5. Sugar accelerates aging.
It even contributes to that telltale sign of aging: sagging skin. Some of the sugar you consume, after hitting your bloodstream, ends up attaching itself to proteins, in a process called glycation. These new molecular structures contribute to the loss of elasticity found in aging body tissues, from your skin to your organs and arteries7. The more sugar circulating in your blood, the faster this damage takes hold.
6. Sugar causes tooth decay.
With all the other life-threatening effects of sugar, we sometimes forget the most basic damage it does. When it sits on your teeth, it creates decay more efficiently than any other food substance8. For a strong visual reminder, next time the Tooth Fairy visits, try the old tooth-in-a-glass-of-Coke experiment—the results will surely convince you that sugar isn’t good for your pearly whites.
