If you look around, there are probably many
coffeehouses near you. Coffee is big, big business.
According to the International Coffee Organization, the
world drinks about $70 billion in coffee each year.
Although coffee is one of the world’s most popular
drinks, many people believe it isn’t healthy. It has been
blamed for high heart rates, high blood pressure, and
stomach problems. Coffee can make you feel more stress
and it can result in sleep problems. Medical research,
however, has started suggesting that coffee might
actually be good for us. In addition to giving us energy
and keeping us alert, coffee is thought to be helpful for
headaches. As coffee also contains antioxidants, it can
protect our bodies against harmful substances in things
like smoke and pollution. Recent studies have found that
coffee helps to prevent certain types of cancer. One
study in Tokyo, for example, discovered that coffee
drinkers were half as likely as nondrinkers to have liver
cancer. Overall, the research shows that coffee is far
more healthful than it is harmful.
