It is possible to classify them further as simple or complex carbs, depending on the number and type of sugar molecules — such as glucose — that each structure contains.

Also called “simple sugars,” “sugars,” or “saccharides,” these carbohydrates contain between one and 10 sugar molecules and are present in fruits, vegetables, and dairy products.

Those with one or two sugar molecules are called monosaccharides and disaccharides, respectively, while those containing up to 10 sugar molecules are called oligosaccharides.

Lactose — the main sugar in animal milk — is a disaccharide comprising the monosaccharides glucose and galactose.

Oligosaccharides, however, are mid-length prebiotic carbohydratesTrusted Source that are in fiber-rich foods and human milkTrusted Source.

Complex carbohydrates are made up of polysaccharidesTrusted Source, which are longer, intricate chains of sugar molecules.

Complex carbs include both starches and dietary fiber.
Starches are the storage carbohydrates in peas and beans, grains, and vegetables, and they provide the body with energy.
