    • Coffee and tea are the primary sources of dietary caffeine.
    • Understanding caffeine consumption patterns is crucial for public health.

    Purpose of the Study:

    • To detail the production, trade, and consumption of caffeine.
    • To focus on caffeine derived from coffee and its global significance.
    • To provide an overview of worldwide caffeine intake in 1981.

    Main Methods:

    • Analysis of global caffeine production data.
    • Examination of trade statistics for caffeine-containing products.
    • Estimation of worldwide and per capita caffeine consumption.

    Main Results:

    • Coffee accounts for approximately 54% of total caffeine consumption.
    • Tea contributes about 43% to global caffeine intake.
    • World caffeine consumption in 1981 was estimated at 120,000 tonnes (70 mg/person/day).

    Conclusions:

    • Caffeine consumption varies significantly worldwide.
    • North American per capita caffeine intake is triple the global average.
    • Heavy coffee and tea consumption countries show much higher per capita rates.
