Can I have coffee on an empty stomach? Coffee contains caffeine, which has a strong bitter taste and stimulates the central nervous system, heart and respiratory system. Therefore, the right amount of caffeine can reduce muscle fatigue, promote digestive juice secretion, have diuretic effect, and help the body to expel excess sodium ions from the body.

Coffee contains caffeine, tannic acid, fat sugars, etc., in which the stimulating effect of caffeine can play the refreshing effect of coffee. There used to be classmates around me who couldn't get rid of sleepy classes in the morning, so they often drank coffee on an empty stomach. Since coffee is stimulating, does it make people think that drinking coffee on an empty stomach is harmful to people? What effect will it have on our health?

First of all, coffee will stimulate gastric acid secretion, and even if it is not drunk on an empty stomach, it will also be irritating to the stomach. Therefore, drinking coffee that is already irritating on an empty stomach can easily cause "stomach gas injury", thus affecting the digestion and absorption of gastric function. Serious cases can lead to gastric ulcers, and patients with gastric ulcers should pay more attention not to drink coffee on an empty stomach.

Secondly, coffee is rich in sugar and energy. Drinking coffee on an empty stomach not only hurts the stomach, but also tends to get fat.

Generally speaking, coffee should not be drunk on an empty stomach, preferably after a period of breakfast and lunch, or between meals, because this can not only promote gastrointestinal peristalsis and help digestion, but also decompose high-calorie and high-fat foods that have just been eaten. It won't irritate the intestines and stomach. But do not drink coffee immediately after a meal or drink coffee while eating, which will affect the gastrointestinal absorption of minerals and other nutrients in the food.
