What is considered a normal blood sugar level, and how do these values vary between fasting and postprandial states?

• 80-100 mg/dL (or lower if you don't consume sugar)

This is the ratio of how much sugar you have in your blood. The average American consumes 31 teaspoons of sugar every day, which is 130-145 pounds of sugar per year.

Such consumption will lead to above-average blood sugar levels.
