ok, here's my soda warning and believe me, i struggle with this daily because i LOVE coke and pepsi but......
soda contains calcite, which is a mineral, and calcite is what gives it that lovely fizz. it also leaches the calcium right out of your body, which for us ladies is an issue.
so try your best to cut down, ideally we shouldn't be drinking soda at all but only in my dreams is that ever going to happen.
