Why it's harmful: Sodas have strong phosphoric acids. Phosphoric acid is used by automotive mechanics to clean the rust and junk off battery terminals. Imagine what this does to your teeth, gums, and bones in your mouth.
What to substitute: You can drink water or herbal tea or just take a few days off from soda each week.
How to reduce harmful effects:
1.Drink soda through a straw to minimize exposure.
2.Drink your soda in one sitting. Nursing one soda throughout the afternoon is harder on your teeth than drinking it quickly in one sitting because of the prolonged exposure.
