About Oysters
Oysters are bivalve mollusks found primarily in marine habitats worldwide, particularly along coasts of Europe, Asia, and the Americas. They are known for their delicate texture and briny flavor, often consumed raw, grilled, or in soups. Oysters are nutrient-dense and low in calories, providing high-quality protein (5.71g per serving), essential minerals like calcium (59mg) and iron (4.61mg), and healthy fats. They are also rich in zinc and selenium, but notably lack vitamin C and fiber. Oysters have held culinary and cultural significance for centuries, particularly in French and Japanese cuisine, where they are considered a delicacy.
