Each year, Americans consume about 5,250 tons of aspartame in total, of which about 86 percent (4,500 tons) is from the consumption of diet sodas. Diet soda is the largest dietary source of aspartame in the U.S. A study recently published at the beginning of December 2012 links the consumption of Aspartame to increased risk of Lymphoma and Leukemia. As few as one diet soda daily may increase the risk for leukemia in men and women dramatically. The study was conducted by the Channing Division of Network Medicine, Department of Medicine, Brigham and Women’s Hospital and Harvard Medical School, Boston, MA and Nutrition, Harvard School of Public Health, Boston, MA. The study was a follow up after a 22 year period of data collection including health frequent dietary and health check ups of the study group.
