Acceptable daily intake vs actual intake: the aspartame example

Area of Science:

• Food Science
• Toxicology
• Regulatory Affairs

Background:

• The acceptable daily intake (ADI) is a critical metric for assessing food additive safety.
• Postmarketing surveillance of consumption levels is essential for verifying safety in real-world scenarios.
• Aspartame (APM) is a widely used artificial sweetener with established ADI values by major regulatory bodies.

Purpose of the Study:

• To evaluate the safety of aspartame (APM) by comparing its consumption levels with its ADI.
• To discuss the implications of ADI and actual consumption for food additive safety.
• To review methods for measuring food additive consumption.

Main Methods:

• Review of regulatory ADI values for aspartame (APM) from WHO, Europe, Canada, and the US FDA.
• Analysis of consumption data for aspartame (APM) using food intake surveys.
• Comparison of estimated APM consumption levels with established ADI values across different populations and countries.

Main Results:

• Aspartame (APM) has an ADI of 40 mg/kg/day (WHO, Europe, Canada) or 50 mg/kg/day (US FDA).
• Food intake surveys in the US, Canada, Germany, and Finland show APM consumption is approximately 2-10 mg/kg/day.
• Estimated APM consumption is significantly below the ADI for all age groups and subpopulations, even at the 90th percentile.

Conclusions:

• Current consumption levels of aspartame (APM) are well within the safe limits defined by its ADI.
• Postmarketing surveillance data supports the safety of aspartame (APM) at typical consumption rates.
• The methodologies used provide reliable estimations for assessing food additive safety in populations.
