Apart from oil, coffee is the oldest and most traded commodity in the world. In western countries, people hurrying to work with a cup of coffee can be seen everywhere on the street in the early morning. Starbucks chain stores have sprung up everywhere in China, and even many old people can recognize its "banshee" logo at a glance. According to the statistics of the International Coffee Organization, the annual consumption of coffee in the world is 400 billion cups. Every second, 14000 cups of coffee are drunk in the world. Coffee has become the second largest drink in the world after water. Finns are among the world's top coffee drinkers, with a per capita coffee consumption of 12 kilograms in 2008. Even in some tea culture countries in Asia, coffee is becoming more and more popular, and Japan has replaced Germany as the world's second largest consumer of coffee. In the United States, more than half of people drink coffee every day, and nearly 90 percent must have coffee for breakfast. In contrast, although coffee is "well-known" in China, its "acceptance" is not high. According to the survey, the average Chinese consume less than 100 cups of coffee per person per year. Among coffee drinkers, 56% are men and 44% are women. Among them, the largest number of people aged 41 to 50, accounting for 24%, followed by those aged 21 to 30, accounting for 18%.

Ennis Doyli, one of the founders of the Coffee Scientific Information Society, pointed out that there were many misunderstandings about coffee in the past, and it was only after a number of experiments conducted by a group of scientists over the past decade that people gradually redefined coffee as a healthy drink. It is increasingly found that coffee contains not only caffeine, but also protein, fat, nicotinic acid, tannic acid, alkaloids, potassium, dietary fiber and other nutrients. Precisely these nutrients define coffee as a healthy drink.
