ADVERSE HEALTH EFFECTS OF CARBONATED SODA

Soft drinks contain carbonated water as the key ingredient. Although the carbonation itself isn't necessarily unhealthy, some of the additives in carbonated soda can be harmful. The phosphoric acid in carbonated soda can interfere with calcium absorption and weaken teeth. Too much sugar and caffeine can have negative side effects. Carbonated soft drinks also aren't nutritious. They contain empty calories.

PHOSPHORIC ACID

Although phosphoric acid adds a tangy flavor to colas and other carbonated beverages, over time it can soften and erode tooth enamel, according to the Academy of General Dentistry. Your saliva helps neutralize acidity, allowing tooth enamel to re-harden, but drinking carbonated soda regularly may not give the enamel enough time to re-harden. Once the enamel is gone, the inner tooth can be damaged. Foods and beverages with a pH value below 4 can cause tooth erosion. Colas have a pH value between 2.4 and 2.5.

CAFFEINE

Generally, moderate caffeine consumption isn't harmful for most people. However, you may be too dependent on it if you experience headaches, sleep problems or heart palpitations. Excessive caffeine consumption can also cause dehydration and gastrointestinal distress, warns Beth Czerony, a registered dietitian at Cleveland Clinic. Soft drinks are a popular source of caffeine, particularly for teenagers. Soft drinks other than colas also contain varying amounts of caffeine. 

Children younger than age 12 and pregnant women should avoid consuming caffeine. Because pregnant women can pass the stimulant on to their babies, the South Dakota Department of Health recommends no more than 300 mg of caffeine a day if you are pregnant. Caffeine remains in your unborn baby's bloodstream longer. Sodas with caffeine should not replace milk in a child's daily diet. Children need adequate calcium intake to build strong bones. Children should limit their caffeine consumption to less than 35 to 40 mg a day.

SUGAR

While sugar itself does not cause diabetes, high sugar intake raises blood glucose levels, which can lead to a variety of health problems including diabetes, high blood pressure, heart disease and stroke. People who consume a lot of foods and beverages, like carbonated sodas to which sugar has been added, often have higher body mass indexes -- an indicator of how much of your body weight is fat. Being overweight or obese is a known risk factor for diabetes. Carbonated sodas have no nutritional value yet are packed full of calories.

SUGAR SUBSTITUTES

Artificial sweeteners found in diet sodas may not increase your risk of cancer and other diseases, but they can leave an aftertaste. Many of the foods and beverages that contain sugar substitutes contribute few nutrients. Although artificial sweeteners are generally considered safe, they offer no health benefits.
