What are the effects and functions of shells

Shells are a type of seafood. This kind of food will become very delicious after cooking, but it is best to retain the original deliciousness of the shells so that the nutrients will not be lost.

People can absorb adequate nutrients after eating shellfish, which is very beneficial for maintaining the body's metabolism.

The effect of shells

1. Shells can purify the blood

Purifying the blood is one of the important functions of shells. The unsaturated fatty acids contained in shells are known as blood vessel scavengers. They can clean out various toxins in human blood and reduce the accumulation of cholesterol in blood vessels. Regular consumption can soften blood vessels, purify blood, and prevent the occurrence of various cardiovascular diseases.

Shells contain some natural DHA, also known as docosahexaenoic acid, which is often called brain gold. After being absorbed by the human body, it can promote the development of brain nerves and optic nerves, and can also improve people's memory. It is most suitable for people who use their brains frequently. In addition, middle-aged and elderly people can reduce the incidence of Alzheimer's disease by eating more shellfish ingredients.

The main components of shells are 95% calcium carbonate and a small amount of chitin. Generally, it can be divided into three layers. The outermost layer is the dark brown cuticle (shell skin), which is thin and transparent. It has the function of preventing carbonic acid erosion and is composed of chitin secreted by the edge of the mantle; the middle layer is the prismatic layer (shell layer), which is thicker and composed of prismatic calcite secreted by the edge of the mantle. The outer and middle layers can expand the area of ​​the shell but do not increase the thickness; the inner layer is the nacre (bottom layer), which is composed of leaf-shaped aragonite (aragonite) secreted by the entire surface of the mantle. It has a beautiful luster and can thicken as the body grows.
