If every American replaced the soda in their diet with water or unsweetened tea, it would have a massive positive impact on our nation's overall health.
Sodas by and large are sources of empty calories fueled by massive quantities of sugar.
Two of the worst you can choose are Mountain Dew and Mello Yello, two popular citrus-flavored soft drinks.
A 20-ounce bottle of Mountain Dew contains a staggering 77 grams of sugar, and the same size bottle of Mello Yello contains 78 grams.
For reference, the latest federal guidelines recommend that people limit their added sugar consumption to between 40 and 48 grams per day.
And don't think diet sodas are going to save you. While those drinks may not contain the amount of sugar of their full-caloried siblings, the artificial sweeteners used in diet sodas have a negative impact on the brain's ability to tell your body when you're full, which leads to overeating.
In fact, a 2014 study discovered that diet soda drinkers ate more calories from solid food than those who drink regular soda.
