Coca cola is a sugary concoction made from high-fructose corn syrup, artificial flavorings, and a cocktail of preservatives. You shouldn't be surprised it's a leading cause of obesity and dental decay. Just drink water.
Why trash
Liquid sugar (or artificial sweeteners). 39 grams of high-fructose corn syrup per can.
Try instead
Sparkling water with lemon, or seltzer water with a squeeze of real lime or orange.
