My husband said that eating raw oysters absorbs a lot of nutrients and is good for physiology, but I am afraid of infection and poisoning so I have to cook them thoroughly. Which way is better? (Trang, 25 years old, Hanoi)

Oysters are rich in vitamins, zinc, omega-3 fatty acids, cholesterol, good for both adults and children, especially men. Zinc in oysters is 6-10 times higher than other foods, very important in the male reproductive system. This is a substance that balances and regulates the hormone testosterone, helps increase testosterone production in men, good for physiology.
Zinc is also an antioxidant that neutralizes oxidants, helping sperm to be less abnormal, improving sperm quality and mobility.
However, oysters live in the marine environment and are susceptible to bacterial contamination due to environmental pollution. They are shellfish that live at the bottom of the sea, so they contain more pathogens than other species. The idea that eating raw oysters absorbs more nutrients than cooked oysters is incorrect. In addition to oysters, other types of seafood eaten raw can also cause poisoning and bacterial contamination.
Unclean oyster processing also creates conditions for bacteria to enter the body. Oysters must be soaked in clean water or salt water for about three hours to remove dirt and mud deep in the shell.
In addition to oysters, you can add vegetables such as beans, mushrooms, and meat. Oysters are nutritious, but you should not eat too much at once or too often to avoid excess zinc in the body, causing nausea, stomachache and diarrhea, bitter mouth, flu-like symptoms, copper deficiency, and susceptibility to infection.
Eating too many oysters will increase blood cholesterol levels, leading to a high risk of dangerous diseases such as heart disease, blood pressure, and stroke.
Some people with seafood allergies should be careful to avoid irritation, rash, hives, itching, abdominal pain, nausea, diarrhea.
