Fibre - it is non-digestable
I think your referring to an element, the basic unit(s) that cannot be broken down without fission.
Is a pure substance such as an element. Remember elements can not be broken down further by chemical or physical processes.
All of the elements of the Periodic Table cannot be broken down into simpler substances.
A chemical element, or an element, is a material which cannot be broken down further or changed into another substance by using chemical means.

Two types of material with defined chemical properties are single atoms (iron, carbon, etc.) and molecules made up of several atoms (NaCl. CCl4, etc). If either of these classes of materials is changed it looses its typical chemical properties.

The characteristics of elements are that they cannot be broken down any further by chemical means. They differ by the number of protons in their nuclei.
Aluminum is an element; it cannot be decomposed further using chemical techniques. Feldspar is a family of alumino-silicate minerals, which can be broken down by strong acids.
The atom cannot be broken by chemical methods.
This the atom; it is indestructible by chemical methods.
