Sugary drinks' link to high blood pressure. (Thanks, Instapundit.)
Growing up, my mom never had soft drinks in the house, never Cokes for example, and she was from Atlanta. The only exception was ginger ale when we were sick. There was also a soft drink called Squirt she would get - not often but sometimes - when we were not feeling well. Those came in 4 oz. bottles. But otherwise, no soft drinks.
