Fruits are healthy, but it's important to be mindful when eating them, as some can be harmful to your body when consumed on an empty stomach.
Tomatoes
They contain large amounts of pectin, tannic acid, soluble tannins, and other components that can easily react with stomach acid to form indissoluble clumps. These hard masses can block the pylorus of the stomach, increase pressure within the stomach, causing acute gastric dilation and a feeling of bloating and stomach pain.
Persimmons
When the stomach is empty, it contains a large amount of gastric acid, which can easily react with the tannic acid, gums, pectin, and soluble tannins found in persimmons, leading to persimmon phytobezoars. This can cause epigastric pain, nausea, vomiting, gastric dilation, gastric ulcers, and even gastric perforation or bleeding.
Bananas
They contain a large amount of magnesium. Eating a large number of bananas on an empty stomach can cause a sharp increase in the magnesium level in the blood, disrupting the balance of magnesium and calcium in the body. This can have an inhibitory effect on the cardiovascular system and is not good for your health.
Candied Kumquats
Oranges
Oranges contain a high amount of sugar and organic acids. Eating them on an empty stomach can irritate the gastric mucosa, leading to increased stomach acid, a feeling of fullness and bloating in the stomach, and acid reflux.
Black Jujubes
They contain large amounts of pectin and tannic acid, which can easily combine with stomach acid in the body to form hard masses in the stomach. It is especially inadvisable to eat too many before bedtime, and people with chronic gastrointestinal diseases should avoid them.
Fresh Lychees
Eating lychees on an empty stomach can irritate the gastric mucosa, leading to stomach pain and bloating. Lychees have a very high sugar content. Eating too many fresh lychees on an empty stomach can cause a sudden influx of excessive high-sugar substances into the body, leading to "hypertonic coma".
Hawthorn
It has the effect of promoting qi and aiding digestion, but if consumed on an empty stomach, it not only depletes qi but also increases the feeling of hunger and worsens stomach ailments.
Pineapple
It contains proteolytic enzymes. If eaten before a meal, it can easily cause damage to the stomach wall.
