Sugarcane fibre is not sugar.
Although it originates from sugarcane, the fibre is a distinct component obtained from the plant's stalks. It is a type of dietary fibre that consists of complex carbohydrates such as cellulose, hemicellulose and lignin. These complex carbohydrates are indigestible by the human body and pass through the digestive system mostly intact. Consequently, fibre does not provide any calories or raise blood sugar levels but is instead an excellent source of prebiotics and dietary fibre for gut health improvement.
On the other hand, sugar is a simple carbohydrate and an energy source for the body. It is mostly found in sweeteners such as sucrose (table sugar), fructose (found in fruits and honey), and glucose (found in many foods). When ingested, sugars get broken down and absorbed by the body, providing calories and impacting blood sugar levels. In the below charts, we compare 100g sugar with 100g sugarcane fibre.
