Grains, beans, vegetables and nuts all contain glucose, but not typically very much. Usually bread contains 0.5 gram of glucose or less per 1-ounce slice. Navy or pinto beans also offer less than a half-gram of glucose for a 1-cup serving.

Glycogen is a carbohydrate found in the liver and muscles (as animal source).
