I don't know why it keeps getting misread. Soda relative to other food is next to nothing. You typically eat more than you drink if you aren't watching calories... so the food intake contributes more than the soda. Again... by the examples I gave... a soda + a salad is better than a pizza + a diet soda. Sure, you can drop both soda and the pizza and then it makes an additional difference... but the smarter and bigger difference is made by dropping the pizza vs dropping the soda. Sodas aren't the only drinks that contain acid. Many (if not most) fruit juices do... Healthy orange juice not only will rot your teeth (it actually did rot my baby teeth before I was old enough to know better) but the acid in orange juice is so strong that it upsets my stomach. Again... soda = evil, but orange juice = healthy BUT the acidic effects are the same if not worse with the healthy juice. Soda isn't the only place to get sugar either. The things in your mouth don't care if the sugar is from soda or from food. The key is keeping your mouth clean, so rinsing your mouth and flossing after eating is what makes the difference. I have had some cavity problems as an adult... do you know the biggest contributor? Tums. I had a period of my life of some bad stomach issues (among them a gall bladder problem), and I would wake up late at night and need to take some Tums... chew a couple of tablets and go back to bed... only I never thought about the sugar in them... the sugar that stays on your teeth while you sleep all night and helps feed the bacteria that rot your teeth. At least soda is meant to be a food... Why did Tums ever contain sugar? I buy the sugar-free kind now... but it is a medicine, it never needed sugar anyway, especially not given how it is intended to be chewed and most people wouldn't go brush their teeth after chewing a couple of Tums... and that's the only way to be sure you get all the extra gunk off your teeth. Last, but not least... the corn sweetener (if it is bad for you) isn't just in sodas... again, cutting sodas but not doing anything with the rest of your diet is of little value. All due respect... but I doubt that was the only thing you changed. If you did it as a conscious effort you likely increased your exercise which was probably a far greater contributor to the weight loss. That's a LOT of soda (or anything for that matter) to be drinking in a day! I'm arguably quite fat right now, and a 2-liter bottle of Mountain Dew (not diet) lasts me a couple of days if I drink nothing but that with my meals. I suspect too, as above for Herdfan, that if you were trying to lose weight you were at least exercising more if not watching the rest of what you eat as well.
