The digestion of tapioca starch begins in the mouth, where enzymes in saliva start breaking down the starch into simpler sugars. Once the starch reaches the stomach, it continues to be broken down by stomach acid and enzymes. The resulting mixture of sugars and other nutrients then moves on to the small intestine, where more enzymes are secreted from the pancreas and the small intestine itself to continue breaking down the starch into its component sugars.
Tapioca starch is made up of long chains of glucose molecules, which means that it is classified as a complex carbohydrate. While complex carbohydrates can take longer to break down and digest than simple sugars, the refining and processing of tapioca starch means that it is quickly broken down and absorbed by the body. As a result, tapioca starch is considered easy to digest and is often used in foods for individuals with digestive issues or sensitivities. However, it is important to consume tapioca starch in moderation, as consuming large amounts of any type of refined carbohydrate can lead to spikes in blood sugar levels and other health issues over time.
