What are starches primarily known for?

Starches are primarily known for being the principal source of glucose, which is a vital energy source for the body. When consumed, starches are broken down into glucose through the process of digestion. This glucose is then utilized by cells for energy, making starches an important component of the diet, particularly for individuals engaged in physical activities.

Unlike options that suggest a focus on fiber, fats, or protein, starches specifically serve as a carbohydrate source. While some starchy foods may contribute fiber or have small amounts of protein, their primary function in nutrition is to provide a readily available form of energy through glucose. This is essential for maintaining energy levels during both rest and physical exertion.
