than glucose and galactose, but also decreases its absorption compared to
glucose and galactose.
Soon our bodies become overloaded with
fructose, the liver can no longer handle the quantity, and it becomes more toxic
than glucose.
They can state «no sugar» or «low sugar» on the nutrition label because maltodextrin is a complex carbohydrate, but it will impact blood sugar more
than table sugar (table sugar is sucrose, which, by the way, is not a simple sugar — it is two molecules,
glucose and
fructose, bonded together).
