Chemical Composition and Discovery:
- Aspartame is a methyl ester of the dipeptide of two natural amino acids, L-aspartic acid and L-phenylalanine.
- It was discovered by James M Schlatter, a chemist at the American pharmaceutical company G D Searle & Co., in 1965.
- Schlatter accidentally detected its sweet taste when he licked his finger during research on an anti-ulcer drug.
Sweetness and Caloric Content:
- Aspartame is approximately 200 times sweeter than table sugar (sucrose) according to the US Food and Drug Administration (FDA).
- Compared to sugar, 1 gram of aspartame has the sweetness intensity of approximately 2 teaspoons (8 grams) of sugar.
- Aspartame is preferred by people looking to reduce calorie intake or manage weight, as 1 gram of aspartame provides only 4 calories, while 2 teaspoons (8 grams) of sugar provide about 32 calories.
Use in Food and Beverages:
- Aspartame is present in various brands of artificial sweeteners, such as Equal and Sugar-Free Gold, and is commonly used in diet fizzy drinks.
- Diet beverages containing aspartame often promote themselves as having “zero sugar” or “zero calories.”
Safety and Regulation:
- Aspartame has undergone extensive scientific studies and testing for over 40 years, including investigations into its potential links with cancer.
- More than 100 studies have found no evidence of harm caused by aspartame.
- The safety of aspartame is widely accepted by regulatory authorities, including the USFDA, EFSA, WHO’s JECFA, and national regulators in several countries.
- The only group advised to avoid aspartame is individuals with phenylketonuria (PKU), a rare inherited disorder that affects the metabolism of phenylalanine.
Public Perception and Controversy:
- Some critics and studies have raised doubts and concerns about aspartame, but there is a broad scientific consensus on its safety.
- The International Agency for Research on Cancer (IARC) has classified aspartame as “possibly carcinogenic to humans” based on limited evidence, but this classification has been disputed.
- Past IARC rulings have raised consumer concerns, led to lawsuits, and influenced product formulations.
