Starch is the most important energy source for humans. The body digests starch by metabolizing it into glucose, which passes into the bloodstream and circulates the body. Glucose fuels virtually every cell, tissue, and organ in the body. If there is excess glucose, the liver stores it as glycogen.
Fiber

Starch begins breaking down in your mouth, where saliva surrounds complex starch molecules. As you chew, saliva breaks up starch into simpler carbohydrates called maltose.

From this point, glucose absorbs directly into your bloodstream through intestinal walls, giving energy to cells, including brain cells.
