contain a large amount of pectin, persimmon tannin, and soluble astringents, which can easily react with stomach acid to form indissoluble lumps. These hard lumps can block the pylorus of the stomach, increase intragastric pressure, cause acute gastric dilation, and lead to a feeling of stomach bloating and pain. Oranges
contain a lot of sugar and organic acids. Eating oranges on an empty stomach can irritate the gastric mucosa, increase stomach acid, and cause a feeling of fullness, bloating, and acid reflux in the stomach and spleen. Pineapple
contains very strong proteolytic enzymes. Eating it before a meal can easily cause damage to the stomach wall. Hawthorn
has a sour taste and is known for promoting qi and aiding digestion. However, if consumed on an empty stomach, it not only depletes qi but also increases hunger and worsens stomach ailments. Black Dates
contain a large amount of pectin and tannic acid, which can easily combine with stomach acid in the human body to form hard lumps in the stomach. It is especially not advisable to eat too many before bedtime, and people with chronic gastrointestinal diseases should avoid them. Fresh Lychees
have a very high sugar content and should not be eaten on an empty stomach, as they can irritate the gastric mucosa, leading to stomach pain and a bloated feeling. Moreover, eating an excessive amount of fresh lychees on an empty stomach can cause a sudden influx of excessive high-sugar levels in the body, leading to "hypertonic coma." Persimmons
When the stomach is empty, it contains a large amount of stomach acid, which can easily react with persimmon tannin, gum, pectin, and soluble astringents in persimmons to form bezoars. This can cause epigastric pain, nausea, vomiting, gastric dilation, gastric ulcers, and even gastric perforation and bleeding. Bananas
contain a large amount of magnesium. If a large number of bananas are eaten on an empty stomach, the magnesium content in the blood can suddenly rise, causing an imbalance in the ratio of magnesium to calcium in the human body, which has an inhibitory effect on the cardiovascular system and is detrimental to health.
