The Surprising Truth About Cassava Flour: Is It High In Oxalates?

Oxalates are naturally occurring compounds found in various plants, including cassava. They have been linked to health concerns such as kidney stones and digestive issues. Therefore, it’s essential to understand whether cassava flour, a popular gluten-free alternative, is high in oxalates.

Understanding Oxalates

Oxalates are organic acids that can bind to minerals like calcium, forming insoluble salts. These salts can accumulate in the kidneys and urinary tract, potentially leading to kidney stones. However, it’s important to note that not all oxalates are harmful. Some oxalates are soluble and can be excreted through urine without causing any issues.

Cassava Flour and Oxalates

Cassava flour is made from the root of the cassava plant. It’s a good source of dietary fiber, resistant starch, and other nutrients. However, it also contains oxalates. The oxalate content of cassava flour varies depending on the specific variety of cassava used and the processing methods.

Is Cassava Flour Safe for People with Oxalate Sensitivity?

The oxalate content of cassava flour is generally considered moderate compared to other oxalate-rich foods like spinach and rhubarb. However, people with oxalate sensitivity or a history of kidney stones may need to limit their intake of cassava flour.

How to Reduce Oxalates in Cassava Flour

There are several ways to reduce the oxalate content of cassava flour:

Soaking and Fermenting

Soaking cassava flour in water for several hours or fermenting it for a few days can significantly reduce oxalate levels.

Cooking

Cooking cassava flour in boiling water can also leach out some oxalates.

Combining with Calcium-Rich Foods

Consuming cassava flour with calcium-rich foods like dairy products or leafy green vegetables can help bind oxalates and prevent them from being absorbed.

Health Benefits of Cassava Flour

Despite its oxalate content, cassava flour offers several health benefits:

Gluten-Free

Cassava flour is naturally gluten-free, making it a suitable alternative for people with celiac disease or gluten intolerance.

Rich in Dietary Fiber

Cassava flour is a good source of dietary fiber, which promotes digestive health and satiety.

Resistant Starch

Cassava flour contains resistant starch, a type of dietary fiber that resists digestion and has beneficial effects on blood sugar control and gut health.

Other Nutrients

Cassava flour also provides essential nutrients such as potassium, magnesium, and vitamin C.

Takeaways: Navigating Cassava Flour and Oxalates
