in various forms of foodstuff. This study aimed to investigate caffeine intake
and knowledge concerning caffeine health effects in a community of Thailand,
Nakhonnayok province. A questionnaire was used to survey how people consumed
caffeine-containing foodstuff daily. Urine caffeine concentrations analyzed
by GC/NPD method were used to estimate how much caffeine has been consumed in
this community based. The study showed that there were a large number of people
in this population who did not know if caffeine had health effects and some
did not know if caffeine could be found in foods other than coffee and tea.
Coffee was an important dietary source of caffeine for this population. No significant
correlation of gender and age of the respondents on types of daily beverage
intake were found. Urine caffeine concentrations were found up to 9,482 ng/mL.
This maximum concentration was quite high which indicated that some had daily
ingested large amount of caffeine containing foodstuffs. Thus, the education
program is needed for the studied community in order to prevent future excessive
caffeine consumption unintentionally.
