What are the three main types of carbohydrates?

The three main types of carbohydrates are sugars, starches, and fibers, which all play essential roles in nutrition and energy provision. Sugars, also known as simple carbohydrates, are sweet in taste and easily digestible, providing quick sources of energy. Starches are complex carbohydrates made up of long chains of glucose molecules, offering a more sustained energy release as they take longer to digest. Fibers, another form of complex carbohydrate, are not digestible and serve important functions in digestive health, such as promoting regular bowel movements and aiding in cholesterol management.

This classification is foundational in understanding how carbohydrates function in the body, including their roles in energy metabolism and the regulation of blood sugar levels. Recognizing the different forms of carbohydrates allows for better dietary choices and understanding of food labels. The other options listed incorporate categories not classified as carbohydrates, which makes them inappropriate in the context of this question.
