The longest running study ever on the popular sweetener aspartame shows terrible results in humans. This study is the most comprehensive, long-term study ever completed on aspartame and included 77,218 women and 47,810 men in its analysis.
The results of this study showed that just one twelve-ounce can of aspartame-containing 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 risk (in men only)
It is not known why only men receiving higher amounts of aspartame-containing diet soda increased risk for multiple myeloma and non-Hodgkin lymphoma. It is interesting to note that diet soft drinks represent the single largest source of aspartame in the United States by totaling 86 percent of aspartame consumption.
A previous best-in-class research study conducted on animals (900 rats over their entire natural lifetimes) showed strikingly similar results in 2006. In that study, aspartame consumption significantly increased the risk for lymphomas and leukemia in both males and females.
More worrisome is the follow-up study, which started aspartame consumption in the rats at their fetal stage. This increased lymphoma and leukemia in addition to causing the female rats significantly increased breast (mammary) cancer rates. Since aspartame has been implicated in other cancers such as brain and prostate, it is possible future studies will confirm those links as well.
With other safe sweeteners on the market such as Xylitol and Stevia, that actually have health benefits to us rather than dangers, we have no excuse to continue using aspartame. You’d be better off to simply drink something sweetened with regular cane sugar.
