Cassava flour nutrition sits between the fresh root and refined tapioca starch.
The flour keeps more of the root than starch does, yet it stays mostly carbohydrate.
It carries little protein and a glycemic response that surprises many gluten-free bakers.
My cassava flour is made in batches of about three kilograms in Ntigha, Abia State, using a blender, an oven, and three sieves.
I bake chin-chin and buns with it at home, and a two-kilogram pack stayed in good condition after a full year.
This article sets out what that kind of flour contains, using a peer-reviewed study of quality flour and the Codex standard.
It compares flour with the root and with tapioca, reviews glycemic studies from Nigeria, and explains cyanide limits.
A final section shows who should take care and links each special diet to its own guide.

Cassava Flour Nutrition per 100 Grams
For cassava flour nutrition data, a 2017 study in LWT Food Science and Technology analyzed high-quality cassava flour from 45 cassava genotypes.
| Component | Range per 100 g of flour |
|---|---|
| Moisture | 10.8 to 12.7 g |
| Starch | 67.1 to 82.4 g |
| Sugar | 1.7 to 5.7 g |
| Protein | 0.56 to 1.26 g |
| Ash (minerals) | 0.77 to 1.43 g |
| Amylose share of starch | 15.7 to 22.3 g |
Starch dominates, while protein stays near one gram, so cassava flour supplies energy rather than building material for muscles.
Values vary with variety, root age, and processing, which explains why different websites quote different numbers.
What the Codex Standard Allows
The Codex standard for edible cassava flour caps moisture at 13 percent and ash at 3 percent.
It also limits crude fiber to 2 percent, a narrower laboratory measure than the dietary fiber shown on nutrition labels.
Those limits mean good cassava flour is fine, dry, and clean, rather than coarse and fibrous like garri.
My own drying and triple-sieving routine is described in the guide to high-quality cassava flour.
How Flour Compares With the Root and Tapioca
| Product, per 100 g | Calories | Carbohydrate | Protein | Fiber |
|---|---|---|---|---|
| Raw cassava root | 160 kcal | 38.1 g | 1.36 g | 1.8 g |
| Dry tapioca pearls | 358 kcal | 88.7 g | 0.19 g | 0.9 g |
Both rows come from USDA FoodData Central, for raw cassava and dry pearl tapioca.
Flour falls between them, because drying concentrates the root’s nutrients while sieving removes some fiber.
The fresh root’s wider benefits are covered in the review of cassava root health benefits.
Refined starch, with almost no fiber, is examined separately in the guide to tapioca nutrition.
Glycemic Index of Cassava Flour Foods
Glycemic index measures how fast a food raises blood sugar compared with glucose, which scores 100.
A 2017 study of wheat breads containing 10 to 20 percent cassava flour found glycemic indices of 91 to 94, according to its published abstract.
An IITA study of Nigerian staples recorded eba at 88 to 99 and fufu at 86 to 92.
Pupuru, a fermented cassava meal from Ondo State, scored 86 in a 2021 study listed in the Redeemer’s University repository.
Fermented foods like fufu and pupuru still scored high, so fermentation alone cannot be relied on to lower the response.
Smaller portions, paired with protein, vegetables, or soups rich in fish and leaves, remain the practical approach.
Real Benefits of Cassava Flour
- Gluten-free: cassava contains no wheat, rye, or barley, and FDA labels require under 20 parts per million of gluten.
- Grain-free and nut-free: it suits people avoiding cereals or nut flours, including many on paleo plans.
- Whole-root ingredient: unlike tapioca, it keeps more of the root’s fiber, minerals, and natural sugars.
- Long storage: well-dried flour keeps for months, as my one-year storage test showed.
Practical storage advice appears in the guide to storing cassava flour properly.
Natural resistant starch forms mainly in cooked and cooled roots, as the post on cassava resistant starch explains.
Cyanide and Safety Standards
Codex limits hydrogen cyanide in cassava flour to 10 milligrams per kilogram, as FSANZ records in its cassava review.
Thorough peeling, grating or cubing, and drying all lower cyanide, which is why careful processing matters more than variety alone.
Buyers worried about residues can read the explainer asking does cassava flour contain cyanide.
Heavy metal concerns raised online are examined in the article on cassava flour and lead.
Who Should Take Care
- People managing diabetes: cassava flour foods score high on the glycemic index, so portions and pairings need care.
- Low-carb and keto eaters: the flour is mostly starch, as the post on cassava flour and keto explains.
- People with latex allergy: cassava can cross-react, so watch for itching, swelling, or hives.
- Buyers of unknown brands: choose flour from processors who dry and sieve properly and test for cyanide.
Cassava Flour and Special Diets
- Whole30: allowed in specific uses, as the guide to cassava flour on Whole30 explains.
- Lectin-free plans: how the flour fits is covered in the post asking is cassava flour lectin-free.
- Low-oxalate diets: oxalate levels and portions are examined in the article on cassava flour and oxalate.
- Low-FODMAP diets: reviewed in the post asking is cassava flour low FODMAP.
Conclusion
Cassava flour nutrition is simple: mostly starch, about one gram of protein per 100 grams, and modest minerals.
Codex caps moisture at 13 percent and crude fiber at 2 percent for edible flour.
Breads, eba, fufu, and pupuru all scored high in Nigerian glycemic studies, and fermentation alone did not change that.
The flour is gluten-free, grain-free, and stores for months when properly dried.
Choose well-processed flour, watch portions, and pair each serving with protein and vegetables.

Frequently Asked Questions
Is cassava flour healthier than wheat flour?
It is gluten-free and grain-free, but it contains less protein than wheat flour.
For people without gluten problems, neither is healthier, so portion and overall diet matter most.
What is the glycemic index of cassava flour?
Studies of cassava foods report high values, with breads containing cassava flour at 91 to 94.
Nigerian eba and fufu ranged from 86 to 99 in IITA research.
How much protein is in cassava flour?
Cassava flour held 0.56 to 1.26 grams of protein per 100 grams in a 2017 study.
That is far below the protein in wheat, legume, or nut flours.
Does fermentation lower the glycemic index of cassava flour?
Not reliably, since fermented fufu and pupuru still scored 86 to 92 in Nigerian studies.
Portion size and pairing with protein or vegetables make a bigger practical difference.
