1. Tomatoes: Contain a large amount of pectin, persimmon phenol, soluble astringent and other ingredients, which are prone to chemical reactions with gastric acid, increasing the pressure in the stomach, causing gastric distension and stomach pain.

2. Persimmon: Contains persimmon phenol, pectin, tannic acid, tannin and other substances, which have a strong astringent effect. If you encounter strong acid on an empty stomach, it will easily combine with gastric acid to coagulate. It becomes a hard lump that is difficult to dissolve, causing "gastric persimmon stone syndrome".

3. Bananas; contain a large amount of magnesium. Eating them on an empty stomach will quickly increase blood magnesium, causing an imbalance in the ratio of magnesium and calcium in the blood, inhibiting the cardiovascular system, and being detrimental to physical and mental health. .

4. Oranges: Orange juice contains a lot of sugar and organic acids. Eating oranges on an empty stomach will irritate the gastric mucosa and cause gastric bloating and pantothenic acid.

5. Sugar cane: It is not advisable to eat too much sugar cane on an empty stomach, otherwise excessive sugar intake will cause "hyperosmotic coma".

6. Hawthorn: It tastes sour. Eating it on an empty stomach will increase hunger or cause stomach pain. In addition, hawthorn is rich in pectin, which will gel when exposed to gastric acid, and will condense into lumps in the stomach to cause stones. Lychee

7. Lychee contains a large amount of sugar, of which the fructose content exceeds 80%. Such a high concentration of fructose will stimulate the pancreas to secrete a large amount of insulin to break down and convert the original glucose in the body; at the same time, the fructose that needs to be converted into glucose by the liver before it can be used by the body, due to excessive intake, the liver has no time to convert. When accumulated in the body, glucose is consumed too much and cannot be replenished, causing symptoms of hypoglycemia such as dizziness, palpitation, paleness, dizziness, and fainting.

Eating a large amount of lychees on an empty stomach is more likely to cause hypoglycemia, because eating a large amount of lychees will affect normal eating, and the glucose content in the body will not be replenished, which will aggravate the reaction of "lychee disease" and "cannot rescue". If done in time, you may even die."

Suggestion: You can peel the lychees and soak them in light salt water for a while before eating them, or drink some light salt water or mung bean water after eating the lychees. And some studies have shown that lychee peel has the effect of removing internal heat. Frying the lychee peel and soaking it in water can also reduce internal heat.

What needs to be reminded in particular is: try not to eat lychees on an empty stomach. If you eat them, it is best to drink some sugar water to replenish sugar to avoid hypoglycemia.
