Recent research conducted at both the University of Texas Health Science Center and Harvard Medical School indicates that the artificial sweeteners in diet soda are in fact linked to a number of health issues, including obesity. Aspartame, which is comprised of two amino acids that are connected by way of a peptide bond, has been associated with weight gain as well as altering metabolic pathways in an unhealthy manner. Furthermore, drinking these beverages may cause changes in overall behavior and mental health, and may even lead to further addiction for sugary drinks and foods.
Clinical studies have been conducted at Harvard Medical School on 3,000 women to determine the effects of diet sodas. These women drank two or more diet sodas per day as part of the study, in order to mimic average consumption of diet drinks among a large demographic of women in the U.S. The results of the study, which were published in Prevention 2012, indicate that these women demonstrated a palpable loss of kidney function. Interestingly, women who drank regular soda did not demonstrate kidney dysfunction.
Another clinical study back in 2008 tested 10,000 adults who were given one diet soda per day. The results of this study indicate that their was a 34 percent increase in the risk of metabolic disturbances. Diet sodas are also linked to higher plasma levels of cholesterol and increased levels of belly fat which increases the risk of cardiovascular disease.
The study completed at the University of Texas Health Science Center found that the more diet sodas are consumed daily, the greater the risk for weight gain. In other words, diet soda does not help you to lose weight. Essentially, artificial sugars disturb the body’s ability to control calorie intake and sugar due to crossed signals from chemically improper sweeteners driving metabolisms the wrong way.
Beyond bringing about metabolic disturbances, diet soda also contributes to dental caries as well. Diet sodas are found to be quite acidic and in fact have a pH around 3.2. Hence, drinking 3 or more diet sodas daily contributes to dental problems, in addition to weight gain, liver function issues, and behavior health.
