Many of us already know that when you regularly drink soda it can erode the enamel on your teeth and cause cavities. But what would happen to your body if you only drank your favorite colas and fruit-flavored sodas?

A video from YouTube channel AsapScience explains the science behind everything that can go wrong with our bodies when we guzzle gallons of soda.

"It's been estimated that one-fifth of the weight gain in the US between 1977 and 2007 can be attributed to soft drinks," the AsapScience video explains. "High-fructose co syrup, which is the primary soda sweetener, is not metabolized in our bodies the same way other sugars are."

In fact, high-fructose co syrup can also lead to increased risks of heart disease and diabetes. Diet sodas aren't much better. Just as sugar and high-fructose co syrup enhance our appetites, so do artificial sweeteners.

Surprisingly, sodas can also prematurely age us by damaging our telomeres -- the protective caps on our chromosomes, which naturally shorten over time.
