False. The chemical bonds between the sugar units in fiber cannot be digested by human enzymes in the GI tract.
Fiber
Fiber is a polymer of simple sugars linked together by glycosidic bonds.
The bonds that link the monomer units in fiber are beta configurations and the chain of sugars is unbranched, making it difficult for enzymes and water to break them.
This is unlike what is obtainable in carbohydrates such as starch in which the monomers are linked by alpha configurations and the chain branched, making it easy for enzymes to break the bonds.
