1977: Saccharin banned as a food additive
• One teaspoon of sugar contains 16 calories; there are no calories in saccharin, which is at least 200 times sweeter than sugar.
• The name saccharin comes from the Latin saccharum, which means sugar.
• The saccharin ban in Canada remains in effect today. Though there was no comparable sugar substitute at the time of the ban, several later entered the market: aspartame (also known as NutraSweet), sucralose (Splenda), and the natural herb stevia, a relatively new alternative.
• In the United States, a ban was proposed by the Food and Drug Administration in 1977, but Congress placed a moratorium on the ban, citing consumer demand. However, products using saccharin were obliged to carry a label warning that the substance had caused cancer in lab rats. In 2000, saccharin was removed from the U.S. government's list of carcinogens, and the warning labels were no longer required.
• According to the study that prompted the ban, a human would have to consume the equivalent of 800 cans of diet drinks a day to risk getting cancer from saccharin. Subsequent studies have also shown that there is a minimal risk of cancer associated with saccharin consumption.
