Is diet soda healthy?

Diet soda and diet coke are carbonated drinks containing no calories. They are sweetened with artificial sweeteners such as aspartame and sucralose.

Many people assume these drinks are healthy because they contain no sugar. These drinks cannot be considered healthy for the following reasons:

  • They are loaded with artificial sweeteners such as aspartame (400 times sweeter than sugar). They confuse the body’s metabolism and change taste sensations for other foods. Surprisingly, diet drinks trigger insulin secretion and contribute to fat accumulation in the body.
  • Diet drinks contribute to weight gain. Diet drinks are now believed to contribute to long-term weight gain and to increased waist circumferences. Researchers have ideas to what causes these reactions but so far, the precise mechanisms continue to be elusive.
  • The University of Minnesota’s research has revealed that individuals who consume diet coke have a 67% greater chance of developing of diabetes and a 36% greater chance of developing metabolic syndrome.
  • The American Academy of Neurology has revealed that consuming diet coke > 4 cans/day can also lead to depression.
  • The American Journal of Clinical Nutrition has published a study which says that diet coke consumption decreases bone mineral density and increases the risk of developing osteoporosis.
  • There is a 30% greater chance of decreased kidney functioning.
  • The citric acid component in diet coke destroys tooth enamel, which leads to tooth erosion.
  • Diet coke can trigger migraine headaches. The most common side effect of aspartame in diet coke is headache.


There is correlation between the consumption of diet coke and increased weight gain, obesity and other disease conditions. Replacing regular soda with a diet soda may cut down calories, however, there are untoward effects of diet soda. Having 1-2 cans a day may not affect our health but drinking excessive diet soda assuming that it is a healthy drink may have undesirable effects.
