Blood sugar is literally that: the sugar in your blood. Your blood contains all kinds of important nutrients and other substances that you need to be healthy, including glucose (i.e., sugar), a crucial energy source for your brain and your red blood cells. Blood is the liquid transporter that distributes these compounds to all parts of our bodies.

Sugar (a type of carbohydrate) is one of our body’s main fuels. The other two fuels are fat and protein. I call it “fuel” because our cells literally burn it to do work. It’s this “biochemical” burning of fuel in all of our cells that is our metabolism.

So, How Does Blood Sugar Get Too High?
