Ms. Wei, who has always loved sweets, bought 5 Jin of litchi. When she got home, she ate all the lychees while watching TV. "I want to eat litchi as a meal and lose weight by the way." Ms. Wei said that she didn't expect to clean the "battlefield" after dinner, and suddenly felt sick, followed by dizziness, palpitation and cold sweat. Just when she wanted to call her family, she fainted in front of her eyes and woke up in a hospital bed.

The deputy chief physician of the Department of Gastroenterology of Zhengzhou People's Hospital said that Ms. Wei is a typical "litchi disease". This kind of patients mostly occur in June and July when litchi is on the market. The main reason is that eating too much litchi leads to hypoglycemia. Litchi tastes sweet, which means there is a lot of sugar. How can eating too much cause hypoglycemia?

In this regard, Wang Yujie introduced that litchi contains a lot of sugar, of which fructose content exceeds 80%. Such a high concentration of fructose will stimulate the pancreas to secrete a lot of insulin and decompose and transform the original glucose in the body; At the same time, fructose, which needs to be converted into glucose by the liver to be utilized by the body, accumulates in the body due to excessive intake, so that glucose is consumed too much and cannot be supplemented, resulting in hypoglycemia symptoms such as dizziness, palpitation, pallor, dizziness and fainting.

"Eating a lot of litchi on an empty stomach is more likely to cause hypoglycemia." Wang Yujie said that eating a lot of litchi will affect normal eating, and the glucose content in the body will not be supplemented, which will aggravate the reaction of "litchi disease". "If the rescue is not timely, you may even die."

"In the spring of the four seasons under the Luofu Mountain, Lu Orange and Yangmei are new. 300 lychees a day, I don't want to grow up to be a Lingnan person. " Su Shi, a literary master, undoubtedly advertised the sweetness and delicacy of litchi, making litchi a must-have fruit in summer.

However, litchi is delicious and delicate. If you eat too much at a time, especially on an empty stomach, people can easily fall into danger unconsciously while enjoying delicious food. Experts remind that half an hour after a meal is a good time to eat litchi, so we must control the amount.

Eat litchi no more than 1 kg a day.

Wang Yujie suggested that litchi is delicious, but don't be greedy. Adults should not eat more than a catty of litchi a day, and children should not eat more than five lychees at a time. "Especially don't eat more on an empty stomach. Half an hour after a meal is a good time to eat lychee. " Wang Yujie said.

When it comes to eating litchi, many people still feel depressed, because eating litchi is easy to get angry. In this regard, Wang Yujie said that the way to eliminate the anger of litchi has actually existed among the people. Litchi Festival in the south is usually about picking and tasting litchi in the morning. There must be salted fish in the dishes you eat at noon, because salt can relieve the anger of litchi.

Therefore, he suggested peeling litchi and soaking it in light salt water for a while before eating, or drinking a little light salt water and mung bean water after eating litchi. Moreover, studies have shown that litchi peel has the effect of removing fire. After the litchi peel is fried, soak it in water or remove the fire.

"Especially try not to eat lychee on an empty stomach. If there is, it is best to drink some sugar water to supplement sugar, so as not to cause hypoglycemia. " Wang Yujie warned.

Sweet potatoes, persimmons and milk should not be eaten on an empty stomach.

Eating litchi on an empty stomach has caused such a big trouble. So what other foods are not suitable for eating on an empty stomach? According to clinical experience, Wang Yujie listed as follows:

Sweet potato. Because sweet potato contains tannin and gum, eating on an empty stomach will stimulate the stomach wall to secrete more gastric acid, causing "heartburn".

Persimmon, hawthorn. Persimmon is rich in tannic acid, which will produce water-insoluble precipitate under the action of gastric acid, and combine with pectin, food residue and so on to form agglomeration; Hawthorn is rich in pectin, which will gel when it meets gastric acid and condense into blocks in the stomach, resulting in stones. "In our gastroscope room, stones such as this kind of stomach persimmon stone are often taken, and the largest one is the size of an apple." Wang Yujie said.

Garlic, cold drinks. Garlic is rich in spicy allicin, which will strongly stimulate the gastrointestinal wall and cause gastrointestinal spasm and abdominal pain. At this time, you can eat pasta to neutralize it; Cold drinks, due to the low temperature, will also stimulate the gastrointestinal wall and cause acute abdominal pain, and will also affect the heart function.

Yogurt, milk. Yogurt is rich in lactic acid bacteria beneficial to human body. When the Ph value of gastrointestinal tract is above 5.4, lactic acid bacteria can reproduce well. On an empty stomach, the Ph value of gastrointestinal tract dropped to about 2, and the activity of lactobacillus decreased seriously. So yogurt should be drunk within two hours after meals. At this time, the stomach environment is suitable for the survival of lactic acid bacteria and beneficial to the unique health care function of yogurt. Milk is rich in protein, which can be fully hydrolyzed and absorbed with gastric juice only under the action of starch. If you drink milk on an empty stomach, protein will be consumed as calories and nutrients will be "wasted". Therefore, Wang Yujie suggested that it is best to eat some starchy foods such as biscuits and cakes when drinking milk.

Bananas. Bananas contain more magnesium. Eating too many bananas on an empty stomach will lead to a sudden increase in magnesium content in human blood, which will lead to an imbalance in the proportion of calcium and magnesium in blood and inhibit cardiovascular physiological functions.
