Contains large amounts of pectin, persimmon tannin, soluble astringents, and other ingredients that can easily undergo chemical reactions with gastric acid, coagulating into indissolvable lumps. These hard masses can block the pylorus, the exit of the stomach, causing pressure to rise, leading to gastric distension and a feeling of abdominal bloating and pain. Persimmons:
Contains substances such as persimmon tannin, pectin, tannic acid, and phlobaphene, which have a strong astringent effect. When consumed on an empty stomach and encountering strong gastric acid, they can easily combine with it to form hard, indissolvable masses. Small masses may be excreted with feces, but if they form large masses, they can easily cause "gastric persimmon stone disease," known in Traditional Chinese Medicine as "persimmon stone disease." Bananas:
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 magnesium levels in the blood, disrupting the magnesium-to-calcium ratio in the body, which can inhibit the cardiovascular system and is detrimental to health. Oranges:
Oranges contain a large amount of sugar and organic acids. Eating them on an empty stomach can irritate the gastric mucosa. Hawthorn:
The sour taste of hawthorn has the effect of promoting qi and aiding digestion, but if consumed on an empty stomach, it not only depletes qi but also increases hunger and aggravates stomach ailments. Sugarcane and Fresh Lychees:
Do not consume excessive amounts of sugarcane or fresh lychees on an empty stomach, as doing so can cause a sudden influx of excessive high sugar levels into the body, leading to "hypertonic coma."
