The edible part of crab is crab meat, which has high nutritional value. According to the nutritional composition of this part, the protein can be as high as 19%, while the fat part that dieters care about is only 0.9%.
If you want to supplement protein, crab meat is a good place. When everyone is eating, why not eat all the crab meat? Very clean. If it is a crab leg, the meat is not easy to take, so it can be pointed out with a crab, which is high in nutrients.
In addition, for people with poor cardiovascular system, crab meat can also be eaten in moderation. This is because crab meat contains a lot of unsaturated fatty acids, which is comparable to deep-sea fish in this respect. Proper diet is beneficial to cardiovascular health.
Followed by crab paste or crab roe, crab roe and crab roe also contain essential fatty acids needed by human body, especially linoleic acid and arachidonic acid, in which the linoleic acid content is still relatively high. But what is bad for people is the fat and cholesterol. In a crab, crab roe and crab paste should be paid special attention to and eaten as little as possible.
In addition, I also want to remind you that there are four parts in the crab that should not be eaten at all.
1, crab gills: Crab gills are a part of crabs, and many people know that they can't be eaten. This is because crabs breathe like other animals, and the place where they breathe is crab gills, which can help crabs breathe, but this part is also used to filter harmful substances such as impurities in water. This place may contain mud, sand and other ingredients.
Therefore, when people eat crabs, this part should not be eaten. Moreover, before making crabs, everyone should pay attention to cleaning them. If the crab shell is dirty, you can also clean it with a small brush.
2, crab intestines:
Crab intestines are in the triangle area of crabs, and there is also a lot of crab excrement in this area. Don't eat them easily.
3, crab stomach:
The crab's stomach is in the triangle area of the crab, and there is a bony place, similar to a small bag, which is the crab's stomach. This place is not recommended to everyone.
4, crab heart:
Crab heart is a hexagonal plate of crab. If it is crab yellow, the crab heart is in the middle of crab yellow. You can see it when you eat. Don't put your mouth down easily.
