Beginning in 1948, the Framingham Heart Study explored more risk factors for heart disease by tracking a group of patients throughout the year. Now, some of their descendants are involved in the Framingham Osteoporosis Study, a comprehensive study conducted every four years, by researchers at Tufts University in Boston. In 2006, the team investigated the relationship between bone density and carbonated beverages. A total of 2,500 volunteers participated in the study, and the researchers conducted a detailed study of the types of beverages they drank.
They found that women who drank 3 times a cola-flavored carbonated drink (excluding men) had lower bone density in the hip bone. Other carbonated drinks will not have any effect. The researchers came up with the hypothesis that this effect is likely to result from the effects of caffeine and phosphoric acid (the bubble water does not contain this substance), but the latter has not yet been fully understood by humans. This may hinder the absorption of calcium to some extent - but no one knows the specific mechanism. Ten years later, people have yet to agree on ways in which diet can affect bone health.
Thus, drinking water bubbles does not seem to have an adverse effect on bones and stomach. But what about teeth? Any acid (even weakly acidic) will erode enamel? May not be. Although there are few studies on bubble water, there are many studies on other carbonated beverages. Barry Owens of the University of Tennessee School of Stomatology conducted a study in 2007 to compare the effects of different carbonated beverages. According to his research, the original cola is the most acidic, followed by Diet Coke, then coffee.http://www.wxytgas.com/
