What is Cassava Flour?

Cassava flour is a staple in many African, South American, and Caribbean cuisines. It's derived from the starchy tuberous root of the cassava plant, also known as Manihot esculenta, a root vegetable native to South America. The whole root is peeled, dried, and ground into a fine powder to create cassava flour, which has a mild flavor and a texture very similar to traditional wheat flour.

This flour is a main ingredient in many traditional recipes, such as cassava bread. More recently, it has gained popularity in the United States and other parts of the world for its versatility in baking and cooking.

Why is Cassava Flour Not Low Carb?

Cassava flour is high in carbohydrates, particularly when compared to other alternative flours such as almond flour, coconut flour, or flax meal. For instance, a quarter cup of cassava flour contains approximately 28 grams of carbs, which is relatively high compared to just 6 grams in the same amount of almond flour.

In fact, the nutritional value of cassava flour indicates it contains about 84g of carbohydrates per 100g serving. This carbohydrate content includes around 3.7 grams of dietary fiber. Hence, the net carbs, which are the total carbs minus the grams of fiber, still stand at a high level, making it less ideal for those on a ketogenic diet or a low-carb diet aiming for weight loss.

Nutritional Benefits of Cassava Flour

Despite its high carb content, cassava flour does have several health benefits. It's rich in vitamin C, which is essential for a strong immune system. Moreover, cassava flour is naturally gluten-free, making it a good option for those with celiac disease or gluten intolerance. It's also grain-free, which appeals to those following the Paleo diet, also known as the Paleolithic or Caveman diet.

Moreover, cassava flour has a high fiber content, which can help promote a healthy digestive tract and improve gut health. Dietary fiber also helps control blood sugar levels and can aid in maintaining healthy cholesterol levels and blood pressure. However, keep in mind that while it's high in fiber, the high net carb content may still spike blood sugar levels, particularly in people with diabetes or insulin resistance.

Comparison with Other Low Carb Flours

When it comes to low carb flours, several options are much lower in net carbs compared to cassava flour. These flours are commonly used as replacements in baking recipes for those on ketogenic or low carb diets. Here is a comparative chart of a few popular choices:

Type of FlourCarbohydrates per Quarter Cup
Almond Flour6 grams
Coconut Flour16 grams
Flax Meal8 grams
Pecan Flour4 grams
Lupin Flour12 grams
Sunflower Seed Flour6 grams

Almond Flour

Almond flour is a popular low carb, gluten-free flour alternative made from ground, blanched almonds. It's packed with healthy fats, fiber, protein, and essential nutrients like vitamin E and magnesium.

Coconut Flour

Coconut flour is another low carb option, sourced from dried and ground coconut meat. It's high in fiber, protein, and healthy fats. However, it's a highly absorbent flour, so it requires more eggs or liquid in recipes than other flours.

Flax Meal

Also known as flaxseed meal, flax meal is made from ground flaxseeds. It's a great source of omega-3 fatty acids and fiber. It also serves as a good binding agent in gluten-free recipes, similar to xanthan gum.

Pecan Flour

Pecan flour is made from ground pecans and is a lower carb option. It's rich in healthy fats, fiber, and protein.

Lupin Flour

Lupin flour, made from a type of legume called Lupin beans, is a high-protein, high-fiber, low carb option. It's a good source of essential amino acids and minerals.

Sunflower Seed Flour

Sunflower seed flour is a nut-free, low carb flour alternative made from ground sunflower seeds. It's high in vitamin E and magnesium and is a good source of plant-based protein.

Cassava Flour's Role in Gluten-Free Diets

An increasingly significant portion of the population is finding themselves sensitive to gluten, leading to the popularity of gluten-free diets. This diet is essential for individuals with celiac disease, but it's also pursued by many who experience negative side effects from gluten intake. One of the reasons cassava flour has gained popularity is due to its gluten-free properties, making it an excellent alternative to traditional wheat flour for those adhering to a gluten-free diet.

