What best describes complex carbohydrates?

Complex carbohydrates consist of long chains of sugar molecules, which makes them digested more slowly compared to simple carbohydrates. This slower digestion leads to a more gradual release of glucose into the bloodstream, providing a sustained energy supply rather than a quick spike and drop in blood sugar levels. This attribute makes them ideal for maintaining energy levels over extended periods, as they help stabilize blood sugar levels.

While other characteristics such as fiber content are associated with complex carbohydrates—since many complex carbs, like whole grains and legumes, are indeed high in fiber—the defining feature that directly relates to their impact on energy levels is their ability to provide a steady stream of glucose. Simple carbohydrates, on the other hand, can lead to quick energy bursts followed by crashes, which is not the case with complex carbohydrates. Thus, understanding the role of complex carbohydrates in relation to energy release is critical for proper nutrition and wellness.
