Natural toxicants in foods.

J M Coon

    Journal of the American Dietetic Association
    |September 1, 1975
    PubMed
    Summary

    Naturally occurring food toxicants like goitrogens and estrogens pose minimal risk due to low concentrations and interactions. Major food hazards stem from contaminants, excessive intake, or improper food handling, not inherent food toxicity.

    Area of Science:

    • Food toxicology
    • Chemical ecology
    • Nutritional science

    Background:

    • Food is a complex chemical environment containing naturally occurring toxicants.
    • Substances like goitrogens and estrogens are present in food but typically pose slight hazards.

    Purpose of the Study:

    • To differentiate between toxicity and hazard in the context of food toxicants.
    • To identify the primary sources of food-related hazards for human health.

    Main Methods:

    • Review of existing toxicological and nutritional data.
    • Analysis of factors influencing the hazard posed by naturally occurring food substances.
    • Evaluation of common food consumption patterns and handling practices.

    Main Results:

    • Naturally occurring toxicants in food are generally present in low concentrations.
    • Antagonistic interactions between different toxicants can reduce overall risk ('safety in numbers').
    • Significant food hazards are more commonly linked to contaminants, excessive consumption, or poor dietary habits.

    Conclusions:

    • The inherent toxicity of natural food components is usually outweighed by low concentrations and synergistic effects.
    • Practical hazards from food are predominantly associated with external factors like contamination, overeating, and unbalanced diets.
