Is it true that coffee shouldn’t be drunk on an empty stomach?

Have you ever had coffee right away after waking up on an empty stomach? Did you know that drinking coffee on an empty stomach can harm your health? This time, ACU PAY will tell you why we should not drink coffee on an empty stomach and how to drink coffee safely for our health.


Is it true that coffee shouldn't be drunk on an empty stomach?

One thing that many people are craving instantly when they wake up is ‘Coffee’ because the caffeine will make them feel refreshed, energetic, and wide-awaked. However, drinking coffee on an empty stomach can harm oneself.

How does drinking coffee on an empty stomach affect our body?

  • Stimulate acid in the stomach

Coffee contains caffeine and other mild acidic ingredients. When drinking coffee on an empty stomach, these acids stimulate gastric acid secretion. 

When such acid occurs too much, it causes irritation, burning sensation, flatulence, and indigestion, leading to acid reflux, gastric lesions or irritable bowel syndrome, and chronic acid reflux. These may increase the risk of esophageal cancer.

  • Blood sugar may soar

According to a June 2020 journal study in the British Journal of Nutrition, drinking black coffee on an empty stomach reduces blood glucose control. On the other hand, people who eat breakfast before drinking coffee do not experience a rise in blood sugar.

  • Dehydrate the body

Caffeine in coffee has a diuretic effect, meaning the body loses more water through the urine. Drinking coffee on an empty stomach, especially in the morning when your body does not get enough water, results in dehydration, fatigue, headaches, dizziness, and heart trembles.

  • Disturb the absorption of nutrients

Coffee contains tannins that can bind to certain minerals, such as iron, calcium, and magnesium. If you drink coffee on an empty stomach, these tannins will interfere with the absorption of these minerals from food. As a result, the body lacks the minerals needed for various functions.

  • More anxiety

Did you know that drinking coffee instead of breakfast reduces the brain’s ability to release serotonin which helps control the mood? If you drink coffee, you increase cortisol, causing stress and excitement in your body, causing some people to get stressed, anxious, and nervous.

What is the best time to drink coffee?

The best time to drink coffee is at least 30 minutes after breakfast. If you want to be alert, you should drink coffee between 9:30 and 11:30 p.m. because the cortisol level starts to drop. The body is sensitive to caffeine, making you feel alert and focused.

According to the University of Michigan Medicine, your energy-enhancing cortisol levels peak around 7:00 a.m. The reason why cortisol levels are high in the morning is that the body needs to be alert, prepared for various activities and to balance blood sugar.

If you would like to drink coffee in the afternoon, you should drink it before 4 p.m. so that it doesn’t affect your sleep.

Therefore, you should avoid drinking coffee on an empty stomach. You should eat food or milk at least 30 minutes before drinking coffee. If you want to drink coffee in the morning, it is recommended to have breakfast or yogurt, bread, and fruit to reduce stomach irritation. The best coffee is black coffee with no sugar or cream.
