Fish is delicious and has high nutritional value. Everyone likes it, but not everyone can eat fish. Let me introduce the precautions for eating fish!

Who is not suitable for eating fish 1 and gout patients, because fish contains purine substances, and gout is caused by the disorder of purine metabolism in human body;

2. Patients with hemorrhagic diseases, such as thrombocytopenia, hemophilia and vitamin K deficiency, should eat less or not eat fish, because the eicosapentaenoic acid contained in fish can inhibit platelet aggregation, thus aggravating the bleeding symptoms of patients with hemorrhagic diseases;

3. In patients with liver cirrhosis, it is difficult for the body to produce coagulation factors during liver cirrhosis, and the platelets are low, which is easy to cause bleeding. If you eat sardines, herring, tuna, etc. rich in 20 C 5 enoic acid, your condition will deteriorate sharply, just like adding insult to injury;

4, tuberculosis patients, taking isoniazid, if eating some fish is prone to allergic reactions, ranging from nausea, headache, skin flushing, conjunctival congestion, etc., to severe palpitations, mouth and face swelling, rash, diarrhea, abdominal pain, dyspnea, elevated blood pressure, and even hypertensive crisis and cerebral hemorrhage.

Dietary precautions for eating fish Do not eat fish that is too red or white. Because of different species of fish, there are red-fleshed fish such as tuna and white-fleshed fish such as hairtail, but if the fish is too bright red or bright white, it is likely to be dyed? Credit? .

Take the lead? Eight points big? Yes. The size of a fish determines its taste and safety. Too small, the fish has not yet grown up and matured, the meat is not tender enough, and the fishbones will appear extra. Too big means that the fish is old, the meat is rough, and many harmful substances may be accumulated in the body. Therefore, buy fish and choose a head? Eight points big? The left and right ones are more suitable. For example, 1 kg and a half for carp and Wuchang fish, 0.5 kg ~ 1 kg for crucian carp and 4~5 kg for grass carp are suitable.

Don't buy those who block this promotion and whose eyes are turbid and sunken and whose gills are gray. Shopping? Iced fish? The eyes and gills should be observed first. Fresh fish have full eyeballs, clear corneas and bright gills. Secondly, the eyeball of fresh fish is not full, the cornea is wrinkled and slightly turbid, and sometimes the bleeding in the eye is red, and the gills are dark and grayish red or grayish purple. The eyeball of rotten fish collapses or shrivels, the cornea shrinks or breaks, and the gills are brown or grayish white.

Kill the live fish now and put it before eating. The quality of fish just slaughtered is not the best, because fish will have one? Acid discharge? The process needs to be placed for a while to be more delicious. Small fish such as grass carp and silver carp should be refrigerated immediately and cooked after 2 hours; Large fish need to be refrigerated for more than 2 hours.

Don't choose the wrong color of water in the water tank. When buying live fish in the supermarket, should I look at it? Water color? . Because it reflects the quality of water, if it is dark green or blue, it may be too much algae, which means that the water has not been changed and the water tank has not been cleaned for a long time, which may affect the health of fish. The fish in the water tank with clear water color and flowing replacement are generally more vivid.

Don't buy if the price is too low. The price is ridiculously low, so we should consider the source, quality and safety of fish. Eating spoiled fish will bring great health risks.

Sashimi should be frozen before eating. There may be parasites in sashimi, which have poor resistance to heat and low temperature, and can be killed after being frozen for 24 hours at MINUS 20℃, but the ice under the plate of sashimi can't kill parasites at all. Therefore, fish can only be eaten raw if the source of raw materials is assured enough.
