1) Cola beverages linked to kidney disease.

The New York Times article reports:

  Colas contain high levels of phosphoric acid, which has been linked to
  kidney stones and other renal problems.
  
  Much of this conclusion stems from anecdotal and circumstantial
  evidence. So last year, a team of scientists at the National Institutes
  of Health took a closer look.
  
  In a study published in the journal Epidemiology, the team compared the
  dietary habits of 465 people with chronic kidney disease and 467 healthy
  people. After controlling for various factors, the team found that
  drinking two or more colas day a whether artificially sweetened regular
  or was linked to a twofold risk of chronic kidney disease.