Cassava flour is a natural fit for gluten-free cooking and baking, offering a similar texture to traditional flour and a neutral taste. Moreover, it's a one-to-one substitute for wheat flour in most recipes, making it a versatile choice for a variety of dishes. From bread and pastries to sauces and gravies, cassava flour offers a simple and tasty solution for gluten-free baking and cooking.

A Grain-Free Alternative: Cassava Flour for the Paleo Community

The Paleo diet, also known as the Paleolithic or Caveman diet, involves eating foods that our ancestors might have consumed during the Paleolithic era. This diet primarily includes whole foods, lean proteins, fruits, vegetables, and excludes grains, making cassava flour an ideal choice for Paleo followers.

As a grain-free flour, cassava fits perfectly into the guidelines of the Paleo diet. Its unique combination of texture and taste has made it a staple for many in the Paleo community, serving as the main ingredient in numerous Paleo-friendly recipes.

The Culinary Uses of Cassava Flour

Cassava flour has an impressive versatility that allows it to be used in a variety of dishes beyond baking. In its native regions of Africa, South America, and the Caribbean, cassava is used to create a multitude of dishes, both sweet and savory.

Cassava flour can be used to make flatbreads, tortillas, and pancakes. It's also great for dredging meat or fish before frying for a gluten-free, grain-free coating. Furthermore, due to its fine texture and absorbency, cassava flour can be used to thicken soups, stews, and sauces without altering the flavor profile of the dish. The possibilities with cassava flour are seemingly endless, making it a worthy addition to any creative kitchen.

Sourcing and Storing Cassava Flour

As cassava flour becomes more popular, it's becoming increasingly available in grocery stores and online. When purchasing, look for brands that source their cassava ethically and process it naturally to preserve its nutrients.

Cassava flour should be stored in a cool, dark place, like a pantry or cabinet. Ensure the container is well-sealed to prevent moisture from entering, as this can cause the flour to clump. Properly stored, cassava flour can last for several months.

Cassava Flour vs. Tapioca Flour

While both cassava flour and tapioca flour come from the same plant, they are not the same thing and should not be used interchangeably. Tapioca is the bleached and extracted starch of the cassava root, resulting in a highly processed, low-fiber product.

On the other hand, cassava flour is made from the whole root, meaning it retains all of the dietary fiber and nutrients. This distinction not only affects their nutritional profiles but also their culinary uses. While cassava flour can replace wheat flour in a one-to-one ratio in many recipes, tapioca flour, often found in gluten-free recipes, is usually used as a thickening agent.

To conclude, while cassava flour might not be the best choice for a low carb diet, it's certainly a versatile and nutrient-dense option for those following a gluten-free or grain-free diet. Its versatility in various recipes makes it a valuable addition to any kitchen. Always remember, moderation is key in any diet, and choosing a variety of foods will help ensure you get a wide range of nutrients.


1. Is cassava flour a good choice for a ketogenic diet?

No, cassava flour is not typically recommended for the ketogenic diet due to its high net carb content. A ketogenic diet requires very small amounts of carbs to keep the body in a state of ketosis, and using cassava flour can easily exceed the daily carb intake limit. Alternatives like almond flour, pecan flour, or sunflower seed flour are more keto-friendly.

2. Can I use cassava flour as a thickening agent like regular flour or tapioca flour?

Yes, cassava flour can be used as a thickening agent in recipes. It can thicken sauces, soups, and gravies similar to how traditional flour or tapioca flour (made from the starchy liquid of the cassava root) would.

3. Is cassava flour a good source of protein?

Cassava flour is not a significant source of protein. It contains about 1.6 grams of protein per quarter cup. Other flours like almond flour or lupin flour are much higher in protein.

4. Is cassava flour safe to consume?

Yes, cassava flour is safe to consume. The process of peeling, washing, and cooking effectively eliminates the naturally occurring toxic compounds found in the raw cassava root.

5. Is cassava flour a good source of dietary fiber?

Yes, cassava flour is a good source of dietary fiber, with around 3.7 grams of fiber per quarter cup.
