Aspartame – is Safe

Looking at more than 500 reports, including toxicological, clinical and epidemiological studies dating from 1970’s preclinical work to the latest studies on the high-intensity sweetener, along with use levels and regulations data, an international expert panel from 10 universities and medical schools evaluated the safety of aspartame for people of all ages and with a variety of health conditions.

A non-nutritive sweetener, aspartame is approximately 200 times sweeter than sucrose, the accepted standard for sweetness. Though aspartame has the same number of calories as sugar on a weight-to-weight basis, it can be added to food or pharmaceuticals at a fraction of what would be needed with sucrose to achieve the same sweetness, with far fewer calories.

The team reviewed studies that tested a number of health effects of varying levels of aspartame, including amounts that far exceed the acceptable daily intake, on animals and humans. In addition to healthy adults and children, studies also looked at effects on adults and children with diabetes, hyperactive and sugar-sensitive children, and people with Parkinson’s disease and depression.
The Expert Panel’s evaluation concluded the following:
• Aspartame is safe at current levels of consumption, which remain well below established ADI levels, even among high user sub-populations. No credible evidence was found that aspartame is carcinogenic, neurotoxic or has or any other adverse effects when consumed even at levels many times the established ADI levels.
• Based on results of several long term studies, aspartame does not have carcinogenic or cancer-promoting activity.
• Results of extensive investigation in studies that mimic human exposure do not show any evidence of neurological effects, such as memory and learning problems, of aspartame consumption.
• Overall the weight of the evidence indicates that aspartame has no effect on behavior, cognitive function, neural function or seizures in any of the groups studied.
• Aspartame has not been shown to have adverse effects on reproductive activity or lactation.
• Studies conclude that aspartame is safe for use by diabetics and may aid diabetics in adhering to a sugar-free diet.
• There is no evidence to support an association between aspartame consumption and obesity. On the contrary, when used in multidisciplinary weight control programs, aspartame may actually aid in long-term weight control.
• The studies provide no evidence to support an association between aspartame and brain or hematopoietic tumor development.
