Shrimp line, shrimp head and shrimp skin, which part can't be eaten? The answer is not what you think.

When eating shrimp every day, you may suddenly see a dark shrimp line. After all, even if you cook at home, you can't guarantee that the shrimp line is completely cleaned.

At this time, many people began to hesitate whether to eat directly or clean up the shrimp line before eating. Black shrimp line, will it be a problem if you eat it in your stomach? The nutritionist in the following explosion nutrition class will talk to you:

Like most people think, shrimp line is shrimp shit. Therefore, it is really "dirty" in theory, and it may contain bacteria, so it is recommended to remove it.

But the shrimp line does not contain any toxic substances, and the bacteria inside will be killed after high temperature treatment. Therefore, if everyone eats thoroughly cooked shrimp, it is no problem to eat shrimp thread, and there is no need to worry about health, but it may make people feel a little disgusting.

In addition, apart from the shrimp line, whether the head and skin of shrimp can be eaten has always been controversial. For example, shrimp heads may be inedible in the eyes of many people. But if you have been to Chengdu, you will find that most people here eat shrimp heads.

So is the shrimp head edible? The nutritionist of the explosion nutrition class told everyone that it depends on the specific situation:

Because shrimp will enrich heavy metals in the environment, and mainly concentrated in the head, eating shrimp head does have certain risks. But if there are no heavy metals in the environment and feed, how can shrimp have heavy metals?

Generally speaking, as long as it is a regular cultured shrimp, the shrimp head can be safely eaten. In fact, in many high-end restaurants, there are dishes mainly with shrimp heads. In some areas of our country, there is a custom of eating shrimp paste.

However, if you get shrimp from unreliable sources, such as shrimp bought from street vendors or crayfish caught in the gutter, you'd better not eat shrimp heads.

Finally, talk about shrimp skin. The skin of shrimps mentioned here refers to the skin of big shrimps, such as the skin of new shrimps, and can also be understood as shrimp shells. The "shrimp skin" often mentioned in life is a kind of dried product made of shrimp, called hairy shrimp.

In fact, the main ingredients of big shrimp skin are minerals such as protein and calcium, which are of course edible and healthy.

But generally speaking, the taste of big shrimp skin will be poor and difficult to swallow. Shrimp skin can be fried crispy and chewy unless it is fried.

But once the shrimp is fried, its oil content will be greatly increased and its calories will be higher. Control the amount when eating to avoid obesity.
