.
- Almond flour is mostly fat. At 622 calories per 100 g, it is about 70% more calorie-dense than wheat flour. Harvard notes almonds are a source of vitamin E, monounsaturated fat, fiber and magnesium (Harvard T.H. Chan, Almonds), so the calories come with nutrients, but portions still matter.
- Coconut flour is a third fiber. Its 34.2 g of fiber per 100 g is more than the entire 28 g Daily Value (FDA). That fiber helps explain why coconut flour soaks up so much liquid.
What does a typical baking portion look like?
Per-100-gram numbers are useful for comparing, but a recipe serving uses far less. Here is the same data for 30 g, roughly the flour in one muffin or a couple of pancakes.
| Flour (30 g) | Calories | Carbs (g) | Fiber (g) | Protein (g) |
|---|---|---|---|---|
| Almond flour | 187 | 4.9 | 2.8 | 7.9 |
| Coconut flour | 131 | 17.7 | 10.3 | 4.8 |
| Chestnut flour | 116 | 24.1 | 2.6 | 1.6 |
| Cassava flour | 107 | 26.2 | 1.4 | 0.3 |
| Arrowroot flour | 107 | 26.4 | 1.0 | 0.1 |
| Tapioca | 107 | 26.6 | 0.3 | 0.1 |
| Wheat flour, all-purpose (reference) | 109 | 22.4 | 0.9 | 3.6 |
Calculated from the USDA per-100 g values above × 0.3.
Can you substitute almond flour for coconut flour?
Not one for one. Almond flour is about half fat with modest fiber; coconut flour is lower in fat and extremely high in fiber, so it absorbs far more liquid. A recipe written for coconut flour uses much less flour and more eggs or liquid. Swapping in the same weight of almond flour gives a wet, flat result; swapping the other way gives a dry, crumbly one.
If you must swap, change the whole recipe rather than one ingredient: find a tested recipe written for the flour you have. When you experiment, change one variable at a time and write down what you did.
Which paleo flour should you use for which job?
Match the flour to the job its composition suits. Protein and fat give structure and moisture; starch gives chew, crispness and binding; fiber gives absorbency.
| Job | Best choice | Why (from the composition) | Watch out for |
|---|---|---|---|
| Cookies, muffins, quick breads | Almond flour, often with a little tapioca | High fat keeps crumb tender; starch adds hold | Browns fast; lower the oven or tent with foil |
| Pancakes and waffles | Cassava, or almond plus tapioca | Starch gives a familiar, fluffy bite | Cassava batters thicken as they rest |
| Very high-fiber bakes | Coconut flour | 34 g fiber per 100 g absorbs liquid | Needs extra eggs or liquid; tested recipes only |
| Tortillas and flatbreads | Cassava flour | Most wheat-like dough handling | High carb; not a low-carb swap |
| Chewy, stretchy texture (cheese-free “bread” bites) | Tapioca | Nearly pure starch | Gummy if overused |
| Thickening stews and gravies | Arrowroot or tapioca | Neutral starch thickens without flavor | Add as a cold-water slurry near the end |
| Breading for meat or fish | Almond flour or almond plus tapioca | Fat helps browning; starch helps crisping | Burns at very high heat |
| Crepes, sweeter bakes | Chestnut flour | Naturally sweet, starchy | Strong flavor; blend with almond |
For thickening in long-cooked dishes, see the arrowroot tip in our paleo slow cooker recipes. For bakes that put these flours to work, try the paleo bread recipes or paleo brownie recipes.
A grain-free all-purpose blend (with its real nutrition)
Store-bought paleo blends vary, so here is a simple one you can make by weight and adjust.
Everyday paleo flour blend (360 g)
– 200 g blanched almond flour
– 100 g tapioca flour (or arrowroot)
– 60 g coconut flour
Whisk thoroughly and store airtight. Use it in recipes written for a nut-starch blend, such as drop biscuits, muffins and breading. It is not a cup-for-cup replacement for wheat flour in yeast breads or cakes.
| Per 30 g | Calories | Protein (g) | Fat (g) | Carbs (g) | Fiber (g) |
|---|---|---|---|---|---|
| Everyday paleo blend | 155 | 5.2 | 9.1 | 13.0 | 3.3 |
| Wheat flour, all-purpose | 109 | 3.6 | 0.5 | 22.4 | 0.9 |
Calculated from USDA FoodData Central values for FDC IDs 2261420, 169717, 2515382 and 790018, weighted by the blend’s gram amounts.
Compared with wheat flour, the blend has about 40% fewer carbohydrates, over three times the fiber and more protein, but about 40% more calories because of the almond fat. That trade-off is the honest summary of paleo baking: better fiber and fewer refined carbs, not fewer calories.
How should you store paleo flours?
Store nut and coconut flours cold; store starches in the pantry. Almond and coconut flours contain fat that can turn rancid, so keep opened bags airtight in the fridge or freezer and let them come to room temperature before baking. Cassava, tapioca and arrowroot are low in fat and keep well in a cool, dry cupboard. Smell before using: a bitter or paint-like odor in nut flour means it has gone off.
Common paleo flour mistakes
- Swapping almond and coconut flour one for one. Their absorbency is completely different.
- Assuming cassava is low-carb. At 87 g of carbs per 100 g, it is higher than wheat.
- Measuring by cup instead of weight. Paleo flours vary in density; a kitchen scale gives consistent results.
- Using only starch. Tapioca or arrowroot alone turns gummy. Pair with a nut or coconut flour.
- Baking at wheat-flour temperatures without watching. High-fat almond flour browns quickly.
- Ignoring allergies. Almond flour is a tree-nut product; check before serving guests.
Frequently asked questions about paleo flour
What flour is paleo-friendly?
Paleo-friendly flours come from nuts, seeds, roots or tubers rather than grains or legumes. The most common are almond, coconut, cassava, tapioca, arrowroot and chestnut flour. Wheat, oat, rice, corn and chickpea flours are not paleo because they come from grains or legumes, which the diet excludes.
Is almond flour or coconut flour better?
It depends on the job. Almond flour, with 50 g fat and 16 g carbs per 100 g, gives tender, moist bakes and is lower in carbs. Coconut flour, with 34 g fiber per 100 g, is lower in calories per gram and very high in fiber, but it absorbs so much liquid that it needs recipes written specifically for it.
Which paleo flour has the fewest carbs?
Almond flour, at 16.2 g carbohydrate and 6.9 g net carbs per 100 g in USDA data. Coconut flour is next at 24.7 g net carbs. Cassava, arrowroot and tapioca are the highest, at roughly 82–88 g net carbs per 100 g, which is more than all-purpose wheat flour.
Is cassava flour the same as tapioca flour?
No. Cassava flour is the whole dried root, ground, so it keeps a little fiber (4.8 g per 100 g) and behaves more like wheat flour. Tapioca is the extracted starch from the same root, with under 1 g of fiber, and it mainly adds chew and binding rather than structure.
Can I use paleo flour to thicken sauces?
Yes. Arrowroot and tapioca are the best paleo thickeners because they are nearly pure starch with a neutral flavor. Mix a tablespoon with two tablespoons of cold water, stir it into the simmering liquid near the end of cooking, and heat briefly until it thickens.
Your next step: buy two flours, not six
Start with almond flour and one starch (tapioca or arrowroot). Those two cover most paleo baking, breading and thickening. Add coconut or cassava flour when a recipe you want to make specifically calls for it. For recipes across every meal, browse the paleo recipes hub.
