A study published Saturday says women who drink two or more diet sodas a day are 30% more likely have a cardiovascular even and 50% more likely to die than women who rarely drink diet sodas.CNBC’s report of the study has the scary headline based on a study by Dr. Ankur Vyas, a cardiovascular disease expert at the University of Iowa Hospitals and Clinic and presented in the meeting of the American College of Cardiology. Their research found that 8.5% women who had 2 or more diet sodas a day had heart disease, while compared to 6.8% of those who had 4 or fewer per week. 7.2% of those who essentially abstained had heart disease. This supposedly shows an association. The percentages look more like 25% more having heart disease, not 30%, in the heavy and medium(?) consumers. It also looks like having an occasional diet pop is better than tee totaling.
I’m not sure how they get to this conclusion because as the article mentions the women with the higher heart disease rates have other factors (smoking, overweight, diabetes) than the others. If diet soda caused heart disease, then it would appear that the causal agent would be identified. It also doesn’t seem to explain the higher rate of heart disease from avoiding diet drinks. This research will likely fuel the anti-aspartame crowd.
