In fact, this kind of people feel wronged themselves, because everyone knows that seafood is actually a delicious food, but they can't touch seafood for physical reasons, and even a little more serious may lead to death or other serious consequences. It's a bit like some children are naturally allergic to candy and can't eat candy since childhood. It can be said that it is very distressing for a child not to eat sugar.
In fact, one of the reasons of seafood allergy is that seafood contains a large number of heterogeneous proteins, which can directly or indirectly activate immune cells to some extent, thus causing the release of chemical media, and a series of complex reactions will occur due to this chemical media. In this way, there will be a joint action of antibodies and antigens, and then the human body will have allergic symptoms.
Seafood is delicious, but allergies are hard to prevent. This is because seafood contains a certain amount of histamine, which is actually an active amine compound. Histamine, as a chemical conductor in the body, can actually affect many cellular reactions, including allergies, inflammation, gastric acid secretion and so on.
At the same time, these reactions will also affect brain nerve conduction. If so, it will cause people to want to sleep and other effects, so some people may be sleepy. However, histamine mainly exists in mast cells, that is to say, histamine exists in the mucosa of lung, liver and stomach, which is a very important part of the body.
So some people are allergic to seafood for no reason. Some studies have also said that there is still an unknown substance in seafood, and it is temporarily impossible to determine what causes seafood allergies. However, no matter what the substance is, everyone should remember that it is too late to eat too much seafood, otherwise there will be real problems.
In addition to seafood, these foods are also prone to allergic reactions:
1, Nuts: Some foreign researchers say that nuts are the chief culprit of food allergy deaths, among which peanuts are the most fatal cases, and nearly half of nut allergies are related to peanuts.
2. Milk: The incidence of milk allergy is three times that of peanut allergy, and peanut allergy is the most common in infants, which is related to the imperfect digestive system of infants.
3, soybeans: people who are allergic to soybeans will have symptoms such as tingling in the mouth and abdominal pain after eating. Many foods in China contain soybean ingredients, which need to be carefully selected.
