The good news is that fewer people consume soda – 63 percent avoided it in 2014 compared to 41 percent in 2002, according to Gallup. Industry tracker Beverage Digest says soda consumption is down to a 30-year low. Sugary sodas have been losing to diet ones for several years now. But while people are getting rid of one harmful substance, they are letting several others in. More bad news is the fact that many people may have replaced soda with booze. Alcohol, a psychoactive substance with dependence-producing properties, can cause a lot of harm, but it often depends on the volume of consumption.
