While they can be refreshing on a hot summer's day, drinking soft drinks such as Coca-Cola (coke) can be bad for your health. While the occasional soda won't kill you, you should not consume them on a daily basis. There are several reasons why you should consider eliminating soft drinks from your diet.
Regular soft drinks have a very high sugar content. The most popular soft drink brands contain about 39 grams of sugar per 12 ounces, which is the can size that is usually bought in a machine or a 12-pack of soft drinks. Some soft drinks that give you extra energy because of their high caffeine contact also have a high sugar content, about 77 g per 12-ounces. Drinking all of that sugar can lead to obesity, diseases such as diabetes, and it can cause tooth decay.
Caramel Colouring and Cancer
The most popular soft drinks in the world contain a caramel colouring that has been linked to cancer. Long-term exposure to the artificial chemical that is used to colour these soft drinks, 4-methylimidazole (4-mel), was shown to cause lung cancer in mice. In California, products with this chemical in them that have over 29 micrograms have to be labelled as toxic. In tests that were done on soft drink in cans and bottles, the levels of 4-mel were over 29 micrograms in most tests.
Blood Sugar Spikes
Even though most people consider diet soft drinks a bit better than regular soft drink because they don't contain sugar, the artificial sweeteners they contain can cause spikes in your blood sugar. These spikes in blood sugar can contribute to problems that many people do not associate with diet sodas, such as weight gain and diabetes.
In order to avoid health problems associated with soft drinks, you should limit your intake of them or switch to drinking water or unsweetened tea.
