What are the dangers of eating too many crabs?

Every 100 grams of crab paste contains 466 mg of cholesterol, and every 100 grams of crab meat contains 65 mg of cholesterol. People with hyperlipidemia, hypertension, cardiovascular and cerebrovascular diseases, and obesity should eat crabs less frequently. It is best to selectively eat only crab meat and eat less or no crab roe and crab paste.

Do not eat dead crabs. After the crab dies, the glycogen in the body decomposes lactic acid, the rigor mortis and autolysis periods are shortened, and the parasitic bacteria in the crab body multiply rapidly and spread to the crab meat, causing the protein to decompose and produce histamine.

Persimmons are also very cold foods and should not be eaten at the same time as hairy crabs. Otherwise, they will combine with proteins and form "gastric persimmon stone disease", which will cause abdominal pain, vomiting and other symptoms. You should eat some warm foods, such as ginger. Now some citizens will eat some ginger when eating crabs, which is a good habit.

People with high blood sugar and blood lipids should not eat too much crab roe, especially crab roe, which contains a lot of cholesterol. Also, patients with cholecystitis can suffer from biliary colic.

Certain patients should not eat:

1. Eating crabs will aggravate the condition of patients suffering from cold, fever, stomachache and diarrhea.

2. People with chronic gastritis, duodenal ulcer, cholecystitis, cholelithiasis, and active hepatitis should not eat crabs to avoid aggravating their condition.

3. Crab roe is high in cholesterol. People with coronary heart disease, hypertension, arteriosclerosis, and hyperlipidemia should eat less or no crab roe, otherwise it will aggravate their condition.

4. People with allergic constitutions are prone to nausea, vomiting, and urticaria after eating crabs.

5. People with weak spleen and stomach should eat less or no crabs, because eating crabs can easily cause abdominal pain and diarrhea. If this happens, you can boil 15 grams of perilla and 5 slices of ginger to relieve pain and diarrhea.

Is it harmful to eat too many crabs?

Crab is a delicious food rich in vitamins and is very popular among people.

International unit. Crab also has certain medicinal value. It has the effects of promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, strengthening tendons and bones. It is often used by the people to treat bruises, promoting blood circulation and removing blood stasis, broken tendons and bones, etc.

However, some people experience abdominal pain, diarrhea, nausea and vomiting after eating crabs. The main reason is that they do not pay attention to hygiene and cause food poisoning. Therefore, you should pay attention to the following eight things when eating crabs.

1. Dead crabs should not be eaten. After being caught, river crabs often struggle and consume glycogen in their bodies, which increases lactic acid in their bodies. The rigor mortis and autolysis periods after death are greatly shortened, and the bacteria in the crabs will multiply rapidly and spread into the crab meat. Under weak acid conditions, bacteria will decompose the amino acids in the crabs, producing a large amount of histamine and histamine-like substances. Histamine is a harmful substance that can cause allergic food poisoning; histamine-like substances can cause vomiting, abdominal pain, and diarrhea in eaters. Therefore, dead crabs cannot be eaten, and should not be discarded. When buying crabs, you should pay attention to identifying the quality. The back shell of fresh live crabs is dark blue and shiny, the navel is full, the abdomen is white, and the crab legs are hard and strong. When the crab is placed on its back with its abdomen facing the sky, the crab can quickly turn over and crawl. The back shell of a dying crab is yellow, the crab legs are soft, and it is difficult to turn over.

2. Do not eat raw crabs: River crabs grow in the mud of rivers, lakes and marshes. They feed on animal carcasses or humus, so the crab's body surface, gills and gastrointestinal tract are covered with various bacteria and sludge. Before eating, the crab's body surface, gills and navel should be brushed clean, and then steamed and boiled thoroughly before eating. Some people get sick because they do not wash the crabs clean, do not steam or boil them thoroughly, or eat raw drunken or pickled crabs, which causes the bacteria or parasite larvae in the crabs to enter the body. Crabs often carry lung flukes and Vibrio parahaemolyticus. If they are not sterilized at high temperature, lung flukes can cause lung damage after entering the human body. If Vibrio parahaemolyticus invades the human body in large quantities, infectious poisoning will occur, showing symptoms such as intestinal inflammation, edema and congestion. Therefore, crabs should be steamed and boiled thoroughly, and generally heated for more than 30 minutes after boiling to achieve a disinfection effect.

3. Do not eat cooked crabs that have been stored for too long: stored cooked crabs are easily contaminated by bacteria, so crabs should be cooked and eaten immediately, not stored. If you cannot finish eating, the remaining crabs must be stored in a clean, cool and ventilated place, and must be re-cooked and steamed before eating.

4. Do not chew without care: When eating crabs, you should pay attention to the following four things. First, you should clean the crab stomach. The crab stomach is commonly known as the crab urine bag. It is a triangular bone bag in the center of the front edge of the back shell, which contains dirty sand. Second, you should remove the crab intestine, which is a black line from the crab stomach to the crab navel. Third, you should remove the crab heart, which is commonly known as the hexagonal plate. Fourth, you should remove the crab gills, which are two rows of soft things like eyebrows growing on the crab abdomen, commonly known as crab eyebrows. These parts are dirty and have no edible value. Do not chew without care to avoid food poisoning.

5. Don’t eat too much: Crab meat is cold in nature, so don’t eat too much. People with weak spleen and stomach should be especially careful to avoid abdominal pain and diarrhea. For abdominal pain and diarrhea caused by eating crab, you can use 15 grams of warm Chinese medicine Perilla, 5-6 slices of ginger, and boil them in water.

6. Do not drink tea while eating crabs or within 1 hour after eating crabs. This is because boiled water will dilute stomach acid, and tea will solidify some components of crabs, which are not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea.

7. Do not eat crabs with persimmons: Crabs are fat and persimmons are ripe, so you should be careful not to eat crabs and persimmons together. This is because the tannic acid and other ingredients in persimmons will coagulate the crab protein, and the coagulated substances will ferment and rot in the intestines for a long time, causing vomiting, abdominal pain, diarrhea and other reactions.

8. Some patients should not eat:

1. Eating crabs will aggravate the condition of patients suffering from cold, fever, stomachache and diarrhea.

2. People with chronic gastritis, duodenal ulcer, cholecystitis, cholelithiasis, and active hepatitis should not eat crabs to avoid aggravating their condition.

3. Crab roe is high in cholesterol. People with coronary heart disease, hypertension, arteriosclerosis, and hyperlipidemia should eat less or no crab roe, otherwise it will aggravate their condition.

4. People with allergic constitutions are prone to nausea, vomiting, and urticaria after eating crabs.

5. People with weak spleen and stomach should eat less or no crabs, because eating crabs can easily cause abdominal pain and diarrhea. If this happens, you can boil 15 grams of perilla and 5 slices of ginger to relieve pain and diarrhea.
