Why does glucomannan contribute a negligible caloric value to the diet when consumed?
Answer
The small intestine lacks the enzymes necessary to break it down or absorb it as a nutrient.
Glucomannan is classified as an inert or non-digestible carbohydrate. This means that the human digestive system, specifically the small intestine, does not possess the required enzymatic machinery to break down this complex fiber or absorb it for energy. Consequently, the fiber passes through the upper digestive system largely unaltered, leading to its caloric contribution being negligible, which is a key factor in its use in low-calorie food substitutes.
