The silver scale on the hairtail body surface is actually a layer of epidermis formed by special fat, which is called silver grease. This kind of silver fat has very high nutritional value and is a particularly high-quality fat. Experts have shown that this kind of silver scale is rich in nutrients such as protein, iron and iodine, and it also contains a lot of lecithin and a variety of unsaturated fatty acids, which has natural anticancer components. After eating the silver scales on hairtail regularly, the skin will become very delicate, smooth and elastic, and at the same time, the hair will become black and shiny, which also has certain effect on delaying the aging of the brain.

In addition, it also has a good protective effect on the cardiovascular system and can effectively prevent diseases such as hypertension.

According to the nutrition theory, when eating hairtail, you don't need to scrape off the scales of hairtail (including the layer of white wine), because the scales of hairtail are not only rich in nutrients such as protein, iron and iodine, but also contain more scales and a variety of unsaturated fatty acids, and these substances have the function of preventing human arteriosclerosis.

Hairtail scales can also enhance the vitality of skin cells, which is a rare edible beauty product. Therefore, the scales of hairtail don't have to be scraped off.

However, people have a habit of eating. If they don't remove the scales (or the white layer), many people will feel unclean, and some people will even feel sick.
