Confusion regarding "sugar"!!?!

Confusion regarding "sugar"!!?

Hi,
I associate the sugar that we take in tea,coffee etc and the sugar level that we talk about in our body. Are they same thing? I mean if I take this raw sugar, does this increase the sugar level in my blood proportionately.? Or for that matter, can I associate sugar with sweetness, and can say that if I take anything sweet, it will increase level of sugar in my blood and give me instantaneous energy..?
Where does glucose fit in this overall picture?

Thanks for answering these basic questions with clarity!

I have two chapters in my blog that fully explains sugar and its effects on our body.
