At present, it is in the cold winter, and it is also the time when crucian carp is fat and delicious.

In addition, yellow croaker can tonify blood and stop diarrhea, which is suitable for patients with anemia and chronic diarrhea.
Taboo: However, eating yellow croaker also has some taboos. The doctor pointed out that yellow croaker belongs to hair, so people who are easily angry, acne and allergic should not eat this kind of fish. In addition, eating too much is easy to produce phlegm and help poison, so patients with excessive phlegm and hemorrhoids are not suitable for eating.

4. Squid fish
Octopus is rare in Chinese mainland, mainly from Taiwan Province province. The whole octopus can be fully utilized almost 100%. Octopus is fresh and tender, with high nutritional value. It is suitable for frying, roasting, boiling, steaming, frying, salting and burning, and has the reputation of "top fish".
The name of this fish still has a history. It is said that when Zheng Chenggong came to Tainan to drive away the Dutch, he sent people to find local ingredients to enrich the military food because of insufficient military pay. One night, Zheng Chenggong dreamed that Mazu told him that there were many fish in Hougang. Sure enough, the soldiers went fishing in Hougang and gained a lot. Zheng Chenggong had never seen this kind of fish before, so he asked "what kind of fish" in Minnan. People on the side thought it was the name of a fish, so this fish was called "squid fish" from now on.
Efficacy: Chinese medicine believes that squid is pungent and flat, which can strengthen spleen and qi, stimulate appetite, nourish tendons and strengthen bones. Modern medicine believes that the meat of Ophiuchus contains iron and various amino acids, which can help the human body to make blood. Squid skin contains a lot of colloid and calcium, which is beneficial to bone growth and osteoporosis. Rich in DHA, it is expected to lower cholesterol and prevent thrombosis.
Taboo: pay attention to eating squid, because there are many and dense fishbones, so be careful when eating, so as not to stab the throat; This kind of fish should not be eaten with beer, because it is easy to induce gout attacks in patients with high uric acid; Because squid is not cold-resistant and cold-resistant, squid before winter is better.
What should I pay attention to when eating fish?
1, component
Select a size of "8 points". The size of a fish determines its taste and safety. Too small, the fish has not grown up and matured, the meat is not tender enough, and fishbones will come out. Too big means that the fish is old and the meat is rough, and many harmful substances may accumulate in the body. Therefore, it is more appropriate to buy fish with the size of "eight points".
Step 2 color
The fish is too red and white to eat. Because of the different kinds of fish, there are red-fleshed fish such as tuna and white-fleshed fish such as hairtail, but if the color of fish is too bright red or bright white, it is probably the "credit" of dyes.
Step 3 refrigerate
Now kill the live fish and put it before eating. The quality of freshly slaughtered fish is not the best, because fish will have a process of "acid discharge" and it will take some time to be more delicious. Small fish such as grass carp and silver carp should be refrigerated immediately and cooked after 2 hours; Big fish need to be refrigerated for more than 2 hours.
4. apophyllite
Don't buy those with cloudy eyes and gray cheeks. When buying "chilled fish", you should first observe its eyes and gills. 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, sometimes the bleeding in the eye is red, and the gills are dark and grayish red or grayish purple. Rotten fish eyes collapse or shrivel, cornea atrophy or rupture, and gills are brown or grayish white.
My conclusion is that eating fish is good for health and brain function. But in fact, the nutritional value of different parts of fish is different. For example, fish brain can promote brain development and prevent Alzheimer's disease. But when eating fish, you need to pay attention to weight, color, refrigeration and fish eyes. There are also many precautions when eating fish. If we don't pay attention, it will affect our health.
