Glucose is just the simplest unit of sugar, it is not quite as sweet as sucrose, but it is still sweet. It is also still refined, you don't just find glucose in the form of brewers sugar in nature.
I am not against the idea of cutting back on sugar, that is a great idea. I do have to question some of the above logic though.

Anyway, back to the topic... it is just sugar in its simplest form. Best type for making homebrew as it gets broken down completely in the brewing process unlike normal sugar. You can cook with it or use it to sweeten things if you want to. Or just find someone who makes homebrew and give it to them. I guess they are just handing out all the donated goods in your packs, sugar is sugar if you are desperate.
