Big Number: Diet drinks linked to 23 percent increase in stroke risk in women
Washington Post

Swapping regular sodas for diet drinks might seem like a smart way to cut calories. But new research suggests that women who drink a lot of artificially sweetened beverages increase their risk of having a stroke by 23 percent. What’s a lot? At least two diet beverages a day for this study. Those women are 31 percent more likely to have the most common type of stroke — an ischemic stroke, which is caused by a clot. The findings came from the analysis of about 12 years of health data on 81,714 women 50 and older. The researchers compared women who drank two daily diet sodas or fruit drinks with those who drank such beverages less than once a week or not at all. The study did not identify the specific artificial sweeteners that the drinks contained.
