What is the primary carbohydrate found in a standard Western diet?

Explanation

Among the carbohydrates, starch is the main source consumed in a typical Western diet, as it is abundant in foods like potatoes, bread, and pasta. Glycogen is a storage form of carbohydrate in animals, sucrose (table sugar) is a common sugar but not the main carbohydrate source, and cellulose is a fiber not digestible by humans.
