The dazzling fruit stalls add a "dopamine color" to the sultry summer.
But for some people, it may be "dangerous goods"!
These 3 fruits,
Don’t be greedy if you like to eat again
Food allergies are not very rare.
The English Weekly of the China Centers for Disease Control and Prevention released a series of research papers on food allergies on Chinese people to analyze the food allergies of different people in my country.
The results showed that the prevalence of food allergies from 2009-2018 was 8%, an increase of 60%compared with the previous 10 years (5%), indicating that the prevalence of Chinese food allergies was on a rise.
So, in summer, which fruits do we have to be "wary"?
Mango is allergic, be careful if you touch it
When it comes to fruit allergies, the first thing many people think of is mango, and its "allergic person setting" is indeed more deeply rooted in people’s hearts.
Mango is rich in vitamin C, vitamin A, protein, dietary fiber and antioxidant, but mango also contains a variety of sensitized ingredients, such as aldehyde acid, allergenic protein, etc.
Generally, fruit allergies are superfluous reactions, and symptoms appear fast.Some people may be the starting rash, but for a small number of people with serious allergies, it can even cause throat edema!
In addition to mango allergies, except for a superfrigence reaction of symptoms within a few minutes to half an hour, there are late hairstyle allergic reactions that occur 48 or 72 hours, which are mainly manifested as skin symptoms.
As long as you touch the mango -contacting mango skin, mango meat, tree juice, damaged leaves, shells, and even trunks, there will be different degrees of allergic symptoms, mainly in contact with dermatitis and oral allergies.Skin inflammation, itching, rash, or blisters.There are also symptoms of respiratory tract and digestive tract.
Peach is allergic, and there are risks in absorbing
In fact, according to the European survey released by the EU Resources Health Commission in 2010, peaches are the most likely to induce allergies.
A retrospective study of the Beijing Union Hospital on the severe allergic response of the Chinese population also shows that among the 1501 severe allergic reactions induced by food, 20%are induced by fruits/vegetables, and the most common allergenic fruits are peaches.
As a member of the Rosaceae plant, peach allergies include two forms: one is truly allergic to peaches, and the other is allergic to birch pollen.
① Patients with allergies of birchus will have "peach allergies" because this protein in the peach is similar to the allergens of birch pollen. The patient’s body may recognize the peach as a birch pollen, which can cause allergic reactions.
Most peaches are induced by allergies, and some can also cause allergic reactions by inhalation or skin contact.
② If it is allergic to the peach itself, symptoms such as redness, peeling, itching and other symptoms of the corners of the mouth appear after eating, then consumption should be stopped immediately, and the symptoms should be visited in a timely manner.
Pineapple, is "tie mouth" a manifestation of allergies?
After eating pineapple, some people will have allergic symptoms such as itching and redness of the skin.
This is because pineapple contains a bioside and pineapple protease.
Biofoside stimulates the oral and esophagus mucosa and itching the oral cavity; and pineapple protease is a heterosexin.
After eating people with allergies to this protein, most of the symptoms such as abdominal pain, vomiting, diarrhea, dizziness, itching, especially children with poor immunity development and delicate skin, are more likely to cause allergies.
In severe cases, dyspnea, decreased blood pressure, and coma, etc., must be sent to the hospital for rescue.
When eating pineapple, it feels like "tie mouth". This is not allergic, nor is it that pineapple protease stimulates the oral mucosa, but the calcium oxalate needle crystal in pineapple is really tie your mouth.Soaked salt water and hot water.However, the calcium oxalate pinching can be dissolved in the water.
Do these 3 steps,
Copy fruit allergy
1 action reduces most of the risk
The allergens of many fruits are mainly gathered on the peel, and the flesh content is less.So if you have a slight allergies, you can cut the thickening point when peeling, so that you can eat less occasionally.
For example, a type of protein that causes peach allergies exists in large quantities of peach skin, so it may effectively reduce symptoms after peeling.Of course, it is best not to eat serious allergies.
Choose low allergens content
Sometimes I know that I will be allergic, but they are really greedy. You can choose a variety with low allergens.For those who are allergic to peaches, you can choose a peach variety with light aroma and less nutrition.
Because of the high level of allergens in high -quality peach varieties, the content of allergens will also increase as the storage time is prolonged, and there is a high content of allergens in oil peaches.
Principles of step -by -step progress
When allergens are not clear, you can first test whether you have been allergic to the food that have not been tried.
Take mango as an example. First, apply a little mango juice on the skin or lips to see if it will cause allergic reactions such as inflammation and itching; if there is no response, then the mouth contains a small amount, and then see if there is a allergic reaction characteristics.
Without allergic reactions, you can eat a small amount.After a period of time, you can eat with peace of mind.
Reminder: Triggering allergic proteins are high in immature mango, so before you are not sure if you are allergic to mango, you should try to avoid contact with raw mango when testing.
