1. It is not advisable to chew on it.

When eating crabs, you should pay attention to four clearances. First, the crab stomach should be cleared. The crab stomach is commonly known as the crab urine bag, which resembles a triangular bony bag at the front edge of the back shell, with dirty sand inside; Second, it is necessary to eliminate the crab intestine, that is, a black line from the crab stomach to the crab navel; Third, we must remove the crab heart, which is commonly known as the hexagonal plate; Fourth, it is necessary to remove the crab gills, that is, the two rows of soft things that grow on the crab's abdomen like eyebrows, commonly known as crab eyebrows.

These parts are dirty and inedible, so don't chew them on them to avoid food poisoning.

2. Do not eat long-term cooked crabs.

Cooked crabs stored are very susceptible to bacterial invasion and contamination, so crabs should be eaten freshly and not stored. In case you can't finish eating, the rest must be kept in a clean, cool and ventilated place (preferably in the refrigerator), and must be returned to the pot and steamed thoroughly when eating.

3. Do not eat with tea.

Do not drink tea when eating crabs and within 1 hour after eating crabs. Because boiling water will dilute stomach acid, tea will make some components of crab coagulate, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.

4. Don't eat too much.

Even if you are greedy, you have to endure it: because crab meat is cold, it is not advisable to eat more. People with spleen and stomach deficiency should pay special attention to avoid abdominal pain and diarrhea. For abdominal pain and diarrhea caused by eating crabs, you can use 15 grams of warm Chinese medicine perilla, with 5 6 slices of ginger, and decoction with water.

5. Patients should not eat.

Because crabs are cold and contain a lot of protein and high cholesterol, people with certain diseases should fast or eat less. For example:

Patients with colds, fevers, stomach aches, and diarrhea can be exacerbated by eating crabs.

Patients with chronic gastritis, duodenal ulcer, cholecystitis, gallstones, and hepatitis are active in the active stage, and it is best not to eat crabs to avoid aggravating the condition.

Crab roe is high in cholesterol, and people with coronary heart disease, high blood pressure, arteriosclerosis, and hyperlipidemia should eat less or no crab roe, otherwise it will aggravate the condition.

People with allergies, if they eat crabs, they are prone to nausea, vomiting, and hives.

People with a weak spleen and stomach should eat less or no crabs, because it is easy to cause abdominal pain and diarrhea after eating.

6. It is not suitable to eat raw crabs.

Crabs generally feed on dead animals or humus, so the body surface, gills and gastrointestinal tract of crabs are covered with various bacteria and sludge. The crab should be steamed and boiled thoroughly, and it is generally heated for more than 30 minutes after boiling to have a disinfection effect.

Crabs are eaten in the autumn months of bai. Eating crabs should be paid attention to the next seven points:

1. (Lake) crabs should be steamed and cooked thoroughly, and raw crabs should not be eaten.

River (lake) crabs feed on animal carcasses or humus, so the body surface, gills and gastrointestinal tract of crabs are covered with all kinds of bacteria and sludge. Therefore, it must be steamed and eaten, otherwise it will eat the germs or parasites in the crab's body.

2. (Lake) crabs should be eaten alive, and dead crabs should not be eaten.

The stiffness period and autolysis period of river crabs after death are greatly shortened, and the bacteria in the crab will multiply rapidly and spread to the crab meat, causing vomiting, abdominal pain and diarrhea to eaters.

The shell of the fresh live crab is blue-black, shiny, the umbilicus is full, and the belly is white. The shell of the dying crab is yellow, and the crab legs are soft, making it difficult to straighten out.

3. Eat it freshly steamed, not stored.

If you can't finish eating, the rest must be kept in a clean, cool and ventilated place, and you must return to the pot and cook and steam thoroughly when eating.

Fourth, don't chew the crab in a hurry.

When eating crabs, pay attention to four clearances after opening the lid: remove the crab stomach, which is the triangular bone bag in the crab lid, eat the crab lid first, scoop out the middle crab stomach part with a small spoon, and gently suck the crab roe wrapped outside.

Be careful not to suck the triangular pyramid-shaped crab stomach in the middle, and discard it if there is dirty sand inside; After eating the crab cover, it is the turn of the crab body, first use scissors to cut off the excess crab legs and crab mouth; Use the handle of a spoon to pick out a hexagonal sheet in the middle of the crab body, which is the crab heart part and should be discarded.

There is also crab intestines, that is, a black line from the crab stomach to the crab navel; The gills, i.e., the two rows of soft eyebrow-like stuff that grow on the crab's belly, should be removed.

1. Don't eat dead crabs.

Crabs contain a lot of histidine, and after death, bacteria multiply in the crab's body, which will allow histidine to form histamine, a substance harmful to the human body, and the longer the crab dies, the more histamine content in the body, if people eat dead crabs, they will have allergies or poisoning, so dead crabs must not be eaten.

2. Don't eat cooked crabs that have been left for a long time.

Crabs should not be eaten if they have been dead for a long time, but they should not be eaten if they have been cooked for a long time. Because the protein content in crabs is very high, it is easy to spoil and deteriorate, and it is easy to be contaminated by bacteria at room temperature, so crabs must be steamed and eaten, and it is best not to eat crabs that have been stored for too long.

3. Don't eat raw crabs.

Some people salt, soak the crab in vinegar and wine and eat it, and it is easy to inhale the lung flukes in the raw crab into the body.

When eating crabs, be sure to remove their stomachs, intestines, hearts, gills, etc.: crab stomachs are triangular bony packets, and there will be a lot of dirty sand in them; Crab intestines are not clean and should be removed; The crab heart is also called a hexagonal board, which must be removed; If you can't eat the gills, you have to remove them.

6. Don't eat too much at once.

The protein content of crabs is high, and the cholesterol content of crab roe is high, once used too much is not conducive to human digestion and absorption, and crabs are cold foods, eating too much will cause abdominal pain and diarrhea. When steaming crabs, you can put some perilla leaves, which can play a role in sweating and relieving the surface, and spreading qi. In addition, you can also eat crab with ginger and vinegar to help digestion and relieve fishy greasy.

Crabs should be eaten less and not too much. Those with cold crab meat and spleen and stomach deficiency should pay attention to avoid causing abdominal pain and diarrhea. Do not drink tea during or within 1 hour after eating crabs.

02 Don't eat crab intestines, all that exists here are crab excrement, when the crab body is broken, you can see the black crab intestines in the position of crab roe and crab meat, just remove it directly, this thing is equivalent to shrimp line.

03 The crab heart is also not edible, the crab heart is also called the crab hexagonal plate, the appearance is hexagonal, it is the thickest position of the crab paste in the middle of the abdomen, the crab heart is an extremely cold substance, and the body will have various chills after use.

Histamine is a toxic substance, if the crab body is contaminated by bacteria with strong decarboxylase action, the histidine in the crab meat will be removed by decarboxylase to remove the carboxyl group will produce histamine substance, with the passage of time of death, the accumulation of histamine in the crab body will be more and more, and it is easy to be poisoned after eating;

2. Avoid eating half-cooked or raw crabs: crabs with paralytic paralytic solitary bacteria of paragonim paragonim are parasitic in the human lungs after being inhaled into the human body without high temperature disinfection, causing lung damage;

3. Avoid eating crabs' gastrointestinal ribs: Crabs like to eat corrosive food, which often contain pathogenic bacteria or toxic sundries. Remove these parts before eating crabs;
