Verified step by step guidance

Understand the concept of polysaccharides: Polysaccharides are long chains of monosaccharides (simple sugars) linked together by glycosidic bonds. They serve as energy storage (e.g., starch, glycogen) or structural components (e.g., cellulose). Foods rich in polysaccharides typically contain starch or fiber.
Analyze the composition of white rice: White rice is primarily composed of starch, which is a polysaccharide. Starch is a storage form of glucose in plants and is broken down into glucose during digestion.
Evaluate honey: Honey is mostly composed of simple sugars like fructose and glucose, not polysaccharides. It is a source of quick energy but does not contain significant amounts of starch or fiber.
Examine milk: Milk contains lactose, a disaccharide (two sugar molecules linked together), along with proteins and fats. It does not contain polysaccharides as a major component.
Assess table sugar (sucrose): Sucrose is a disaccharide composed of glucose and fructose. It is not a polysaccharide and does not provide the long chains of sugar molecules characteristic of polysaccharides.
