When it comes to what not to eat on an empty stomach, it is best to be highly vigilant to avoid unknowingly harming your body.
Fruits not to eat on an empty stomach:
Fruits not to eat on an empty stomach: Pineapple
It contains a very strong proteolytic enzyme. If eaten before a meal, it can easily damage the stomach wall.
Fruits not to eat on an empty stomach: Sugarcane
It has a high sugar content and is not suitable for consumption on an empty stomach, as it can irritate the gastric mucosa, leading to stomach pain and a bloated feeling.
Fruits not to eat on an empty stomach: Hawthorn
It contains a large amount of organic acids such as citric acid, hawthorn acid, and citric acid. Eating it on an empty stomach can sharply increase the acidity in the stomach, causing adverse stimulation to the gastric membrane, which can lead to bloating, belching, acid reflux, and can even aggravate gastritis and gastric ulcers.
Fruits not to eat on an empty stomach: Fresh Lychee
It has a high sugar content. Eating too many fresh lychees on an empty stomach can cause a sudden influx of excessive high sugar into the body, leading to "hypertonic coma".
Fruits not to eat on an empty stomach: Tomatoes
They contain a large amount of pectin, persimmon tannin, soluble astringents, and other components, which can easily react with stomach acid to form insoluble lumps. These hard lumps can block the pylorus (the exit of the stomach), increasing pressure inside the stomach and causing acute gastric dilation, which makes people feel bloated and painful.
Fruits not to eat on an empty stomach: Persimmons
When the stomach is empty, it contains a large amount of gastric acid, which can easily react with persimmon tannin, gum, pectin, and soluble astringents in persimmons to form "bezoars" (stomach stones). This can cause epigastric pain, nausea, vomiting, gastric dilation, gastric ulcers, and even gastric perforation and bleeding.
Fruits not to eat on an empty stomach: Bananas
They contain a large amount of magnesium. If a large number of bananas are eaten on an empty stomach, it will cause a sharp increase in the magnesium content in the blood, disrupting the balance of magnesium and calcium in the human body. This has an inhibitory effect on the cardiovascular system, which is not good for health or weight loss.
Fruits not to eat on an empty stomach: Oranges
They contain a large amount of sugar and organic acids. Eating oranges on an empty stomach can irritate the gastric mucosa, increase stomach acid, and lead to a feeling of fullness, bloating, and acid reflux.
Other foods not to eat on an empty stomach:
Strong tea, coffee, alcohol
Take green tea as an example. Although green tea is unfermented, it retains a large number of natural substances, such as tea polyphenols and caffeine. It is these components that give green tea its effects of anti-aging, cancer prevention, antibacterial, and anti-inflammatory properties. However, if consumed on an empty stomach, the harm to the human body is also very significant.
When consumed on an empty stomach, some substances in tea are easily absorbed in excess, such as caffeine and fluorine, which can cause some people to experience symptoms like palpitations, dizziness, weakness, and mental confusion. Once these symptoms appear, you should immediately eat a piece of candy or drink a glass of sugar water, and the symptoms will gradually disappear. However, if too much fluoride accumulates in the body, it may cause intestinal diseases and affect kidney function.
The principle of drinking coffee on an empty stomach is the same as that of tea. Caffeine stimulates and excites the sympathetic nervous system but has a negative effect on appetite, reducing it. Moreover, the stomach is stimulated, and gastric juice secretion increases, which is extremely detrimental to the stomach, especially for patients with gastric ulcers, as it can worsen the condition.
Cold drinks and overly spicy food
Before and after exercise, many people like to drink various cold drinks and beverages. This can easily irritate the gastric mucosa, leading to gastritis. This is because our digestive tract needs to maintain a warm environment to ensure the normal transport of microcirculation, oxygen, nutrients, and waste. If you eat cold drinks on an empty stomach, the mucous membrane will cool down, causing blood vessels to constrict, which can ultimately lead to ischemia of the gastric mucosa and cause gastritis.
Furthermore, a sudden cold shock to the stomach can also stimulate the heart, causing these organs to have sudden spasms. Over the long term, this can lead to endocrine disorders, irregular menstruation in women, and other illnesses. Therefore, it is best to eat cold drinks between meals. It is not advisable to consume them immediately when the stomach is empty, after a heavy meal, or when sweating profusely.
