If you look around, there are probably many coffeehouses (咖啡馆) near you. Coffee is a very 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 stressed and it can lead to sleep problems. Don’t even think about drinking coffee before you go to bed, or you’ll be up all night! One common belief is that some women who drink coffee may have a hard time getting pregnant (怀孕). Others believe coffee can cause low birth weight if pregnant women drink it. Medical research, however, has started suggesting that coffee might actually be good for us. It can give us energy, and it is thought to be helpful for headaches. It can protect our bodies against harmful substances in things like smoke and pollution. Overall, research shows that coffee is far more healthful than harmful. While coffee may have health benefits, it is also full of caffeine which can make us feel excited. However, the problems can be controlled by limiting the amount of coffee we drink. There is no evidence that coffee is more truly harmful, and every day there is more evidence to show that it is good for us.
