Diet soda consumption increases risk for leukemia and lymphoma
According to the longest running study on aspartame as a carcinogen in humans, as few as one diet soda a day may increase the risk for leukemia in men and women, and for multiple myeloma and non-Hodgkin lymphoma in men.
The study’s researchers analyzed data from the Nurses’ Health Study and the Health Professionals Follow-Up Study for a 22-year period. A total of 77,218 women and 47,810 men were included in the analysis, for a total of 2,278,396 person-years of data. Apart from the size of the test subjects, what makes this study notable is the thoroughness with which the subjects’ aspartame intake was assessed.
“Every two years, participants were given a detailed dietary questionnaire, and their diets were reassessed every four years. Previous studies which found no link to cancer only ever assessed participants’ aspartame intake at one point in time, which could be a major weakness affecting their accuracy.
