Drinking black coffee on an empty stomach in the morning: Is it bad for your health?

introduction

Drinking black coffee on an empty stomach in the morning is a daily habit for many people. It is believed to refresh the mind and increase energy. However, some studies have shown that drinking black coffee on an empty stomach may be harmful to the body. This article will explore the effects of drinking black coffee on an empty stomach in the morning and analyze its potential risks to physical health.

Effects of Caffeine

First, we need to understand the effects of caffeine on the body. Caffeine is a central nervous system stimulant that promotes the release of neurotransmitters such as dopamine and norepinephrine in the brain. This leads to the effects of American coffee such as refreshing, increased alertness and improved concentration.

Possible problems with drinking black coffee on an empty stomach

However, drinking black coffee on an empty stomach may cause a series of problems. First, since there is no food to buffer the stomach acid, the high concentration of stomach acid will directly contact the stomach wall, which may cause problems such as stomach pain, indigestion, and stomach ulcers.

Secondly, drinking coffee on an empty stomach may stimulate intestinal peristalsis and increase the frequency of bowel movements. This may be a good thing for some people, but for those who already have gastrointestinal problems, it may cause diarrhea or aggravate symptoms.

In addition, drinking coffee on an empty stomach may also affect blood sugar levels. Caffeine can promote the release of adrenaline and inhibit the secretion of insulin. This causes blood sugar to rise and then fall rapidly after a period of time. For people who already have problems with blood sugar control, such drastic blood sugar fluctuations may be unfavorable.

Other potential risks

In addition to the direct effects mentioned above, there are other potential risks in drinking black coffee on an empty stomach in the morning. The first is problems with the cardiovascular system. Excessive intake of caffeine can cause increased heart rate, increased systolic blood pressure, and arrhythmia, which may increase the risk of cardiovascular events (such as angina pectoris and myocardial infarction) during long-term use.

Secondly, caffeine has a certain impact on sleep quality. Although drinking coffee in the morning can refresh the mind, long-term use may lead to insomnia and poor sleep quality. This will further affect the health of the body and daily life.

Recommendations for moderate drinking

Although there may be some risks associated with drinking black coffee on an empty stomach, moderate consumption is unlikely to cause significant harm to most people. According to the American College of Nutrition, consuming less than 400 mg of caffeine per day (about four 8-ounce cups) is relatively safe.

In addition, it is best to eat something before drinking black coffee on an empty stomach to buffer stomach acid and reduce stomach discomfort. It is also a good idea to choose low-concentration or decaffeinated coffee to reduce the intake of excessive stimulants.

in conclusion

In summary, drinking black coffee on an empty stomach in the morning may be harmful to your body. It may cause stomach discomfort, intestinal problems, and blood sugar fluctuations, and may increase the risk of cardiovascular events and poor sleep quality. However, drinking in moderation and eating something before fasting can reduce these potential risks. If you have any health problems or concerns, please consult your doctor for advice.
