Drink just one soda per week

Soda can have serious health affects. Firstly, it's nothing but pure empty calories sugar without any nutrients. And those calories won't go anywhere but your waistline. Secondly, most sodas contain high fructose corn syrup, which is a super sweet syrup that can spike your blood sugar and even trick the liver into producing more artery clogging chemicals. If that weren't enough to convince, consider the fact that there's evidence that the common soda preservative sodium benzoate can directly damage DNA and disable mitochondria, the powerhouse of the cell.
