As the saying goes, [eating meat is better than eating fish]. Some studies have pointed out that eating red meat (red-looking meat, pork, beef and mutton are all included) is closely related to colorectal cancer.
But protein always needs to be supplemented. Especially as people get older, they are more likely to lack protein due to changes in eating habits. Then, eating fish once or twice a week is a good idea.
A big, ugly guy
Epinephelus is a large family. The vast majority of Epinephelus belong to tropical and subtropical fishes. There are about 60 species distributed along the coast of China, mainly in the southeast coast of China and the waters of Xisha and Nansha. Among them, more than 10 species are most commonly eaten and cultured on a large scale. Friends in the south may know them well.
Grouper has a thick body, a very large mouth, and many [large heads] are also quite large, reaching more than one meter in length. In addition, grouper is often grayish black and looks ugly. Of course, there are also smaller species.
Now human beings have also cultivated many grouper. In deep sea fishing activities, grouper is a very popular fish. In addition, grouper usually takes 10 years to reach adulthood, and many grouper we eat are actually juvenile fish that have not yet reached adulthood.
The nutrition is comprehensive and rich, and the value is very high.
In fact, although grouper does not look good, its nutritional value is still very good.
1. The meat quality of grouper is tender and white, similar to chicken, and is known as [sea chicken]. Grouper is rich in protein and has a variety of delicate amino acids. The meat quality is especially delicious and popular.
2. Epinephelus is a kind of fish with low fat and high protein. Replacing beef and mutton we usually eat with Epinephelus can reduce fat intake. For the elderly with hyperlipidemia, poor cardiovascular system and hypertension, it is a particularly good choice.
3. The content of mineral zinc in grouper is also excellent, which is of great significance for promoting reproductive health.
Eat grouper, watch out for ciguatoxin
Although grouper is good, you should be careful when eating it, because there may be a natural dangerous molecule in grouper-ciguatoxin.
Grouper itself is not toxic. Ciguatoxin comes from seaweed. Small fish eat seaweed and big fish eat small fish. This is how grouper eats the toxin.
It is impossible to judge whether fish is poisonous only in terms of its appearance, smell or meat quality. Moreover, the most overwhelming thing is that ciguatoxin is very heat-resistant, and even if you cook, freeze or dry at high temperature, you cannot remove the toxin.
Ciguatoxin is a very strong neurotoxin. Eating 0.1 micrograms will poison people.
In order to avoid poisoning, four points must be paid attention to:
1. Be careful when you eat,Be especially careful of big fish weighing more than 3 kg..The bigger the fish is, the more toxins may accumulate in the body.
2. Try not to eat fish head, fish eggs, fish viscera and other parts. Because ciguatoxin is abundant in fish head, fish eggs, fish skin and fish viscera, which can be as high as 50 to 100 times as much as other parts.
3. When eating grouper, it is best not to drink alcohol, eat peanuts and beans. This may deepen the poisoning symptoms of ciguatoxin.
4. If poisoning and discomfort symptoms occur after eating grouper, you must seek medical treatment as soon as possible.
Of course, grouper is still a kind of nutritious fish, and now there are many artificial breeding, it will be safer, not completely can’t eat. If you want to eat, you’d better eat less each time, and try to buy smaller grouper when choosing. Remember to throw away the head, skin, viscera and eggs when eating.
