Cassava Flour: Friend Or Foe On Keto?

Cassava flour is a popular gluten-free alternative to wheat flour, but is it allowed on the keto diet? The keto diet is a low-carbohydrate method of eating, so the high carbohydrate content of cassava flour means it is not considered keto-friendly. Cassava flour is made from the root and tuber of the cassava plant, and while it is a good source of dietary fibre, potassium, magnesium and vitamin C, it is not recommended for the keto diet due to its high net carb content. One cup of cassava flour contains around 100-110 grams of net carbs, which can quickly exceed the recommended daily net carb intake and disrupt ketosis.

Cassava flour is high in net carbs

Cassava flour is made from the root and tuber of the cassava plant, which is native to the lowland rainforests of South America. It is a popular gluten-free alternative to wheat flour and is used to make bread, cakes, pastries, and more. However, it is important to note that cassava flour is high in net carbs, which can impact ketosis.

The keto diet, or the ketogenic diet, is a low-carbohydrate method of eating. On this diet, the body enters a state of ketosis, where it burns fat for energy instead of carbohydrates. To maintain ketosis, it is crucial to limit the daily net carb intake to 20 to 50 grams.

Cassava flour has a high net carb content, which can quickly exceed the daily limit for those on the keto diet. According to the U.S. Department of Agriculture (USDA), one cup (128 grams) of cassava flour contains around 100 grams of net carbs. This is even higher than the net carb content of regular white wheat flour, which has 92 grams of net carbs per cup.

The high carb content of cassava flour can cause blood sugar spikes and contribute to weight gain, insulin resistance, and diabetes. Additionally, cassava flour has a high glycemic index (GI) of 94, which is a measure of how quickly a food raises blood sugar and insulin levels. This is much higher than the GI of table sugar, which is 65. As a result, cassava flour can disrupt ketosis and block the body's ability to burn fat as an energy source.

In conclusion, while cassava flour is a popular gluten-free alternative to wheat flour, it is not suitable for the keto diet due to its high net carb content. It is important for those following the keto diet to be mindful of the carb content of the foods they consume and choose alternatives with lower carb counts.

It can cause blood sugar spikes

Cassava flour is not keto-friendly as it can cause blood sugar spikes. It is made from the root and tuber of the cassava plant and is used in various baking recipes, including bread and cakes. While it is a good source of dietary fibre, potassium, magnesium, and vitamin C, it is also high in carbohydrates, which can lead to sugar cravings and energy spikes.

The glycemic index (GI) of a food is a measure of how quickly it raises blood sugar and insulin levels. Cassava flour has a high GI score, with some sources giving it a value of 94, while others give it a value of 105. This is much higher than the GI of table sugar, which is 65. This means that consuming cassava flour can cause a rapid increase in blood glucose and insulin levels, which is not ideal for people following a keto diet or those at risk of metabolic imbalances such as insulin resistance, diabetes, and obesity.

In addition to its high GI score, cassava flour also contains maltose, a sweetener that can further contribute to blood sugar spikes. Cassava flour is also low in thiamine, which is a vitamin B1 that is necessary for metabolising carbohydrates. A diet high in carbohydrates and low in thiamine can lead to a thiamine deficiency, resulting in symptoms such as fatigue and poor memory.

Furthermore, cassava flour has been found to contain cyanogenic glycosides, which can release cyanide into the body if consumed in raw form. While properly processed cassava flour is safe to eat, it is important to note that it can still interfere with the absorption of essential nutrients. This is especially concerning in populations where malnutrition is prevalent.

Overall, while cassava flour has some nutritional benefits, its high carbohydrate content and potential to cause blood sugar spikes make it unsuitable for a keto diet. It is important for individuals following a keto diet to choose alternative flours with lower GI scores and higher nutritional content to maintain ketosis and support their health goals.

