"The active ingredient in most soda pop is phosphoric acid. The pH of most soda pop is 2.8, which is very acidic. As we discuss in detail in the body PH page, you want your diet to ALKALIZE your body, and ingesting a highly acidic drink like soda pop does the opposite and is very detrimental to your health. Phosphoric acid also leaches calcium from bones and is a major contributor to the rising increase in osteoporosis.
Animal studies show that phosphoric acid, a common ingredient in soda pop, can deplete bones of calcium.
And recent human studies suggest that girls who drink more soda pop are more prone to broken bones. The soft drink industry denies that soda plays a role in bone weakening."
