The combined results of this new study showed that just one 12-fl oz. can (355 ml) of diet soda daily leads to:
– 42 percent higher leukemia risk in men and women (pooled analysis)
– 102 percent higher multiple myeloma risk (in men only)
– 31 percent higher non-Hodgkin lymphoma risk (in men only)
These results were based on multi-variable relative risk models, all in comparison to participants who drank no diet soda. It is unknown why only men drinking higher amounts of diet soda showed increased risk for multiple myeloma and non-Hodgkin lymphoma. Note that diet soda is the largest dietary source of aspartame(by far) in the U.S. Every year, Americans consume about 5,250 tons of aspartame in total, of which about 86 percent (4,500 tons) is found in diet sodas.
