Which type of carbohydrate is known for being digested quickly?

The type of carbohydrate that is known for being digested quickly is simple carbohydrates. Simple carbohydrates are composed of one or two sugar molecules, such as glucose and fructose (monosaccharides) or sucrose and lactose (disaccharides). Due to their simple structure, they can be rapidly broken down and absorbed into the bloodstream, leading to a quick rise in blood sugar levels.

This quick digestion makes simple carbohydrates a readily available source of energy, which can be beneficial in certain situations, such as after intense exercise or when energy needs are immediate. Foods high in simple carbohydrates include sugars found in fruits (fructose), dairy products (lactose), and added sugars like candy and soft drinks.

Other types of carbohydrates like polysaccharides and complex carbohydrates have more elaborate structures, which take longer to digest due to their longer chains of sugar molecules. Fiber, while being an important part of a healthy diet, is not digested by the human body and instead passes through the digestive system, further distinguishing it from the rapidly digestible simple carbohydrates.
