Aspartame is one of the most thoroughly studied food ingredients in the world. Permitted for use in more than 100 countries worldwide, it is found in hundreds of products ranging from chewing gum to toothpaste and table top sweeteners like Equal®.
Aspartame is made up of two naturally occurring amino acids, which yield 4 calories per gram, which means that technically it is a caloric sweetener. However, because it is nearly 200 times sweeter than sugar, a mere 190 milligrams (190 milligrams ~1 calorie) of aspartame has the same sweetening power as almost 40 grams (160 calories) of sugar.
The safety of aspartame was reaffirmed in Dec. 2013 by the European Food Safety Authority (EFSA) following a comprehensive assessement of aspartame safety undertaken to address consumer concerns. The National Cancer Institute (NCI) and an independent international expert review panel have also confirmed that aspartame does not cause cancer, seizures or other health problems.In addition, an evidence-based research review by the Academy of Nutrition and Dietetics confirms aspartame does not increase in appetite or food intake.
