Diet drinks linked to heart disease?

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.

  1. This study is about as significant as a study showing more people die from cancer in a cancer hospital than those who don’t go to one.

    Pure junk science to raise research funds from the anti-adpartame crowd. I don’t mind them wasting their money, but groups such as those have a nasty tendancy to force their beliefs on the rest of us. I wonder how many deaths are attributable to CSPI demanding that food businesses replace saturated fat with trans fat?

  2. The great thing about heart disease is that it’s far and away the number one cause of death in the US since “old age” is no longer an option. That practically guarantees that any subgroup targeted for a specific behavior is likely to have more members with heart disease than without. That being said, if “1 in every 4″ Americans die of heart disease, doesn’t any number under 25% indicate the product is acting as a preventative?

    Of course, that’s not even getting into the problems with 60,000 middle aged women answering a survey being considered medical research.

  3. Another garbage study, but let’s say the correlations are real: they could be explained by looking at dieting behavior among the diet soda drinkers. Dieting, as well as diet pills and supplements, have been resoundly shown to adversely affect the heart and blood pressure. It’s not the sodas themselves, which has no biological plausibility.
