  „Among other age groups, the study also uncovered an increase of out-of-home consumption, a shift from recent trending toward in-home consumption.

  „Insomnia and even twitching muscles and diarrhea may be among the effects. Very large doses of caffeine, the equivalent of about ten cups of strong coffee drunk in a row, produce toxic effects: vomiting, fever, chills, and mental confusion. In enormous doses caffeine is, quite literally, deadly. The lethal dose of caffeine in humans is estimated at about ten grams, or the equivalent of consuming 100 cups of coffee in one sitting.“

For example, there is growing evidence that caffeine intake from coffee can increase alertness in car drivers and hence reduce accidents.

Coffee: Old Familiar Becomes New Favorite

  „Despite years of speculation and research, scientists have not been able to link normal levels of caffeine intake to major chronic diseases like heart disease or cancer. The most common and well-defined effect of coffee stems from its role as a central nervous system stimulant. Within 30 to 60 minutes of drinking coffee, caffeine levels peak to produce alertness and heightened concentration. While some people do well with this boost, others become over-stimulated; side effects include insomnia, anxiety, irritability and diarrhea.“

Less calories and less caffeine usually means a reduction in energy which could lead to binge eating.“
