Overview
About Cassava Flour
Cassava flour is the whole cassava root peeled, dried and milled, and that whole root origin is the entire point of it.
Tapioca starch comes from the same plant but is only the starch washed out of the root, so it arrives as pure carbohydrate, while cassava flour keeps the fibre and the rest of the root with it. On the trigger panel the flour is close to spotless: A for gluten, histamine, histamine liberation, salicylate, oxalate, nickel, sulfite, glutamate, dairy protein and nightshade. Its single borderline grade is fermentability at C, and that is precisely the retained fibre doing what fibre does in a gut that ferments too eagerly. The commercial drying and milling process also deals with the cyanogenic compounds that make the raw root dangerous, so the flour on a supermarket shelf does not carry the preparation risk fresh cassava does.

How Cassava Flour scores
Watch for
What trips people up
- It is not interchangeable with tapioca flour. Cassava flour is the whole dried root and tapioca is the extracted starch, so they absorb liquid differently, bake differently and land differently in the gut. Substituting one for the other cup for cup is the most common reason a recipe fails.
- Borderline at C for low fermentation and SIBO. The fibre that makes it more nourishing than pure starch is also what ferments, so it can bloat where tapioca starch or arrowroot pass quietly.
- FODMAP content is unrated for the flour in our data while the fresh root grades B. Treat a heavy cassava flour bake as an unmeasured portion rather than a confirmed green light.
- Grain free does not mean allergen free. Cassava flour grades A for gluten, but shared mills and shared bakery lines still matter if you are coeliac, so buy certified if that applies to you.
- Food grade cassava flour is processed to strip the root cyanogens. The exception is under-processed flour milled from bitter cassava in subsistence settings, which has been behind poisoning outbreaks and is a processing failure rather than a property of the flour you buy.

FAQ
Common questions about Cassava Flour
Is cassava flour the same as tapioca flour?
No, although they come from the same root and the names are used carelessly. Tapioca flour and tapioca starch are the same product: the starch extracted and washed out of cassava. Cassava flour is the whole peeled root dried and ground, so it contains the fibre too. Cassava flour is heavier, more absorbent and more filling, and swapping them one for one in a recipe rarely works.
Is cassava flour low FODMAP?
Our data leaves FODMAP content unrated for the flour, while the fresh root grades B for total FODMAPs and A for every individual FODMAP group. In practice that means a small quantity is usually fine and a dense cassava flour loaf is an unknown quantity worth testing against your own log rather than assuming.
Does cassava flour contain gluten?
No. It is milled from a root, so there is no gluten in it at all and it grades A on the gluten column. The only caveat for coeliac disease is cross contact during milling and packing, which is a facility question rather than an ingredient one.
Is cassava flour safe given raw cassava contains cyanide?
Commercially produced cassava flour is safe. The peeling, soaking or fermenting and drying that turn the root into flour are the same steps that break down its cyanogenic glycosides. The documented poisonings come from bitter cassava processed too quickly in subsistence conditions, not from the packaged baking flour sold in shops.
