Human: What are the different types of sugar? Assistant: 
The different types of sugars include monosaccharides, disaccharides, oligosaccharides, polysaccharides, and sugar alcohols. Monosaccharides are simple sugars that can be found in fruits and vegetables. Disaccharides are two simple sugars joined together. Examples include sucrose (table sugar) and lactose (milk sugar). Oligosaccharides are short chains of two or more monosaccharides linked together. Polysaccharides are long chains of several monosaccharides linked together. Sugar alcohols are alcohol derivatives of monosaccharides. They are often used as sweeteners because they are not digested by the body.
