Is drinking soda really such a bad habit?
Dr. Oz and other experts reference studies (Am J Clin Nutr August 2006 vol. 84 no. 2 274-288) that suggest that drinking liquid calories is helping to fuel the obesity crisis. Other studies suggest that even diet sodas, a cornerstone beverage of many diet programs, may confuse the mind by offering a sweet taste, but no energy calories, so your brain sends hunger signals to instigate eating.
Beyond those theories though is recent research that suggests a relationship between risk of a stroke and soda consumption. Research at Harvard University, and Cleveland Clinic’s Wellness Institute, links sugar-sweetened soda and diet soda to stroke risk. The researchers had expected the regular soda to have a link because of other studies that identify coronary artery disease, high blood pressure, diabetes, weight gain and increased risk of diabetes in people who regularly consume soda. The diet soda and stroke connection is a bit more puzzling, and the researchers are looking at the caramel coloring and other possible mechanisms.
