It's time for litchi to go on the market again, think about whether the crystal clear flesh is salivating, four feet, five feet...? But the litchi "gets hot", are the friends who are prone to get hot hesitate?

Dip in soy sauce! Add salt! These are legendary recipes that can be used to remove fire for lychees, but is it really effective?

　　 The truth about "Soaking in salt water does not get hot"

　　 Some fruits are warmer and dry. As the saying goes, one litchi has three fires.

　　 People often think that eating too much lychee will lead to dry mouth and tongue, even sweating, dizziness, coma and other "lychee disease" manifestations. In fact, this is all related to the sugar in lychee.

　　Litchi has a high sugar content, accounting for about 16%, and the sugar in lychee is more easily absorbed by the human body than the sugar of other fruits, causing blood sugar to rise, causing dry mouth and other "getting up" signs.

　　Eating too much, when the blood sugar rises significantly, it will also stimulate the reflex secretion of insulin in the human body, rapidly reduce blood sugar, and appear "Litchi disease" (essentially a hypoglycemic reaction).

　　Drink some salt water after eating lychee, which can alleviate the human body reaction caused by the sugar of lychee, play the role of slowly raising blood sugar, and achieve the so-called effect of reducing fire.

　　 These fruits are sweeter with a little salt

　　 represents cantaloupe, peach, pear, plum

　　 These fruits are soaked in salt water, and they taste sweeter and taste better.

Why salt can increase the sweetness of fruits? It can be simply understood as follows: because there is a clear difference in taste between salty and sweet, when food is mainly sweet, adding a small amount of salty taste can increase the gap between the two tastes. So it feels "sweeter".

　　 From a professional perspective, the mechanism is:

　　 Soaking fruits with low-concentration salt water will cause dehydration of the fruit cells, reducing water content, and naturally higher sweetness; dehydration also increases the brittleness of the fruit and makes it more refreshing to eat. Salt water can also dissolve a small amount of organic acids in the fruit, which will also increase the sweetness of the fruit.

　　 Generally speaking, fruits with slightly hard texture can be eaten in this way; fruits with soft texture, such as bananas, grapes, etc., may taste worse if they are immersed in salt water.

　　 stands for pineapple

　　Some fruits must be treated with salt water before they can be eaten, such as pineapple.

Commonly known as "pineapple disease" is caused by the improper way of eating pineapple. It manifests as headache, vomiting, abdominal pain, diarrhea, flushing of the skin, itching of the whole body, numbness of the limbs and tongue within 15 minutes to 1 hour after eating pineapple. In severe cases, breathing difficulties and shock may even occur. This is because the pineapple enzyme contained in pineapple causes allergic reactions in the body.

Therefore, before eating pineapple, you must slice the pineapple that has been peeled off and picked out the thorns, and soaked in salt water for 30 minutes. This can destroy the protein of the pineapple and make the enzyme decomposition of the pineapple ineffective, thereby avoiding direct consumption and causing pineapple disease .

　　 Although pineapple enzymes are destroyed after salt water soaking, it helps to avoid the disease, but if you have had an allergic reaction to pineapple in the past, it is recommended not to eat it.

　　 Of course, there are also fruit allergies, even if it is soaked in salt water, the problem cannot be solved, such as mango allergies. However, most people are allergic to mango skin instead of mango flesh, so just be careful not to eat the flesh close to the skin.

　　 In particular, not all fruits containing enzymes need to be treated with salt water to eat. For example, papaya containing papaya enzyme can be eaten directly.

  Precautions

　　 Although the concentration of salt water used to soak fruits is very low, it is always not safe for people suffering from obesity, high blood pressure, and diabetes. It is even more inappropriate to eat directly with fruit dipped in salt.
