Most Americans drink an average of one and a half cans of soda a day. That doesn't seem like much, but the sugars, chemicals, and caffeine found in even 20oz. of soda ought not to be ignored. Since I have a little one, I find myself being increasingly aware of the foods we eat. In studying nutrition, soda comes up as the number one danger food.
Mineral Loss in Bones
Caffeine causes mineral loss in bones. According to a recent study, caffeine cause a depletion of minerals in the bones-especially calcium. There is no valid scientific proof that it stunts bone growth, but there are studies showing a bone mineral loss and weaker-less dense bones as a result of caffeine intake. http://www.sciencedirect.com/science/article/pii/S8756328201006597
Tooth Corrosion
Soda also destroys tooth enamel. In fact the sugar in soda is not the major concern, it is actually the acids in the soda. According to research, "Root beer could be the safest soft drink for your teeth, new research suggests, but many other popular diet and sugared sodas are nearly as corrosive to dental enamel as battery acid." http://www.sugarstacks.com/beverages.htm. Battery acid has a ph of 1.0 while Coke has 2.25 ph. Colas are the most dangerous kind of soda. My mom used to use coke to clean rust off metal. "The erosive potential of colas is 10 times that of fruit juices in just the first three minutes of drinking, a study last year showed. The latest research, published in Academy of General Dentistry (AGD) journal General Dentistry, reports that drinking any type of soft drink hurts teeth due to the citric acid and/or phosphoric acid in the beverages." http://www.sugarstacks.com/beverages.htm.
Weight Gain
Both diet and regular sugared sodas cause wight gain. Artificially sweetened soda raises blood sugar just like regular sugar does. People who drink either regular or diet soda both gain weight. It doesn't make a difference what kind they drink. Aspartame has been proven to be an appetite increase causing people to want to eat more after drinking a diet soda. The calories found in a can non-diet soda is comparable to eating a turkey sandwich-basically-lunch.
Diabetes
Since drinking soda is usually the main reason for weight gain in most Americans. People who are overweight are at a higher risk for high blood pressure and diabetes. Large quantities of sugar has also been attributed to making a pancreas disfunctional, leading to diabetes.
