Caffeine in beverages: Cardiovascular effects

Caffeine is one of the neuroactive substances most prevalent in western countries. Its cardiovascular effects are well known, as well as different cardiovascular responses were observed in individuals who usually take caffeine-containing beverages and foods regularly than those who take it occasionally. The hypothesis that coffee consumption would lower the risk of cardiovascular disease has been suggested by recent studies. This association is partially mediated by bioactive substances contained in coffee. In recent years there have been widespread use of, especially among young people, beverages called “Energy Drinks” which contain a much higher amount of caffeine. The chapter will explore the cardiovascular effects of caffeine and caffeinated beverages.
