"Recent studies have shown that coffee consumption in moderation can potentially have a number of health benefits"



Worldwide, we drink more than 400 billion cups of coffee a year! Finland tops the charts with, on average, five cups a day. Germany and Japan come in a close second and third. So, the question needs to be asked: Is coffee harmful?

"It can be an important part of a healthy lifestyle."

Recent studies have shown that coffee consumption in moderation can potentially have a number of health benefits because coffee contains anti-oxidants.

"An anti-oxidant is simply a naturally occurring chemical that fights the damaging effects of oxygen in the body, and the compounds in a coffee are called poly-phenols. These are found in many fruits and fruit juices, and they're also found in coffee because, of course, coffee comes from the coffee bean, which is then roasted and releases many of these compounds."

But the ingredient most coffee drinkers are interested in is the addictive stimulant, caffeine.

"This typical cup of coffee would have about the amount of caffeine that would fill up about one quarter of this teaspoon."

That's about 150 milligrams.

Caffeine changes the brain's chemistry. It blocks the action of the chemical adenosine, that's associated with sleep, which is why after a coffee, a person feels more awake.

Caffeine activates the brain's pleasure center, which contributes to caffeine addiction, and it also triggers the sympathetic nervous system, setting off the fight or flight response. This stimulation injects adrenaline into your system making you more alert and responsive.
