Aspartame Safety And Evidence

All artificial sweeteners are firmly regulated and can only be used after they have been assessed rigorously for their safety. Aspartame is a common artificial sweetener constitutes of amino acids, aspartic acid and phenylalanine. Aspartame has low calories and is approximately 200 times sweeter than sugar, so even very small amounts of it can be used without contributing to any calories to the body.


Aspartame is used throughout the world along with cereals, as table-top sweeteners, in low-calorie soft drinks, sugar-free chewing gum, sugar free and vitamin cough drops, yogurt, and various other food items.

Safety and Evidence

Aspartame has numerous rumors surrounding it, all claiming that it causes health problems. There are, however, almost 200 studies available on aspartame safety conducted by organizations like the Joint Expert Committee on Food Additives (JECFA) of the World Health Organization, the Scientific Committee on Food (SCF) of the European Union, the Food and Drug Administration (FDA), and Food and Agriculture Organization, and some regulatory agencies all over the world. These have found that aspartame is safe for use at the present Acceptable daily intake (ADI) of 40 mg per kilogram of body weight.

In adults

Research studies have been conducted on the impacts of aspartame on behavioral changes in adults. Ryan-Harshman tested healthy adult men who were given a high dose of aspartame; no evidence of any behavioral or neuropsychologic effects on the adults were found. Follow-up studies of high-dose aspartame given to both male and female college students also found no changes in their behaviors.

In children

In the USA, a team of researchers conducted trials on the effects of aspartame on children. This study also showed no effects of aspartame on behavioral and cognitive changes in children.
