After breakfast or on an empty stomach? The truth behind black coffee's ability to reduce swelling is revealed!

A cup of fragrant black coffee in the morning is a must-have for many people to start a new day. However, there has always been controversy about whether drinking coffee after breakfast or on an empty stomach has any effect on health. This article will explore this topic from a scientific perspective.

Gastric acid secretion and food intake timing

First, we need to understand the relationship between gastric acid secretion and food intake time. The production and secretion of gastric juice in the stomach is mainly completed by two types of cells: parietal cells and chief cells. Parietal cells are responsible for producing hydrochloric acid and mucus, while chief cells are responsible for producing digestive enzymes.

When we eat, our nervous system sends signals to the parietal cells, prompting them to release hydrochloric acid and mucus. These substances help digest food and provide a protective barrier against invading pathogens.

However, drinking coffee on an empty stomach may stimulate the parietal cells to secrete more hydrochloric acid, leading to excessive gastric acid, which may cause a series of problems such as heartburn, indigestion, and reflux esophagitis.

Benefits of drinking coffee after breakfast

In contrast, drinking coffee after breakfast may be more appropriate. When we eat, food can act as a buffer and reduce irritation to the gastric mucosa. In addition, food intake can dilute the concentration of hydrochloric acid and provide a protective barrier.

Another benefit is that consuming caffeine in the morning can boost alertness, increase consciousness, and improve cognitive function, which is especially important for those who need to concentrate on work or study.

However, there are still some things to note when choosing to drink coffee after breakfast. The first is to control the intake. Excessive intake of caffeine may cause adverse reactions such as increased heart rate, insomnia and anxiety. The second is to avoid consuming a large amount of food containing irritating ingredients (such as spicy food) at the same time when fasting.

The truth about black coffee reducing swelling

Some people believe that drinking black coffee on an empty stomach in the morning can help reduce swelling. However, there is no scientific basis for this claim.

First, caffeine does not directly reduce the amount of water in the body. Although it may have a diuretic effect, its effect is very limited and not enough to significantly affect the body's water balance.

Secondly, if you drink coffee on an empty stomach, it may cause excessive gastric acid secretion and stomach discomfort, which in turn aggravates gastrointestinal problems and has a negative impact on the entire digestive system.

Finally, when choosing whether to drink coffee, you also need to consider your personal physical condition and habits. If you are prone to hyperacidity or other related problems, it is best to avoid consuming large amounts of stimulating food or drinks on an empty stomach.

in conclusion

In summary, drinking black coffee after breakfast may be more appropriate, because food can act as a buffer and provide a protective barrier. At the same time, consuming a moderate amount of caffeine can also refresh, increase alertness, and improve cognitive function.

However, it is important to note that excessive caffeine intake may lead to adverse reactions. In addition, consuming large amounts of stimulating food or drinks on an empty stomach may have a negative impact on the digestive system.

The most important thing is that everyone's physical conditions and habits are different. Therefore, when choosing whether to drink coffee after breakfast or on an empty stomach, please make a wise choice based on your own situation.
