Fish, shrimp, shellfish and other foods are rich in purine, and gout is caused by abnormal purine metabolism in human body. Therefore, gout patients should fast all meat and food with high purine content during acute attack. During the remission period, you should eat fish and meat quantitatively, and it is strictly forbidden to eat too much at one time.
At this time, fish with less purine can be selected appropriately, such as herring, salmon, tuna, white fish, lobster and so on. Use less fish with more purines, such as carp, cod, halibut, perch, eel and eel; Sardines, anchovies and fish eggs with high purine content are prohibited.
2. Patients with hemorrhagic diseases.
Fish fat contains eicosapentaenoic acid (EPA), which can prevent cholesterol from adhering to the blood vessel wall and is very beneficial to atherosclerosis. However, excessive intake of EPA will inhibit platelet aggregation, which will easily aggravate the bleeding symptoms of patients with hemorrhagic diseases and is not conducive to the recovery of the disease.
3, liver and kidney function is seriously damaged.
Fish food is rich in protein, too much intake will increase the burden of liver and kidney. People with severe liver and kidney function should eat fish quantitatively under the guidance of a doctor.
4. People who take certain drugs.
Chlorpheniramine and diphenhydramine are histamine receptor antagonists, while histidine-rich foods such as fish and shrimp can be converted into histamine in the body. If these antihistamines are taken together, it will inhibit the decomposition of histamine, cause histamine accumulation, and induce dizziness, headache, palpitation and other symptoms.

The efficacy and function of fish
1, eat fish for depression.
Scientists point out that 5% people in the United States suffer from severe mental depression, while only 0. 1% people in Japan suffer from severe mental depression, which is 1/50 in the United States. Studies show that the above differences are related to the amount of fish eaten in different eating habits of the two countries.
Studies have found that there is a special fatty acid in fish, which is related to the "happy hormone" in the human brain. It has the function of relieving mental tension and balancing emotions. People who don't eat fish or eat less fish often have lower levels of "happy hormones". Americans don't often eat fish, so there are more people suffering from depression.
2. Eat fish to prevent asthma.
As the saying goes, "Fish makes a fire, and meat produces phlegm." Therefore, for a long time, many people regard eating fish as an important cause of asthma, so they have always been taboo to eat fish. However, recent studies by experts have found that eating fresh fish regularly is not only harmless to asthma patients, but also beneficial to prevent asthma attacks.
Unsaturated fatty acids contained in fresh fish can prevent or reduce the production of inflammatory mediators in human body, and the onset of asthma is closely related to the release of inflammatory mediators.
In addition, unsaturated fatty acids can also reduce tracheal inflammation to a certain extent, thus helping to prevent the occurrence and recurrence of asthma or reduce the degree of asthma symptoms.
3, eat less fish dementia.
Canadian scientists have found that the DHA fatty acid content in the blood of healthy elderly people is much higher than that of Alzheimer's patients, and the DHA content in the blood of Alzheimer's patients is 30%~40% lower than that of healthy elderly people on average.
Scientists believe that DHA is an essential nutrient for the activity and vitality of brain cells, which helps to improve the transmission of nerve information and enhance the ability of thinking and memory. Therefore, eating more fish in the elderly can reduce the occurrence of dementia.
4. Eat fish to prevent stroke.
By comparison, scientists found that as an economically developed country, the number of people suffering from stroke in Japan is much lower than that in some European and American countries, because Japanese people eat more fish. Eating more fish has a protective effect on cardiovascular and cerebrovascular diseases.
Studies have shown that the higher the content of protein and sulfur-containing amino acids in the diet, the lower the incidence of hypertension. Fish protein is rich in egg amino acids and taurine, both of which are sulfur-containing amino acids, which can affect the regulation mechanism of blood pressure and increase urinary sodium excretion.
So as to inhibit the influence of sodium salt on blood pressure and reduce the incidence of hypertension. Experts suggest that one of the effective ways for middle-aged and elderly people to prevent cardiovascular and cerebrovascular diseases is to take three or four grams of fish oil every day.
5, eat fish to prevent aging.
In German history, there was a famous prime minister named Bismarck. For years, he ate too much and smoked too much. At the age of 68, he was weak, wrinkled and glassy-eyed, as if death were waving to him.
But then he listened to the doctor and ate herring every day. Soon, a miracle appeared: his skin was rosy, his eyes were bright and he was full of energy, and he lived until he was 83 years old.
