Drinking black coffee can relax the bowels and clear the intestines, because it contains a lot of vitamins, amino acids, cholesterol and other beneficial ingredients, which can help the food in the digestive tract, promote the peristalsis of the intestine and help the body discharge waste. In addition, black coffee also contains a certain amount of water: when you feel dehydrated in the morning or after exercise, it can also replenish the water that your body lacks. And because it does not contain too much sugar, creamer or other additives, it is a good choice for people who want to protect their stomachs from harm. In short, drinking some original black coffee properly is a good way to help the body defecate normally and clean the intestines.
