Are all carbohydrates that are consumed converted into glucose? My research tells me that it is the major source of energy for the body's cells. However my confusion stems from the idea that glucose is predominantly from unhealthy sugary refined based products. If one eats good carbohydrates as the major source of energy, then where does this leave them with regards to the bodies major source of energy?
Chris, without wishing to sound patronising, I think you need to check on some of the implications of your metabolic pathways with greater care.
Firstly, note that glucose is one of the major hubs of your carbohydrate metabolism. It is similarly, if not even more, important in many other species' metabolism. I could, but do not, refer to glucose in chemical combination, such as in sucrose or starch.
The fact that you find glucose (uncombined) in many refined foods has nothing to do with it. The mere fact that you find it in refined foods means that it was that part of unrefined food that remained after the process of refining. You find large quantities of free glucose, fructose and sucrose in fruits and vegetables in general, whether raw, cooked, dried, or pickled.
"Good" carbohydrates in our food are not nearly, not roughly, not at all, different from "bad" carbohydrates. It is no good blaming the molecules, they are the same molecules; the evil is in the user. There is no such thing as a molecule that is not bad for you if you take it in the wrong quantities, in the wrong contexts, or at the wrong times. All our best foods are bad for you if you abuse them.
As for your bodily sources of energy, your question demands a sizeable essay which I do not have time to produce at the moment. Check out the metabolic pathways of fats, carbohydrates, and amino acids. You will find that they meet at various hubs, in particular the acetic acid molecule (or acetate, if you like).
Avoid the use of "good" and "bad" in such connections. The good and the bad are to be found in our behaviour rather than our foods.
Bon appetit
