Glucomannan
The roots of the konjac plant are the origin of the powdered soluble fiber known as glucomannan. When combined with hot water, it is incredibly absorbent and forms a thick, colorless, odorless gel.
As pure fiber with no calories or carbs, glucomannan is a well-liked alternative to cornstarch for those on low-carb diets. Additionally, it is a probiotic, which means that it feeds the good bacteria in your large intestine and can support the maintenance of a healthy gut. In addition, a recent study discovered that taking 3 grams of glucomannan daily might lower your LDL (bad) cholesterol by as much as 10%. However, when using it as a thickener, you probably won't consume that much. Because it thickens considerably more effectively than cornstarch, you need much less of it. For every 2 teaspoons of cornstarch, most people use around 1/4 teaspoon of glucomannan.
