Research Question: What Are the Health Effects of Coffee?
Introduction: • Coffee is a controversial stimulant • It’s important to know what effects coffee has on our health • Annual Worldwide Consumption of Coffee Exceeds 4 Million Tons
Article #1 coffee+mental stress task • Caffeine-naïve vs. Caffeine-habituated females • They were given normal cup of coffee and HR, BP, and mental alertness were monitored • Used a word fluency test
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
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.
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)
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.
Article #4 Caffeinated and Decaffeinated coffee • Tested somnolence • Two groups Caffeinated and Decaffeinated coffee (130mg/5mg respectively
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
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
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
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.
