Knowledge Gained from Research about each of these sweeteners: Studies to understand the harmful effects of artificial sweeteners started there can be a possible nexus between cyclamate sweeteners and bladder cancer in particular. But to date no such association is firmly established in human beings.


About Saccharin:Ai??Studies on this sweetener started in the 1970s. Laboratory experiments conducted on male rats with this sweetener proved that it may cause bladder cancer in rats. When further studies were carried out in humans in the later years, no such evidence was found. In the year 2000, this sweetener was delisted from the cancer causing substances lists.

About Aspartame:Ai??It got approved by the government for the first time in the year 1981. When its status was reviewed in 1996, it was doubted that this sweetener was responsible for an increase in brain tumors between 1975 and 1992 in United States. Again in the year 2005, laboratory research claimed to have established a link between this sweetener and blood cancer. But the links never got clearly established.

About Cyclamate:Ai??It was banned in the year 1969 by the FDA. Later studies proved the substance to not be responsible for spreading cancer. It is still in the news as there are petitions filed against it with the FDA. However, these cases are not active anymore.

Sucralose, Neotame, Acesulfame potassium are the sweetners which got clean chit from the government of not being cancer causing agents in recent times. More than 100 safty studies were carried on each of these sweetners and their role in cancer was closely monitored before they were allowed to be sold in the market.

  1. I have always stayed away from aspartame, in particular because I have a variant of Phenylketonuria (you may have seen the warnings for phenylketonurics on labels where aspartame is listed).

  2. i thought aspartame can cause cancer in laboratory animals .
