Research Question: What Are the Health Effects of Coffee?
Slide 3
Introduction: Coffee is a controversial stimulant Its important
to know what effects coffee has on our health Annual Worldwide
Consumption of Coffee Exceeds 4 Million Tons
Slide 4
Article #1 coffee+mental stress task Caffeine-nave vs.
Caffeine- habituated females They were given normal cup of coffee
and HR, BP, and mental alertness were monitored Used a word fluency
test
Slide 5
The combined Effect of coffee and Mental stress task.
Caffeine-Nave Caffeine- habituated Blood Pressure SBP and DBP SBP
and DBP Heart Rate Mental Alertness Article #1 Results
Slide 6
Article #2 Caffeine and Progression of Dementia Two groups were
formed, each group consisting of individuals that were normal, MCI,
and those who already have dementia One group received doses of
caffeine below the critical level of daily caffeine intake and the
other received doses of caffeine above the critical level
Slide 7
Article #2 Results The results of the study concluded that the
subjects who were MIC at the beginning of the study and received
the above critical level amount of caffeine as treatment had a
lower rate of the onset of dementia than any other subjects in the
study.
Slide 8
Article #3 Endothelial Function researchers investigated the
acute effects of caffeine and antioxidants on endothelial function
measured by brachial artery flow-mediated dilation (FMD) Two groups
formed with caffeinated and decaffeinated coffee (130mg and 5mg of
caffeine respectively)
Slide 9
Article #3 Researchers came to the conclusion that both
systolic and diastolic blood pressure were higher in the CC group,
FMD decreased in CC group. There was no difference in glucose
concentration in either group. In conclusion the authors discussed
that CC may have acute unfavorable cardiovascular effects in
healthy subjects.
Slide 10
Article #4 Caffeinated and Decaffeinated coffee Tested
somnolence Two groups Caffeinated and Decaffeinated coffee
(130mg/5mg respectively
Slide 11
Article #4 Results The results concluded that consumption of CC
adversely effected somnolence. The deactivation of sleepiness in
turn stimulated subjective activation in participants. DC also
produced a decrease in somnolence and an increase in activation
evaluations
Slide 12
Article #5 Adolescents Study included adolescents of Iceland
from ages 13-15 Surveys were administered to assess the
relationship between adolescents, their consumption of caffeinated
substances and the effect it has on their sleep patterns and their
behavior
Slide 13
Article #5 Results The results indicated that the use of
caffeine was only moderately related to sleepiness, They also
indicated that there is strong inverse correlation related to
academic achievement
Slide 14
Conclusions More research needed The Caffeine in coffee raises
BP, and decreases HR Moderation is important Coffee could be
effective against the development of dementia Coffee may have acute
unfavorable cardiovascular effects in healthy subjects.