It can lead to vitamin B1 deficiency

Cassava flour is not recommended for people on the keto diet because it contains a high amount of carbohydrates, which can lead to sugar cravings and energy spikes. However, a more concerning issue is the lack of thiamine, or vitamin B1, in cassava flour.

Thiamine is an essential vitamin that plays a crucial role in metabolic reactions that transform food into energy. It aids in converting carbohydrates into glucose, which is the body's primary fuel source. A thiamine deficiency can have severe health implications due to its vital role in the body's energy production and nervous system functioning.

The lack of thiamine in cassava flour can lead to vitamin B1 deficiency, especially if cassava flour is consumed in large amounts or as a staple food. Vitamin B1 deficiency can cause a range of symptoms, including fatigue, weakness, reduced appetite, confusion, memory problems, and peripheral neuropathy characterised by numbness or tingling sensations in the hands and feet.

In extreme cases, prolonged vitamin B1 deficiency can contribute to mental health issues such as depressive symptoms and, in the most severe cases, Wernicke-Korsakoff syndrome, a severe neurological disorder. Additionally, vitamin B1 deficiency can lead to congestive heart failure, also known as wet beriberi, where the heart struggles to pump blood efficiently, resulting in fluid build-up in the lungs and causing shortness of breath and other complications.

Therefore, it is important for individuals on the keto diet to be mindful of their vitamin B1 intake and consider alternative flour options that are lower in carbohydrates and richer in essential nutrients, such as almond flour, lupin flour, or sunflower seed flour.

It can disrupt ketosis

Cassava flour is not keto-friendly as it can quickly disrupt ketosis. This is because it is high in net carbs, which can interfere with fat-burning and ketone production.

The number of carbs in cassava flour varies depending on the brand and processing method, but it typically contains around 100 grams of net carbs per cup. This is more than a cup of regular white flour, which has 92 grams of net carbs per cup. As a result, consuming cassava-containing foods can quickly exceed your daily net carb count, which should be limited to 20 to 50 grams to maintain ketosis.

Cassava flour also has a high glycemic index (GI) of 94, which is almost as high as pure glucose, which has a GI of 100. This means it can cause significant spikes in blood sugar and insulin levels, further disrupting ketosis.

In addition, cassava flour contains maltose, a sweetener with a GI score of 105, which is higher than table sugar's GI of 65. This means it can spike blood glucose and insulin levels even more than sugar.

Therefore, cassava flour is not recommended for people on a keto diet as it can quickly disrupt ketosis and block the body's ability to burn fat as an energy source.

It is not a good option for keto baking

Cassava flour is not a good option for keto baking. This is because it is high in net carbs, which can quickly exceed your daily net carb count, interfering with ketone production and potentially inhibiting or slowing down ketosis.

To maintain ketosis and keep your body in fat-burning mode, it is crucial to limit your daily net carb intake to 20-50 grams. Cassava flour contains around 100 grams of net carbs per cup, which is more than a cup of regular white flour. This can quickly push you out of ketosis and disrupt your body's ability to burn fat.

Cassava flour also has a high glycemic index (GI) of 94, which is a measure of how quickly a food raises blood sugar and insulin levels. This is almost as high as pure glucose, which has a GI of 100. As a result, cassava flour can cause significant spikes in blood sugar and insulin levels, making it incompatible with a low-carb ketogenic diet.

In addition, cassava flour contains maltose, a sweetener with a GI score of 105, which is much higher than table sugar's GI of 65. This means it can spike blood glucose and insulin levels even more than sugar.

Furthermore, cassava flour has very low levels of thiamine (vitamin B1), which is necessary for metabolizing carbs. Consuming cassava flour can lead to a thiamine deficiency, resulting in symptoms such as fatigue and poor memory.

For these reasons, it is best to avoid cassava flour when following a keto diet and opt for alternative flours with lower carb counts, such as almond flour, coconut flour, or sunflower seed flour. These alternatives will allow you to stay within your daily net carb limit and maintain ketosis.
