The effect of oysters is 1, which can strengthen the liver and detoxify.
The glycogen of oyster exists in the liver and muscles that store energy, and has a deep relationship with cell division, regeneration and activation of red blood cells, which can improve liver function, restore fatigue and enhance physical strength. Taurine contained in oysters can promote bile secretion, eliminate neutral fat accumulated in the liver and improve the detoxification ability of the liver.
2. Improve sexual function
Oyster contains a lot of arginine and trace element lead, which is indispensable for sperm production. Arginine is the main component of sperm production, and lead promotes the secretion of hormones. In particular, men lose 1~2mg of lead every time they ejaculate. If lead is insufficient, the number of sperm will decrease and sexual function will also decline. In addition, selenium is also an indispensable trace element for sperm production. So eating oysters can improve sexual function.

3. Congestion purification
Blood is very thick and difficult to flow, which is called congestion in Chinese medicine and is the source of all diseases. If the liver function is low, it can cause blood congestion and increase cholesterol. Taurine can promote the decomposition of cholesterol in the liver, then the excretion increases and the cholesterol content in the blood decreases. It can be seen from the above that taurine extracted from oyster has a good preventive effect on arteriosclerosis caused by blood stasis, as well as angina pectoris, myocardial infarction and cerebral infarction caused by it.
Step 4 recover from fatigue
After the fatigue substance (lactic acid) accumulates in the body, you will feel tired. As an energy source, glucose will produce lactic acid after burning, causing shoulder pain, muscle pain, headache and other symptoms. All organs where blood flows will produce lactic acid, and all lactic acid is processed through the liver, so whether the liver is healthy is very important to the human body.

Oysters are called. Milk in the sea? , rich in high-quality protein, liver glycogen, vitamins and minerals, containing more than 18 kinds of amino acids. These amino acids are rich in amino acids that can synthesize glutathione (glutamic acid, sugar gum) as anti-acidification substances. After eating oysters, glutathione is synthesized in the human body, which can remove active acids in the body, improve immunity and inhibit aging. At the same time, lead can not only inhibit cell aging, but also promote metabolism.
7. Promote metabolism

How to identify oysters

Rapid identification
1. Crassostrea gigas: The shell is large and thick, oblong or rectangular, and the dorsal and ventral edges are almost parallel, and the shell length is generally three times the height of the shell; Shell length: the left shell is 30 ~ 35cm, and the right shell is 22 ~ 30 ~ 35cm. Shell height: 9.5 ~ 10 cm for the left shell and 8.5 ~ 9.5 cm for the right shell.
