I posted a news article some time back about heart-risk caused by drinking soda beberages. Today I forund a cool page that lists 8 Ways Soda Fizzles Your Health.
The site's claims are pretty convincing, and I prefer to list some of them:
Cold drink is the most acidic beverage you can buy.
The high levels of phosphorous in them will leach calcium from the bones.
They dissolve tooth enamel
Each additional drink increases risk for obesity by 1.6 times
Children who drink cold drinks break their bones more easily
You can read details in the original Water for Life USA page.
