Using epidemiology to regulate food additives: saccharin case-control studies.

F Cordle, S A Miller

    Public Health Reports (Washington, D.C. : 1974)
    |July 1, 1984
    PubMed
    Summary

    High doses of the artificial sweetener saccharin have been shown to cause bladder cancer in rodents. This led to regulatory reviews and human epidemiologic studies to assess potential risks.

    Area of Science:

    • Toxicology
    • Carcinogenesis
    • Food Safety

    Background:

    • Nonnutritive sweetener use increased, prompting safety investigations.
    • Rodent studies indicated saccharin's carcinogenic potential, specifically bladder tumors.
    • The 1969 cyclamate ban heightened scrutiny of artificial sweeteners.

    Purpose of the Study:

    • To assess the carcinogenic potential of saccharin in rodents.
    • To evaluate the human health risks associated with saccharin consumption.
    • To review available human epidemiologic data on saccharin and bladder cancer.

    Main Methods:

    • Long-term rodent feeding studies were conducted.
    • Analysis of collective experimental evidence on saccharin's effects.
    • Assessment of human epidemiologic studies, including recent data.

    Main Results:

    • High doses of saccharin induced bladder cancer in rodents.
    • Regulatory bodies considered banning saccharin based on rodent data.
    • Epidemiologic studies were initiated to determine human risk.

    Conclusions:

    • Rodent studies provided evidence for saccharin's carcinogenicity.
    • The Delaney Clause mandated safety evaluations for food additives.
    • Human epidemiologic data were crucial for assessing real-world risk.
