Surveys show that people who drink diet sodas rarely stop with just one. People are drinking diet sodas at an average of more than 26 ounces per day. The more hardcore you become, the closer you begin to look like a fiend.
Does an artificial sweetener trigger the brain’s reward system, thus making you an addict to diet soda? In a study of women who drank water sweetened with sugar or Splenda, the women couldn’t taste the difference between the two, but functional MRIs showed that the brain’s reward system responded more strongly to sugar.
Beyond the addiction issue, diet soda has been linked to increased rates of heart attack and stroke, kidney problems, preterm deliveries, and, weight gain. The emerging evidence is a bit disturbing. Here’s a rundown:
- Heart Attack and Stroke: Drinking diet sodas daily may increase the risks for heart attack and stroke and other vascular events by 43 percent, but no such threat exists with regular soft drinks or with less frequent consumption of diet soda. These results come from a study including more than 2,500 adults published online in the Journal of General Internal Medicine on January 30, 2012. So far, no one knows what it is about diet sodas that could explain the added risk.
- Kidney Trouble: In 2009, researchers at Harvard found that drinking two or more diet sodas daily could lead to a 30 percent drop in a measure of kidney function in women. No accelerated decline was seen in women who drank less than two diet sodas daily. The drop held true even after the researchers accounted for age, high blood pressure, diabetes and physical activity.
- Preterm Delivery: A Danish study including more than 59,000 women found a link between drinking one or more diet sodas daily and a 38 percent increase in the risk of giving birth to preterm babies; the risk was 78 percent higher among pregnant women who drank four or more diet sodas daily. No such risk was seen with regular soda.
- Weight Gain: Wouldn’t it be ironic if instead of helping you lose weight, diet sodas had the opposite effect? A study at the University of Texas Health Science Center at San Antonio found that compared to those who drank no diet sodas, study participants who did had a 70 percent greater increase in waist circumference; worse, drinking two or more diet sodas daily led to ballooning waist circumference that was 500 percent greater than those who drank none. This doesn’t prove that diet soda is to blame since the study was observational – it could be that participants began gaining weight and then started drinking diet sodas.
The bottomline, have a nice tall glass of ice water!
