Nutritional Value of Oysters
In traditional medicine, oysters are believed to have a cooling nature and are non-toxic. This seafood is said to have aphrodisiac properties, nourish the essence, nourish yin and blood, and treat insomnia caused by heat. It is also beneficial for hot and dry individuals, women experiencing perimenopausal disorders, dizziness, and postpartum anemia.
Modern scientific research has revealed that oyster meat is rich in vitamins, minerals, and organic compounds, including vitamin C, vitamin D, B-group vitamins, zinc, iron, copper, selenium, phosphorus, potassium, protein, omega-3 fatty acids, and antioxidants.
Who Should Not Eat Oysters
The Centers for Disease Control and Prevention in the United States advises individuals with the following symptoms to refrain from consuming oysters:
– Those with a history of seafood allergies
– Individuals with chronic liver disease
– People with underlying medical conditions who are taking immunosuppressant medications

Oysters have high nutritional value but may not be suitable for everyone.
– Individuals with gout or arthritis should limit their consumption of oysters.
– Those with weak spleen and stomach, indigestion, or diarrhea should avoid oysters as they are cooling in nature and may cause stomach discomfort and diarrhea.
– Pregnant and breastfeeding women should consume oysters in moderation due to the potential presence of high mercury levels. Additionally, raw oysters should be avoided to prevent parasitic infections.
Additional Notes on Oyster Consumption
– Do not overeat oysters: While oysters are highly nutritious, excessive consumption may lead to zinc and cholesterol overload. 170 grams of oyster meat can contain up to 85 mg of cholesterol.
– Limit raw oyster intake: Whether wild-caught or farmed, raw oysters may harbor parasites and bacteria, increasing the risk of gastrointestinal illnesses, such as stomach inflammation, dysentery, and cholera.
– Use mustard sparingly: Although mustard is a common condiment for seafood, adding too much can irritate the mucous membranes of the nose and throat. It may also cause stomach irritation in individuals with digestive issues, stomach ulcers, or intestinal inflammation.
