Which of the following are classified as simple sugars?

Simple sugars refer specifically to the most basic forms of carbohydrates, known as monosaccharides and disaccharides. Monosaccharides include single sugar molecules like glucose and fructose, while disaccharides are composed of two monosaccharides linked together, such as sucrose (table sugar) and lactose (milk sugar).

The reason this choice is correct lies in the definition of simple sugars, which are quickly absorbed by the body and can provide immediate energy. This differentiates them from other types of carbohydrates, such as polysaccharides and complex carbohydrates, which are made up of longer chains of sugar units and require more time for digestion. Additionally, polyunsaturated fats are a type of fat and not related to sugars at all.

Understanding these classifications helps you recognize how different carbohydrates function in the body, how they are metabolized, and their role in nutrition and energy levels.
