Health Benefits of Coffee

– Numerous studies have shown that even small amounts of caffeine significantly improve concentration, mental endurance and reflex speed. Subjects did not know whether they were being given caffeine or a placebo (a beverage that looked and tasted exactly like coffee, but contained no caffeine). Results were conclusive: the performance of subjects who were given a placebo was markedly inferior to that of subjects who had received caffeine. To confirm these findings, Dr. J. Wurtman compared people who were used to drinking coffee with persons who never drank coffee. The results were identical. On the other hand he suggested that coffee’s effect on neurons, as well as the effects of benzopyrene, a carcinogenic substance produced during roasting of coffee beans, should be taken into account when deciding how much coffee an individual should drink.
