Studies show that people who drink sugary drinks daily are more likely to gain weight and develop obesity than those who avoid these drinks.
Effects on bone health
A common concern regarding soft drinks is the risk of bone weakness. Although phosphoric acid is thought to affect calcium metabolism, a direct link has not been proven.
The real problem is substitution: people often drink soda instead of calcium-rich drinks (like milk), which reduces calcium intake.
Adequate calcium intake can counteract the negative effects of caffeine and maintain healthy bones in the long term.
Carbonated waters without sugar, phosphoric acid or caffeine (e.g., carbonated mineral water) are considered not harmful to bone health.
Blood sugar and diabetes risk
Sugary sodas cause a rapid rise in blood sugar levels and increase insulin resistance over time. Even one can of soda per day is associated with an increased risk of type 2 diabetes. According to one study, an additional 150 sugary calories per day increase the risk of diabetes by 1.1%.
