Oysters are members of the Ostreidae family. Popular oyster varieties are the Eastern American oyster, found in the Atlantic, and the Pacific oyster, found off the west coast of the United States and Australia. Oysters have long been valued for their mild, tangy flavor and plump meat. Oysters are often vulnerable to ocean contaminants, and in recent years, their numbers in the world's oceans have declined.
Nutritional Content
Oysters are a nutrient-rich food source. They contain 4.4 g of protein, 32 mg of zinc and 54 mcg of selenium. Including lowfat protein sources in the diet is important for reducing the risk of cardiovascular disease. Zinc is an important mineral for immune system support and wound healing. Selenium is a powerful antioxidant that protects the body's cells from free radical damage, including oxidation.
Aphrodisiac
Oysters have the reputation of having aphrodisiac properties. Legendary lover Casanova reportedly ate 50 oysters per day. The zinc content is responsible for increasing testosterone levels and stimulating the libido. The mineral also increases sperm count and increases fertility. Oysters' rich iron content also provides a source of energy that may improve sexual performance.
Hair Health
Consuming oysters improves hair health, according to Louise Chang, M.D. The shellfish contains high levels of zinc that stimulates hair growth. The mineral also neutralizes toxins and free radicals and improves the body's normal metabolic processes that can interfere with tissue production, including hair growth.
Oysters and Pregnancy
Consuming oysters may cause harm to pregnant women. Oysters sometimes absorb toxins and microorganisms that cause zoonotic illnesses in the ocean. The American Pregnancy Association advises pregnant women to avoid eating oysters. Eating raw oysters is particularly risky because the heat from cooking often destroys harmful pathogens.
