According to Health magazine, some of the adverse effects of diet sodas are weight gain, an increased risk of diabetes and the physical toll taken on the body due to the over-consumption of artificial sweeteners. Diet soda also has no nutritional value.
Health magazine states that the consumption of diet soda has been known to lead to migraine headaches in some people. These are most likely caused by the artificial sweetener known as aspartame, which can be a headache trigger. Those who suffer from migraines are advised to stay away from diet soda.
Drinking diet soda is also harmful to teeth. The citric acid present in diet soda weakens and destroys tooth enamel over time, and once this protective enamel is gone, it cannot be restored. The results are increased tooth sensitivity and a higher likelihood of the teeth rotting and falling out.
The consumption of diet soda has also been found to be associated with depression. A study by the American Academy of Neurology concluded that those who drink four or more cans of soda a day were 30 percent more likely to be depressed than their non-soda drinking counterparts. The risk for depression was shown to be higher if the soda that was consumed was diet.
Diet soda is also said to be bad for bones. Regular consumption can lead to a much higher risk of osteoporosis in women, as well as lower bone mineral density in the hips.
