Because it can promote the formation and secretion of hormones, it also has a good effect on physiological disorders, non-pregnancy and menopausal disorders.
2. Supplementing various elements needed by the human body
Oysters are the best food for calcium supplementation and are rich in phosphorus. Because calcium needs the help of phosphorus when it is absorbed by human body, it is beneficial to the absorption of calcium. Oysters can supplement zinc, and the best way to prevent zinc deficiency is to eat more foods rich in zinc, which has the highest zinc content. Oysters contain vitamin B 12, which is lacking in general foods. The diamond element in vitamin B 12 is an indispensable substance to prevent pernicious anemia, so oysters have active hematopoietic function.

Taurine, DHA and EPA contained in oysters are important nutrients for intellectual development.
Glycogen is a form of human energy storage, which can improve the efficiency of physical and mental activities.

These amino acids can detoxify and remove toxic substances from the body, while aminoethanesulfonic acid can reduce the blood cholesterol concentration, so it can prevent arteriosclerosis.
5, rich in trace elements and glycogen, these nutrients are good for promoting the growth and development of the fetus, correcting the anemia of pregnant women and restoring the physical strength of pregnant women.
6. Oyster extract.
These extracts can obviously inhibit platelet aggregation, reduce TXA2 content in blood of patients with hyperlipidemia, promote the secretion and utilization of insulin, enhance the sensitivity of malignant tumor cells to radiation and inhibit their growth.

How to choose oysters 3
Generally speaking, oysters with good quality are those with black and white shells. After hulling, the meat is complete and plump, with black edges, and the meat is shiny and elastic.
If the ligaments of life are yellow or white, they are not fresh.
Are oysters "alive"
When choosing oysters, be sure to find those who have the strength to close the shell tightly.
When choosing, first look at whether some of these oysters are slightly open. Live oysters shut up at the first sign of trouble, so they also pat the edge of their shells. If they close immediately, they will be fresh oysters. If you don't even have the strength to close the shell, you must be dead.
Oysters suit themselves.
If you prefer a softer taste, choose a smaller oyster. If you buy oysters, don't soak them in fresh water or seal them in airtight plastic bags. Instead, put them in a dry container and cover them with a wet cloth to keep the humidity of oysters and the temperature of the environment (preferably stored in a refrigerator at 5 to 8 degrees Celsius). These oysters can last at least 1 week, and the fresh life is rare and delicious!
Oysters are "real"
There are assembled oysters on the market now, which are fake oysters.
So how can we identify this scam and stop being a fool? When choosing oysters, stir the oyster meat with chopsticks. If the meat and shell are closely connected, it is definitely not "assembling oysters."
If the barbecue shop doesn't let customers choose oysters, or if they don't see real oysters when ordering, there may be something fishy.
Roasted oysters are usually connected with meat and shells, so be careful if they are separated.

Will eating oysters give birth to a son?
It is impossible to manipulate boys and girls, but according to research, some factors can still have a certain impact on it, such as controlling diet.
Studies show that X chromosome likes acidic environment and Y chromosome likes alkaline environment.
Therefore, if you want to have a boy with a high probability, women can eat more alkaline foods or foods containing more potassium and sodium, such as all kinds of freshly squeezed juice, soda biscuits or root foods; Men should eat more acidic foods, such as eggs, milk (or other dairy products), beef, aquatic products, almonds and so on.
Oyster is a strongly acidic food, which has the function of latent yang and nourishing yin.
Studies have shown that oysters are rich in amino acids, zinc and other trace elements, and are very effective fortified foods.
Male sperm y contains a lot of zinc. When zinc is insufficient in the body, it will affect the quantity and quality of sperm. The zinc content in oysters is the most abundant, and the zinc content in a small oyster can meet the needs of one day, thus enhancing the sexual ability of men.
In this way, eating oysters seems to really increase the probability of having a boy. But in fact, it is not feasible to control boys and girls through diet.
