Think you're making a better health choice when you reach for that diet soda? Recent news might force you to think again. A new study of 9,000 middle-aged folks found that regular and diet soda drinkers share the same risk for heart disease, despite the belief that the sugar-free drinks are better for health-conscious folks.

Even though the study's senior author claims that more research will be done to determine what's behind the results, searchers promptly dialed up "diet soda" (+323%), "is diet soda bad for you" (+306%), and "diet coke" (+193%). Additional queries focused on "diet soda and heart disease."

Will this make people kick the sugarless carbonated beverage habit, or will diet soda fans turn to other means to keep the pounds off? Since news of the study broke, we've seen a modest rise in lookups for "liquid diet," "hoodia diet pills," "detox diet," and "lemonade diet recipe"—but it's hardly enough to predict a lasting trend. It's not always easy to break up with those sweet friends.
