The main difference between decaffeinated coffee and regular coffee lies in the caffeine content. Coffee without cause contains no caffeine, while regular coffee contains caffeine. At present, coffee without cause is common in foreign countries, but rare in China.
American scientists point out that decaffeinated coffee is usually made from Robusta beans with high fat content, rather than traditional Arabica beans. Drinking this caffeine-free coffee for a long time may lead to an increase in blood cholesterol levels, which is not conducive to heart health. Therefore, if you drink coffee for no reason, you should choose carefully and pay attention to moderate drinking.
