Coffee is the beverage of choice for millions around the world. The cafe is an almost an entirely North American and European trend. In areas of the Middle East, Africa, South America and Asia, coffee is seen as something more akin to cigarettes, and is drunk while socializing or doing other things, rather than being and end unto itself. Now in China, more and more people are delighted by the special flavor of coffee.
Aside from tasting good (and smelling even better), coffee is believed to have a number of health benefits. According to research funded by the American Cocoa Research Institute, coffee drinkers appear to have higher levels of antioxidants than those who don't drink the beverage. Antioxidants help the body ward off harmful free radicals, which can damage cells and DNA. Studies have shown antioxidants to have a number of other health benefits, including protection against heart disease. Statistics from Harvard Health Publications say that coffee may reduce the risk of developing gallstones, discourage the development of colon cancer, improve cognitive functions, reduce the risk of liver damage in people at high risk for liver disease, and reduce the risk of Parkinson's disease. Coffee has also been shown to improve endurance performance in long-duration physical activities.
