Foods Containing Glucose or Fructose

Glucose and fructose are simple sugars or monosaccharides. Monosaccharides are the simplest form of carbohydrates and can be combined to form more complex carbohydrates like disaccharides and polysaccharides. Examples of disaccharides and polysaccharides are sucrose (table sugar), lactose (milk sugar) and starch. Most foods contain glucose, fructose or both. Carbohydrates like glucose and fructose are the body’s main source of energy.

Fruits and Vegetables

Glucose and fructose are naturally found in fresh fruits and vegetables. They are also in fruit and vegetable products made with added sugar because glucose and fructose combine to form common table sugar. Examples include jams, jellies, chutneys, canned fruits and vegetables, dried or candied fruits and vegetables, frozen fruit concentrates, fruit pie fillings, fruit drinks, ketchup, pickled sweet cucumbers and relish.

Grains contain glucose but do not naturally contain fructose. However, grain products that are made with sugar will contain both glucose and fructose. This includes bread, baked goods, desserts, snack foods like chips and crackers, instant oatmeal, cereal, granola, frozen pastry dough and instant rice and pasta.


Plain dairy products like milk, yogurt and cheese are a natural source of glucose because glucose is a building block for lactose, the sugar found in milk. Dairy products that contain glucose and fructose include chocolate milk, flavored yogurt and yogurt with fruit on the bottom, ice cream, whipped cream, sherbet, frozen yogurt and sweetened cream cheese.
