Coffee is healthy. Coffee can also keep healthy.

Coffee is the most popular drink in the world. People like coffee more and more, whether at home or in the office, people drink coffee is a kind of feeling, is a kind of fashion, is a kind of leisure, is a kind of culture. But have you ever heard that coffee can also keep you healthy?

In Australia, tests on track and field athletes who consumed a small amount of caffeine showed that they could afford to train 30% longer than those who had not had coffee. The score is also 36% higher than usual.

The body's preferred source of energy during exercise is usually carbohydrates stored in the liver in the form of glycogen. Only after carbohydrate reserves are depleted (usually requiring more than 60 minutes of continuous aerobic exercise). Fat becomes a source of energy through metabolism, resulting in weight loss. However, researchers at the Australian Institute of exercise in Canberra found that caffeine contains substances that allow muscles to directly consume fat instead of normal carbohydrates during exercise.

The role of caffeine in promoting fat metabolism has been discovered by scientists studying sports performance. They found that cyclists who drank mild cola or coffee during the race rode faster and farther than those who drank water.

Jane Griffin, a sports nutritionist and adviser to the British Olympic sports delegation, said the findings could be important for everyone who exercises regularly. "A cup of coffee or cola absorbed by the body can quickly promote the dissolution of fat into the bloodstream, allowing the body to use fat as the main source of energy before converting its limited carbohydrate reserves into energy," she said.
