Summer is the season for crayfish to go on the market in large quantities, and it's also the favorite of many people. Many people like to eat crayfish, which is not only rich in protein, but also very delicious, so it's very popular. But if you haven't eaten the day before, can you put it on the next day? Can you eat crayfish every other night? What are the consequences of eating crayfish every other night?
1. Crayfish can't be eaten overnight
Crayfish belongs to seafood. Seafood is a kind of fresh food. If there is no so-called fresh food overnight, it will lose the purpose of eating seafood. Moreover, all seafood are not recommended to stay overnight, because many seafood overnight will produce harmful substances to the body.
2. Bad taste
Crayfish is widely accepted and popular because of its delicious taste. However, once it is stored at room temperature for a long time after being cooked, the protein in the crayfish will degrade. The taste of the crayfish will not be as delicious as when it is fresh, nor so nutritious and healthy. The degraded protein will cause certain harm to the kidney.
3. Heavy metal poisoning
The head of crayfish contains a lot of calcified substances and heavy metals. After the crayfish is cooked for a long time, the heavy metals and other harmful substances in the head are easy to spread to the edible part of crayfish, and eating too much will lead to heavy metal poisoning.
4. Carcinogenicity
All foods will produce nitric acid and nitrite after long-term storage. After use, they will be converted into nitrates and nitrites in the body. These substances are carcinogens of workers and are easy to cause cancer.
5. Hypoxia
Eating crayfish overnight is easy to lead to the existence of high-level nitrite concentration in the body, causing poisoning. The mechanism of nitrous acid poisoning is to oxidize the iron element in the blood, change the hemoglobin into methemoglobin, lose the oxygen carrying capacity, make the body appear anoxia, cyanosis, and death.
6. Not suitable for pregnant women
After a long period of room temperature, crayfish will produce nitrite, which can pass through the placental barrier. Fetuses under 6 months old are particularly sensitive to nitrite and have teratogenic effects on fetuses.
7. Attention is also needed
Eat crayfish to avoid with persimmon, tea, beer. Crayfish is a high protein food, such as persimmon, strong tea, pomegranate, grape, etc. the tannic acid in these foods will combine with the protein to form an insoluble combination, which is not easy to be digested and absorbed in the gastrointestinal tract, forming stones. Because shrimp is warm, eating shrimp at the same time, don't drink ice beer, especially for people who are sensitive to gastrointestinal tract, may cause diarrhea.
