Nowadays, many people drink decaffeinated coffee to avoid consuming too much coffee. American scientists point out that decaffeinated coffee is usually made from high-fat coffee bean Robusta, instead of traditional coffee bean Arabica, because the former has a stronger coffee flavor. However, drinking this caffeine-free coffee for a long time will increase the cholesterol level in people's blood, which is not conducive to heart health care.

Robert Saboko of the Piermont-Messer Health Center in Atlanta, USA and his colleagues conducted an experiment on 187 people. The experiment was divided into three groups for 3 months. Among them, one group drank 3-6 cups of decaffeinated coffee every day, one group drank 3-6 cups of caffeinated coffee every day, and the third group did not drink coffee as a control.

The researchers found that the concentration of nonesterified fatty acids (NEFAs) in the blood of the decaffeinated coffee group was 65,438+08% higher, and the concentration of apolipoprotein B was 8% higher. While the other two groups did not rise. Apolipoprotein B is related to cholesterol and can cause cardiovascular diseases.

"Caffeine-free coffee is more harmful to heart health than regular coffee," Saboko said. If adding a small amount of fat is not a big problem, people can burn them by increasing exercise, but the risk of high cholesterol should be considered. It is suggested that people who drink more than 4 to 5 cups of decaffeinated coffee every day should pay attention to reducing the number of drinks. "
