What Is Cassava Flour?

Cassava flour is a grain-free, gluten-free, low glycemic index flour made from the root of the cassava plant (Manihot esculenta). Native to South America, cassava is a tuber crop, like potatoes and yams, extensively cultivated, especially in the tropics. Cassava is a major food staple in many countries and provides the foundation of the diet of over 800 million people. 

Cassava is often referred to as yucca, but that is not correct. Because cassava is called "yuca" in parts of South America, that has confused people into thinking that cassava is the same as the yucca plant (Yucca sp.). The two plants are not remotely similar, as they are from entirely different plant families. Cassava is a member of a flowering plant family, while yucca is a cactus-like succulent. Hence, Cassava root is not yucca root, and vice versa.

Cassava Root, Tapioca, and Cassava Flour

Many people are familiar with cassava root as the source of tapioca. Cassava flour is made from the entire ground root, whereas tapioca is composed of only the starch of the root. Tapioca flour is simply ground tapioca.

Cassava flour is higher in fiber and is more functional than tapioca flour in that it can be used in place of corn, wheat, and other grain flour in most recipes. 

Cassava flour has a mild flavor, light color, and powdery texture, making it an extremely close substitute for wheat flour. It does not tend to overpower the recipe, and some people even say they can hardly even tell the difference between cassava flour from conventional flour in recipes. 

Cassava Flour's Health Benefits

One significant health benefit of cassava flour is that it does not raise blood sugar levels as high as other starches like rice, potatoes, pasta, and bread made from wheat and other grains. 

Much of the starch in cassava flour (and tapioca) is resistant starch. This type of starch does not get digested and absorbed into the body. It is a great prebiotic to feed health-promoting bacteria in the small and large intestines. Not only does that improve digestive health and the intestinal microbiome (collection of gut microbes), but it also is very important in improving blood sugar control and cardiovascular health.

Cassava flour also has 3 grams of fiber per quarter cup (compared to all-purpose wheat flour, which has only 1 gram of fiber per quarter cup). Products made entirely or a high percentage of cassava flour with other flours can be a good choice for people with diabetes if consumed in moderate amounts. Cassava flour has a glycemic index score of 46, making it lower than wheat flour (85) and foods like potatoes (78) and rice (70).

4 Incredible Benefits of Cassava Flour

Cassava flour is often used for people who want to avoid gluten, wheat, or other flour sources. Cassava flour is unique because it is a flour that doesn't tend to trigger most allergies. This includes people with nut allergies and those who cannot use almond or coconut flour. It is also grain-free and easy on the digestive system. As mentioned above, cassava flour supports digestive health. 

Some of the many reasons that make cassava flour such a good substitute for wheat flour include the fact that it's:

• Cassava flour is gluten-free: While flours from gluten-containing grains like wheat and rye contribute to problems such as leaky gut and inflammation, cassava is a completely gluten-free option. This can make it a better choice for families and those with sensitive systems. It can also be important for people with autoimmune triggers to reduce common allergens and food irritants.
• Cassava flour is low in sugar: Cassava flour is lower in sugar and has a much lower glycemic index making it quite helpful if someone has diabetes or is trying to watch their blood sugar. It is very important to know which foods have a low glycemic index. Many types of flour and bread can spike their blood sugar even if they don't contain a lot of sugar. The bottom line is that cassava flour is a low-sugar alternative that can help blood sugar levels stay stable.
• Cassava flour is easy to digest: For those who struggle with irritable bowels or other digestive issues, cassava flour is often greatly appreciated. It is gentle and easy to digest, presenting a non-irritating alternative to flours that tend to aggravate digestive problems. In addition, cassava flour helps to promote healthy gut flora and reduce bacterial imbalances by providing dietary fiber and resistant starch that act as beneficial prebiotics. 
• Cassava flour is allergen and grain-free: Cassava flour is a low-allergen food. As a result, it can be a lifesaver for people with food allergies or sensitivities. 

Cooking With Cassava Flour

Traditionally, cassava flour is most commonly used to make flat cakes that do not rise. However, cassava flour can be used to replace wheat flour in most recipes. For additional health boosts, it is suggested that cassava flour is paired with other nutrient-dense ingredients to give a recipe a power-up. Flax meal and chia seeds are popular for adding supplemental nutrition and fiber to a dish. The color and texture of cassava flour are similar to white potatoes, so it generally produces an attractive mouth-feel and appearance when replacing conventional flour in recipes.
