Glucose is simple sugar. It's all kinds of sugar, and it's in your blood, and your body needs it for energy. Most Americans sadly consume far more glucose than necessary, and have enlarged gluteus maximus muscles to show for it.

The word glucose is based on an ancient Greek word gleukos which meant "sweet delightful wine." When you're popping one glucose-laden Girl Scout Cookie after another into your mouth, you certainly do feel that delight. You'll probably see the word glucose plenty in biochemistry textbooks. Glucose needs to be in your blood, and a healthy balance of it in your body is indeed as delightful as wine to those ancient Greeks.
