The word “sugar”— does it mean blood sugar (glucose) or dietary sugar (glucose-fructose)? The food industry says “you need sugar to live”—but while you do need a blood glucose level to live, you don’t have to consume that glucose. In fact, your liver can make glucose from the glycerol (see Fig. 7–3d) released from the breakdown of triglycerides in either dietary fat or body fat, or from amino acids, a process called gluconeogenesis.
